In a study conducted at Sugarcane Research Institute, AARI, Faisalabad, Pakistan during the year 2006 and 2007, four K2O levels (0, 112, 168 and 224 kg/ha) were applied to sugarcane crop at three different times i.e. at sowing, 90 days after sowing (DAS) and half at sowing + half at 90 DAS. Layout system was RCBD with three replications having a net plot size of 6 x 8 meter. The results revealed significant differences among all treatment means except germination percentage and number of shoots. K2O @ 168 kg in two splits; half at sowing + half at 90 DAS produced maximum cane length (305 and 290 cm), number of millable canes (13.0 and 12.7/m2) and stripped cane yield (116 and 107 tons/ha) during the year 2006 and 2007, respectively. A positive and strong relationship was observed between stripped cane yield and number of shoots, cane length, cane girth and number of millable canes.
