Use of compost as an alternative to chemical fertilization in potatoes(Solanum tuberosum L.)
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 ca...

| Resumo: | 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. |
