Con el propósito de determinar los coeficientes del cultivo para el requerimiento hídrico y la influencia en los parámetros biométricos mediante imágenes captadas con drone, lisímetros de drenaje y métodos indirectos para el cultivo de papa Solanumspp en Riobamba – Ecuador, se compararon los métodos: lisímetro de drenaje, tanque de evaporación tipo A, fórmula de FAO Penman Monteith, y ortofotos captadas con drone. El estudio se realizó en los predios del Centro Experimental del Riego de la Escuela Superior Politécnica de Chimborazo del cantón Riobamba, provincia de Chimborazo, se utilizó tres estaciones agrometeorológicas digitales completas; se instalaron 3 lisímetros de drenaje. Para medir la humedad del suelo se utilizaron tensiómetros ubicados en la zona radicular a 15 - 30 y 45 cm de profundidad. Para la implementación de la investigación en campo se utilizó u...

In order to determine the cultivation coefficients for the water requirement and the influence on the biometric parameters using images captured with drone, drainage lysimeters and indirect methods for the cultivation of potato Solanumspp in Riobamba - Ecuador, the methods were compared: drainage, evaporation tank type A, FAO Penman Monteith formula, and drone-captured orthophotos. The study was carried out on the premises of the Experimental Irrigation Center of the Escuela Superior Politécnica de Chimborazo in the Riobamba canton, Chimborazo province. Three complete digital agrometeorological stations were used; 3 drainage lysimeters were installed. Tensiometers located in the root zone at 15 - 30 and 45 cm depth were used to measure soil moisture. For the implementation of the field research, a completely randomized block design with three treatments was used (T1 = application of the...

The study aimed to create a geospatial model to identify agroecologically and economically viable zones for the main agro-export crops in the Piura hydrographic unit. Utilizing a Geographic Information System (GIS) and considering the bio-physical requirements of the crops, the research sought to delineate areas with high aptitude from both agroecological and socio-economic perspectives. Following the FAO's agroecological zoning methodology, various layers of spatial information were overlaid to define areas with specific suitability levels. Data were collected and analyzed from governmental sources such as SENAMHI, the Ministry of Agriculture, and the Regional Government of Piura to identify zones most optimal for each crop, closely approximating reality. The process included developing a Cartographic Model using the ArcGIS Model Builder tool, simplifying the creation of agroecological ...

This study investigates the spatial and temporal variation of the rainy season on the slopes of Lake Titicaca by analyzing rainfall series extracted from the gridded database PISCOp V2.1 and 18 meteorological stations within the study area. The onset and end of the wet season from 1981 to 2012 were evaluated using gridded data, which were then validated with recorded rainfall data and performance statistical indicators. This methodology allowed the determination of the onset and end of the rainy season for each hydrological year of the study period, and the calculation of metrics such as rainy days, wet season rainfall, and rainfall intensity. The resulting time series were subjected to trend analysis, revealing that, in general, they did not exhibit statistically significant trends. This conclusion was also supported by the trend analysis of the series derived from the gridded data. The...
