| Water requirement for plant cane and ratoon cane of Khon Kaen 3 sugarcane variety was studied on Fine-loamy, siliceous Typic Kandiustults namely Warin soil series at Khon Kaen Field Crops Research Center (KKFCRC) since November, 2009 to December, 2011. Plot experimental design was RCB with 3 replications and 6 treatments, consisted of 1) No water (rain-fed condition as control) 2) Supplemental water by drip irrigation as 12.5% of available water capacity (AWC) level from 30-240 DAP 3) Supplemental water as 25.0% of AWC 4) Supplemental water as 37.5% of AWC 5) Supplemental water as 50.0% of AWC and 6) Bare soil. Weekly crop water uptakes for sugarcane and soil evaporation were recorded from the plots of 9x9 m and the crop coefficient (Kc) was re-derived.... |
