Four double cropping systems for year-round culture (maize, sorghum-rye, barley) using a combined machine consisting of harvester, fertilizer distributor and seeder were evaluated. The 4 systems obtained over 0.25 t/acre and had a higher yield than the usual systems of double cropping and single cropping.
