“…Due to these causes fruit setting was enhanced in present investigation. These findings are in accordance with the reports of Sandhu and Thind [10], Chaurasiya et al, [11], Chaudhary et al, [12] Das et al, [13] in ber, Badal and Tripathi [14] in guava, Saraswat et al, [15] in litchi. The 2,4,5-T probably might be due to providing of right concentration of 2,4,5-T during investigation causing enhancement of vegetative growth of the plants hastening the production of more photosynthesis towards the fruit bearing area which contributed to increase fruit set in plant.…”

The experiment was carried out 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 treatments 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 with three replications. Spraying was done on eleventh November, 2020 in first year and fifteenth November, 2021 in second year at fruit setting stage (Pea Stage) with fine nozzle sprayer in each treatment to give uniform spray on all over the treatment of ber plant. Application of (NAA@40 ppm and 2,4,5-T@30 ppm) significantly maximized initial fruit set (162.00 and 163.66), maximum fruit retention (20.39 and 20.43 percent) and maximum initial fruit set percentage (79.60 and 79.56 per cent). The length and width of fruit was significantly (5.35 and 4.99 cm) and (4.24 and 4.27 cm) respectively increased by application same concentration mention above. The maximum (36.62 and 36.82 g) fruit weight and physical properties of fruits like volume (36.57 and 36.42 cc) recorded under treatment (NAA@40ppm and 2,4,5-T@30ppm). The minimum stone length (0.88 and 0.87 cm), minimum stone diameter (0.88 and 0.87 cm), minimum stone weight (0.65 and 0.66 gm) and specific gravity (0.94 and 0.94 g cc-1) significantly found under (NAA@40 ppm and 2,4,5-T@30 ppm). The yield of ber was significantly increased (39.53 and 40.49) kg per plant, yield per hectare (121.30 and 121.33quintal) with treatment combination (NAA@40ppm and 2,4,5-T@30ppm) both the years of experiment.

Among subtropical fruits Ber (Zizyphus mauritiana L.) one of the most common fruit crop, grown under neglected soil types. It is a drought hardy and can grow under the most hazardous conditions of soil, water and climate and thus it has rightly been recommended for the arid and desert area of India [1]. It is found growing wild as well as in cultivated forms throughout the warmer regions up to an altitude of 1500 metres above Mean Sea Level. The experiment comprised 13 treatments consisting of foliar spray of GA3, NAA, Urea and control. The treatments are as follows- T0 Control (water spray), T1 (GA3 @10 ppm), T2 (GA3 @20 ppm), T3 (NAA @20 ppm), T4 (NAA @40 ppm), T5 (Urea @1.0%), T6 (Urea @1.5%), T7 (GA3 @10 ppm + NAA @20 ppm + Urea @1.0%), T8 (GA3 @20 ppm + NAA @40 ppm + urea @1.5%). Mentioned solutions with different concentration were sprayed by foot sprayer in the morning hours and selected branches were fully drenched. On the basis of sprays of plant growth regulators i.e. GA3 and NAA and urea as well as their combined treatments influenced different parameters in this research trial. The combined treatments of GA3 20 ppm + NAA 40 ppm + urea 1.5% maximized initial fruit set, fruit retention, fruit volume, length of fruit, fruit diameter, fruit weight, pulp weight, pulp/stone ratio and minimized the fruit drop, stone weight content. The second effective treatment was GA3 10 ppm + NAA 20 ppm + urea 1.0% identified in present investigation.
