A field experiment was conducted to measure the effect of different time of pinching with different levels of growth retardants on flowering behavior and yield of African marigold. Comprising of three levels of pinching i.e. un-pinched ,pinching at 20 DAT and pinching at 30 DAT and five levels of growth retardants using, control, Cycocel 500ppm, Cycocel 1000ppm, Alar 1500ppm and Alar3000ppm, during winter season of 2007-08 and 2008-09. Among the pinching 20 DAT with Cycocel 1000ppm was the best for improving floral and yield parameters of African marigold. Early pinching (20DAT) with higher concentration of Cycocel (1000ppm) was suggesting for maximum stalk length (9.07and 9.28) and flowers per plant (82.13 and 85.33), fresh weight of flowers (15.43g and 15.66g) yield of flowers per plant (635.33g and 667.93g) and vase life (11.33 days and 12.46 days).
