Abstract

The present experiment was conducted at the Horticulture Garden, Department of Fruit Science, College of Horticulture, of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) during October 2019-March 2020. Well established healthy and uniform trees of Ber cultivar Banarasi Karaka The experiment comprised 9 treatments consisting of foliar spray of GA3, NAA, Zinc Sulphate and control These treatments are as Follow- T0 Control (water spray), T1 (GA3 @0 ppm), T2 (GA3 @20 ppm), T3 (NAA @30 ppm), T4 (NAA @40 ppm), T5 (ZnSO4 @0.4%), T6 (ZnSO4 @0.6%), T7 (GA3 @10ppm + NAA 30ppm + ZnSO4 .04%), T8 (GA3 @20ppm + NAA @40ppm + ZnSO4 @.06%). NAA 40ppm (T4) at fruit setting stage proved significantly effective in increasing fruit weight, length of fruit, fruit volume and reducing fruit drop. and the yield attributes were however, improved with ZnSO4 0.6% (T6) and NAA 40ppm +GA3 20ppm +ZnSO4 0.6%(T8). NAA, GA3 and micronutrients Zn is very effective but spraying of NAA 40ppm hastened fruiting, yielding attributes.

Conclusion

From the present investigation it can be concluded that NAA 40ppm (T4) at fruit setting stage proved significantly effective in increasing fruit weight, length of fruit, fruit volume and reducing fruit drop. and the yield attributes were however, improved with ZnSO4 0.6%(T6) and NAA 40ppm + GA3 20ppm + ZnSO4 0.6%(T8). These results obtained in present investigation in my own research and this is unique and very useful for research workers, orchard owner and farmer of central U.P. So, I would like to suggest the concerning people that spraying of growth regulators i.e. NAA, GA3 and micronutrients Zn is very effective but spraying of NAA 40ppm hastened fruiting, yielding attributes.
