Given below are two statements: Assertion (A): The currently used methods for scheduling irrigation are water budget method, soil moisture measurement based, computer models based, keeping a chart and plant-based irrigation method. Reason (R): To achieve better productivity, it is important to work out an efficient and economic irrigation schedule for water use under any given set of agroclimatic condition.
