Grain yields of cowpea [Vigna unguiculata (L.) Walp.] in the Nigerian savannas are low even with the cultivation of improved varieties. The recommended spacing for cowpea is 75 × 20 cm with two seeds planted per stand. This corresponds to plant population of 133333 plants ha−1, which may not be s...

Spatial arrangement of crops is critical in determining the growth and yield of lower crops in intercropping. The productivity of two spatial arrangements of pearl millet-groundnut intercrops was studied in the Sudan savanna of Nigeria during 2014 rainy season at Wasai (5ˈN, 08o62ˈE) in Minjibir ...

Soybean (Glycine max) is a major cash crop in the savannas of Nigeria although productivity is typically constrained by poor soil fertility. 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 north...

Field trials were conducted in 2005 and 2006 in Tilla (northern Guinea savanna) and Sabon-Gari (Sudan savanna) in northeast Nigeria to determine the performance of two improved cowpea varieties when relay-intercropped with early and late maize, 6 and 8 weeks after planting the maize. Grain yield,...

Identification of the best variety from a variety trial is often done using the least significant difference (LSD), Duncan’s multiple range test (DMRT) and stability analysis methods. However, these methods are unable to discriminate among a smaller group of varieties which are not statistically ...

Cowpeas suffer major yield losses due to insect pests, so insect resistant cowpea varieties are being developed to minimize insecticide use in integrated pest management. Experiments during the cropping seasons of 2002–2004 at Kano, Nigeria, evaluated four cowpea varieties and five combinations o...

Breeding for resistance to Striga can be done effectively under high and uniform artificial field infestation. To identify Striga tolerantresistant maize genotypes, it is essential to artificially inoculate every hill of maize in the breeding nursery with Striga seeds. The present method of inocu...
