Diseño agronómico del sistema de riego parcelario del Proyecto Chambo-Guano, Fase II, para el Módulo 6 en la comunidad Chingazos, cantón Guano.

Abstract

The objective of this project was to develop the agronomic design of the parcel irrigation system for the Chambo-Guano project, Phase II, for Module 6 in the Chingazos community, Guano canton. In the first instance, a diagnosis was prepared for the execution of the agronomic design. The agronomic variables that were part of the design were defined. The parcel hydraulic design and budget were developed; and finally, a socio-economic study and financial indicators were elaborated. For the location identification, a topographical survey was conducted, dividing it into three study zones (high, medium, and low), located at Latitude: 1° 37' 17.62'' and Longitude: 78° 34' 47.53'' in the Chimborazo province. The agronomic hydraulic parcel proposal was for a net irrigation area of 38.76 ha, with 131 lots; in which water and soil analyses were conducted for each lot, considering the net depths, infiltration, total water requirement; and designating sprinkler irrigation as the irrigation method. The following agronomic results were obtained: Field capacity: 7.66%, Permanent wilting point: 3.83%, Bulk density: 1.27, Usable water depth: 29.18 mm, Net depth: 18.39 mm, Gross depth: 21.63 mm. Furthermore, the total water requirement was 3.05 mm day-1, with a continuous fictitious flow of 0.35 l/s/ha. The average infiltration rate was 222.47 mm h^-1. Regarding the emitter, a mini-wobbler nozzle #6 was used, with a consumption flow of 0.07 l s-1 and a precipitation rate of 6.94 mm h-1, resulting in 3 hours of application per emitter and 4 daily shifts in the system. It is recommended to consider a fertilization plan in the locality, with recommendations in accordance to the crops. Also, to make it compatible with the presented water analyses.
