The objective of this study was to conduct agricultural zoning of climate risk for quinoa cultivation. Data from 38 meteorological stations of the National Meteorology and Hydrology Service in Puno region were used. The zoning was based on the development of the water balance model, applying the water requirement satisfaction index (ISNA), for two levels of soil available water capacity (115 mm/m and 145 mm/m). Spatial analysis of the ETr/ETm ratio, obtained from the SARRAZON model, was carried out for each phenological stage through frequency analysis of ISNA values. These data were processed in ArcGIS10.0, using the ordinary kriging interpolation method. Once the maps were generated, they were clipped to the quinoa production zones of the region and classified as follows: for Phase I: low risk (ISNA ≥ 0.65); medium risk (0.55 < ISNA < 0.65) and high risk (ISNA ≤ 0.55), consid...

The objective of this study was to assess the effects of saponins derived from Chenopodium quinoa by-products on methane (CH4) production in a ruminal fermentation system under in vitro conditions. Additionally, the study included the analysis of short-chain fatty acids (SCFAs) and true dry matter digestibility (TDMD). The saponin extracts obtained from three quinoa varieties were Altiplano (AS), Quillahuaman (QS), and Salcedo (SS), and were tested at six different doses (0, 0.2, 0.4, 0.6, 0.8, and 1.0mg/mL) each. Rumen fluid was obtained from two fistulated Junín breed sheep, with alfalfa hay (AH) and a 1:1 mixture of maize and bran (MB) was used as basal substrates. The data were processed in a completely randomized design and replicated three times. The CH4 per dry matter (mL/g DM), after 24h of incubation significantly decreased, acetate molar concentration decreased (p<0.05) with A...

RESUMEN El presente trabajo estudió las isotermas de adsorción a 25 °C de harina de tres variedades de quinua (Chenopodium quinoa Willd.): INIA Salcedo (IS), Pasankalla Roja (PR) y Negra Collana (NC) sin maltear y malteada, así como su vida útil. Las isotermas fueron determinadas colocando 2g de muestra en un analizador de actividad de agua. Se programaron lecturas de 0.05 a 0.90 de actividad de agua, para construir las isotermas y la humedad inicial se determinó por el método gravimétrico. Los datos experimentales fueron ajustados con los modelos matemáticos de GAB, BET, Henderson, Halsey y Oswin. La bondad del ajuste se evaluó con el coeficiente de regresión y el porcentaje de error medio relativo (%E). Como resultado se verificó que el modelo de GAB y Oswin presentaron un buen ajuste de los datos experimentales con un coeficiente de correlación superior a 0.98 y un %E men...
