This study has investigated the interactions between host cultivar, strain of Rhizobium and inorganic nitrogen on vegetative growth, seed yield and carbon and nitrogen nutrition of cowpea cultivars bred for their seed production. Differences between and within cultivars inoculated with either the same or different strains of Rhizobium were recorded for most vegetative and reproductive components. Some symbiotic combinations improved vegetative growth but not seed yields. Applying 20 ppm inorganic nitrogen daily throughout the vegetative period overcame the nitrogen-hunger syndrome characteristics of many nodule-dependent legumes. Seed yields were also improved and were similar to those of plants which received 20 ppm N daily throughout crop duration. Inorganicnitrogen applied only throughout the reproductive period did not overcome the limitations to yield consequent upon a slow rate of early vegetative growth. With more productive cultivar-Rhizobium combinations, a daily supply of inorganic nitrogen throughout growth promoted vegetative development but reduced seed yields. Current symbiotic fixation was the major source of nitrogen to fruits. When symbiotic fixation and carbon assimilation were suppressed at mid pod-fill, by either shading or defoliation, plants could not compensate by increased mobilization of reserves and seed yields were drastically reduced. Plants grown in either close-to-optimum or adverse environmental conditions gained most of their dry matter, carbon and nitrogen within a 20 day period...
