SERVIN PALESTINA, Miguel et al. System to program and schedule the irrigation of crops in real time. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.2, pp.423-430. ISSN 2007-0934.

The agricultural activity consumes more than 70% of the water available worldwide, it is considered a great consumer of water resources, this is due to the waste of water that is presented, even in technical systems since the water requirements of crops are unknown. This study focuses on irrigation scheduling, which is a technique that determines the quantity of water and the time when crops are to be irrigated, is a fundamental instrument to achieve a better use of water. It is regularly performed without technical support based solely on the users experience, which is why it is necessary to systematize and disseminate the available techniques to perform it in an appropriate way. The objective of this research was to develop an online system for irrigation users in the state of Zacatecas to estimate the water demands of crops (garlic, pepper, beans and maize) and program their irrigation in real time. This system solves the task by means of a climatic water balance and the use of climatic data obtained from the network of 36 automated agroclimatic stations distributed in the state of Zacatecas. What allows to estimate the consumption of water over time, and to determine the calendar of irrigation of the crops; the program runs via the internet and was encoded in PHP language which, along with HTML, allows you to create dynamic web sites.

Palavras-chave : crops; evapotranspiration; water-soil; water balance; weather stations.
