Foliar application of plant growth regulators, viz.; salicylic acid (100ppm & 200 ppm) and brassinolide (10 ppm & 20 ppm) in mustard variety vaibhav grown under water stress (rainfed) condition, significantly increased the seed yield (5.24Q/ha to 6.48Q/ha), moisture content, 1000 seed weight (from 4.15g in control to 4.87g in treatment T3 (salicylic acid @200 ppm applied twice) and oil content (from 36.75 to 40.36%). There was a progressive increase in oil content with increase in rate of growth regulators, from 38.32 to 39.35% with increase in rate of salicylic acid application and from 37.75 to 40.36% with increase in rate of brassinolide application. Oil yield varied significantly from 1.92Q/ha in control to 2.54Q/ha in T3 (salicylic acid @ 200ppm application twice), Refractive index varied from 1.4592 to 1.4680. Application of salicylic acid and brassinolide to mustard resulted in less accumulation of glucosinolates as compared to control (without any treatment) which accumulated high level of glucosinolates.
