Response of plant growth regulators and multi micronutrient on growth, yield and quality of chrysanthemum cv. Ratlam selection

Abstract

The present experiment entitled “Interaction Response of Plant growth regulators and Multi micronutrient on Growth, Yield and Quality of Chrysanthemum cv. Ratlam Selection” was carried out at Jamuvadi Farm, Department of Horticulture, College of Agriculture, Junagadh Agricultural University, Junagadh, during October 2018 to February 2019 and October 2019 to February 2020. The experiment was laid out in Randomized Block Design with Factorial concept (FRBD) consisting two factors with three replications. The treatment comprised with five plant growth regulators and three treatments of multi micronutrient. The results indicated that the foliar application of GA3 @ 150 ppm with multi micronutrient (grade-IV) @ 0.75% foliar spray at 30 & 45 DAT after transplanting in addition to recommended dose of fertilizers (120: 60: 60 kg/ha NPK) produced better growth and yield characters viz., plant height, plant spread, number of branches, stem thickness, number of flowers per plant, number of flowers per plot, weight of single flower, flower yield per plot and flower yield per hectare as well as quality characters viz., vase life of cut flowers, shelf life of loose flowers, in situ longevity of flowers, flower stalk length and flower diameter in chrysanthemum cv. Ratlam Selection.
