Moisture levels and densities on bean yield
type: item
description: The research evaluated the effect of three soil moisture levels (30%, 70% and 100% of usable moisture) combined with two densities (30 and 40 plants m-2) on the yield of the bean (Phaseolus vulgaris L.) crop, variety Pinto Saltillo, under drip irrigation in Salinas de Hidalgo, San Luis Potosí. The design used was a 3 × 2 factorial design with three replications, totaling 18 experimental units. The variables analyzed included plant height, stem thickness, leaf dimensions, number of pods, plant dry weight, pod weight and grain yield. The treatment with 30% moisture (90 000 L ha-1 per irrigation) and 30 plants m-2 presented the best performance, reaching 47 cm in height, 15 pods per plant and a yield of 118 g m-2 (1 180 kg ha-1). Treatments with 70% (210 000 L ha-1 per irrigation) and 100% moisture (300 000 L ha-1 per irrigation), together with higher density, showed negative effects due to intraspecific competition. There were no significant differences in yield across moisture levels, even when irrigation volume was doubled or tripled. Significant correlations were identified between height and number of pods (r= 0.716), pod weight and grain yield (r= 0.987) and leaf dimensions (r= 0.887). The results indicated that moderate water stress and adequate density favor bean development and allow efficient water use. The study provided technical evidence to optimize water management and agronomic practices in semi-arid regions.

The export of the guava from Mexico to the world market
type: item
description: Guava is a fruit widely accepted worldwide and in 2023, Mexico consolidated its position as the second-largest global exporter, with a value of 577 934.18 USD, confirming its high international competitiveness. The research aimed to analyze the competitiveness of Mexican guava in international trade, identifying its position and formulating alternatives that strengthen its insertion into international trade. The research was conducted by calculating growth rates and trade competitiveness indices for the period 2000-2023, using production and foreign trade data. The results showed that the indicators were positive: the trade balance remained at 1, which confirms that Mexico is an exporter with competitive advantages; the tradability indicator was 0.34, evidencing an excess of exportable supply; the trade dependence coefficient was 0, which reflects food self-sufficiency; and the degree of export openness reached 0.035, pointing out the existence of exportable surpluses. Overall, these results indicate that guava production in Mexico is expanding, with a marked export specialization and a solid competitive position in the international market. t.

Evaluation of drought indices in crystalline wheat genotypes
type: item
description: Wheat is an important cereal for the human diet due to its protein and caloric contribution; however, production by 2050 will be compromised by the effects of climate change, where periods of drought will be increasingly frequent, which will affect both rainfed and irrigated crops. Based on this problem, the need to develop water-stress-tolerant crops arises; therefore, several studies consider the estimation of drought indices as tools to select genotypes tolerant to water deficit. This study aimed to evaluate six drought indices in 15 crystalline wheat genotypes under two irrigation depths in two localities in Coahuila and Nuevo León during the autumn-winter 2023-2024 agricultural cycle. The evaluated treatments were two irrigation depths for each locality: IR1 of 37.27 cm and IR2 of 20.92 cm for Zaragoza, Coahuila, and IR1 of 42.24 cm and IR2 of 19.35 cm for Navidad, Nuevo León. The experimental design consisted of randomized complete blocks arranged in split plots with two replications. The water stress tolerance index was the one that best related to grain yield under water-deficit conditions for Zaragoza, Coahuila. The tolerance index was the one that was best associated with grain yield under water-stress conditions for Navidad, Nuevo León. 715 and 738 were the most tolerant to water stress in both localities.

