ABSTRACT

A field experiment was conducted during two consecutive kharif seasons of 2019-20 and 2020-21 to study the influence of tillage, nutrient levels and foliar sprays on post-harvest soil available micro nutrient status of redgram 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 as main plots, three nutrient levels in sub plots and three foliar sprays in sub- sub plots. Tillage, nutrient and foliar sprays could not exerted significant influence on post-harvest soil available micronutrient status. But higher soil available micronutrient content was recorded with vertical tillage with subsoiler upto 60 cm deep at 1 m interval with application of 125% RDF and foliar application of KNO3 @ 1% twice with 15 days interval from 50 per cent flowering stage.
