Abstract

The objective was to evaluate the grasses of the genus Urochloa: Mulato II, Convert 330 and Convert 431 by varying the cut ages in the attributes: stem population dynamics, tissue replacement, leaf:stem ratio, weight per stem and dry matter yield. The research was carried out in the grasslands of the Technological Institute of Pinotepa, in the locality of San José Estancia Grande, Oaxaca. The treatments were the genotypes: Mulato II, Convert 330 and Convert 431. The data were analyzed using a completely randomized block design arranged in split plots and four repetitions, the procedure used was PROC GLM of SAS. The Mulato II grass had the highest stem density with an average of 540 stems m-2, while the Convert 330 grass had the lowest stem density throughout the research, with an average of 220 stems m-2, tending to increase slower over time (p< 0.05). The grass that obtained the highest net growth was Convert 330, followed by Mulato II and, at the end, Convert 431, with an average of 169, 133 and 104 cm stem-1, respectively (p< 0.05). On day 49 after cutting, the Convert 330 grass obtained the highest yield with 4 091 kg DM ha-1 (p< 0.05). In conclusion, the Convert 330 genotype showed better structural characteristics in the grassland, which reflects a higher dry matter yield.
