Propiciar el desarrollo científico tecnológico de sistemas integrales de Ingeniería Agrícola que viabilicen la implementación armónica de tecnologías de riego y drenaje, mecanización, energía, postcosecha, conservación ambiental y construcciones rurales sobre la base del uso sostenible de los recursos naturales, para contribuir a la seguridad alimentaria del país.

One of the problems in our agriculture at the present time is the lack of upgrade of the indexes of consumption of fuel for the different agricultural works, of there the necessity on the part of the agricultural entities of the Ministry of the Agriculture to upgrade the same ones under the real conditions of production. For that arouses the necessity of the realization of a research related w ...

Artificial neural networks in the reference evapotranspiration estimation

Méndez-Jocik, Alberto A. et al. [artificialintelligence.]

Artificial neural networks (ANN) is a powerful modeling tool based on the principles of artificial intelligence suitable for the analysis of complex ecosystems which combined with remote sensing techniques can provide answers where mathematical and physical equations lose their scope. In this first analysis, seven variables were included, surface temperature and emissivity as radiometric produ ...

Adaptation of water extraction levels in Güira de Melena municipality

Cisneros-Zayas, Enrique et al. [consumptionindex.]

The Güira de Melena municipality is located on a coastal aquifer where in the last years the saltwater intrusion has been intensified among other causes, for the over exploitation wells for irrigation. The present work has as objective to show that starting from a correct adaptation of the equipment pumping in three municipality zone; decrease the flows extract of the aquifer, minimizing the s ...

The research was carried out in Ceballos Agroindustrial Enterprise of Ciego de Ávila. Different models of drippers were studied with the objective of evaluating self - compensating and non - compensating emitters in microirrigation systems in Ciego of Avila. In the mechanical and hydraulic evaluation of the emitters, the pressure-flow rate curve was experimentally determined for the models eva ...
