Abstract

Five cultivars of cowpea (Vigna unguiculata (L). Walp.) were compared as intercrops of sugarcane during the 1981/82 spring planting season. Différences in flowering rate of cultivars between season were noted. At populations of 57,000 plants ha1, seed yields ranged from 162 Kg/ha (VITA 3) to 448 Kg/ha (Laura Β). Shelling percentages and the number of pods/plant, significantly affected yields of all cultivars. Number of tillers in the Laura B plots at 81 days were significantly higher than other cultivars. However, the heights of tillers in both Laura B and TVX 1850-01E plots were demonstrably shorter. Although nitrogen levels of the soil, following intercropping were appreciably increased, no significant différences in other soil chemical properties were observed.
