Effect of NAA and zinc sulphate application on nutritional status of fruits and leaves of mulberry (Morus alba L.)

Abstract

The investigation entitled “Effect of NAA and zinc sulphate application on fruit drop, yield and quality attributes of mulberry (Morus alba L.)” was conducted during 2018-19. Significant improvement in the leaves and fruit nutrient (Nitrogen, Phosphorus, Potassium and Zinc) concentrations was obtained with the foliar sprays of zinc sulphate and NAA. Maximum N, P and K content was found with the foliar spray of zinc sulphate @ 0.4 per cent and NAA @ 60 ppm, while maximum zinc content was found with the foliar spray of zinc sulphate @ 0.6 per cent and NAA @ 60 ppm.
