Study on the effect of growth regulators and micronutrients on yield components and nutrient uptake of okra (Abelmoschus esculentus L. Moench) cv. ArkaAnamika

摘要

A field experiment was conducted, to study the effect of growth regulators and micronutrients on yield components and nutrient uptake of okra cv. Arka Anamika. Maximum fruit weight and seed number per fruit was observed in the plants sprayed with GA3@50 ppm, highest fruit diameter observed in plants sprayed the plants with NAA@20 ppm and highest fruit length was recorded in plants treated with triacontanol@4000 ppm. Among the micronutrients, ZnSO_4@ 0.4% recorded highest fruit weight, FeSO_4@0.2% given maxmimum fruit length and Borox @ 0.2% recorded fruit diameter. The uptake of N, P and K by plants was maximum with triacontanol @4000 ppm and GA_3@ 50 ppm. Uptake of N maximum in plants sprayed with FeSO_4@ 0.4%, while P and K uptake maximum in plants sprayed with ZnSO_4 @ 0.4%. Growth regulators and micronutrients were foliar sprayed on 20 and 40 days after sowing.
