ABSTRACT

The study was conducted in 10 years old walnut orchard in Dr.Y. S. Parmar University of Horticulture and Forestry, Nauni-Solan(H.P.) to find out the effect of integrated nutrient management on tree growth, yield and nut quality of walnut (Juglans regia L.). There were 13 different treatments in combination of organic and inorganic fertilizers. Changes in tree-height, trunk-girth and protein and oil contents in nuts were recorded in percentage and shoot extension in meter. Statistical analysis of the data was carried out as per the method described by Cochran and Cox (1963). Recommended dose of NPK with 50 kg vermicompost produced highest increase in tree height, trunk girth and shoot extension. However, highest improvement in nut yield and quality were observed with three fourth of recommended NPK and 68.75 kg vermicompost
