After 25 years of no-till system adoption in the subtropical humid region of Brazil, crop failures have been frequent due to moisture stress induced by rainfall shortage. This problem is associated to degraded soil structure as result of lack of adoption of Conservation Agriculture principles, mainly poor crop rotation with plant biomass production below the soil biological demand. In this region of the country, this aspect is evident in the 14 million hectares of summer growing area, of which only 2.6 million hectares are cultivated during the winter. While the winter grain production has suffered from market limitations, the crop-livestock system has the economical potential to promote intensification and diversification of production models. At the same time that there is market for animal products, there is a shortage of pasture between summer and fall cropping seasons. The present study aims at evaluate the feasibility of maize-Brachiaria spp. (Urochloa spp.) intercropping system in the grain and pasture production models, that allow two or three crops per year, in a specific land area. This study was carried out in the experimental area of Embrapa Trigo, in Coxilha, RS, with single maize and maize intercropped with brachiaria as treatments, under randomized complete block design – RCBD with four replicates, during the 2005/2006 to the 2009/2010 cropping seasons. The trial was established, every season in the beginning of spring season. Maize grain yield and brachiaria forage dry matter were determined from the end of January to beginning of February. Intercropping brachiaria did not affect the maize yield, independent, of rainfall distribution during the cropping seasons. The maize-brachiaria intercropping system allows the adoption of the harvesting-seeding process that reduces the time period between summer and fall cropping seasons. Therefore, the brachiaria pasture becomes the second crop in the summer season and the third crop in a single year.
