The rational use of irrigation water and fertilizers is essential to improve farmer’s income and to preserve the environment. The application of fertilizers along with irrigation water is a recently introduced technological alternative to traditional fertilization which is meant to improve crop yields, save water and electric energy, and also to reduce operation costs of water pumping equipments. The objective of the present research was to compare two irrigation technologies: traditional (P) and improved (T), and to measure the response of maize’s yield (Zea mays) to nitrogen fertilizer applied in fertirrigation and in the traditional way.

    ABSTRACT: In Mexico, practically all conveyance systems for water irrigation are composed by a network of channels with control structures operated manually. The lack of automation often results in low irrigation efficiency. To improve water management in these systems, the government has modernized some irrigation districts with automatic structures. However, problems have emerged with the operation of these structures, causing the users to show their inconformity about the new gates. In order to solve this problem, an experimental channel was built where prototypes of hydromechanical structures were installed. This paper presents the results of the experimental channel in terms of capacity building and research on the adaptation of the automated gates to the characteristics of Mexican canals.
