Abstract
A field experiment conducted at Junagadh (Gujarat) during 1991-92 to 1 993-94 revealed that irrigation at 1.4 IW : CPE significantly increase d bulb yield of onion (Allium cepa L.) with higher net return and upta ke of N and P, while that at 1.2 IW : CPE recorded the highest water-u se efficiency (WUE). A dose of 75 kg N/ha emerged out to be the optimu m dose for bulb yield, net return, WUE and uptake of N and P. Phosphor us fertilization did not influence bulb yield and nutrient uptake; how ever higher net return and WUE were recorded with application of 37.5 kg P2O5/ha. Irrigation, nitrogen and phosphorus applied to preceding o nion crop did not show their residual effect on pod yield and uptake o f N and P by groundnut (Archis hypogaea L.) grown in succeeding (khari f) seasons.
