Impact of Foliar Feeding of Borax, Zinc Sulphate and Their Intraction on Post Harvest Losses and Economy of Guava (Psidium guajava L.) Cv. Gwalior 27

A field experiment entitled “Effect of foliar application of borax and zinc sulphate on growth, yield and quality of guava (Psidium guajava L.) cv. Gwalior-27” was carried out at Agrotechnology Park, Krishi Vigyan Kendra, College of Agriculture, Gwalior (M.P.) during 2016-2017. The experiment was consisting of 9 treatments having two levels of each Borax (0.2 per cent and 0.4 per cent) and Zinc sulphate (0.4 and 0.6 per cent). The experiment was laid out in Factorial randomized block design with three replications. Among different doses of foliar spray of nutrients, Zinc sulphate @ 0.6 (T5) were found significantly superior over control with respect physiological loss in weight (g) and shelf life of guava. While the minimum spoilage % was recorded with treatment B2Z2 (Borax@ 0.4% + ZnSo4@ 0.6%) at 5th, 10th and 15th day of storage respectively.
