Abstract
A field investigation was conducted during two consecutive kharif seasons of 2019-20 and 2020-21 to study the effect of tillage, nutrient levels and foliar sprays on yield and nutrient uptake of redgram on sandy loam soil which was low in available nitrogen, medium in available phosphorus and available potassium. The research was conducted in a split-split plot design, consisting of three tillage practices in main plots, three nutrient levels in sub-plots and three foliar sprays in sub-sub plots. Higher seed yield and nutrient uptake of redgram was recorded with vertical tillage with subsoiler upto 60 cm deep at 1 m interval with application of 125 % RDF and with foliar application of KNO3 1 % twice with 15 days interval at 50 per cent flowering stage.
