Genetic gain in yield and agronomic characteristics of cowpea cultivars developed in the Sudan Savannas of Nigeria over the past three decades
This paper evaluates a field study conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semi-determinate cowpea genotypes developed in the Nigerian Sudan savannas from 1974 to 2004.
Phosphorus and Nitrogen fertilization of soybean in the Nigerian Savanna
The objective of this research was to determine the interactive effect of N and P on soybean productivity in the northern Guinea and Sudan savannas of northeast Nigeria. The results suggest that N fertilizer is not critical for soybean production in this area.

Improvement in grain and fodder yields of cowpea genotypes representing four decades of breeding in the Nigerian Sudan savannas
This paper presents the findings of a field study conducted to determine the rate of genetic improvement in the grain and fodder yields of cowpea genotypes developed in the Nigerian Sudan savannas from 1970 to 2004.
Lessons from Two Years of Tropical Legumes II: Second Annual Review and Planning Meeting 16–20 November 2009, Bamako, Mali
Lessons from two years of the Tropical Legumes II Project, funded by the Bill & Melinda Gates Foundation (BMGF), which aims to bring about significant increases in the productivity and production of tropical legumes to improve farmers’ income, nutrition quality, and livelihoods in the drought-prone areas of SSA and South SA.
