The investigation was carried out at Experimental Farm, Department of Horticulture, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar (Gujarat). The experiment was aimed to determine the best plant growth regulator (s) for regulation of growth and flowering as well as to standardize the optimum concentration of these plant growth regulators for quality flower production of African marigold cv. Lemon yellow. The experiment was laid out in randomized block design with 10 treatments and replicated four times. Plants were planted on 30 x 30 cm spacing and treated with three different plant growth regulators with different concentrations viz. GA3 (100 ppm,150 ppm and 200 ppm), Ethrel (250 ppm, 500 ppm and 750 ppm) and MH (250 ppm, 500 ppm and 750 ppm) along with control (water spray). The results revealed that the GA3 was the most potential growth regulator for producing higher yield with quality flowers and recorded earlier flowering. Ethrel 250 ppm was also found to be effective for getting higher flower yield.
