Sg. Sadaria et al., IRRIGATION AND FERTILIZER MANAGEMENT IN ONION (ALLIUM-CEPA) AND ITS RESIDUAL EFFECT ON GROUNDNUT (ARACHIS-HYPOGAEA), Indian Journal of Agronomy, 42(4), 1997, pp. 709-712
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.
