Effects of foliar application of boron and Gibberellic acid on growth and fruit set of phalsa (Grewia asiatica L.)

Abstract

The present experiment entitled “Effects of Foliar Application of Boron and Gibberellic acid on growth and of Phalsa (Grewia asiatica L.)” was conducted at Garden, College of Horticulture, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology Kanpur, Uttar Pradesh in the year 2018-2019. It was carried out in randomized block design with 10 treatment and each treatment replicated thrice. The results of this study on the effect of Boron 20-50 ppm and GA3 30 ppm (with and without) foliar spray on Phalsa of growth regulators boron (Bo) and GA3 were discussed and interpreted in the light of previous research in India and abroad. The study showed significant findings and concluded that T10 (50 ppm boron+30ppm GA3) resulted maximum as length of phalsa shoot and fruit set and at T9 (40 ppm boron+30ppm GA3) resulted as the maximum diameter shoot and fruit (0.94 cm and 1.06 cm), number flowering days (68.77), and length of phalsa fruit (0.07 cm) was maximum.