Antagonistic microorganisms as management of Fusarium oxysporum wilt of blackberry
type: item
description: In the states of Michoacán, Mexico and California, USA, blackberry (Rubus sp.) production is affected by wilt, which causes the loss of thousands of hectares. In the present work, the causative agent of the disease was identified and control alternatives with antagonistic microorganisms were proposed. In 2022, the causative agent of the disease was isolated and morphologically identified from an orchard in Tocumbo, Michoacán. A preliminary laboratory bioassay was performed with strains of B. subtilis, B. amyloliquefaciens, P. fluorescens, and Trichoderma spp., native to Tacámbaro and Taretan, Mich. The outstanding strains were tested in a greenhouse on plants of blackberry cv Tupy as a preventive measure and as a control, under an experimental design of randomized blocks with six repetitions. In the preliminary tests, all the strains used showed an inhibition of the mycelial growth of the pathogen greater than 50%, with Trichoderma sp. from Tacámbaro, B. subtilis and P. fluorescens standing out. In the tests carried out in situ, preventively applied treatments decreased the incidence of wilt by 57% to 66%. In terms of severity and plant height, Trichoderma sp. stood out, while the percentage of root necrosis decreased by 56% to 70% with all treatments. Control treatments also showed antagonistic efficacy, although to a lesser extent, they decreased the incidence of wilt by 2 to 58% and the percentages of root necrosis by 19 to 62%. Antagonistic microorganisms can be incorporated as a comprehensive management strategy with high efficiency.

Phytoparasitic nematodes in broad bean crops in eastern Puebla
type: item
description: The broad bean is one of the most important crops in the Central Mexican Plateau due to its adaptation to edaphoclimatic conditions and its high nutritional value in the diet of the inhabitants of this region. Nonetheless, the yields obtained are low compared to the world average. Phytoparasitic nematodes are one of the main constraints to broad bean production in other parts of the world; however, its presence in this crop is unknown in Mexico. In this work, phytoparasitic nematodes associated with broad bean crops were identified and quantified in 10 farms in the municipalities of Tepeyahualco and Cuyoaco, Puebla, and in plants germinated in sterile soil from seeds from different areas in 2022. The following six genera of phytoparasitic nematodes were found: Criconemoides, Ditylenchus, Helicotylenchus, Hoplolaimus, Pratylenchus and Zygotylenchus. The most abundant genera were Ditylenchus and Pratylenchus, with a population density of 11 and 7 specimens per 100 cm3 of soil and 159 and 60 specimens per 100 g of plant tissue, respectively, and they were found in all sampling sites. The population density of Ditylenchus exceeds the economic threshold of the crop; in addition, specimens of this genus were found in plants germinated in sterile soil. The results show that Ditylenchus is distributed throughout the sampled area and can affect yield. Further studies are needed to determine the identity of nematode species and their distribution in other production areas.

Yield, biomass and phenology of the cross between wild and domesticated beans
type: item
description: Hybridization makes it possible to improve beans (Phaseolus vulgaris L.). Lines with a broad genetic base are an advantage for obtaining new varieties. P. vulgaris in Mexico, like corn, is one of the staple crops that fulfills various food functions and is subject to constant improvement. The present study aimed to evaluate the progeny or lines obtained from the cross between a wild and a domesticated parent, grown in greenhouses and hydroponics to determine seed yield, biomass production, and their phenology. The study was carried out in 2019 at the Montecillo Campus, College of Postgraduates. The assessment included wild beans (S13), domesticated beans, registered as Negro Tacaná, and five lines (53b, 51b, 118b, 111, and 3.3) product of the cross of S13 with Negro Tacaná. Each parent and each line was considered as a treatment and were distributed in a completely randomized design. Lines 118b and 3.3 produced the highest seed yields, 225.3 g plant-1on average; the wild parent, the domesticated one, and lines 11.1 and 51b intermediate yields (150.5 g plant-1), and line 53b the lowest yield 98.6 g plant-1. The S13 parent had the highest number of seeds per pod and weight of one hundred seeds, whereas this was the opposite in Negro Tacaná. The yield and time to occurrence of the phenological stages was a response to the environment and the management of the crop, which allowed the maximum expression of its genetic potential.

