Effect of potash levels and apportioning time on yield and economic of summer groundnut under drip irrigation

Abstract

A field experiment on Effect of potash levels and apportioning time on yield and economic of summer groundnut under drip irrigation was carried out at All India Co-ordinated Research Project on Summer Groundnut, M.P.K.V., Rahuri. The pod and hualm yield were significantly increased under groundnut crop grown with potash level 30 kg K2O ha-1 as compared to other potash levels. The dry pod yield kg ha1, kernel yield kg ha-1 and dry haulm yield kg ha-1 were significantly increased in potash apportioning time at 75 DAS with 10 splits. The potash level 30 kg K2O ha-1 significantly increased gross and net monetary returns as compared to other potash levels. The gross monetary returns (Rs. 171807 ha-1), net monetary returns (Rs. 110793 ha-1) and B:C ratio (2.82) were recorded with 30 kg K2O ha-1. Treatment K3 i.e. 30 kg K2O ha-1 yielded better results than other potash levels. The gross (Rs. 157135 ha-1) and net monetary returns (Rs. 95985 ha-1) and B:C ratio (2.57) were significantly more at potash apportioning time 75 DAS with 10 splits followed by potash apportioning time at 60 DAS with 8 splits.
