- Abstract
Consortium between maize crop and forage species managed with herbicide reduce doses have been widely used in the crop integration system for pasture formation. However, answers to this management in both maize and forage have presented different responses. In this research, evaluated the corn productivity, weed population dynamics, and yield and quality characteristics of pasture the Urochloa brizantha in three cuts when it was formed after the harvest of corn treated with tembotrione subdoses. The subdoses tested were: 0; 3.78; 7.56; 15.12 e 22.68 g ha-1. Corn and forage were also tested in monocultures. In a consortium, weed species Alternanthera tenella, Commelina benghalensis and Galinsoga parviflora were of relative importance (IR) and were not controlled by the herbicide. Yield of maize grains was not affected by forage, but forage yield (YF) of grass was reduced by maize. The tembotrione subdoses affected YF both in maize intercropped pastures and in pasture formed during the rainy season. The values of ethereal extract and crude protein in the pasture formed were influenced by the herbicide management.
