Performance evaluation of furrow systems in corn farms to improve irrigation efficiency under farmer management (Case study: Moghan Agro-industry and husbandry)

Performance evaluation of current status of irrigation systems and introducing practical approaches can help to use water more efficiently in field. This study was conducted to evaluate the furrow irrigation systems in corn farms of Moghan agro-industry and husbandry, Parsabad, Ardebil, in 2015. Evaluation of these systems was conducted in seven corn farms. The results indicated that the average water application efficiency, storage efficiency, infiltration efficiency, distribution efficiency, application efficiency of low quarter, distribution uniformity of low quarter and potential efficiency of low quarter are 41.90%, 92.48%, 75.28%, 91.44%, 36.85%, 85.01% and 59.72%, respectively. The reason for the low value of irrigation application efficiency is the difference between application efficiency of low quarter and potential efficiency of low quarter. Therefore, the poor management of surface irrigation was concluded. Proper furrow run and cutoff time and utilizing siphon can improve the current status drastically and will result in irrigation efficiency improvement.
