Interaction effect of varying level of nitrogen and sulphur fertilizers on growth and yield of Indian mustard (Brassica juncea L.) under Northern hill zone of Chhattisgarh

Abstract

The field experiment entitled “Interaction effect of varying level of nitrogen and sulphur fertilizers on growth and yield of Indian mustard (Brassica juncea L.) under Northern hill zone of Chhattisgarh.” was conducted during the rabi season of 2019-20 at Research farm of Ambikapur (CG). The field experiment was conducted in factorial randomized completely block design constituted of sixteen treatment combinations consisting four levels of nitrogen fertilizer (30, 60, 90 and 120 kg ha-1) and four levels of sulphur fertilizer (0, 20, 30 and 40 kg ha-1) and replicated trice. The result shows that growth and yield attributes, seed yield, oil yield and biological yield were influenced significantly by impose of different levels of nitrogen and sulphur fertilizers simultaneously. Significantly the maximum values of above mentioned parameters were recorded with 120 kg N+ 40Kg S ha-1. However 120 kg N+ 30Kg S ha-1 recorded highest net return (63384.27 ₹ ha-1) with the B: C ratio of 1.51. with the view of results obtained, it can be advocated to the farmers of northern hill zone of Chhattisgarh for optimizing the yield, quality and economics of Indian mustard, it should be applied with 90 kg N ha and 30 kg S ha-1 simultaneously.
