Effect of foliar nutrition of Zinc sulphate, borax and NAA on yield and quality of Guava (Psidium guajava L.) cv. Allahabad Safeda

Abstract

A field experiment entitled “Effect of foliar nutrition of Zinc Sulphate, Borax and NAA on yield and quality of guava (Psidium guajava L.) cv. Allahabad Safeda” was conducted at the Instructional cum research fruit orchard Department of Fruit Science, K.N.K. College of Horticulture Mandsaur, during 2015-16. The experiment was consisted of 13 treatments having three doses of each Zinc sulphate (0.4%, 0.6% and 0.8%), Borax (0.4%, 0.6% and 0.8%) and NAA (50 ppm, 75 ppm and 100 ppm). The experiment was laid out in randomized block design with three replications. Result revealed that Borax 0.8% + ZnSO4 0.8% + NAA 100 ppm (T12) was found significantly superior over control and rest of treatments with respect to yield and quality attributes of guava.
