Abstract
The present investigation entitled “Efficacy of foliar feeding of Ca, Zn and Cu with and without Borax on Fruit drop and Bio-Chemical attributes of winter season guava (Psidium guajava L.) cv. L-49” was conducted at guava orchard of Kalyanpur nursery, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur 208002 during 2019-2020. 39 guava trees with even size and vigour were selected and were sprayed with various concentrations of different nutrients (Ca(NO3)2 @ 0.50% and 1%), (ZnSO4 @ 0.50% and 1.0%) and (CuSO4 @ 0.60% and 0.80%) with and without Borax (1%). Thirteen treatments were replicated three times as part of the RBD (Randomised Block Design) investigation. Fruits were examined in the laboratory of the Department of Fruit Science, C.S.A.U.A&T., Kanpur, for their physical and biochemical characteristics. The results of the present study revealed that fruit drop (33.94%) and bio-chemical attributes that is, Total soluble solids (13.54 0Brix), Acidity (0.46 %) and Ascorbic acid (194.30 mg/100g pulp) were improved significantly with the use of ZnSO4 1.0% + Borax 1.0% (T10).
