In this research work, soil moisture, evapotranspiration and biometric growth parameters of two varieties of sweet potato under conditions of water deficit were related. The irrigation method that was applied was drip irrigation in two ways; Normal irrigation with 100% sheet (control) and partial root drying irrigation (SPR) with three different treatments (start of treatment), at 23, 33 and 45 days after sowing, in the cultivation of two varieties sweet potato: Huambachero and Paramonguino. Research carried out in the experimental plot of the Department of Water Resources of the Faculty of Agricultural Engineering of La Molina National Agrarian University (UNALM), with coordinates WGS 84 / UTM ZONE 18L E 287603.46 and N 8663772.82, with an altitude of 235 meters above sea level. A The sweet potato plants with partial irrigation treatment were watered alternately covering approximately 50% of the root zone, on the other hand, the application of irrigation in the sweet potato plants with normal irrigation covered 100% of the root zone. The irrigation sheet was determined according to the evapotranspiration of the type A tank, located in the experimental plot of the Department of Water Resources Partial irrigation began according to the treatments at 23, 33 and 45 days after sowing, watered with a frequency of 2 days, until 135 days after sowing, where irrigation was stopped The development of the stem, root and leaf area was monitored throughout its phenological stage of the crop, likewise data on humidity and evapotranspiration were taken, with the data obtained it was related between the variables and equations were obtained based on humidity (water consumption), the ETO and the days after sowing. With the equations obtained, we can quantify the biometric variables at any moment of the phenological stage of the sweet potato crop. A good correlation was found between the biometric variables of the crop with soil moisture and soil evapotranspiration, where an R2 greater than 0.85 was obtained in all treatments and in the two varieties of sweet potato. The yields in the Huambachero variety were the following: Control: 42.1 t / ha, at 23 days: 37.4 t / ha, at 33 days: 32.7 t / ha and at 45 days: 35.1 t / ha iv The average length of the development of the stem were the following: Control: 150.5 cm, at 23 days: 96.5cm, at 33 days: 114.15cm and at 45 days: 140.9cm The average area of the vegetation cover were the following: Control: 2697.4403cm2, at 23 days: 1987.9474cm2, at 33 days: 2126.1505cm2 and at 45 days: 2540.7681cm2 The yields in the Paramonguino variety were the following: Control: 39.2 t / ha, at 23 days 30.0 t / ha, at 33 days 31.4 t / ha and at 45 days 32.6 t / ha The average length of the stem development were the following: Control: 208.9cm, at 23 days: 162.2cm, at 33 days: 170.7cm and at 45 days: 193.9cm The average area of the vegetation cover were the following: Control: 3549.0028cm2, at 23 days: 2533.7867 cm2, at 33 days: 2753.0211 cm2 and at 45 days: 2776.6779 cm2 The application of water in the sweetpotato crop for both varieties was: 5368.9 m3/ha in the control, 3185.54 m3/ha in the treatment of 23 days, 3429.47 m3ha-1 in the treatment of 33 days and 3713.26 m3/ha The results indicate that the control and the treatments with partial irrigation show different biometric parameters and water productivity, without having a significant difference between the treatments, with the 23 days treatment showing higher water productivity, this being an alternative for applying partial irrigation.
