Abstract: The present investigation was conducted on seven-years-old trees of sweet orange var. “Nucellar” growing at Sweet Orange Research Station Badnapur. The different chemicals viz., Urea (0.5, 1.0 and 2.5%), GA3 (30, 50 and 70 ppm), NAA (15, 20, and 25 ppm), Urea (1%)+ GA3 (30,40 and 50 ppm) and CPPU (20, 40 and 60 ppm) were sprayed at prior to flowering, full bloom and pea stage along with a control. The minimum percentage of fruit drop was observed when NAA sprayed at 15 ppm (14.19%) which is followed by NAA (20 ppm), GA3 (50 ppm,) GA3 (30 ppm), and NAA (25 ppm) respectively. The maximum fruit set was observed in treatment Urea (1%) + GA3 (70 ppm) (67.67) which is followed by GA3 (50 ppm), NAA (25ppm), NAA (20ppm) and GA3 (70 ppm). Thus it proves that the application of plant growth regulators and chemicals most effective against the control of fruit drop and increasing fruit set.
