      Аннотация: The present investigation entitled, “Effect of foliar application of micronutrients and growth regulators on growth, yield and quality of cabbage (Brassica oleracea L. Var. capitata) cv. Golden Acre” was conducted at the Horticultural Research cum Demonstration Farm, Department of Horticulture, B.A.C.A. Anand Agricultural University, Anand during the rabi season of the years 2007 and 2008. The experiment was laid out in Factorial Randomized Block Design with three replications and fifteen treatment combinations, considering three levels of micronutrients (0.0, zinc sulphate 0.5% and ferrous sulphate 0.5%) and five levels of growth regulators (0.0, GA3 @ 50 ppm, GA3 @ 100 ppm, NAA @ 100 ppm and NAA @ 200 ppm) were applied as foliar spray at 3rd and 5th week after transplanting. Among different treatments of micronutrients, zinc sulphate 0.5% recorded significantly highest plant height, leaf area, head volume, head diameter, average head weight, cabbage head yield, ascorbic acid and chlorophyll content.
