Abstract: The field experiment entitled “Effect of different plant growth retardants on plant growth, flowering and yield of African Marigold (Tagetes erecta L). cv. Pusa Basanti” was carried out at Horticultural Experimental Field, Department of Horticulture, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Deemed-to-be University, during rabi season of 2014-2015. Ten treatment combinations with one cultivar were tried in Randomized Block Design (RBD) with three replications. Treatment details were T0 (Control), T1 (CCC @ 750 ppm), T2 (CCC @ 1000 ppm), T3 (CCC @ 1250 ppm), T4 (Ethephon @ 250 ppm), T5 (Ethephon @ 500 ppm), T6 (Ethephon @ 750 ppm), T7 (MH @ 200 ppm), T8 (MH @ 300 ppm) and T9 (MH @ 400 ppm). On the basis of investigation, it may be concluded that treatment T2 with (CCC @ 1000 ppm) was found to be best treatment in terms of growth and flowering parameters observed viz., Plant height (46.87 cm), no. of branches per plant (5.78), plant spread (39.33), leaves per plant (679.13), days taken for first flower bud initiation (50.38), days taken for first flowering after transplanting (61.23), diameter of flower (5.94 cm), flower stalk length (8.84 cm). This treatment also showed maximum yield parameters viz., no. of flowers per plant (24.12), flower yield per plant (210.09 g), flower yield per ha (13.13 t/ha) and flower quality by observing fresh flower weight (12.67 g) in African marigold (Tagetes erecta L). cv. Pusa Basanti. The economics analysis reveals that maximum benefit cost ratio (1: 2.69), net income, gross income are maximum with this treatment.
