No-tillage and crop rotations for regions with water deficit

Objective
To understand the contribution of leguminous green manure for corn yield
Description
four treatments (corn, soybean, sun-hemp or mucuna and a mix of crops: sweet sorghum, sunflower, soybean and biomass sorghum) is cultivated during three years. After planting those crops during three years, corn is planted in each plots with different nitrogen rates. This trial is like on farm research (big and mechanised plots)

Randomized complete block design
Description
In randomised block experimental design, four treatments (corn, soybean, sun-hemp or mucuna and a mix of crops: sweet sorghum, sunflower, soybean and biomass sorghum) is cultivated during three years. After planting those crops during three years, corn is planted in each plots with different nitrogen rates. This trial is like on farm research (big and mechanized plots).
