Improving cowpea cereals based cropping systems in the dry savannas of West Africa por Singh, B.B., Ajeigbe, Hakeem A.

“…We evaluated four cereal-cowpea intercropping row arrangements involving one cereal: one cowpea, one cereal : four cowpea, two cereal : four cowpea intercrops, and sole crops of improved and local varieties of millet, cowpea, and sorghum with selective application of two sprays of insecticides on cowpea only and 100 kg/ha fertilizer (N.P.K. 15: 15: 15) basal and 20 kgN/ha top-dressed to cereals only. The results indicated sole crop improved cowpea to be most profitable followed by the two cereal: four cowpea intercrop system. …”
