Tied-ridge techniques have not been used to improve seed yield in cowpeas, so experiments were conducted in Burkina Faso in the Sudan savannah zone on an Alfisol at five slope-positions on the toposequence, using two dates of planting for three consecutive years; and in the northern Guinea savann...

Effects of seedbed preparation methods on cowpea yield in Alfisols and Oxisols in semiarid West Africa
Two sets of experiments on cowpea sowing date were conducted in 1983–85 at Ouagadougou, Burkina Faso. One set tested six daylength-insensitive (DI) cultivars and the other compared four or five daylength-sensitive (DS) cultivars with one or two DI cultivars as controls. Sowing after inadequate ra...

Use of successional sowing in evaluating cowpea (Vigna unguiculata) adaptation to drought in the Sudan savannah zone. 2. Responseof reproductive traits
The results of this study indicated that this procedure is sufficiently sensitive to reflect the effects of tillage, residue cover and crusting on infiltration data. Raindrop impact reduced infiltration rates by crusting the soil surface. However, most of the management systems that left about 30...
