Effect of combined foliar application of micronutrient and nitrogen on quality parameter of safflower in Vertisol of Chhattisgarh

Abstract

The present investigation was conducted to access quality parameters of safflower through foliar spray of micronutrients and nitrogen combinations along with General Recommended dose during rabi 2013-14 and 2014-15 at the Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh in randomized block design with three replications and twelve treatments namely absolutely control, 100% GRD (without spray), 100% GRD with tap-water spray, 100% GRD+ 1% N foliar spray, 100% GRD+ 0.2% Fe foliar spray, 100% GRD+ 0.5 % Zn foliar spray, 100% GRD+ 0.3% Mn foliar spray, 100% GRD+Fe 0.2% + Mn 0.3% foliar spray, 100% GRD+ Fe 0.2% + Zn 0.5% foliar spray, 100% GRD+ Mn 0.3% + Zn 0.5% foliar spray, 100% GRD+Fe 0.2% + Mn 0.3% + Zn 0.5% foliar spray and 100% GRD + Fe 0.2% + Mn 0.3% + Zn 0.5% + 1% urea foliar spray. The treatments 100% GRD + Fe 0.2% + Mn 0.3% + Zn 0.5% + 1% urea foliar spray was a sound combination of nutrients to get highest oil yield (529.78 kg ha-1) followed by Fe 0.2% + Mn 0.3% + Zn 0.5% with GRD (508.33kg ha-1) were superior to application of GRD alone (393.15kg ha-1) and increase in oil yield was by 34.75 and 29.30% percent over GRD alone respectively.
