The cerrados of Maranhão have stood out in grain production during the rainy season. However, the agricultural areas remain idle after grain harvest until the end of the dry season. An alternative for diversifying and intensifying the use of these areas is the crop-livestock integration system (CLI). The strategy used in this work consisted of evaluating a representative farm in the region in which the land use history was partly based on monoculture using soil tillage with disc harrows, and partly based on no-tillage seeding on a millet mulch. The prevailing activities in the farm were soybean - with an average crop yield of 47 bags (60 kg)/ha, corn - with an average crop yield of 132 bags (60 kg)/ha, and a small area dedicated to cattle production. This work aimed at assessing and validating an integrated production system under real conditions over time. It aimed also to introduce and disseminate the crop-livestock integration system in the cerrados of Maranhão

The Cerrado of Maranhão has stood out in the production of grains in cropland areas. Although intensely managed during the cropping cycle, these areas remain idle or underutilized for longer periods in the dry season. An alternative for the more efficient use of these areas is the use of integrated crop-livestock systems. This system is characterized by diversification, rotation, intercropping and / or succession of agricultural and livestock activities within the farm, resulting in a single system with mutual benefits. This study aimed to evaluate the production of young cattle in an integrated crop-livestock system in Maranhão, during the dry season.

Resumo: The soybean has been widely used within integrated systems, especially in the first stages of development of forestry species when competition for resources such as light, water and nutrients are lesser. Being able to timely cultivate legumes within an integrated system is of ultimate importance since soil characteristics, both physical and chemical, are concurrently improved with income generation.

O teor de fibra e digestibilidade in vitro da material seca (DIVMS) das forrageiras são variáveis de grande interferência na produção animal e podem ser influenciados pelo nível de sombreamento do sistema. O objetivo com este trabalho foi avaliar teor de fibra e digestibilidade do capim Marandu (Brachiaria brizantha cv. Marandu) em sistema silvipastoril. O delineamento foi inteiramente casualizado, em parcela subdividida, com quatro repetições. Os teores de FDN e FDA foram maiores no outono (63,4% e 30,8%) e menores para inverno e verão (59,0 e 27%). A DIVMS foi afetada pela interação estações do ano x face de exposição do renque de Eucalipto (P<0,05). Na face norte a digestibilidade foi maior para verão e outono (77,2%) e menor para inverno (75,3%). A face sul apresentou maior digestibilidade no verão (81%), e valor intermediário no outono (77%) com menor valor no inverno (71%). O teor de fibra e digestibilidade da forragem de capim Marandu em sistemas silvipastoris com renques espaçados de 30 metros e com árvores de até 9 metros varia em função da distância do renque, face de exposição e estação do ano.
