12 ~ plots on irrigation levels 4-6 of 75 percent of the fresh plots. This ~ ~ reduction was about the same as last year (Figure 2). ~ The yield data also indicate a yield reduction on the salty plots. The grain yield (Jigures 3 and 4) on irrigation levels 4-6 for the salty plots was 76 percent of the fresh plots. The dry matter yield on the salty plots was 77 percent of the fresh plots. In 1980 the average yield on the salty plots was about 80 percent of the fresh plots. The barley yield data also show a yield reduction on the salty plot compared to the fresh plot. The grain yields (Figures 4 and 5) on the salty plots, irrigation levels 4-6, were 75 percent df the fresh plots. The dry matter yields on the salty plots were 70 percent of the fresh plots. In 1980 the salty plots yielded about 80 percent' of the fresh plots. It is rather strange that the yield reduction on barley was greater than wheat ,because barley is expected to be the most salt tolerant. It is also apparent that there was an effect of irrigation level on the yield reduction. The ratio of yield of barley on the salty to fresh plots was 0.56, 0.68, 0.67, 0.90 for irrigation levels 3, 4, 5, and 6, respectively. Thus for low irrigation with no leaching like level' 3, there was more yield reduction than for the high irrigation levels, like level 6, where there was some leaching. It is also interesting to note that the yield on irrigation level 6 for the fresh plot was 0.92 that of water levelS, whereas for the salty plot the yield on irrigation level 6 was l.22 that of irrigation levelS. Thus, leaching improved yields on the salty plot but decreased yields on the fresh plot. The same general trends were found for the potatoes.
