PRODUÇÃO DE GRÃOS E SILAGEM DE GIRASSOL CONSORCIADO COM DIFERENTES FORRAGEIRAS

Abstract

One of the most used production strategies nowadays is the Integration Lavoura Pecuária (ILP) system, aiming at diversity within a rural property. This system is capable of providing benefits, such as greater grain production combined with the sustainability provided by intercropping with forage, and may give the option of a third crop through the pasture formed in the off-season. This system allows better use of the area, soil decompression, reduction of diseases by crop rotation, nutrient cycling, among other benefits. Sunflower is an option in the second harvest, being an economically profitable crop, as it is resistant to water stress, a common situation in this period in the Midwest region of Brazil. In this scenario, sunflower can be intercropped with tropical forages. The experiment was developed to evaluate the behavior and productivity of sunflower intercropped with tropical forages (Megathyrsus maximus cvs. BRS Zuri and BRS Tamani and Urochloa ruziziensis). The results demonstrate that the consortium between sunflower and forage reduced the productive potential of sunflower. The sunflower consortium with Zuri proved to be a viable alternative for silage production in the second harvest and the consortium with BRS Tamani proved to be the most sensitive to climate variations resulting from the second harvest.