Behavior of hybrids, improved varieties and native varieties of yellow corn in Chiapas
type: item
description: In 2016, Mexico imported almost 13 million tons of yellow corn, valued at more than 2.3 billion dollars. However, imports could be reduced or eliminated if the yellow-grained varieties and hybrids generated by the National Institute of Forestry, Agricultural and Livestock Research were grown. The study aimed to identify the best hybrid and the best variety of yellow corn that the National Institute of Forestry, Agricultural and Livestock Research has released for the Mexican tropics, where more than 420 000 ha are planted, and 2.1 million tons of yellow corn are produced. During the spring-summer agricultural cycle of 2018, 21 genotypes were evaluated in three localities in Chiapas; the hybrids H-443A, REMACO15A and H-386A stood out statistically with grain yields of 5.748, 5.608, and 5.514 t ha-1 and equaled two of the control commercial hybrids; of the improved varieties, Población Amarilla C1 stood out with 4.9 t ha-1 and of the native varieties, the Olotillo Amarillo-1 variety, from Ocozocoautla, stood out with 3.1 t ha-1.

Sustainable production systems strategies in the Mixteca Alta region of Oaxaca
type: item
description: In Mexico, the problems faced by rural communities lie in their high institutional economic dependence. The integration and participation of producers and society represent an opportunity to use natural resources sustainably. The objective was to describe proposals for sustainable production practices as possibilities for producers in the rural communities of Chalcatongo de Hidalgo to apply in the management of productive projects and in the improvement of the local economy. Forests have the capacity to capture carbon dioxide (CO2), which is traded in exchange for economic resources. Nevertheless, it is required to have a solid organization, strong commitment, constant effort and effective collaboration of social capital. After a review of relevant documents, database analysis, and participant observation, it was determined that it is feasible to apply sustainable productive practices to the management of sustainable projects and local economies; however, commitment, awareness, responsibility and the implementation and strengthening of social capital are essential.

Microbial contamination during stages of in vitro propagation of Agave angustifolia Haw.
type: item
description: When Agave angustifolia stem tissues are established in vitro, microbial contamination frequently occurs; therefore, the use of antibiotics to solve this problem was evaluated. The purpose of this work was to determine the percentage of stem tissues that had an aseptic establishment and exhibited morphogenetic response in three situations: 1) during in vitro establishment (stage I); 2) in explants in which organogenesis with shoot formation occurred in stage I but were contaminated with bacteria, and these were treated with antibiotics to eliminate contamination; and 3) in aseptic adventitious shoots obtained in stage I and transferred to propagule multiplication medium (stage II). The percentages of aseptic cultures, viable tissues, and organogenic response were evaluated. The results showed that only between 3.68 and 8.73% of stem tissues were aseptic during stage I. However, by applying antibiotics to shoots already formed but contaminated with bacteria at this stage, asepsis was recovered in 52.5% of the cultures. On the other hand, adventitious shoots that were aseptic from stage I and transferred to the multiplication medium (stage II) maintained asepsis at 89.88%; all were viable and showed formation of new shoots. These results indicate that antibiotic treatment in already induced stem tissues is an effective strategy to rescue contaminated cultures, and that transferring aseptic shoots to the multiplication stage allows maintaining aseptic cultures with morphogenetic response.

Alternative agroforestry for improving the semi-arid climate of Salamanca
type: item
description: The research was conducted during 2022 and 2023 in the northern region of the municipality of Salamanca, Guanajuato, in the localities (Los Hernández, Los Razos de Ancón, Los Cenizos and La Compañía) corresponding to the semi-arid zone, where production systems are highly vulnerable to accidents, mainly due to water scarcity. In order to know their complexity and propose alternatives for improvement, a diagnosis of the production systems was carried out. The methodology used was the agrarian diagnosis, and the tools employed to obtain the information were semi-structured interviews, geographic information systems, and the 2020 Population and Housing Census. The results showed three principal agroecosystems: irrigated agriculture (agricultural), rainfed agriculture (agrosilvopastoral), and rangeland (silvopastoral), as well as 10 cultivation or rearing systems. In order to understand their complexity and propose alternatives for improvement, a typology of production units was developed, identifying three categories that were very similar to one another yet distinct. To determine economic indicators, the methodology generated by Dufumier (1996) and Apollin and Eberhart (1999) was used, which aims to understand the functioning of production systems and their prospects of evolution. It was concluded that the stability and permanence of production units depend on the ways of using available resources, whereas their differentiation is a function of the availability of water, the degree of intensification of labor, the available surface area, and the use of technology.

