Popis:	Potassium is a macronutrient that can improve the growth of crops. A randomized complete block design was used to evaluate the influence of four planting densities (50,000, 41,667, 33,333, 31,250 plants ha-1) and three potassium levels (300, 250, 200 kg of K2O ha-1) on leaf area (AF), leaf area index (LAI), crop growth index (CCI) and harvest index (CI) in potato Solanum tuberosum Phureja var. Criolla Guaneña grown in an area of Botana, Altiplano de Pasto, Nariño, Colombia. All evaluations were measured every 20 days until 120 days after sowing (das), except for the IC at the end of the cycle. Analysis of variance, comparison of Tukey means (P
