1. Study the "rotational effect" in sorghum-soybean and millet-soybean rotations by evaluating: I. nitrogen and of legumes and 2. soil moisture relationships b 2. Long-term studies to determine sorghum/peanut and mil-let/cowpea cropping systems (monoculture, rotation, intercropping) by nitrogen fertilizer rate interaction effects will be continued in Mali.Reutofheyedosobasflwigorumvr 3. Long-term studies to determine sorghum genotype (tall, intermediate, short) by residue management interaction ef- fects will be continued in Mali. 4. Evaluate the nitrogen by water interaction on yield of sorghum hybrids and local cultivars.
