Advances in cowpea cropping systems research por Olufajo, O.O., Singh, B.B.

“…These include improved productivity as a result of early cowpea planting, strip cropping, dense planting, and appropriate soil fertility management. For example, in West Africa, the use of high yielding improved varieties in a strip cropping system with two cereal rows : four cowpea rows offers an opportunity for selective input application and appears to be economically superior to the traditional one cereal row: one cowepea row.…”
