Impacto del cambio climático en la producción y rendimiento de quinua (Chenopodium quinoa WILLd) en la Provincia de Azángaro Región del Altiplano-Puno, Perú

Abstract

This study was carried out in the province of Azángaro (Altiplano-Puno Region), with a database from the Puno Regional Agrarian Directorate, agricultural campaign 1996-1997 to 2016-2017. The purpose was to quantify the impact of variations in temperature, rainfall and relative humidity (climate change) on the production and yield of conventional quinoa. The agroclimatic parameters were provided by the National Service of Meteorology and Hydrology of Puno (Station Azangaro). The inputs used such as seed, machine hours, daily labor price and animal fertilizer were compiled from the 2012 National Agricultural Census. Using the multiple linear regression function, the impact of the variables was explained, using Stata Software version 16. The results reveal that optimal temperature and minimum precipitation had a positive impact on the yield and production of quinoa. Other factors such as machine hours and labor wages have contributed significantly to the performance of Andean grain production. Meanwhile, seed and animal fertilizer had a negative effect on the production of conventional quinoa.
