The objective was the characterization of the milk producing cattle herds of the lower basin of the river Shanusi Alto Amazonas – Loreto – Peru. In the methodology, surveys were applied to 26 breeders, the descriptive statistics was used, for the typification, the K-means cluster analysis was applied. The quantitative variables: milk production 6,33 liters/cow, the price S/ 0,86/liter having in production 5 cows/herd, average of 14 has with improved pastures, the animal load of 1,8 AU / ha , the average labor force of 0,08 workers. Regarding the qualitative variables: 69,2% of births were from May to October, 96,2%, performed only one milking, 65,4% handled registration, 100% did not perform quality control, and 53,8% did has a milking parlor. Social – Educational, 50% of the owners carry out other agricultural activities, 42,3% of the owners have primary education and the workers ...

The carbon reserve in livestock herds is evaluated and its socioeconomic and environmental relationshipin the lower basin of the river Shanusi Alto Amazonas -Loreto-Peru. For the evaluation of carbonreserves, the allometric equations of theManual Determination of Total Carbon Reserves were usedin the dierent systems of land use in Peru and for the characterization of the socioeconomic and environmentalrelationships of the herds of cattle, questionnaire for on-site interviews. The maximum accumulationof carbon per herd of cattlewas 10, 07 tCO2(e)/ha and the minimum of 0, 966tCO2(e)/haat an average of 3, 66 t CO2(e)/ha, out of the 374 hectares that make up the total area of the 20 cattleherds. The simulation of carbon accumulation in 10 years at 5tCO2(e) was of 44556, 82 for the highestand the lowest of $ 21, 39. In the degree of environmental importance 60 % clean air is given, as wellas ...

En el presente trabajo de investigación se evaluaron las características morfológicas y el rendimiento de forraje verde de cuatro variedades de pasto de genero Pennisetum. Para ello, se realizaron dos evaluaciones con intervalos de corte de 45 días, distribuidos en un diseño completo al azar (DCA) unifactorial con sub-muestra con igual número de repeticiones e igual número de unidad de muestra. De acuerdo a nuestros resultados se encontró diferencias significativas (p < 0,05) entre las comparaciones de las medias las dos evaluaciones de las variables de altura de planta y grosor de tallo, excepto para las variables de número de macollos, largo y ancho de hoja (p < 0,05). Por otro lado, se observaron que durante la estación seca se retrasa el crecimiento de la planta y en consecuencia la deficiente producción de forraje. Sin embargo, para el pasto King grass verde es el que ha ...

Grain legumes in tropical areas are of great importance as a food source, especially in rural communities. Little is known about their adaptability and behavior in non-alluvial soils of the Peruvian Amazon. Our objective was to assess the agronomic behavior of cowpea varieties in non-alluvial soils. The experiment was performed in completely randomized design with four treatments and four repetitions. Each experimental unit consisted of five rows of 6m length by 0.5m between plants and 1m between rows. The variables evaluated were: plant height (cm), number of pods, pod length (cm), number of graind per pod, grain length (mm), grain width (mm), and weight of 100 seeds (g). An analysis of variance and Tukey’ test at 5% probability were used to determine significant differences between treatments. Results showed significant differences between varieties according to the evaluated variabl...

En el presente artículo se evaluaron dos métodos para estimar la disponibilidad de materia seca en pastos mixtos en la región Amazónica, Perú; concluyendo que el método de capacitancia electrónica reporto medidas promedio de materia seca en el pasto significativamente superior al método tradicional y mostró características deseables y concordantes para su uso en la actividad ganadera.

El cultivo del cacao (Theobroma cacao) en Alto Amazonas ha aumentado sus extensiones en la última década, lo cual demanda plántulas de cacao con buenas raíces. Esta demanda requiere sustratos para la producción de plantas en vivero; sin embargo, en la zona es escaso, por lo que es necesario identificar el volumen de sustrato para obtener plántulas de cacao, con el fin de establecer plantaciones con éxito. El objetivo del estudio fue evaluar el crecimiento de plántulas en vivero, usando diferentes volúmenes de sustratos. El diseño experimental correspondió a Completamente al Azar (DCA) con arreglo en parcelas divididas y dependencias fueron representadas mediante gráficos de regresión lineal y polinómica. Se utilizaron semillas pre germinadas de cacao criollo, se evaluaron a los 15, 45, 75 y 105 días de la emergencia, altura de la planta (cm), número, ancho y longitud de h...
