One of the commercially exploited flower crops belonging to the asteraceae family is Marigold. In many states, the commercial extraction of marigold carotenoids is currently becoming popular in our country. Proper crop management techniques are needed to produce cost-effective yields and improve the quality of marigold flowers. Number of harvestings manifest that the harvestings were not far from each other. The average number of harvestings resulted as non-significant. The range of harvestings was from 7.67 to 6.33. The number of flowers was significantly influenced by different growth regulators’ treatment. The maximum average number of flowers per plant were recorded under the treatment T1 - GA3 @ 100 ppm (41.12), followed by T2 - GA3 @ 200 ppm (40.80). The yield of flowers per plant was differed due to the effect of plant growth regulators. As the PGR influenced the size and weight of flowers, the weight per plant ultimately was increased by treatment of GA3 and NAA. Maximum average yield per plant was noted in T1 - GA3 @ 100 ppm (424.83 g/plant). The yield per plant in T9 - Control recorded was (387.17 g/plant). The flower yield per plot recorded was effectively influenced by application of PGRs. The yield per plant was increased which eventually increased yield per plot of GA3 and NAA treated plants. Maximum average yield was recorded in T1 - GA3 @ 100 ppm (12.74 kg/plot) treated plots. Flower yield was significantly influenced by different growth regulator treatments. Maximum average flower yield was observed under the treatment T1 - GA3 @ 100 ppm (20.98 t/ha), followed by T2 - GA3 @ 200 ppm (20.76 t/ha).
