Abstract

A field experiment was conducted during the kharif seasons of 2019-20 and 2020-21 to study the influence of tillage practices, nutrient levels and foliar sprays on nutrient content of redgram [Cajanus cajan (L.)] on sandy loam soil which was low in available nitrogen, medium in available phosphorus and available potassium. The experiment was conducted in a split-split plot design, consisting of three tillage practices in main plots, three nutrient doses in sub-plots and three foliar sprays in sub-sub plots. Higher nutrient content of redgram was recorded with vertical tillage with subsoiler upto 60 cm deep at 1 m interval with application of 125 % RDF along with foliar application of KNO3 1 % twice with 15 days interval from 50 per cent flowering stage.
