Abstract

In the situation of improving water productivity, there is increasing interest in deficit irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. For this authorize, the study was conducted during the dry season for three years from December 2017 to May 2019 to study the effect of deficit on application efficacy, storage efficiency, distribution uniformity and irrigation water use efficiency of potato and onion. The deficit water level used were 75 and 50% CWR lined with full irrigation 100%. From the result, average of application efficiency (Ea), storage efficiency (Es) and distribution uniformity (DU) of the three water levels (100%, 75% and 50%) were 60.97%, 70.27%, 75.4%, 55.45%, 62.84%, 88.68%, 88.24%, 87.61% and 89.89% for potato and 60.06%, 70.81%, 85.64%, 65.03%, 60.24%, 66.02%, 88.49%, 87.89% and 86.24% for onion respectively. The highest Ky of 0.98 and 0.85 was attained at 50% CWR for potato and onion respectively and the lowest was 100% CWR for both crops. This show the highest yield reduction was registered under 50% CWR. The application efficiency, storage efficiency, distribution uniformity and yield response of 75% CWR is slightly low from full irrigation water level. So it is recommended to use 75% CWR for both crops in saving water as it has low yield reduction. Therefore, to implement deficit irrigation on farm participatory training should be given for application of right amount of water.
