Abstract
To determine the chemical composition of intercropping and monoculture cultivars of sorghum, millet and midget-guandu, we determined the production of dry matter (DM), ashes, gross fiber, ethereal extract, gross protein (GP), nutritious digestive total, and extractive without oxygen. The experimental design used was completely random blocks with four repetitions split into 18 treatments: monoculture sorghum, monoculture midget-guandu, monoculture millet, intercropping sorghum and midget-guandu, millet and midget-guandu and millet and sorghum, with cutting times at 30, 60 and 90 days after sowing (DAS). Millet had the highest production of dry biomass at 30 and 60 DAS in monoculture and intercropping. The highest DM was obtained by intercropping (90 DAS). Sorghum intercropping had the highest crude protein at 30 DAS, and the midget-guandu promoted increased crude protein at intercropping.
Highlights
No-tillage (NT) systems have begun to be adopted in various regions in Brazil, but with little knowledge of the cover crops that are able to produce the amount of dry matter (DM) sufficient for the system and to maintain or increase the soil fertility and productivity of crops
At 90 days, the millet+sorghum ratio was reduced, though the millet remained as the main constituent responsible for total DM production in the three periods evaluated
Andreola et al (2000) and Perin et al (2004) stated that in grass and legume intercropping the grass contributes to relatively high amounts of biomass, which are characterized by a high C/N ratio and which increase the persistence of land cover over time
Summary
No-tillage (NT) systems have begun to be adopted in various regions in Brazil, but with little knowledge of the cover crops that are able to produce the amount of dry matter (DM) sufficient for the system and to maintain or increase the soil fertility and productivity of crops. The contribution is made indirectly by the transfer of fixed N to grass, which increases the carrying capacity of pasture and extends its productive capacity (VIERA VARGAS et al, 1995). Another advantage of legumes is their lower seasonal
