The management of late blight (Phytophthora infestans) in the potato crop is a constraint for growers in Colombia, and it is important to seek alternatives for its control. Therefore, the objective of this study was to evaluate a decision support system (DSS) for the management of the disease in three potato varieties. For this purpose, an experiment was established in the municipality of Mosquera, Cundinamarca (Colombia), with three treatments (DSS management [T1], positive control [T2] and negative control [T3]) in a crop cycle with three cultivars (cv Diacol Capiro, cv Ica Única and cv Suprema). Yield variables, late blight severity, area under the disease progress curve (AUDPC) and its relative area (rAUDPC) were measured. The use of DSS (T1) resulted in yields comparable to those obtained with strictly chemical management (T2). There were statistically significant differences (p &l...

Water is fundamental for the development of life, its care and good management being a responsibility that we must have when we use it. Therefore, the objective of this study was to evaluate the effects of two irrigation techniques on the yield and volume of water applied to the potato crop. For this, an experiment was established under two irrigation alternatives (proposed and traditional) in a potato cycle of the Tuquereña variety, in the municipality of Toca, department of Boyacá (Colombia). Where properties of each irrigation proposal were measured (uniformity of application, volume of water applied, irrigation efficiency) and at the end of the crop cycle, information on crop performance was taken. Statistically significant differences (p < 0.05) were presented when the proposed irrigation system was used, increasing production by 3 tons per hectare and reducing the volume of wa...
