Consorciação de trigo de duplo propósito e cornichão na fronteira oeste do Rio Grande do Sul

Abstract

Wheat (Triticum aestivum L.) has great ability to tiller emission, as a result, dualpurpose cultivars, such as BRS Tarumã produce forage and still achieve good grain yield at harvest. Intercropping of this grass with a legume can bring various benefits such as reduced costs of deployment pasture. Therefore, the aim of this study was to evaluate the performance of dual-purpose wheat and birdsfoot trefoil in consortium regarding growth and dry matter production in response to the frequency and intensity of defoliation. The experimental design was a randomized block with three replicates, and treatments outlined in a 2x2 factorial arrangement where we studied the effect of cuts (one and two) and residue heights (5 and 10 cm). The wheat produced greater herbage accumulation with doing two cuts, which produced 2512.00 kg ha-¹ DM significant difference when compared to production of a single cut that was 860.86 kg ha-¹ DM. With respect to the consortium, the highest production was 2555.83 kg ha-¹ of DM with two cuts. The DM yield of birdsfoot subsequent evaluations at the end of the crop cycle of wheat showed no significant difference. It was concluded that wheat and produce more forage when birdsfoot made two cuts in her period of vegetative growth. And the management of courts at different times had no effect on the production of wheat in the consortium, the consortium of birdsfoot trefoil and after the end of the crop cycle of wheat
