| Abstract | Drought stress is a main problem of sugarcane production in the Northeast ofThailand which causes the low yield. Application of irrigation could influence onsugarcane yield. The objective of this study was to determine appropriate areas forirrigation improvement in sugarcane planting areas in a radius of 60 km of the E-SaanSugar Industry Co., Ltd., Sam Chai District, Kalasin Province. Sugarcane planting areasoverlaid with soil type and climate zone were used to define a simulation mapping unit(SMU) for inputting to the Canegro sugarcane model. Climate data set from year 2000-2009 was used to stimulate model of sugarcane yield in rainfed and irrigated crop areas inpast 10 years. Sugarcane cv. KK3 was used in this study. Yield gap between rainfed andirrigated crop areas overlaying with underground water map were calculated by each SMUto find cost and benefit for irrigation method. Increasing of yield and cost of irrigation wereanalyzed to determine suitable area for irrigation. Results from simulation showed thatirrigation could improve sugarcane yield by 1.1- 8.4 ton/rai depending on SMU. For eachSMU needed 138-658 mm for irrigation. Irrigated sugarcane production costed higher 815-9,561 Bath/rai than rainfed sugarcane resulting in returns of -331-11,034 Bath/rai. Accordingto the obtained model, 381,359 rai of sugarcane planting area (60.45%) showed the mostsuitable for improving sugarcane yield by irrigation, whilst 149,133 rai (23.64%) were thelands that moderately suited to irrigation improvement. Irrigation system in another100,005 rai (15.85%) of sugarcane planting areas in this study slightly increased the sugarcane yield and 418 rai (0.06%) werenot suitable for irrigation. This studyindicates that irrigation can improvesugarcane yield but different in each area.Thus, determination of suitable area forirrigation can decrease the risk ofinvestment. |
