Effect of Foliar Feeding of Nutrients and Gibberellic Acid on Yield and Quality of Mango (Mangifera indica L.) Fruits cv. Dashehari

Background: Mango is national fruit of India and it is suffering with many problems in cultivation among which fruit drop is major which leads to low production. So, the application of nutrients and plant growth regulators would be helpful to minimize fruit drop and to get better yield with quality fruits. The aim of the present study to study the effect of foliar feeding of nutrients and gibberellic acid on yield and quality of mango (Mangifera indica L.) fruits cv. Dashehari. Methods: This study was conducted at Horticulture Farm, Rajawala and in PG Laboratory of Doon (PG) College of Agriculture Science and Technology, Camp Road, Selaqui, Dehradun during the years 2017-2018 with the use of GA3 (100 ppm), Urea (1.5%) and Boron (0.2%) alone and in combinations, these all were compared with control treatment. Result: All the treatments used were found better to improve the yield and quality of fruit but the treatment combination of Boron (0.2%) + Urea (1.5%) + GA3 (100 ppm) was found significantly effective to increase the fruit retention, fruit yield, fruit length, fruit width, fruit weight, total soluble solids, ascorbic acid and sugars. However, fruit drop and titrable acidity were drastically decreased while the fruit volume was found non-significant.
