Effect of weed management and sulphur fertilization on nutrient content and nutrient uptake by Mustard (Brassica juncea (L.) Czern & Coss) under semi arid condition of Rajasthan

Abstract

A field experiment was conducted during rabi 2014-15 and 2015-16 at Agronomy farm, Jobner, Rajasthan to evaluate effect of weed management practices and sulphur fertilization on Nutrient content and nutrient uptake of mustard (Brassica juncea (L.) Czern & Coss). The result indicated that among weed management practices, the highest seed & Biological yield (2493 kg/ha & 9628 kg/ha) were obtained with two HW treatment which was significant rest over the treatment. Two HW treatment and pendimethalin @ 0.75 kg/ha (PE) were found significantly better treatments in enhancing N, P & S concentration in Seed and straw as well as their uptake, protein content in seed. Application of Sulphur at 60 kg/ha in mustard improved the nutrient concentration in seed, Straw and their uptake by crop.
