Productivity, profitability and sulphur status in soil after harvest of crop as affected by different sulphur levels and application methods

Abstract

An experiment was carried out at Agronomy farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner during rabi, 2019-20 to find out the response of chickpea (Cicer arietinum L.) to different sulphur levels and application methods under irrigated conditions of Rajasthan”. The experiment was laid out in split plot design with three replications assigning four levels of basal application of sulphur (0, 20, 40 and 60 kg ha-1) in main plots and four concentrations of foliar spray of liquid sulphur (0, 0.1, 0.2 and 0.3% sulphur) at 65 and 75 DAS in sub plots. The findings indicate that basal sulphur applications of 40 kg ha-1 had significant effects on seed and straw yield, available sulphur in soil, net return as well as B:C ratio over control and basal sulphur applications at 20 kg ha-1, which was being at par with basal sulphur applications at 60 kg ha-1. The seed and straw yield, net return as well as B:C ratio significantly increased with foliar spray of liquid sulphur (0.2%) over control and foliar spray of liquid sulphur (0.1%), which was being at par with foliar spray of liquid sulphur (0.3%).
