The test was carried out in the experimental plot of the Faculty of Agricultural Engineering of the UNALM. The objective of the research was to evaluate the effect of partial root irrigation on the Canchan variety potato crop through surface and underground drip irrigation, quantifying the irrigation water applied, the total and commercial yield and the productivity of the crop in reference to the volume of water applied, obtained under water stress conditions at 50% ETc and 100% Etc (Each treatment included a parallel arrangement of irrigation laterals). A nutritional plan was estimated according to a projected yield of 40 tons/ha, with the dose applied by fertigation being: 160 kg/ha N, 80 kg/ha P2O5, 200 kg/ha K2O. Three treatments were evaluated in a completely randomized design: “T1: Surface irrigation with an irrigation sheet at 100% Etc”, “T2: Surface irrigation with an irrigation sheet (SPR) at 50% Etc”, “T3 : Underground irrigation with an irrigation sheet (SPR) at 50% of Etc”. With the harvested tubers, total and commercial yield was evaluated, obtaining values of 32.78 ton/ha, 24.31 ton/ha, and 24.52 ton/ha in treatments T1, T2 and T3 respectively. The partial root drying method generated high productivity values such as 26.78 and 27 kg/m3 in treatments T2 and T3, compared to treatment T1, which obtained 11.93 kg/m3. The application of SPR generated a great impact on water savings, important in areas with water resource limitations.
