The cape gooseberry (Physalis peruviana L.), native to the mountainous regions of South America, is widely cultivated in Colombia, the world's leading producer and exporter. Expanding its cultivation to new regions requires evaluating its adaptability and performance under technologically advanced production systems. The objective of this research was to assess the productive potential of five cape gooseberry varieties at two plant densities (27 639 and 13 861 plants∙ha-1) under greenhouse and hydroponic conditions. The experiment was set up in a randomized complete block design with a split-plot arrangement and four replications. The larger plot corresponded to planting density, and the smaller plot to varieties, with a planting pattern of 1.2 m between rows and 0.5 m between plants. Density and variety showed highly significant effects on stem diameter and plant height. Density also had significant effects on fruit weight with and without calyx, and highly significant effects on total yield and yield per plant, evaluated in seven harvests every 20 days. The Sacha variety showed the highest values for polar and equatorial fruit diameter, as well as the highest yield. The Modificada variety had the lowest values for total soluble solids. Significant effects of density on total titratable acidity 4 (TTA4) and of variety on TTA3 were observed. Vitamin C did not show significant differences between treatments. Low density resulted in shorter plants and higher yield. The Sacha variety performed best in terms of yield and fruit quality. There were no interactions between variety and density for yield, but there were interactions for plant height and fruit size.
