OPTIMIZING YIELD AND WATER USE EFFICIENCY OF FURROW IRRIGATED POTATO UNDER DIFFERENT DEPTH OF IRRIGATION WATER LEVELS [Abstract ID: 0608-06]
In Ethiopia, the development of irrigated agriculture plays a key role in improving productivity and food security, but further intensive effort is needed to enhance irrigation water management systems. It is therefore crucial to introduce and adapt the knowledge of irrigation scheduling for each specific crop and location to the beneficiaries. This study aims to improve irrigation water management through the improvement of crop water requirement and irrigation scheduling. This study was conducted in the southern zone of Tigray regional state, Emba Alaje District. The crop water requirement of potato (jalleni variety) was estimated using the CROPWAT 8 software model and determined as 604 mm for the entire growing period. Potatoes (jalleni) were grown under seven treatments of irrigation water application in a complete randomized blocks design with three replications each. Potato yield and water use efficiency was significantly affected (p
