Abstract

An experiment was conducted at Horticulture Garden, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology Kanpur during the year 2020-21. Factorial Completely Randomised Design was used with three replications and sixteen treatments with four levels each of NAA (0, 20, 30 and 40ppm) and Zinc (0, 0.2, 0.4 and 0.6%) and their combination. Spraying was done twice i.e. before flowering and at Pea stage respectively. Sprays of 30ppm NAA significantly maximized length of fruit (3.02cm), fruit diameter (2.76cm), fresh weight of fruit (18.91g), pulp weight (13.00g), marketable yield (68.50 kg/plant), total sugar (13.20%) and TSS (19.46°Brix). Control (N0) revealed 2.66cm, 2.35cm, 17.51g, 11.46g, 47.08kg/plant, 11.98% and 18.42°Brix values respectively. Zinc applied at 0.4% proved effective and significantly enhanced in length of fruit (3.04cm), fresh weight of fruit (19.09g), pulp weight (13.12g) and TSS (19.60°Brix) over control (Z0) recorded 2.58cm, 17

Conclusion

On the basis of results obtained in present investigation it is concluded that individual application of NAA and zinc brought about significant changes in plant metabolism. NAA 30ppm improved fruit set, fruit retention, length of fruit, diameter of fruit, fresh weight of fruit, pulp weight, rind weight, marketable yield, total sugar and TSS content. It’s also minimized important desired characters i.e. cracked fruits and fruit drop. Zinc 0.4% dose was found more effective on enhancing fruit set, fruit retention, length of fruit weight, weight of fresh fruit, pulp weight, marketable yield and TSS content and it’s also minimized fruit drop, cracked fruit and seed weight. NAA 30ppm in association with 0.4% zinc was more effective on length, diameter of fruit and rind weight, marketable yield, sugar content and TSS content and it also minimized cracked fruits in litchi. Thus, in view of the above achievements 30ppm NAA in consumption with 0.4% zinc may be recommended s
