الملخص الإنجليزي

This research was conducted in unheated plastic house at Horticulture and Landscape Design Department, College of Agriculture & Forestry, Mosul University, during the growing season 2012-2013.

The aim of this study was to investigate the effect of magnetic water and urea spray on some physiological and chemical parameters of two lettuce cultivars in NFT culture system, transplants of two lettuce varieties (Regina dei ghiacci and Great Lakes 118) were continuously treated by three intensities of magnetic water (0 ,750 and 1500 gauss) during the experiment period and two foliar sprays of pure urea at three concentrators (0, 0.125 and 0.250 %) were applied.

Asplit-split plot system within a randomize complete block design (RCBD) with three replicates was used to carry out this experiment.

Results data could be summarized as follows the Regina dei ghiacci variety has been significantly superior in the percentage of N , K and P elements in leaves as compared with Great Lakes 118 Var.

which superior in the total solute solid percentage only.

Spraying of urea at both concentration (0.125 and 0.250 %) caused a significant increase in T.S.S and nitrogen percentage in leaves.

Mean while, using 750 guess lead to higher significant increase in the percentage of nitrogen in leaves, At the same time the interaction treatments caused apositive additional increase in many percentage as compared with the effect of single factor.
