En este trabajo evaluamos el potencial de Alnus acuminata para su uso posterior en estudios dendroclimatológicos. Se analizó una cronología de ancho de anillos para un bosque de A. acuminata en San Pedro de Saño y se relacionó el crecimiento de los árboles con los registros instrumentales de temperatura media, máxima y mínima, precipitación y horas sol de las estaciones meteorológicas de Huayao (12° 02 ́ 18.1 ̈ S - 75° 19 ́22.2 ̈ O) y Santa Ana (12° 00 ́ 15 ̈ S - 75° 13 ́ 15 ̈ O). La cronología de ancho de anillos está compuesta por 33 series de 22 árboles y cubre el período 1968-2013. El crecimiento de los árboles estuvo relacionado negativamente con la temperatura mínima mensual del mes de abril del año corriente. Se observó una relación positiva y significativa entre la cronología de crecimiento y la precipitación de la estación de Santa Ana para los ...

The rising global demand for food, including potatoes, necessitates increased crop production. To achieve higher yields, farmers frequently depend on regular applications of nitrogen and phosphate fertilizers. As people seek more environmentally friendly alternatives, biofertilizers are gaining popularity as a potential replacement for synthetic fertilizers. This study aimed to determine how Glomus iranicum affects the growth of potatoes (Solanum tuberosum L.) and the nutritional value of potato tubers when grown alongside broad beans (Vicia faba L.). An experiment was conducted using potatoes tested at five dosage levels of G. iranicum, ranging from 0 to 4 g, to see its impact on the plants and soil. Inoculation with G. iranicum produced variable results in associated potato and bean crops, with significant effects on some variables. In particular, inoculation with 3 g of G. iranicum pr...

Given the increasing pressure on natural grassland ecosystems in the Peruvian high Andes, optimizing the use of native forage species has become essential for understanding the relationship between soil characteristics and the productive potential of these plants. This study evaluated the relationship between soil properties and the produc tive potential of three native forage species: Festuca dolichophylla, Cinnagrostis vicunarum, and Jarava ichu. The research was conducted in natural grasslands in the district of Yauli, province of Yauli, department of Junin, at approximately 4000 m.a.s.l. During the dry season 2023, soil samples were collected following standardized protocols, and key soil parameters were analyzed. The nutritional characteristics of the forage species were also assessed, including dry matter content, total protein, calcium, phosphorus, in vitro organic matter digestib...
