Response of different phosphorus, sulphur and zinc levels on yield and economics of lentil cultivation in sub-humid region of Rajasthan

Abstract

The experiment was conducted during rabi season of 2020-21 and 2021-22 at the Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan). The experiment consisted of 18 treatments comprising different levels of phosphorus (three- 30,40 and 50 kg P2O5 ha-1), sulphur (three- 15, 20 and 25 kg S ha-1) and zinc (two- control and 0.5 % ZnSO4). The experiment was laid out in factorial randomized block design (FRBD) and replicated thrice. The results revealed that application of 50 kg P2O5 ha-1 recorded significantly higher biological yield, seed and haulm yield, net returns and benefit cost ratio. Among sulphur levels seed and haulm yield, biological yield, net returns and benefit cost ratio were higher under application of 25 kg S ha-1 and same results were found with foliar spray of 0.5 % ZnSO4 at 55 days after sowing. Thus, it can be concluded that application of 50 kg P2O5 ha-1 with 25 kg S ha-1 and 0.5 % ZnSO4 foliar spray at 55 DAS in lentil is productive as well as profitable.