Determination of sample size in polyembryonic citrus seeds using robust methods
type: item
description: The percentage of polyembryonic seeds and the number of embryos per seed (NE) are variables commonly used to estimate the degree of polyembryony in citrus, a characteristic used as an indicator of clonal or vegetative propagation of selected genotypes. However, many studies omit the description of the methods used to determine the appropriate sample size in the quantification of these variables. The purpose of this work was to propose a robust statistical methodology for calculating the optimal sample size in polyembryonic studies in citrus using the maximum distance method and the F-test. Five citrus genotypes (C-35 citrange, Volkamer lemon, Amblicarpa mandarin, Valencia orange and Mineola tangelo) were evaluated over two harvest cycles (2020 and 2021) by counting the number of embryos in 100 seeds per genotype. Since the variable of the number of embryos per seed was not normally distributed, the maximum distance method was applied using coefficients of variation calculated with the winsorized mean and a nonparametric bootstrap procedure. The results indicated optimal sample sizes of 26 to 28 seeds, with coefficients of variation of 6% to 11%, depending on the genotype. It was concluded that, for the genotypes evaluated, analyzing samples of up to 50 seeds is sufficient to estimate the degree of polyembryony accurately.

Characterization and phenological prediction of tropical black bean genotypes
type: item
description: The phenological characterization of black bean varieties generated by the Bean Program of the National Institute of Forestry, Agricultural and Livestock Research for southeastern Mexico is conducted by quantifying the number of days after sowing required to reach the different stages of development. This characterization is imprecise for contrasting environments. This study aimed to characterize nine advanced lines and two varieties of opaque black beans by using the number of days after sowing and the index of growing degree-days necessary to achieve the stages of flowering and physiological maturity and to compare the accuracy of the number of days after sowing and the growing degree-days to predict phenology. The number of days after sowing and the growing degree-days required by the genotypes to reach the flowering and physiological maturity stages were quantified across nine environments in southeastern Mexico. The ability of five mixed models was evaluated, considering the number of days after sowing, growing degree-days and environment as fixed effects and genotype as a random effect, to predict the phenological stages of the lines and varieties. Four lines were earlier than Negro Grijalva (1 892 growing degree-days), with an average of 1 859 growing degree-days; in contrast, four others obtained an average of 1 902 growing degree-days, higher than Negro Grijalva but lower than Negro Comapa (1 920 growing degree-days) and only one line was later than both varieties (1 976 growing degree-days). The best model for predicting phenology was the one that considered only the growing degree-days, regardless of the environment. It was concluded that growing degree-days are more accurate than the number of days after sowing for predicting the flowering and physiological maturity of the genotypes in the different evaluation environments.

Influence of Sargassum spp. extract on germination and antioxidant activity of tomato seedlings
type: item
description: In recent years, the macroalga Sargassum spp. has become an economic and environmental problem in several coastal regions. Nonetheless, due to the wide variety of bioactive compounds it possesses, it has been proposed as a sustainable alternative in agriculture, as it can improve seed germination, nutrient absorption, and photosynthesis, and mitigate biotic and abiotic stress. The objective of this study was to evaluate the effect of priming tomato seeds with aqueous extracts of Sargassum spp. on germination, vigor, biomass, photosynthetic pigments and some indicators of the antioxidant system of seedlings. The concentrations of the extracts were: 0.5, 1.5, 2.5 and 3.5%, and a control with distilled water. The results indicate that the extracts improved germination, vigor, phenolic compounds, flavonoids, antioxidant capacity and photosynthetic pigments. There were no significant improvements in biomass. These results suggest that applying Sargassum spp. extracts may be an ecological alternative to improve germination parameters and stimulate the synthesis of secondary metabolites in tomato seedlings.

