Effect of foliar application of sulphur on yield, quality and economics of Indian mustard, Brassica juncea (L.) Czern & Coss.

摘要

A study was carried out with mustard in to determine the effect of application of sulfur (gypsum at 20 and 40 g/ha as soil application, thiourea at 0.05 and 0.10%and sulfuric acid at 0.15% as foliar application) on the productivity, quality and economic returns under irrigated conditions. Increase in seed yield with different treatments ranged from 8.9% with foliar application of thiourea at 0.05% at flower initiation to 22.2% with soil application of 20 kg S/ha as gypsum at sowing+foliar application of thiourea at 0.05% over the control. Net returns and benefit:cost ratio were higher with basal application of 20 kg S/ha through gypsum+foliar application of thiourea (0.05%), closely followed by spray of 0.15% sulfuric acid and soil application of gypsum to supply 40 kg S/ha. Application of gypsum decreased the glucosinolate content in defatted seed meal.
