Cause-effect relationship of cane and sugar yield components in sugarcane

Abstract

The cause and effect relationship of cane and sugar yield components studied in the plant crop performance of 48 hybrid varieties revealed that circumference of cane, number of millable canes per plot and length of cane had high direct contributions for cane yield. Pol percentage at 12th month had maximum direct effect on CCS percentage. Among the two components contributing to sugar yield, cane yield had maximum contribution rather than CCS percentage, thereby suggesting that increasing the cane yield through its components like circumference of cane, number of millable canes or length of cane, the sugar yield can also be increased, through correlated response.
