Produtividade de trigo forrageiro ( Triticum aestivum L.) Cultivar MGS brilhante em diferentes densidades populacionais no município de Bambuí - MG

Abstract

Forage wheat has stood out as an alternative for forage production during the winter period, especially in regions of the Brazilian Cerrado, due to its adaptation to water deficit and its nutritional value. The appropriate choice of sowing density is an important factor for crop establishment and for achieving satisfactory productive results. Thus, this study aimed to evaluate the performance of the forage wheat cultivar MGS Brilhante subjected to different sowing densities in the municipality of Bambuí - MG. The experiment was conducted in a randomized block design, with four treatments and five replications, using densities of 300, 400, 500, and 600 seeds per m2. The evaluated variables were plant height, green matter, dry matter weight, number of leaves, number of tillers, number of spikelets, and spikelet length. The data were subjected to analysis of variance and, when significant by the F test, to regression analysis. Significant differences were observed for plant height and number of spikelets. Plant height showed a quadratic behavior, while the number of spikelets showed a linear reduction with increasing plant population density. For green matter weight, dry matter weight, number of leaves, number of tillers, and spikelet length, no significant differences were observed among treatments. The increase in plant population also did not result in a significant increase in green matter and dry matter production. Therefore, under the evaluated conditions, the density of 300 seeds per m2 showed the most satisfactory performance among the variables that demonstrated significant differences, and it is not possible to state statistical superiority for all analyzed variables.
