Introduction: The intensive use of synthetic fertilizers in horticultural crops generates economic and environmental impacts, particularly in already degraded soils. Sustainable strategies are therefore required to reduce mineral fertilizer inputs without compromising crop productivity. This study evaluated the effect of an organic amendment containing Trichoderma viride immobilized on rice husk as a strategy to reduce mineral fertilization in yellow chili pepper (Capsicum baccatum L.) var. pendulum. Methods: Four treatments were evaluated in a completely randomized block design with three replications: T1 (complete fertilization with 200:66:42 kg ha⁻¹ N:P:K), T2 (135:48:21 kg ha⁻¹ N:P:K without organic amendment), T3 (135:48:21 kg ha⁻¹ N:P:K plus organic amendment at 0.5 kg plant⁻¹), and T4 (organic amendment only). Crop variables (height, chlorophyll index, root depth, fruit number, yield, and dry matter) were evaluated. Results: Full fertilization (T1) increased plant height and showed a slight tendency toward higher chlorophyll index and fruit number values. However, yields under reduced fertilization (T2 and T3) were statistically similar to T1, indicating that mineral fertilization could be reduced by 30% without significant yield penalties under the evaluated conditions. The addition of the organic amendment in T3 did not significantly increase yield compared with T2, but promoted greater dry matter allocation to leaves, stems, and roots, suggesting a potential positive effect on vegetative development. Discussion: The results indicate that reducing mineral fertilization in yellow chili pepper is feasible without compromising productivity. The incorporation of T. viride immobilized on rice husk may represent a complementary strategy for agroecological transition while promoting the recycling of agro-industrial residues. Nevertheless, because the findings derive from a single growing season, multi-year studies are required to validate these results and to assess long-term effects on soil properties, microbiota dynamics, commercial scalability, and economic viability.

En el presente trabajo se estudió la obtención de biogás con el estiércol de ganado vacuno y los residuos agroindustriales (torta de piñón, cascarilla de arroz y rumen de ganado bovino). Los biodigestores fueron botellas de plástico de 1750 ml. El biogás producido se colectó por desplazamiento de agua, en botellas calibradas de plástico de 260 ml, durante 35 días. El objetivo principal fue determinar el rendimiento óptimo de la mezcla de estiércol y residuos agroindustriales en la producción de biogás. Además de evaluar la producción de biogás generado por las mezclas de estiércol con los residuos agroindustriales. Dicho trabajo se realizó en las instalaciones de la E.E.A. El PORVENIR – INIA, ubicada en el distrito de Juan Guerra, Provincia de San Martín.
