Abstract

A critical investigation was carried out to define the optimal amount of nitrogen and gibberellic acid to produce quality of flowers in Marigold flower during 2011-2012. The research was passed carried out randomly in seven Blocks and doses comprised six degrees of nitrogen (weekly and fourteen days periodically), doses of GA3 (0, 50 and 100 ppm) and two cultivars (Tagetes erecta and Tagetes patula). The 65.94 cm of plant height was noted with nitrogen 1000 ppm per week and GA 3 100 ppm utilized double. GA 3 at 50 ppm form buds of 1.83 cm in size. 6.96 cm flower diameters were eminent having nitrogen dose of 500 while GA 3 of 50 ppm. Nitrogen of 1000 ppm/week determined a sum of 7.25 flowers per plant. 58.25 cm were the stem length noted treated by 1000 ppm/week of Nitrogen and GA 3.

Highlights

A critical investigation was carried out to define the optimal amount of nitrogen and gibberellic acid to produce quality of flowers in Marigold flower during 2011-2012
In Pakistan it is used as gibberellic acid
Result and discussion In over all the species of marigold i.e Tagetes patula (59-63 cm) was established meaningfully heighted than Tagetes erecta (44-56 cm) (Table 1) which is due to the variance in their genomic composition

Summary

Introduction

A critical investigation was carried out to define the optimal amount of nitrogen and gibberellic acid to produce quality of flowers in Marigold flower during 2011-2012. Data was analyzed statistically by using factorial R.B.D. Result and discussion In over all the species of marigold i.e Tagetes patula (59-63 cm) was established meaningfully heighted than Tagetes erecta (44-56 cm) (Table 1) which is due to the variance in their genomic composition. Substantial rise in plant species over control was saw just when marigold were sprayed either with Nitrogen 500 ppm at 7 days or with 1000 ppm of its application at 7 or 14 days. [1] The height marigold (61, 32 cm) were noticed when the dose of Nitrogen (1000 ppm) were sprayed at 7 days intervals.
