Abstract

Potato represents a strategic crop for food security in the Peruvian altiplano, standing out for its adaptation to extreme edaphoclimatic conditions. This study evaluated morphological and productive parameters of organic potato (weight, height, spatial distribution and yield) in the high Andean region of Puno, Peru, on an area of 257.35 m² with 476 plants. Significant differences (p ≤ 0.05) were found between blocks for plant height and weight per bush. The average yield was 13.59 t/ha, with a seed use efficiency of 7.34 kg of tuber produced per kilogram of seed. Planting density was 1.85 plants/m² and yield per plant reached 0.735 kg. Spatial distribution was uneven, with lower yields at the edges of the plot, possibly due to greater exposure to environmental stress. The phenological cycle lasted 148 days, with height evaluation at 84 days, flowering at 99 days and flower removal at 120 days to favor tuber thickening. It is concluded that well-managed organic agriculture allows achieving profitable potato yields under high Andean conditions, where the interaction between microclimates, plant location and agronomic management are determinant in the productivity and efficiency of the crop.
