The research paper entitled "ESTIMATED STOCK CARBON IN FOUR SYSTEMS LAND USE (Theobroma cacao, Coffea arabica L, Bactris gasipaes Kunth and secondary forest) IN THE REGION SAN MARTIN" aimed evaluate and study the capacity carbon storage in tour land use systems (cocoa, coffee, peach palm and secondary forest) located in tour districts in the San Martin region (Campanilla, Chirapa, Pongo Caynarachi and Pucacaca). To determine the carbon content of three living biomass , litter and soil carbon components were evaluated for analysis allometric formulas established for each system were used , resulting in the secondary forest (Ojos de Agua) is located in Pucacaca more total carbon stock with 558,37 t.ha ·1 highly outperforming all other systems studied. Among the components evaluated in the tour systems, the biomass area which provides greater amount of carbon stored in the secondary forest...

Se evaluó el soporte de las ramas de la higuerilla (Ricinus communis L.) en el rendimiento del frejol (Phaseolus vulgaris L.) variedad Huasca Poroto en las comunidades nativas de Alto Shamboyacu y Chunchiwi, región San Martín. Se utilizó el Diseño de Bloques Completamente al Azar, con cuatro tratamientos y tres bloques. Los tratamientos utilizados fueron: T0 (frejol con maíz, testigo), T1 (todas las ramas de higuerilla sin podar asociado con frejol), el T2 (higuerilla podada y la formación de dos ramas de higuerilla asociado con frejol) y T3 (higuerilla podada y la formación de tres ramas de higuerilla asociado con frejol). Las variables evaluadas en ambas comunidades fueron: área foliar (cm2), longitud de vaina (cm), número de vainas por planta, altura de planta (m), número de semillas por vaina, peso promedio de semillas (g), rendimiento (kg/ha-1) y análisis eco...

The support of the branches of the higuerilla tree (Ricinus communis L.) is evaluated in its ability to promote the yield of the bean variety Huasca Poroto (Phaseolus vulgaris L.) in the native communities of Alto Shamboyacu and Chunchiwi, San Martin region. We used the Randomized Block Design, with four treatments and three blocks. The treatments used were: T0 (bean with corn, control), T1 (all unpruned huiguerilla branches associated with bean), T2 (higuerilla pruned and the formation of two higuerilla branches associated with bean) and T3 (higuerilla pruned and the formation of three higuerilla branches associated with bean). The indicators used in both communities were: leaf area (cm2), pod length (cm), number of pods per plant, plant height (m), number of seeds per pod, average seed weight (g), yield (kg/ha-1) and economic analysis. In both communities, the treatment T3 provided mor...