Quality, morphometry and mineral composition of Agave spp. seeds in Oaxaca
type: item
description: The seed is a reproductive organ of vascular plants from which a new individual is generated. Quality tests were conducted on seeds of five agave species, and morphometry and nutritional content were determined; the latter was compared with the soil’s mineral content. The collection of seeds and soil was carried out in some localities in the Central Valleys and Mixteca regions of Oaxaca during 2024. A. potatorum and A. salmiana presented the highest germination values, with 65.5% and 58.3%, respectively; A. americana significantly showed the highest weight of 1 000 seeds, with 11.2 g ±0.96; in moisture content, A. salmiana and A. karwinskii showed higher values. A. nussaviorum presented the highest weight gain with 389.4%; in the determination of viability, A. potatorum reflected the highest value with 72.8%. In the morphometric analysis, a cumulative variation of 61.1% was detected, with an overlap of ellipses between the species. A higher concentration of Zn, Fe, and Na was found as predominant elements in the seed; their values were not related to the concentration in the soil. The soil’s physical and chemical characteristics were diverse. In a principal component analysis with all variables, the first three components accounted for 89% of the total variance. With this methodology, the variables that reduce dimensionality were identified, giving greater significance to certain minerals.

Optimizing nitrogen ratios for blueberry cultivated under saline medium
type: item
description: Blueberry (Vaccinium corymbosum L.) production in Mexico is expanding rapidly, yet nitrogen management and salinity stress remain major challenges. This study evaluated the effects of ammonium (NH4+) and nitrate (NO3-) fertilization, with or without sodium chloride (NaCl, 30 mM), on growth, yield, and fruit quality of ‘Biloxi’ blueberry grown in coconut fiber substrate. A completely randomized 3x3 factorial design plus control was applied, varying nitrogen source, concentration (75% and 100%), and salinity. NH4+ significantly increased biomass (121.2%), flower production (316%), fruit number (231%) and yield (162.7%) compared with NO3-. A 100% N rate enhanced shoots (19.5%) and fruit count (43.4%) but reduced fruit size. Salinity reduced fruit number (-70.3%) and yield (-53.1%) without affecting vegetative growth. Significant interactions among nitrogen source, concentration and salinity influenced flowering, quality and agronomic traits. Results indicate NH4+ based fertilization improves blueberry productivity under saline conditions, supporting more efficient nitrogen management strategies.

Example for the analysis of a series of experiments arranged in balanced complete blocks
type: item
description: There is little published information in some series of experiments, such as in the randomized complete block design in a balanced complete block arrangement (RCBD-BCBA). This study presents a hypothetical example to apply the methodology published in González et al. (2024b), which is an extension of a case formulated by Gomez and Gomez (1984). The analysis of variance and the comparison of means between treatments using Fisher’s least significant difference test correspond to the analysis of the data combining the information of two trials, based on the statistical model that was chosen for the present research, the validation of the results generated can be done with other statistical packages, such as Info-Gen, SAS, OPSTAT, STAR, PBTools, or Agrobase, among others.

Productive projection of forage corn in Mexico and the state of Veracruz
type: item
description: Corn is a crop of great importance in Mexico because it is used for both human and animal consumption, positioning itself as one of the three most important forage crops due to the energy value it contributes to the diets of dairy cattle. The study aimed to examine trends in forage corn production at the national level and in the state of Veracruz from 1980 to 2023 in order to forecast the availability and supply of feed for the livestock sector using predictive models (ARIMA). The information was obtained from the database of the Agrifood Information Consultation System, covering the historical series at the national level and for the state of Veracruz. The exploratory data analysis technique was used to identify trends and seasonalities; subsequently, predictive time series models were built using the ARIMA model, using the RStudio forecast library. The results showed an upward trend in forage corn production. At the national level, forage production under irrigated conditions will present a sustained growth trend; in contrast, under rainfed conditions, unstable variations will be observed over the next decade, with a projected decrease of 1.57%. In the state of Veracruz, projections indicate that corn forage production under irrigated and rainfed conditions will maintain a stable trend over the next decade. Yields per hectare are estimated at 19.57 and 23.87 tonnes, respectively, suggesting productive stability associated with relatively constant edaphoclimatic and management conditions in the region. It is concluded that the use of predictive models is a reliable tool for modeling corn forage production, providing the agricultural and livestock sectors with a planning instrument that contributes to reducing agricultural risks in the short and medium term.

