GONZALEZ ROBAINA, Felicita et al. A database on water requirements. Rev Cie Téc Agr [online]. 2012, vol.21, n.2, pp.42-47. ISSN 2071-0054.

The management and accessibility to information on water regime of the main agricultural crops is of great economic and social impact since it allows the definition of the role of water yield and water productivity as efficient tools in the planning, design and operation of supply water to crops. This paper is aimed at obtaining from the collection and tabulation of experimental results available at the IAgric, a database on water requirements of some crops of agricultural interest. The database includes the experimental data from 1971 to 2009, more than 22 crops, five soil types, different irrigation techniques and a wide range of irrigation treatments. And the variables: evaporation, water consumption, yields, amounts of irrigations, water applied per irrigation, rainfall reported, usable rain. This database will determine later in crops of interest potential production, agricultural productivity and water yield response factor as an expression of water-yield performance, contributing to the development of strategies that respond to problem of water scarcity and food security to a lower environmental cost. The database will be placed IAgric website as part of the Advising Irrigator System all interest for users.
