Influência de cortes na produtividade e nas características bromatológicas do trigo de duplo-propósito

Abstract

The objective of the work is to evaluate the bromatological quality and productivity of dual-purpose wheat under different cutting regimes. For the experiment, three treatments were used that deal more with cutting management, which are: 1 - no cutting; 2 - a cut and; 3 - two cuts; using 5 repetitions for each treatment. This research was carried out in a greenhouse, and with the Embrapa BRS Pastoreio cultivar. Several results can be observed in relation to the bromatology and production of dual-purpose wheat crops. The variables evaluated were in two stages, first the bromatological one, which included dry matter, ether extract, crude protein, NDF, FDA, hemicellulose content and mineral matter. The second part was related to production, in which grain production per hectare, thousand grain weight, residual dry biomass, total dry biomass, number of tillers, tiller height, ear size and number of grains per ear were evaluated. It is a crop that presents a good amount of green matter and dry matter, aiming at good quality nutrition for grazing cattle. Furthermore, it showed a high capacity for productivity and grain yield, making it very worthwhile to be cultivated by rural producers who have grazing animals.
