Diseño agronómico de un sistema de riego parcelarlo para el Módulo 7 del Proyecto Chambo - Guano, Fase II, comunidad Chingazos, cantón Guano.

Abstract

The purpose of this study was to carry out the agronomic design of a parcel irrigation system for Module 7 of the Chambo-Guano Project, Phase II, Chingazos community, Guano canton. To achieve this, field capacity, permanent wilting point, bulk density, and infiltration rate were determined. Additionally, crop pattern, precipitation, crop coefficient, crop evapotranspiration, water balance, net requirements, root depth, gross irrigation depth, and the emitter were obtained. A socio-economic survey, financial evaluation, and budget for implementation were also conducted. Module 7 has the following characteristics: sandy texture, field capacity of 7.7%, permanent wilting point of 2.1%, and bulk density of 1.3 g cm-3. The existing crops include corn, lemon, strawberry, chocho, and blackberry. The net water requirement is 2.69 mm day-1, the gross irrigation depth is 23.12 mm, and the infiltration rate is 156.8 mm h-1. The calculated irrigation frequency is every seven days for 3 hours using mini-Wobbler nozzle #6. The proposed project encourages the cultivation of avocados. The family income is USD 1,739.20 per year compared to USD 92.00 without the project. The NPV is USD 181,377, IRR is 27.10%, B/C is 1.05, and PRI is 5.016 years. The investment is USD 192,797.67. It is concluded that the soil's physical parameters are suitable for micro-sprinkler irrigation. Avocado cultivation is recommended, and the gross irrigation depth is 23.12 mm every 7 days for three hours. The study demonstrated positive profitability, with an investment of USD 4,988.29 per hectare for the irrigation system installation. Competent authorities are advised to manage financial resources for the implementation of the irrigation system.
