ABSTRACT
An experiment was conducted to find out the effect of micronutrients and GA3 on growth, flower yield, seed yield and seed quality parameters at Horticultural College and Research Institute, Dr. Y.S.R. Horticultural University, Venkataramannagudem. The experiment was replicated thrice in split plot design consists of five treatments including control (ZnSO4 @ 0.5 %, FeSO4 @ 1 %, Boric acid @ 0.5 %, GA3 @ 300 ppm and control). Foliar application of micronutrients and GA3 followed at 20 and 40 DAT. Among the foliar sprays GA3 @ 300 ppm recorded maximum plant height, plant spread, number of branches per plant, stem diameter, biomass, number of flowers per plant, flower diameter, flower yield/plant, flower yield/square meter, flower yield/ha, seed yield/plant, seed yield/square meter, seed yield/ha, highest 1000 seed weight, seed germination %, seed moisture content %, seedling dry weight, seedling vigour index and minimum number of days to flower bud initiation, flower opening, 50 % flowering, and duration of flowering followed by ZnSO4 @0.5 %.
Key words :
Flowering & yield, Foliar spray, GA3, Micronutrients, Seed yield & quality, Tagetes erecta.
