This study evaluated potato (Solanum tuberosum L.) productionin the Central Highlands of Peru through theapplication of five types of fermented solid composts,compared with conventional treatments and a control.The study was conducted in Huancayo at 3300 m abovesea level, using composts made from cattle and llamamanure, barley straw, ash, urea, and, in one case, cellu-lolytic bacteria. The composts were applied in two doses (5 and 10MT ha⁻¹), and agronomic variables such as fresh weight of total,marketable, non-marketable, and damaged tubers were evaluated.In addition, an economic analysis was performed using the partialbudget method. The results indicated that composts 1, 2, and 5 presentedthe best agricultural and economic yields. The 10 MT ha⁻¹dose showed greater efficacy in terms of total and marketable yield.Economically, all composts outperformed chemical fertilizer at the 5MT ha⁻¹ dose, while at 10 MT ha⁻¹, composts 1 and 5 stood out fortheir high benefit/cost ratio. It is concluded that the use of compostrepresents an ecologically and economically viable alternative for reducingthe use of chemical fertilizers in potato cultivation.
