Germplasm enhancement for increasing groundnut productivity and production in West and Central Africa
This conference paper discusses current efforts to deploy modern breeding approaches and tools to enhance genetic gains and support national groundnut breeding programs in West and Central Africa.
Variability in yield and vegetative growth of some selected cowpea [Vigna unguiculata (L.) Walp.] lines under varying shade conditions
This study was conducted to elucidate the effect of varying shade conditions of some selected cowpea lines in relation to their vegetative growth and yield. The study revealed positive phenotypic correlation coefficients of higher magnitudes for varieties grown under the single and double shading conditions.
Selection of intermittent drought tolerant lines across years and locations in the reference collection of groundnut
The results presented in this paper show a close interaction between environmental conditions and the genotypic response to intermittent drought, suggesting the need to carefully choose environments that truly represent target environments.
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.
