Effect of Amino acid formulation as foliar spray on biochemical constituents of V-1 mulberry variety

Abstract

A study on “Effect of Amino acid formulation as foliar spray on biochemical constituents of V-1 mulberry variety was conducted by utilizing the established V-1 mulberry garden at department of Sericulture, UAS, G.K.V.K., Bengaluru during 2016-17. Spraying of 3.5 % amino+ spray on 25th and 35th day after pruning recorded maximum biochemical parameters of V-1 mulberry such as leaf moisture, carbohydrates and protein content (74.7, 25.76 and 23.48 per cent respectively) chlorophyll (33.23), nitrogen (3.76 %), phosphorous (0.46 %), potassium (1.53 %), calcium (1.69 %), magnesium (0.57 %), sulphur (0.49 %) and zinc (22.75 ppm) contents recorded significantly high in 3.5 % amino+ spray on 25th and 35th day after pruning. The details are discussed.
