Abstract

The amaranth is a potential crop that is gaining importance in Mexico, because every day there is more demand. This crop is grown under conventional tillage systems and transplant, recently opening up new areas of cultivation used in irrigation and mechanical harvesting. The technology package for the production of amaranth is not fully defined, so that in order to determine the effects of the locality, fertilization, plant density and varieties, the present experiment was established. The experiment was performed in a randomized complete block design with three replicates randomly in the towns of San Miguel del Milagro Montecillo Tlaxcala and Mexico State, three doses (0, 60 and 80 kg ha-1) of N combined with two (30 and 60 kg ha-1) P dose, plant densities of 100 000, 150 000 and 250 000 plants ha-1 and DGTA varieties, Gabriela and Revancha belonging to A. hypochondriacus. The results show that, the locality, fertilization, plant density and plant density interaction∗variety had significant effects on seed yield. The highest yield corresponded to the town of Montecillo, Estado de Mexico, a 80-60-40 and 80-30-40 formulas with a 668.7 and 1 660.9 kg ha-1, respectively, to the variety DGTA (1 778.2 kg ha-1) and plant density of 100 000 plants ha-1. For the plant height, the variety and plant density had significant effects, being the Revancha variety the one that presented a plant height suitable for mechanical harvesting in the three plant densities. In relation to lodging, only fertilization had any effect, resulting in the formula 60-60-40, 60-30-40 and 80-60-40 with percentages of 37.21, 36.98 and 35.9, respectively.
