Abstract

The present investigation was carried out during cool season at Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Science Prayagraj (U.P.), India. The experiment was laid out in randomized block design with three replications of 9 treatments. Treatments consisted of Full corm, ½, ⅓ corms (cut corms) and growth regulators GA3 @150ppm (full corm), 200ppm (½ corm, 250ppm (⅓ corm), 300ppm (full corm), 350ppm (½, corm), 400ppm (⅓ corm). Among the different treatments, T3 (GA3@ 150ppm full corm) gave the best performance in terms of good growth, flowering and corm production which includes Plant Height, Number of leaves, Days to spike emergence, Days to opening of the first floret, First florets durability (days), Rachis length(cm), Number of florets/ spike, Number of spike/plant, Spike yield/ha, Number of cormlets/planted corm, Corm yield/ha, No.of corms/plant, Weight of Corms/plot.
