Abstract: Present research was conducted during 2017 – 18 to examine the influence of plant growth regulators on fruit size and yield in sapota CV. Kalipatti. The experimental design is Randomised Block Design with ten treatments, replicated thrice on 15-year-old sapota orchard of HRS, Konda Mallepally, Nalgonda. Treatments are viz., T1 -Control, T2 -NAA 250 ppm, T3 -NAA 300 ppm, T4 -NAA 350 ppm, T5 -2,4-D 40 ppm, T6 -2,4-D 50 ppm, T7 -2,4-D 60 ppm, T8 -Ethephon 350 ppm, T9 -Ethephon 400 ppm and T10 -Ethephon 450 ppm. Time of spraying of growth regulators is 1st spray at flowering stage and 2nd spray is at one week of fruit set. The maximum fruit weight (105.28 g), fruit length (4.99 cm), fruit diameter (62.42 mm) and volume of fruit (102.91 ml) was found in the treatment with foliar application of NAA at 350 ppm. The highest fruit yield per tree (23.52 kg/tree) and yield per hectare (26.13 t/ha) was recorded in the treatment with foliar application of NAA at 350 ppm, followed by Ethephon at 450 ppm 21.02 kg per tree and 23.36 tonnes per hectare, respectively. Hence, it can be concluded that foliar spray of NAA at 350 ppm recorded maximum fruit size and yield.
