Abstract

Soil microorganisms hold considerable promise for the development of integrated, sustainable agricultural systems. Potato (Solanum tuberosum L.) crop productivity requires nutritional strategies that optimize yield without affecting seed commercial quality. In this context, the application of specific microorganisms that improve nutrient availability and crop physiological performance represents a sustainable strategy. This study evaluated the effect of organo-mineral fertilization and inoculation with Trichoderma viride and Bacillus subtilis on seed yield and commercial quality of tubers in two potato varieties (INIA 303- Canchán and Yungay) under the agroecological conditions of the Peruvian Andes. A completely randomized design (CRD) with a 3x3x2 factorial arrangement and three replications per treatment was used, totaling 54 DUs. Three fertilization levels (0%, 50%, and 100% NPK) and three levels of microorganisms (no microorganisms, Trichoderma, Bacillus) and two potato cultivars were evaluated. Robust ANOVA (WRS2) and Sidak’s test (α = 0.05) were applied. Tuber weight per plant was higher with complete fertilization and microorganisms: m1×n3 = 2.043±0.13kg; m2×n3 = 1.928±0.13kg. The Yungay variety outperformed Canchán in all categories, with higher first-grade seed production: 21.8±1.48kg vs. 15.7±1.48kg, reaching a maximum of 27.0±3.14kg in m3×n3. No significant differences were found between treatments for PC2 and PC3 seed weights; However, there was a difference between the Yungay (PC2: 18.2±1.08kg; PC3: 13.7±0.81kg) and INIA 303-Canchán (PC2: 13.4±1.08kg; PC3: 10.7±0.81kg) varieties. It is concluded that the integration of PGPM with chemical fertility improves seed yield and quality, promoting sustainable agricultural systems in Ayacucho.
