Correlation has been studied in various growth, quality characters and yield of multicut forage sorghum cultivars which were planted at two locations in a split plot design during kharif season of
2007. The linear correlation study revealed positive and highly significat association between yield and growth/quality components at both the loecations. Perfect correlation (r=1) was between crude protein yield and total N-uptake at both the locations. Among quality and growth parameters, significant positive correlation was noticed at both the locations except between crude protein/N-content and plant height, leaf : stem ratio, dry matter accumulation in third cutting at Lakhaoti, dry matter accumulation and disgestibility in first cutting at Pantnagar, where the positive correlation was not significant.
Key words : Correlation, multicut forage sorghum, protein, digestibility, environment