Associativity index in coffee-growing organizations in the Cauca Department, Colombia
type: item
description: In Colombia’s rural sector, collective action presents itself as a fundamental axis for generating shared benefits and mobilizing territorial resources. In this framework, associativity represents a key strategy for strengthening it, especially in small-scale coffee-growing scenarios. In the Cauca Department, where 99% of coffee growers are small producers organized mostly in associative models, it is a priority to understand how associativity is configured and expressed in their organizational structures. This research aimed to estimate and apply the associativity index to three coffee growers’ organizations (ASOMEDACS, FCC, and ASPROSI) in order to understand the particularities of their collective dynamics. The study was conducted from 2023 to 2024, using a multiple case design with a mixed approach. A structured survey was administered to 38 coffee-grower leaders, based on ten indicators validated by institutional actors in the sector. The analysis integrated a weighted composite index and statistical tools (Anova and Tukey’s HSD test). The results revealed significant differences among the organizations, with ASPROSI standing out with the highest index (76.41), indicating greater internal cohesion, a solid organizational structure and participatory links. These findings suggest that a higher index of associativity may reflect a greater organizational capacity to generate collective action. The proposed methodology offers a replicable and relevant tool for evaluating organizational processes in rural territories and proposes a future line of research on the relationship between associativity and resource activation within the framework of localized agrifood systems.

Traditional food knowledge in a Matlatzinca community, Temascaltepec, State of Mexico
type: item
description: Food sovereignty relates to traditional food knowledge that makes food available through land cultivation, fishing, gathering and hunting. In the face of the loss of this knowledge, its preservation is necessary to conserve the traditional knowledge of the food systems through which biocultural diversity is preserved. The objective of this paper is to identify the food knowledge and culinary techniques of older adults in the community of San Francisco Oxtotilpan. Through an ethnographic retrospective approach using interviews, field diaries and photographs, from March to September 2022, the food memories of the elderly, from childhood to the present day, were recovered. The food knowledge (the consumption of quelites and edible insects and the hunting of wild animals) and the culinary techniques used to cook the foods that were part of the Matlatzinca community were identified and it was also observed how this gastronomic knowledge and these techniques have been modified. It is evident that there is a need to revalue the traditions and customs of the Matlatzinca people, as well as their gastronomy from a sociocultural perspective, as part of a process to preserve the community’s food and cultural identity, generating a sense of permanence.

Diagrammatic scale to assess the severity of Alternaria on sweet granadilla leaves
type: item
description: Alternaria on sweet granadilla is a foliar disease caused by a saprophytic fungus that poses a significant threat as it reduces the photosynthetic area and consequently affects the quality of the fruit. Nevertheless, there is no instrument available to facilitate the estimation of leaf severity in the field. In view of this, the objective of this research was to design and validate a diagrammatic scale that allows assessing the severity of Alternaria sp. on sweet granadilla (Passiflora ligularis Juss.) leaves. A diagrammatic scale was developed based on an inspection of 124 leaves. The proposal included seven levels of foliar severity (0%, 1%, 2%, 4%, 8%, 16% and 28%), established according to the Weber-Fechner Law. For validation, ten evaluators recorded the severity on 60 leaves first without using the scale, and then seven days later, using it. The results projected an average coefficient of determination (R2) of 0.639 in the first evaluation and 0.88 when applying the proposed scale. In addition, absolute errors decreased. In conclusion, this tool proved to be accurate and reproducible for quantifying the severity of Alternaria sp. on sweet granadilla leaves.

