Quality of mulberry (Moms indica l.) leaves as influenced by integrated nitrogen management practices

A field experiment on the effect of integrated nitrogen management practices on growth, yield and quality of mulberry (Morus indica L.) leaves was conducted on a sandy loam soil in the farmers’ field of Mayurapura village, Hunsur taluk, Mysore district, Karnataka state. The treatments consisted of organic manures viz., farm yard manure, vermicompost and poultry manure and inorganic fertilizers viz.. urea in various combinations to supply 25, 50, 75 and 100% nitrogen and in addition, no nitrogen and recommended dose of farm yard manure and fertilizers were also included for comparison. The leaf quality parameters viz., moisture (76.63%), nitrogen (2.85%) and crude protein (17.82%) were higher in recommended dose of. farm yard manure and fertilizers. The phosphorus (0.29%) and potassium (2.85%) contents of leaves were higher in 100% nitrogen through vermicompost, whereas magnesium content of leaves (0.72%) was higher in 50% nitrogen each through poultry manure and urea.
