Adoption and ex-post impacts of improved cowpea varieties on productivity and net returns in Nigeria
An assessment of the adoption and impacts of improved cowpea varieties on yields, net returns, and production costs in northern Nigeria, using data from 1,525 households and applying a control function approach and propensity score matching models.
Effects of plant density on the performance of cowpea in Nigerian savannas
This study presents the results of field experiments in Nigeria to establish optimum plant densities of cowpea.
Agronomic response of soybean varieties to plant population in the Guinea Savannas of Nigeria
This study examined the agronomic responses of three contrasting soybean [Glycine max (L.) Merr.] varieties to plant populations in two distinct agro‐ecological locations (at Samaru Zaria and Samaru‐Kataf) within the Guinea savanna region of northern Nigeria in the 2009, 2010, and 2011 growing seasons.
Response of old and new cowpea varieties to insecticide spray regimes in the Sudan Savanna of Nigeria
This paper determines the response to insecticide spraying of old cowpea varieties developed in the late 1970s and new varieties developed in the 2000s – in order to determine whether the new varieties have less requirement for spraying.
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.
