Partial root irrigation or Partial Root Drying (PRD) is a successful technique that saves water in the genus Capsicum cultivated outdoors and in greenhouses. The objective of this experiment was to determine the effect of PRD on yield and fruit quality of Capsicum baccatum L.var pendulum and Capsicum chinense (escabeche chili and panca chili, respectively) cultivated in a subtropical desert life zone5 (dd-S). The statistical model was factorial in split plots with two factors: type of irrigation (partial root drying - PRD, complete irrigation - CI) and crop variety. Frequency and time of irrigation was managed by a local farmer and controlled by the researcher, taking into account the limitations in water distribution and availability in the valley. Irrigation took place with an average frequency of 7 days in both systems. Agronomic and flow measurements were done in the 2013 (first cropping season: transplant) and 2014 (second cropping season: regrowth after pruning) seasons. Parameters such as yield, fruit fresh weight, fruit length and fruit thickness did not show statistical differences between treatments; in contrast, plant height, fruit diameter and dry weight of panca chili and fruit diameter of escabeche chili showed significant reduction. PRD allowed 22% and 30% of water saving in escabeche and panca, respectively, while irrigation water use efficient (IWUE) reached 19% and 47% in 2013 and 2014, respectively. The increased IWUE demonstrated the water saving capacity of PRD for Capsicum production in the Mala valley6, indicating the potential of this technique to improve crop production of smallholders in this region prone to limitations in the supply of irrigation water.
