- Abstract
SUMMARY Effectively nodulated cowpea plants were grown to reproductive maturity in growth cabinets set to simulate factorial combinations of daylength (11 h 40 min or 13 h 20 min), day temperature (27 or 33°C) and night temperature (19 or 24°C) characteristic of humid tropical environments. The experiment was designed specifically to compare and contrast the growth, reproductive ontogeny and seed yield of these plants with data obtained earlier when the same symbiotic combination (cv. K 2809 and Rhizobium CB 756) received large amounts (197 mg/l) of inorganic nitrogen throughout growth. These comparisons have shown that effectively nodulated plants are potentially no less adaptable to the aerial environment than are plants depending on inorganic nitrogen, whilst producing equally as good, or even better, seed yields.
