AbstractIn this paper we study the balanced 4 – way mixed effects model that has one random effect interacting with one fixed effects and this interaction interacts with each of other two fixed effects as a nested repeated measures model .
As studies of water in the present time of the basic necessities, which must be carried out, the fact that the quality of water has become specific agricultural production, both quantitatively and qualitatively, in addition, the use of the kinds of poor water is reflected not only damage to crop productivity but may lie in the land itself so that result, over the years to a deterioration in the overall qualities good soil and the emergence of the problems of salinization and alkalinity and toxin crops planted.
From here we discussed the application of data on agricultural the experience of the study as well as types or levels of different fertilization to reduce existing salinity in the waters of subterranean wells for three sites in the Zubayr region and the impact on the production rate recipes growth)the level of higher plant) a crop also targeted the experience in the same time creating overlap between the quality of water used, as well as chemical fertilization and their impact on production quantity and quality through the application of the model of repeated measurements.
