Abstract

The field experiment was conducted at Horticulture Research Farm of Choudhary Charan Singh University Campus, Meerut U.P. during 2011-12. The nine treatments A1 (Azotobacter by Root Treatment 0.20g/15 plants), A2 (Azotobacter by Soil Treatment 0.40g/plot), G1 (Gibberellic acid 100 ppm spray at 30 DAT), G2 (Gibberellic acid 150 ppm spray at 30 DAT), A1G1 (Azotobacter by Root Treatment 0.20g/15 plants and Gibberellic acid 100 ppm spray at 30 DAT), A1G2 (Azotobacter by Root Treatment 0.20g/15 plants and Gibberellic acid 150 ppm spray at 30 DAT), A2G1 (Azotobacter by Soil Treatment 0.40g/plot and Gibberellic acid 100 ppm spray at 30 DAT ), A2G2 (Azotobacter by Soil Treatment 0.40g/plot and Gibberellic acid 150 ppm spray at 30 DAT) and A0G0 (No Azotobactor and No Gibbrellic acid) were evaluated in Randomized Block Design with three replications. The experimental finding revealed that the treatment A2G2 (Soil treatment with Azotobacter + Spray of GA3 @ 150 ppm) gave the maximum plant height, maximum number of primary branches per plant, maximum number of secondary branches per plant, maximum plant spread, minimum number of days taken for flower bud appearance, maximum number of flowers per plant, maximum flower diameter, maximum fresh weight of flowers per plant and maximum yield of flower in comparison to individual application of GA3 and Azotobacter.
