Abstract

In a field experiment on sandy-loam soil during the rainy seasons of 1988-90 at Sriganganagar, Rajasthan, groundnuts cv. RSB 87 were irrigated at various combinations of vegetative, flowering, pegging and pod-development growth stages and given 0, 30 or 60 kg P2O5/ha. Irrigating at all the 4 growth stages gave the highest mean pod yield of 1.60 t/ha. Pod yield and seed oil content increased with increasing P rate. Application of 60 kg P2O5 resulted in significantly higher pod yield than 0 and 30 kg P2O5/ha. The consumptive use of water increased with increasing frequency of irrigation. Consumptive use of water, water-use efficiency, and P uptake were highest with 4 irrigations. Increasing application of P increased consumptive use, water-use efficiency, and uptake of P
