Este estudio de caso documenta la experiencia de la clínica de plantas de Chamis, Cajamarca, Perú, establecida en 2013 a través de un convenio entre INIA y el programa Plantwise CABI. El documento presenta cómo las clínicas de plantas representan un servicio innovador de asesoría agrícola con presencia permanente en comunidades rurales, en un contexto donde solo el 7.3% de los agricultores del país reciben asistencia técnica (4.6% en Cajamarca según CENAGRO 2012). La clínica de Chamis, ubicada a 3200 msnm y manejada por los ingenieros Marieta Cervantes Peralta y Fernando Escobal Valencia de la EEA Baños del Inca, atiende cada quince días durante la época de producción. El estudio describe cómo la clínica ha evolucionado más allá de su enfoque inicial en plantas para convertirse en una "clínica agropecuaria" que atiende consultas sobre cultivos, animales (especialmente...

Este estudio de caso documenta la experiencia de la Estación Experimental Agraria Baños del Inca de INIA en Cajamarca para hacer llegar servicios de asesoría agrícola a pequeños productores en contextos altamente desafiantes. Desde 2013, en el marco del convenio Plantwise-INIA, los doctores de plantas Ing. Fernando Escobal Valencia e Ing. Marieta Cervantes Peralta operan dos clínicas de plantas (Chamis y Chetilla), acumulando tres años de experiencia que revelan los retos de proveer servicios que satisfagan la demanda tanto de hombres como de mujeres. El documento aborda la problemática de la migración masculina rural-urbana en Cajamarca, donde las mujeres quedan a cargo de las chacras y crianzas, pero solo representan el 25% de los usuarios de las clínicas. En un contexto donde solo el 4.6% de los 329,650 productores de Cajamarca reciben asistencia técnica, el 89.3% tienen pr...

The rye (Secale cereale L.) crop shows a high potential to contribute to the sustainability of high Andean livestock because it supports the agroclimatic conditions and acid soils in the Peruvian Andes. The production of green forage, hay, and grain from the rye crop in acid soils was studied with the use of different levels of phosphorus and potassium fertilization in four local rye ecotypes (CBI-001, CSM-001, CJS-001, and CCE-001). The green forage yield (GFY) ranged from 32.35 to 53.62 t ha−1, dry matter from 6.05 to 8.56 t ha−1, and hay from 7.0 to 10.36 t ha−1; nutritional levels ranged from 9.02% to 13.56% protein and 6.50% to 7.75% ash levels, mainly with differences between ecotypes (p < 0.05). No differences existed between fertilization levels for the number of stems per plant, spikes per plant, and grains per ear (p > 0.05). Also, CBI-001 and CCE-001 were superior with 1...

Livestock production in the basins of the northern macro-region of Peru has as its primary source pastures of Lolium multiflorum L. ‘Cajamarquino ecotype’ (ryegrass CE) in monoculture, or in association with white clover Ladino variety, for feeding. The objective of this research work was the morphological characterisation, yield evaluation, and cutting time evaluation of two local genotypes (LM-58 and LM-43) of Lolium multiflorum L. in six locations. An ANOVA was performed to compare fixed effects and interaction. It was determined that the LM-58 genotype is intermediate, growing semi-erect, with a dark green colouring and 0.8 cm broadleaf, and can reach an average stem length of 46 cm, up to 1.6 cm. day−1, achieving fourth-leaf growth at 28 days under appropriate management conditions. Despite the differentiated characteristics, according to BLASTn evaluation, the ITS1 sequences ...

The productive sustainability of Pennisetum clandestinum in the Peruvian highlands was evaluated through productivity, growth and chemical composition. The effect of the nitrogen (N) rate, organic matter application, and cutting frequency on Kikuyu grass's yield, chemical composition, plant height, and growth rate was investigated. Experimentation followed a randomized block design with split plots. Multivariate analysis of variance (MANOVA) assessed differences across study factors. Applying 120 kg of N ha-1 yr-1 raised the protein yield to 3454.53 kg ha¯¹, with a crude protein (CP) content of 23.54%. Moreover, cypress (Cupressus lusitanica) trees influenced the Kikuyu biomass, producing 19,176.23 kg of dry matter (DM) ha-1 yr-1 at 8.5-11.5 m from the tree base. Organic matter enhanced Kikuyu aboveground biomass. While dry matter production showed no significant difference between 30-...

El presente documento denominado “Sistematización de experiencias de capacitaciones y asistencia técnica en el manejo sostenible de suelos a los productores agrarios de las regiones de Puno, Huancavelica, Ayacucho y Cajamarca”, realizado entre los años 2017 a 2020, describe de manera didáctica y mediante un lenguaje claro las experiencias realizadas en las comunidades sobre las técnicas de manejo y conservación de suelos en los diferentes sistemas de producción agropecuaria de la sierra de Ayacucho, Cajamarca, Huancavelica y Puno. Por ello, este documento se considera como una herramienta de consulta y motivación para los productores, técnicos, estudiantes de universidades e institutos y profesionales.
