DEFICIT IRRIGATION OF GRAIN AND OILSEED CROPS

摘要

Deficit irrigation is an alternative to full irrigation where water is applied to crops in amounts that are anticipated to support transpiration at less than the maximum potential level. Under such circumstances, one might expect crop growth and yieldto be less than that achieved under full irrigation. However, profitable production of certain crops can be achieved using deficit irrigation with considerable savings in water used or when the water supply is constrained. Deficit irrigation of field crops has been discussed in several research papers and reviews (English and Nuss, 1982; Musick and Walker, 1987; English et al., 1990; Musick, 1994; Fereres and Soriano, 2007; and Geerts and Raes, 2009).
