Dataset for: Analyze the use of thresholds based on crop water stress index calculus in potato "Unica" under drip irrigation

The objective of this study was to evaluate the UNICA potato crop variety's yield relate with the threshold of Crop Water Stress Index subjected to different water stress levels and under drip of irrigation. The trial was carried out in the experimental field of National Agrarian University La Molina during the months of June-2018 to September-2018. Three treatments of irrigation moments based on the Crop Water Stress Index (CWSI) were applied for this trial: Full irrigated (T1), CWSI less than 0.4 (T2), CWSI less than 0.7 (T3).
