Variance and correlation analysis were carried out among nutritional composition of mulberry leaves taking three varieties (BSRM-5, BSRM-18 and BSRM-19) in three different seasons under six different doses of NPK fertilizers including control during 1990-91. The variance analysis showed that varieties, treatments and seasons have significant effects on the nutritional composition of mulberry leaves. Simple correlation studies indicated that all the nutritional components are closely interrelated with each other and directly or indirectly influenced by one another. It was also found from partial correlation analysis that nutritional components viz., free sugar, reducing sugar, soluble carbohydrate and starch are strongly associated with protein content of mulberry leaves. The multiple correlation analysis again showed that soluble carbohydrate and starch as well as free sugar and reducing sugar contents influence the protein content of mulberry leaves more strongly than all other nutrient contents studied.