Optimal fertilization in rainfed corn regarding nutrient removal and soil diagnosis in small plots
type: item
description: In the south of the State of Mexico, Mexico, small corn producers obtain low yields (<5 Mg ha-1) due to deficiencies in nutrition management. The research aimed to determine the fertilization dose for small rainfed corn plots, considering the condition of soil fertility and nutrient extraction by grain and stover. The research was conducted in Villa de Allende, State of Mexico, in two plots with different fertilization management. Plot A received 1 t of bovine manure compost and plot B received 30 kg of a urea + triple 17 (N-P-K) mixture. Based on soil fertility diagnosis and nutrient removal by grain and stover, fertilization doses were defined. In both plots, OM and N contents were low and Fe levels were adequate. In plot A, the soil presented high levels of P, K, Ca and Mg. The grain and stover extracted high amounts of N and K. In plot A, the need for fertilizers was concentrated on N, Fe and Zn, whereas in plot B, it was N, P, K, Ca, Mg, Fe and Zn. This generated a reduction in the need for fertilizers; in the first case, it represented a 48% saving in costs. This approach contributes to improving productivity, reducing costs and reducing environmental impact in small-scale agriculture.

Viability and germination of Haematoxylum campechianum L. seeds as a function of temperature and storage period
type: item
description: Haematoxylum campechianum L., known as palo de Campeche or palo de tinte and as éek, tooso boon che’ or palo among the Mayans, has high commercial value and grows as a wild plant in the Yucatan Peninsula; this species is a taxon distributed in the region, with historical, patrimonial and economic value due to its commercialization as a raw material to extract natural dyes. The objectives of this research were to determine the morphometry, viability and germination of palo de tinte seeds in Campeche as a function of temperature and storage period in order to increase their forest use potential. Seeds were collected in the municipality of Escárcega, Campeche, in March 2024. Germination and viability (tetrazolium test) tests were performed every 30 days for eight months at different temperatures (-18 °C, 3 °C, 23 °C, and room temperature ≈ 31 °C). Significant differences (p< 0.05) were found in the percentage of germination (% G) as a function of storage time, where the highest percentage of germination (90%) was at the temperature of 3 °C. Viability was maintained for 180 days, then gradually decreased; based on the characteristics found, it is inferred that H. campechianum seeds are classified as intermediate.

Optimal strawberry distribution in Mexico (cycle 2023): a linear programming model
type: item
description: Strawberries are a strategic crop in Mexico due to their economic and social importance, with more than 640 000 t produced in 2023, concentrated in Michoacán, Guanajuato, and Baja California. Their high perishability requires efficient logistics systems. The study aimed to estimate the optimal strawberry distribution routes for the 2023 cycle, using a linear programming model that minimizes the total distance transported, comparing closed- and open-economy scenarios. To do this, linear programming was applied using the simplex method in Lingo 18.0, considering distance as a cost variable. In the first scenario (closed economy), 4 of the 16 producers concentrated 95% of the supply and supplied the 28 demanding destinations; in the second (open economy), a surplus of 158 000 t was exported, mainly via Mexicali, Tijuana, and Matamoros. The model allowed us to minimize the variable of travel distance; however, limitations were identified, such as the absence of monetary costs, seasonality and a lack of storage infrastructure. In conclusion, strengthening these areas will increase the competitiveness of the strawberry sector and improve national food security.

Granulometry and proximate analysis of flour from different organs of spring onion
type: item
description: The study was conducted from 2023 to 2024 in order to fully utilize spring onion (Allium cepa L.) due to its nutraceutical and functional value and the need to generate agro-industrial ingredients from plant byproducts. Flours were made from roots, bulbs and stem/leaves and they were subjected to proximate and granulometric analyses. The samples used were dehydrated at 38 °C by convection, and then ground to obtain the flours. Granulometry, moisture, ash, protein, lipids and carbohydrates were determined using official techniques. The results obtained showed significant differences (p< 0.05). Roots and stem/leaves showed the lowest lipid content (1-4.1%) and high fiber content (30.1% and 35.2%), respectively; bulbs presented the highest concentration of lipids (7.5%) and roots presented the highest amount of ash (11.4%). The three flours had a moisture content lower than the 7% required by Mexican regulations (0.7-5.2%). Therefore, the spring onion (Allium cepa L.) can be utilized in its entirety by producing added-value flours with applications in the food industry, thereby reducing the amount of residues obtained by reducing waste and generating an additional source of income for producers and self-sustaining value chains.

