Potato is grown in winter months under irrigation in Odisha. The crop has a high water requirement for obtaining good yield. On the other hand, excess irrigation reduces yield and increases production costs. In the present study to assess the effects of irrigation and mulching in potato production, plant emergence and number of shoots per plant were not affected by irrigation and mulching levels. Plant height and number of leaves were significantly affected by the treatments. Frequent irrigation at 30 mm CPE yielded maximum 22.632 t ha-1 of total tubers and 18.006 t ha-1 of marketable tubers. Water use efficiency was low (39.9 kg ha-mm-1) at high irrigation frequency and high (48.8 kg ha-mm-1) at low irrigation frequency. Irrigation at 35 mm CPE resulted in maximum total return (`140001), net return (`71853) and cost benefit ratio (2.03).
