Potato (Solanum tuberosum) is considered a staple in the diet of hundreds of people. In Colombia, during 2017, a production of 2.8 million tons was registered, being the variety Diacol Capiro most planted for industrial processing in the departments of Cundinamarca, Boyacá and Nariño. The crop is sensitive to water deficit and it is the most limiting factor in production, therefore, irrigation is an essential practice which is being done by spraying with low efficiency, while drip irrigation can achieve efficiencies close to 90 %. An experiment was carried out under field conditions aiming to evaluate the effect of two irrigation systems (drip vs spray) on the production, quality, and efficient use of water in the Diacol Capiro variety potato crop in the municipality of Toca, Boyacá. A completely randomized experimental design was used with 2 treatments corresponding to each irrigation system and 3 repetitions. At 28 days after sowing (das) sprouting percentage, yield and quality of tubers were measured and harvest and efficient water use was calculated for fresh tubers. Statistical differences were observed for the evaluated treatments (p <0.05) in germination and efficient use of water; other variables did not show statistical differences. With two treatments the productive potential of the variety was reached but the drip irrigation presented the best results, producing an additional 3.49 kg of fresh tubers per m3 of water used.
