| Summary: | Being one of the finest fruit, litchi still need a major attention toward the problems like irregular flowering, poor fruit set, heavy fruit drop, low yield, fruit cracking and poor quality to meet the growing demand of national and international market. Bio-regulators and micro-nutrient are being used by the growers to increase the yield by improving the yield attributing parameters. The present experiment was laid out at the Regional Horticulture Research and Training Station, Dhaulakuan, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni-Solan (HP). Keeping the objective to increase the yield, in the recent studies; trees were subjected to 19 treatments viz. GA3, CPPU, ZnSO4, Boric acid, GA3+CPPU, Boric acid+ZnSO4 andcontrol. The plants treated with ZnSO4 (0.75%) recorded highest total soluble solid (20.40°B) and highest non-reducing sugars (2.98%). Application of Boric acid (0.75%) recorded maximum reducing sugars (11.14%). Foliar spray of boric acid (0.5%)+ZnSO4 (0.5%) significantly increases the total sugar content (13.79%) and decreased the titratable acidity (0.32%) of fruits.
