This project focused on determining the water use efficiency of grain sorghum and pearl millet following soybeans in rotation. Study the ”rotational effect” in grain sorghum-soybeans and millet-soybean rotations by evaluating: (a) nitrogen contribution of legumes, (b) soil microbial populations,(c) soil physical and chemical properties, and (d) soil moisture relationships. At present isolines of non-nodulating and nodulating soybean have been incorporated into the study. Evaluate the nitrogen contribution of intercropped cowpeas harvested for forage and grain to pearl millet.
