The synthetic PGR like 2,4-D and NAA along with 1% urea were investigated on 7 years old trees of lemon cv. Assam Lemon planted with a spacing of 3x3m at the Fruit Research Farm, Department of Fruit Science, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh. The results of the pooled data of winter and summer seasons revealed that the imposition of different treatments had a significant effect on reducing fruit drop and improving the yield of fruits. Among the different treatments, T6 (NAA @ 20 ppm + 2,4-D @ 20 ppm + 1% urea) was found to be most effective with maximum number of fruits/plant at harvesting stage (67.6), yield/plant (8.29 kg) and minimum fruit drop (13.91 %) as compared to control (33.15% fruit drop and yield 4.14kg/plant). However, non-significant effect was found in plant height and canopy spread. Hence, the combination of recommended dose of fertilizers 100:100:100g NPK/plant/year along with 20 kg FYM and synthetic PGR NAA @ 20 ppm + 2,4-D @ 20 ppm + 1% urea foliar spray twice (after fruit setting and fully developed stage) were found to be efficient for increasing yield and productivity in Assam Lemon which can be recommended for reducing fruit drop of this main cultivar lemon for the North East region in the future.
