สรุป	Irrigation Scheduling with ETo is a water balance pipeline for determining when and how much to irrigate based on reference evapotranspiration (ETo), soil properties, and crop water demand. Standardized by the FAO in the Penman-Monteith equation and widely adopted globally, this method enables efficient water use in irrigated agriculture.	Crop Yield Estimation is an analytical and predictive pipeline for forecasting final crop yield before harvest or monitoring yield accumulation during the growing season. Developed by agronomic research centers (CIMMYT, ICRISAT, IRRI), this method combines field observations, environmental data, and statistical models to predict grain or biomass output, informing harvest planning, market decisions, and performance evaluation.
