Field experiment was carried out in Dalwa, Maiduguri to investigate the effects of intercropping pattern and planting date on the performance of two cowpea varieties with sorghum. The experiment was laid in split-plot design each replicated three times including control. The factorial experiment consisted of two varieties of cowpea (Borno brown and Banjiram), two planting dates (early and late planting) and three intercrop patterns (1:1, 1:2 and 1:3). The results showed that cowpea flower count per plant were significantly higher (p<0.05) in Borno brown cowpea variety, late planting and 1:1 intercrop pattern. It further showed that cowpea pods count per plant was significantly higher in varieties, early planting date and 1:1 intercrop pattern. Grain yields were significantly higher in both varieties and not significantly different from one another, but higher in early planting date and higher in 1:1 and 1:2 intercrop patterns. Farmers in the Maiduguri Northern eastern region of Nigeria could therefore adopt early planting of the two varieties at 1:1 and 1:2 intercrop patterns.
