The control treatment was taken as drip with no mulch. Adjusted FAO Kc predict higher value than sensor based Kc values at both irrigation regimes. Sensor based Kc-mid values were lower by 12.99% and 30.04% than the adjusted FAO Kc-mid value at 1.0 IW/ETc and 0.8 IW/ETc respectively. Biodegradable plastic mulch reduced Kc-ini value by 72.26% and 66.54% over control at 1.0 IW/ETc and 0.8 IW/ETc respectively. Overestimated adjusted FAO Kc values caused a loss of 78.13mm and 66.54mm of precious water at 1.0 IW/ETc and 0.8 IW/ETc respectively. This study admonishes blind adoption of published FAO Kc curves, for mulch conditions. ER -
