El trabajo de investigación se llevó a cabo con la finalidad de evaluar el efecto del sulfato de cobre pentahidratado y proteinato de cobre sobre la incidencia de Cercospora coffeicola Berk & Cooke causante de la mancha de hierro en plantones de café, variedad Catimor a nivel de vivero y su respectivo análisis económico. Las plantas de café de la variedad Catimor, se inocularon en vivero, dos días después del trasplante con una solución preparada e infectada con Cercospora caffeícola BERK & COOKE. Las plantas inoculadas fueron asperjadas cada 15 días con sulfato de cobre pentahidratado y Proteinato de cobre, con dosis de aplicación al 1, 2 y 3 % respectivamente. Los parámetros evaluados de importancia fueron la incidencia de la enfermedad en la planta y el índice de rentabilidad. Los otros parámetros se consideraron secundarios, pero nos da a conocer cómo influye la enfer...

Potato (Solanum tuberosum L.) is a key staple crop in the Peruvian Andes, but its productivity is threatened by fungal pathogens such as Rhizoctonia solani and Alternaria alternata. In this study, 71 native bacterial strains (39 from phyllosphere and 32 from rhizosphere) were isolated from potato plants across five agroecological zones of Peru and characterized for their plant growth-promoting (PGPR) and antagonistic traits. Actinomycetes demonstrated broader enzymatic profiles, with 2ACPP4 and 2ACPP8 showing high proteolytic (68.4%, 63.4%), lipolytic (59.5%, 60.6%), chitinolytic (32.7%, 35.5%) and amylolytic activity (76.3%, 71.5%). Strain 5ACPP5 (Streptomyces decoyicus) produced 42.8% chitinase and solubilized both dicalcium (120.6%) and tricalcium phosphate (122.3%). The highest IAA production was recorded in Bacillus strain 2BPP8 (95.4 µg/mL), while 5ACPP6 was the highest among Acti...

El INIA a través de la Dirección de Supervisión y Monitoreo en las Estaciones Experimentales Agrarias (DSME) viene ejecutando el proyecto de inversión “Mejoramiento de los Servicios de Investigación y Transferencia de Tecnología Agraria en la Estación Experimental Agraria El Chira, Marcavelica, del distrito de Marcavelica - provincia de Sullana - departamento de Piura” con CUI N° 2472190, el cual tiene entre sus actividades la implementación de buenas prácticas agrícolas con enfoque especial en el control biológico de fitopatógenos. En este contexto, se ha elaborado esta guía técnica titulada “Uso de Trichoderma spp. en plantaciones de banano y plátano”, con la finalidad de proporcionar información relevante y prioritaria sobre el uso del controlador biológico “Trichoderma” en éstos importantes cultivos tropicales. Asimismo, ésta guía técnica contribuye ...

Neltuma pallida (algarrobo) is a keystone species of the Peruvian dry forest whose persistence is threatened by overexploitation and habitat degradation, making its conservation and genetic improvement a national priority. This study aimed to identify outstanding phenotypes of N. pallida through phenotypic characterization in the regions of Piura and Tumbes in northern Peru. A stratified random sampling design was applied, establishing forest plots in 13 localities and evaluating 631 adult individuals. Dendrometric and phenotypic traits were recorded together with physiographic, climatic, and edaphic variables obtained from soil analyses and geographic information systems. Phenotypic differentiation among populations was assessed using the index PST, which quantifies between- and within-population variance components. High morphological variability was detected across populations, with s...

Potato (Solanum tuberosum L.) is the third most important food crop worldwide and a cornerstone of food security across the Andean region. However, its production is increasingly threatened by the potato psyllid Bactericera cockerelli (Šulc), the vector of Candidatus Liberibacter solanacearum, the causal agent of the purple-top complex associated with zebra chip disease, which severely reduces both tuber yield and quality. This study was conducted from September 2024 to February 2025 in the province of Huancabamba, Peru, to evaluate the efficacy of biological and chemical control agents against B. cockerelli under field conditions. A randomized complete block design was implemented with five treatments and four replicates, totaling 20 experimental units, each consisting of 20 potato plants (S. tuberosum L.), of which 10 plants were evaluated. Treatments included an untreated control (T0...

El Ministerio de Desarrollo Agrario y Riego (MIDAGRI), a través del Instituto Nacional de Innovación Agraria (INIA), pone a disposición de los productores, técnicos, conservacionistas, profesionales e investigadores, la presente guía "Guía técnica de cultivos hidropónicos". El documento tiene como finalidad orientar de una manera práctica a la población peruana en el uso de la hidroponía como una técnica de producción agrícola para contribuir con la seguridad alimentaria; además de promoverla como una alternativa de emprendimiento.

Mango (Mangifera indica L.) is a tropical fruit tree characterized by vigorous growth and high fruit production, making it one of Peru's main export crops. However, its extensive vegetative development requires substantial space, limiting productivity per unit area. This study evaluated the effects of rootstock and interstock combinations on agronomic traits and fruit biometrics, highlighting the potential of interstocks to modulate tree vigor in mango orchards of Peru's dry forest region. A total of 216 trees were established using 'Chulucanas' and 'Chato' as rootstocks and 'Chulucanas,' 'Chato,' 'Irwin,' and 'Julie' as interstocks, apically grafted with the 'Kent' cultivar, with a spacing of 6.0 m × 6.0 m. Tree performance was assessed after 10 years during the 2017–2019 growing seasons in Piura, Peru, under a randomized complete block design (2 × 4 factorial). The combination of t...

Mango (Mangifera indica L.) is a key fruit crop in Peru; however, its reliance on chemical fertilizers raises concerns regarding fruit quality and environmental sustainability. This study evaluated the effects of soil-applied compost and foliar-applied biol on the quality of 'Kent' mango fruits at physiological and commercial maturity stages. Conducted during the 2022–2023 season, the experiment used a 3 × 3 factorial design with compost applied at 0, 5, and 15 t/ha and biol at 0, 5, and 10%, plus a chemically fertilized control. Results revealed significant compost–biol interactions. At physiological maturity, treatments 5-10, 15-5 and 15-10 improved pulp color, soluble solids, titratable acidity, and dry matter content, achieving a desirable yellow pulp (2.0 on the scale), 9.29 °Brix, 1.23% acidity, and 20.96% dry matter—surpassing the control. At commercial maturity, these tre...
