Influence of Different Levels of NAA and 2, 4, 5-T on Fruit Drop, Fruiting, Fruit Retention, Growth

The experiment was completed activity at Horticulture Garden, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur (U.P.) during the November 2020- March 2021 and November 2021- March 2022. Sixteen situations viz. four levels of NAA (0, 20, 30 and 40 ppm) and 2,4,5-T (0, 10, 20 and 30ppm) were studies in a Factorial Completely Randomized Design accompanying three replications. Spraying was finished on eleventh November, 2020 in first year and fifteenth November, 2021 in second old age at fruit background stage (Pea Stage) with fine spout fine mist in each treatment to present uniform spray on all over the situation of ber plant. Application of (NAA@40 ppm and 2,4,5-T@30 ppm) significantly maximized beginning fruit set (162.00 and 163.66), maximum product memory (20.39 and 20.43 percent) and maximum beginning fruit set allotment (79.60 and 79.56 per cent). The distance and breadth of fruit was considerably (5.35 and 4.99 cm) and (4.24 and 4.27 cm) respectively raised by application unchanging aggregation mention above. The maximum (36.62 and 36.82 g) fruit pressure and physical features of fruits like book (36.57 and 36.42 cc) recorded under situation (NAA@40ppm and 2,4,5-T@30ppm). The minimum gravel length (0.88 and 0.87 cm), minimum metal diameter (0.88 and 0.87 cm), minimum pebble weight (0.65 and 0.66 gm) and distinguishing seriousness (0.94 and 0.94 g cc-1) significantly establish under (NAA@40 ppm and 2,4,5-T@30 ppm). The yield of ber was significantly raised (39.53 and 40.49) kg per plant, yield per hectare (121.30 and 121.33quintal) with situation combination (NAA@40ppm and 2,4,5-T@30ppm) two together the age of experiment.
