Response of micronutrients and urea foliar spray on yield and nutrient uptake of safflower (Carthamus tinctorius L.) in Chhattisgarh plan

Abstract

The present investigation was conducted in order to augment yield and yield attributes of safflower through foliar spray of micronutrients combination and nitrogen foliarapplication along with General Recommended dose GRD(55:25:20). The experiment was carried out during rabi2013-14 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 (withoutspray),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% Mnfoliar 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% ureafoliar spray. The treatment100%GRD + Fe 0.2% + Mn 0.3%+ Zn 0.5% + 1% ureafoliar spray would be a sound combination of nutrients to get higher capitulum plant-1, seed, number of seeds capitulum-1 seed and stover yields, and sustained the soil physico-chemical properties. The treatments Fe 0.2% + Mn 0.3%+ Zn 0.5% + 1% urea foliar spray with GRD and Fe 0.2% + Mn 0.3%+ Zn 0.5% with GRDwere superiorto application of GRD alone with respect to capitulum plant-1, number of seeds capitulum-1 seed and stover yields, uptake of macronutrientsnitrogen, phosphorus and micronutrients iron, manganese and zinc by safflowerplant and increases seed yield by 28.24 percent over GRD alone.
