Effect of integrated nitrogen management on the yield, quality and economics of mustard (Brassica juncea L.)

Abstract

A field experiment was conducted during the rabi season of 2017 on mustard crop (var. DHARA) at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Allahabad (U.P.).To study the effect of integrated nitrogen management on growth and yield of mustard. The experiment consisted of providing 80 kg nitrogen to mustard by supplying 50 kg nitrogen through urea and 30 kg nitrogen either through poultry manure or by farmyard manure or by vermicompost with and without Azotobacter seed inoculation, which was compared with 80 kg nitrogen supplied through urea alone. Hence, comprising of seven treatments, which were laid out in Randomized Block Design and replicated thrice. The result showed that application of 50 kg nitrogen through urea + 30 kg nitrogen through poultry manure+ Azotobacter (seed inoculation) gave higher yield attributes and quality viz., seed yield (2.37 t ha -1), stalk yield (6.62 t ha -1), harvest index (26.35) and oil content (39.30%). The higher gross returns (
