Abstract

The present investigation entitled “Effect of GA3, zinc sulphate and borax on fruit drop and fruit cracking of litchi (Litchi chinensis Sonn.) cv. Dehradun” was carried out at garden, Department of Horticulture, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur during the year 2019. During studied seven uniform plants of litchi cv. Dehradun formed the experimental material, four uniform branches in growth and vigour were selected on each tree. The following observations were recorded randomly selected samples of ten fruits from each treatments and three replications. The different treatments used were control (water spray), GA3 25 ppm, GA3 50 ppm, ZnSO4 0.2%, ZnSO4 0.4% and Borax 0.2%, Borax 0.4%. The experiment was planned in a Completely Randomized Design with four replications. The minimum fruit drop percentage was obtained under spray of GA3 25 ppm followed by Borax 0.4%. The foliar application of Borax 0.4% exhibited reduction in cracking of litchi fruits (9.45%) as compared with control (16.15%) followed by Borax 0.2%.

Conclusion

On the basis of sprays of plant growth regulators and mineral nutrients i.e., GA3, ZnSO4 and Borax which influenced different parameters including in this research trial. The foliar application of Borax 0.4 per cent proved most effective and optimum for fruit cracking, length of fruit of litchi fruit cv. Dehradun. The second effective treatment GA3 50 ppm was identifies in present investigation for diameter of fruit, fruit weight, pulp weight.
