A field study was conducted to determine the rate of genetic improvement in grain and fodder yields of cowpea genotypes developed in the Nigerian Sudan savannas from 1970 to 2004. Results showed that grain yield ranged from 568 kg/ha for an old variety TVX3236 to 1851 kg/ha for a recently release...
Recent surge in dry cowpea seed price, grain and fodder demand in Niger Republic has resulted in the search for appropriate cultivars for dry season production for seed, grain, and fodder. However in addition to the common constraints to cowpea production in the wet season, high temperature in th...
Food needs arising from the demographic explosion of sub-Saharan Africa can only be met through agricultural intensification. Smallholder systems feature enormous yield gaps, which may be reduced through ISFM and other sustainable intensification practices. However, today’s huge variability in f...
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 ...
