Abstract:
In order to represent valley areas of Manipur, the current study set out to determine the crop water and irrigation water requirements for mustard crop at different sites throughout the Imphal West district of Manipur. Total net irrigation requirement (NIR) of mustard crop was highest in the year 2019-2020 at 211 mm/season and the average net irrigation requirement of mustard using the FAO-56 equation is evaluated at 193 (±16) mm/season. Therefore, this method can be suitably used to predict the water demand of mustard. Thus, this study contributed to the information and effective management on the net irrigation water requirements for mustard crop would aid in the intelligent use of available water and strategies for sustainable crop production in Imphal west area of Manipur, North East India.
