The present investigation was undertaken on the effect of foliar application of NAA, GA3 and Zinc Sulphate on fruit drop, growth and yield of ber (Zizyphus mauritiana Lamk.) . Banarasi Karaka at Horticulture garden, Department of Horticulture, Chandra Shekhar Azad University of Agriculture and Technology Kanpur (.), during the year 2016– 2017. The experiment was conducted in randomized block design with ten treatments comprising of each three levels of NAA @ 10, 20 and 30 ppm, GA3 @ 20, 30 and 40 ppm and Zinc Sulphate @ , and % and control (water spray), respectively. Spray was done in month of November at fruit setting stage. The results clearly showed that the foliar spray of ZnSO4 @ proved most effective in recording maximum initial fruit setting (159), fruit retention () and minimum fruit drop (). The spray of GA3 at 20 ppm resulted in maximum fruit length ( cm), fruit width ( cm), fruit volume ( cc), fruit weight ( g) and weight of fruit pulp ( g). It was also observed that the foliar spray of ZnSO4 @ was proved to be most effective in recording maximum fruit yield per tree ( kg). | Effect of foliar application of NAA, GA3 and Zinc sulphate on fruit drop, growth and yield of ber (Zizyphus mauritiana Lamk.) .
