El objetivo de la investigacion fue evaluar la relación del aporte de la agricultura familiar para el cumplimiento de los objetivos de desarrollo sostenible uno y dos al 2030, asimismo caracterizar y tipificar la agricultura familiar en los distritos de Rupa Rupa y Castillo Grande, región Huánuco. Se trabajó con una muestra de 60 fundos familiares con un nivel de investigación descriptivo y tipo cualitativo-explicativo. Se utilizó el modelo estadístico que corresponde a un diseño completamente al azar, asimismo la prueba de media DGC para determinar diferencias significativas entre los tipos de sistemas. Los resultados mostraron que la agricultura familiar aporta al cumplimiento de los objetivos de desarrollo sostenible uno y dos al 2030 en los distritos de Rupa Rupa y Castillo Grande, debido a que son sistemas integrales de producción, tipificado como un agroecosistema biodiver...

The aim of this study was to determine the growth rate and nutritional quality of Guinea grass (Panicum maximum Jacq) under a silvopastoral system with the faique tree (Acacia macracantha). The evaluation included two seasons (rainy and dry) and three treatments: (1) under the canopy of the young tree, (2) under the canopy of the medium-size tree, and (3) outside the canopy of the tree. The trees were classified according to the diameter at chest height. The growth and quality of the grass were measured by the method of cutting and separation and subsequent laboratory analysis. The growth rate ranged from 71.09 to 51.15 kg DM/ha/d, outside and inside the tree canopy, respectively, in the rainy season. Crude protein varied from 10.58, 12.79 and 13.88% (rainy season) and 8.93, 10.26 and 11.99% (dry season) outside the tree canopy, under the young tree canopy and under the middle tree canop...

The Peruvian Amazon is a geographical area with great biodiversity, where the main economic activities are agricultural crops and grazing animals. The evaluation of sustainability in production systems is based on the analysis of economic, environmental and social components, which are variable between production units or livestock farms. The classification of livestock farms based on their characteristics of similarity and differences can contribute to the most appropriate assessment of their level of sustainability. The objective of this research was to determine the level of sustainability of livestock farms in the district of Moyobamba, San Martín, Peru, based on environmental, economic and social criteria. The research was carried out from November 2018 to February 2019 with a survey of a sample of 60 livestock farms out of a population of 2220. A survey-type form and data collecti...
