Abstract

A study on foliar feeding of GA3 and NAA on fruit drop, retention, yield and quality of ber fruit (Ziziphus mauritiana Lamk.) cv. “Banarasi Karaka”. The investigation was conducted at Horticulture Garden CSA University of Agriculture and Technology, Kanpur during the year 2020-21 on ber fruit. Results revealed that the sprays of 30 ppm significantly maximized (161.75) fruit set against control N0 (159.50). 30 ppm GA3 significantly maximized (163.50) fruit set against control G0 (157.25). The minimum 90.09 % fruit drop was shown under 40 ppm NAA over control N0 (91.95 %) 30 ppm GA3 significantly minimized 89.75% fruit drop against control G0 (92.97%). Interactive treatment N2G2 significantly produced lesser (89.19 %) fruit drop against control N0G0 (95.02 %). NAA 40 ppm revealed maximum of 15.97 % fruit retention over control N0 (12.87 %). GA3 30 ppm maximized 16.76% fruit retention over control G0 (10.93%) interactive treatment N2G2 significantly maximized (17.84 %) fruit retentio

Conclusion

On the basis of results, plant growth regulators NAA and GA3 used as a tool in improving the performance of ber cv. ‘Banarsi karaka’ fruits with respect to fruiting parameter, yield and quality attributes in the present investigation. The results concluded that NAA 30 ppm maximized fruit set, yield and total sugar and it was exhibited prominent as second effective treatment in fruit retention, TSS and ascorbic acid content. NAA 20 ppm and 40 ppm maximized less parameter in comparison of NAA 30 ppm considerably. Similarly, GA3 40 ppm promoted significantly maximum yield and ascorbic acid and also enhanced fruit set, fruit retention and yield while lesser fruit drop was seen. The effectiveness of GA3 20 and 30 ppm exhibited positive but did not expressed superimpose to GA3 40 ppm treatment. So, on the conclusion of present investigation it is advice to the concerning peoples, orchardist and farmers of central U.P. for spraying of NAA 30 ppm and GA3 40 ppm at the time of pre bloomin