Physicochemical characterization of alternative substrates for ornamental plant production
type: item
description: In Mexico, the extraction of forest soil for the production of ornamental plants causes a negative ecological impact; this material represents the primary substrate used for the production of ornamental plants. This study aimed to characterize and validate different proportions of three raw materials obtained from waste and residues from other economic activities. To this end, various mixtures of garden waste (GW), pine sawdust (PS) and pine bark (PB) in different proportions, and a control substrate were physically characterized as potential substrate substitutes in ornamental plant production. Granulometry, bulk density, total and aeration porosity, water retention capacity, hydrogen potential (pH) and electrical conductivity (σ) were evaluated as main properties in the selection of substrates. The results of this study demonstrate the possible substitution of (unsustainable) forest soil with regional substrates of low production cost in the preparation of substrates for ornamental production. Substrates S3 (25GW+25PB+50PS), S4 (20GW+30PB+40PS), and S5 (50GW+25PB+25PS) are within the convenient ranges for plant production, based on their physical properties.

Selenium nanoparticles and selenite in lettuce seedling production
type: item
description: The production of quality seedlings in horticultural crops is a fundamental step for their success; to this end, fertilization plays a crucial role. Selenium (Se) has been evaluated for its beneficial effects on plant physiology. Nevertheless, studies at the seedling stage are scarce. Therefore, the present study was conducted at the Autonomous University of San Luis Potosí, Mexico, in 2025 with the aim of evaluating the foliar application of two selenium sources: sodium selenite (Na2SeO3) and Se nanoparticles (SeNPs), for the production of lettuce (Lactuca sativa L.) seedlings. The treatments were: 1) absolute control, 0 ppm Se (water spraying); 2) 1.5 ppm SeNPs; 3) 3 ppm SeNPs; 4) 4.5 ppm SeNPs; 5) 1.5 ppm Na2SeO3; 6) 3 ppm Na2SeO3; and 7) 4.5 ppm Na2SeO3. After 30 days of germination, dry weight, fresh weight, height, leaf area, shoot/root index, leaf area ratio, chlorophyll index, nitrogen balance index and flavonoid index were determined. The results indicated that foliar application of 3 and 4.5 ppm SeNPs improved the quality of lettuce seedlings, as they generated a better shoot/root balance, higher root dry weight, and a good nitrogen balance. These indicators suggest that seedlings may have more prolonged post-transplant survival and continuous growth, as they can have a greater capacity to absorb water and nutrients. No phytotoxic effects were found on seedling growth.

Immobilized nanomaterials for arsenic removal in agricultural systems: a brief review
type: item
description: Arsenic contamination in agricultural soils and irrigation water poses a significant threat to crop productivity and food security. In response to this problem, the present review aimed to analyze the use of immobilized nanomaterials as a technological alternative for the efficient removal of arsenic contamination in agricultural systems. Recent studies on the application of nanomaterials, such as zero-valent iron nanoparticles, nanoclays, and metal oxides, immobilized in polymeric, ceramic, or natural matrices, were collected and evaluated. The methodology consisted of a documentary and comparative analysis of scientific research published in peer-reviewed journals, considering the parameters of adsorption capacity, removal mechanisms, optimal conditions, and efficiency in the field. The results indicated that the immobilized nanomaterials have greater stability, regenerative capacity, and lower leaching risk compared to traditional methods. In addition, successful cases were documented in Mexico, where their implementation reduced the concentration of arsenic contamination in soils and irrigation water by up to 70%. It is concluded that the use of immobilized nanomaterials is a viable and sustainable strategy for agricultural decontamination; nevertheless, more studies on their environmental impact and cost-benefit are still required for their large-scale application.
