Abstract
El cultivo de fresa desempeña un papel significativo en el panorama agrícola del Perú, no solo en términos económicos, sino también sociales y ambientales. Sin embargo, las prácticas convencionales de manejo han generado preocupaciones ambientales debido al uso excesivo de agroquímicos, por ello, este estudio propone un enfoque orgánico para la producción de fresas, garantizando la sostenibilidad del sistema agrícola de producción sin comprometer la calidad, el rendimiento y los recursos ambientales. El objetivo principal de esta investigación fue evaluar el efecto de la inoculación microbiana utilizando Trichoderma sp. y Pseudomonas sp., y la aplicación de enmiendas orgánicas como compost, estiércol y rastrojos de palto en plántulas de fresa del cultivar comercial "San Andreas" en el Valle de Huaral. El experimento en campo consistió en 12 tratamientos, basados en la combinación de inoculaciones y enmiendas, evaluándose parámetros biométricos y de rendimiento del cultivo. Los resultados obtenidos revelaron beneficios significativos de la coinoculación de Trichoderma sp. y Pseudomonas sp., logrando un alto porcentaje de prendimiento, además de obtener mejoras en parámetros área foliar, peso fresco de planta y un mayor número de frutos por unidad experimental. Se observo que los tratamientos sin inoculación de microorganismos mostraron mayor precocidad en los días de fructificación. Asimismo, la aplicación de compost mostró resultados significativos incrementando el número de hojas, altura de planta y peso seco aéreo; dimensiones de fruto, peso de fruto y rendimiento; asimismo también se notó una mayor precocidad en los días de fructificación Estos resultados muestran la capacidad de las tecnologías sustentables, como la inoculación microbiana y el uso de enmiendas orgánicas, para mejorar la producción y calidad de las fresas.
Strawberry cultivation plays a significant role in Peru's agricultural landscape, not only in economic, but also in social and environmental terms. However, conventional management practices have generated environmental concerns due to the excessive use of agrochemicals; therefore, this study proposes an organic approach to strawberry production, ensuring the sustainability of the agricultural production system without compromising quality, yield and environmental resources. The main objective of this research was to evaluate the effect of microbial inoculation using Trichoderma sp. and Pseudomonas sp. and the application of organic amendments such as compost, manure and avocado stubble on strawberry seedlings of the commercial cultivar “San Andreas” in the Huaral Valley. The field experiment consisted of 12 treatments, based on the combination of inoculations and amendments, evaluating biometric parameters and crop yield. The results obtained revealed significant benefits from the co-inoculation of Trichoderma sp. and Pseudomonas sp., achieving a high percentage of yield, in addition to obtaining improvements in leaf area parameters, fresh weight of the plant and a greater number of fruits per experimental unit. It was observed that the treatments without inoculation of microorganisms showed greater precocity in the days of fruiting. Likewise, the application of compost showed significant results in increasing the number of leaves, plant height and aerial dry weight; fruit dimensions, fruit weight and yield; as well as a greater precocity in the days of fruiting. These results show the capacity of sustainable technologies, such as microbial inoculation and the use of organic amendments, to improve the production and quality of strawberries.
