The high Andean grass Jarava ichu (Poaceae) plays a vital role in water regulation and aquifer recharge. However, its limited use is often linked to forest fires, highlighting the need for sustainable alternatives. Therefore, this study aims to explore the valorization of ichu as a substratefor the cultivation of Pleurotus spp. (P. citrinopileatus, P. djamor and P. ostreatus) and to evaluate the potential of the residual substrate as a biofertilizer, offering an ecological alternative to grassland burning in the Peruvian Andes. Samples of ichu from the district of Tomás (Lima, Peru) were used as culture substrate, analyzing productivity indicators such as crop cycle (CC), biological efficiency (EB) and production rate (PR), together with the nutritional profile of the fungi and the chemical properties of the residual substrate. The results showed an average biological efficiency of 19.8%, with no significant differences (p>0.05) in CC, EB or PR among the species, confirming the viability of ichu as a substrate. The fungi presented a high protein content (24.1-30.41% on a dry basis), highlighting its nutritional value. In addition, the residual substrate exhibited elevated levels of phosphorus (795.9-1296.9 ppm) and potassium (253.1-291.3 ppm) compared to raw ichu (0.11-7.77 ppm for both nutrients). Germination tests on radish seeds showed rates between 80% and 100%, without inhibition, supporting its potential as a biofertilizer. This study demonstrates the doublé potential of ichu as a substrate for the sustainable production of edible mushrooms of high nutritional value and as a source of biofertilizers

El libro de resúmenes del I Congreso Peruano de Extensión Agropecuaria reúne 55 contribuciones: 26 trabajos de investigación y 29 casos de éxito, que evidencian los avances de este campo en el país. Las investigaciones se organizan en cinco ejes temáticos que sintetizan la evolución, políticas y retos de la extensión agropecuaria en el Perú; el rol de la academia en la formación y profesionalización de extensionistas; las metodologías y herramientas que potencian la innovación y el desarrollo rural; la participación del sector privado y la cooperación internacional en la construcción de ecosistemas colaborativos; y la transformación digital, con sus oportunidades para democratizar el acceso a la información y fortalecer la toma de decisiones en el territorio. Asimismo, los casos de éxito, que demuestran el impacto positivo de la extensión en el sector agropecuario rural, se centran en tres temáticas: innovación, impacto social y ambiental, y escalabilidad.
