Abstract
Studies were undertaken at Sugarcane Research Station, Thiruvalla during 1996–97, 1997–98 and 1998– 99 on ratoon crop of sugarcane to determine the effect of time and method of K application. The results revealed that soil application of K at 75 per cent of the recommended dose as basal along with 25 per cent of the recommended dose of K as foliar application at 90 DAP resulted in appreciable increase in millable cane count and cane yield. However, the juice quality remained unaffected with treatment effects. It was also observed that K application beyond 90 days after ratooning (DAR) either through soil or foliar application did not show any significant effects on cane yield and juice quality. Similarly 100 per cent K application as foliar spray could not enhance the cane yield and improve the juice quality.
