Effect of Foliar Application of Various Concentrations of NAA and GA3 on Fruiting, Yield and Quality Attributes of Ber cv. Banarasi Karaka, India

Abstract

To study the effect of foliar application of different concentrations of NAA and GA3 on fruiting, yield and quality of ber, an investigation was carried out in the Garden, Department of Fruit Science, C. S. Azad University of Agriculture and Technology, Kanpur during the year 2021-22 on ber cv. Banarasi Karaka. Results of the investigation revealed that the significantly main effect among the spray of various concentrations of NAA 30 ppm results, maximum number of fruit set (165.50), minimum fruit drop (85.15%), maximum fruit retention (14.45%), fruit weight (18.32g), yield (44.02 kg/tree), volume (16.17cc), length (4.36cm), diameter (2.56cm), pulp weight (16.12g), total soluble solids (15.480Brix) and total sugars (10.32%) against control (water) treatment. Spray with various concentrations of GA3 showed significant results, having maximized number of fruit sets (160.00), minimum fruit drop (89.16%), maximum fruit retention (10.16%), weight (15.95g), yield (36.78kg/tree), volume (16.17cc), length (4.36cm), diameter (2.56cm), pulp weight (16.12g), total soluble solids (15.480Brix) and total sugars (10.32%) were recorded with spray of 30ppm GA3 against control (water spray) treatment. Interaction effect among various concentration of NAA and GA3 has significantly maximized with fruit retention (16.24%), volume (16.70cc), length (4.47cm), diameter (2.61cm), pulp weight (17.55g) and total sugars (10.59%), while non-significantly results showed highest number of fruit set (167.00), minimum fruit drop (83.76%), maximum fruit weight (19.40g), fruit yield (45.70 kg/tree) and total soluble solids (16.620Brix) with application of NAA and GA3 @ 30ppm against control (water spray) treatment. This study revealed that for realizing higher fruiting, fruit yield and quality of ber plants should be spread with GA3 and NAA @ 30ppm under north Indian plains of Uttar Pradesh.
