The present investigation was carried out in the Experimental Area of Irrigation (EAI) of the UNALM- District of La Molina - Lima, at an altitude of 243.7 m.s.n.m. In this regard, the reference evapotranspiration (ETo) was estimated with the FAO Penman-Monteith method (Allen et al, 2006) from information obtained from a Davis automatic weather station and the crop evapotranspiration (ETc) of rice variety IR 71706 of duration between December 2017 to April 2018, was calculated with information obtained from a drainage lysimeter. Daily irrigation readings, variation of soil moisture and precipitation were recorded to perform the soil moisture balance and thus determine the crop evapotranspiration and obtain the values of the crop coefficient during the crop cycle. Thus the ETc was obtained, whose maximum daily value was 9.19 mm day−1 in the reproductive phase (state of spindle and flowering) and the minimum of 1.35 mm day−1 in the final stage of cultivation and an average of 5.02 mm day−1. The total ETc during the investigation was 658.23 mm for 587 tillers m−2 and an average height of 80 cm. The coefficients of the initial Kc culture, medium Kc and final Kc, varied in the range of (0.9, 1.70, 0.84) respectively.
