Description |
An investigation entitled ?Impact of planting dates, micronutrients and GA3 on flower and seed production in African marigold (Tagetes erecta L.)? was conducted at HC&RI, Venkataramannagudem, during 2013-2014. The experiment was laid out in split plot design to study the effect of planting dates (July 13, august 13, September 13 and October 13) and foliar spray of micronutrients (ZnSO4 @ 0.5 %, FeSO4 @ 1.0 %, Boric acid @ 0.5 %) and GA3 @ 300 ppm on flower and seed production in African marigold. Among the planting dates July 15th planting recorded maximum plant height, plant spread, number of branches per plant, stem diameter, biomass and also increased the duration of flowering, number of flowers per plant, flower yields/plant, seed yield/plant followed by August 15th. In other hand September planting results highest flower diameter, average flower weight, 1000 seed weight, seed germination %, seedling dry weight and seedling vigour index Followed by August15th. Besides October planting showed minimum number of days to bud initiation, flower opening, 50 % flowering and duration of flowering followed by September 15th. Among the foliar application (micronutrients & GA3) at 20 DAT & 40 DAT, GA3 @ 300 ppm has enhanced the plant height, plant spread, number of branches per plant, stem diameter, biomass, flower diameter, number of flowers per plant, flower yield, seed yield and early flower bud appearance, flower opening, 50 % flowering. On the other hand, pre-harvest application of ZnSO4 @ 0.5 % was found to be the best treatment next to GA3 as it increased all vegetative and yield parameters of marigold flowers. Among all the interaction treatments July 15th with application of GA3 @ 300 ppm was found to be the best treatment combination for maximum characters |
