<br /> <br />~, <br />(0 <br />uu <br />CJ <br /> <br />2 <br /> <br />levels were highest in the salty plots at intermediate irrigation levels <br /> <br />where no leaching had occurred. These salinity increases do not appear to <br /> <br />be sufficient to account for the yield decreases measured for traditional <br /> <br />analysis, Thus there arechemical-water-plant growth interactions that <br /> <br />are not fully understood at present. Modification of present predictive <br /> <br />methods are needed. <br /> <br />Analysis of groundwater measurements was made for the Huntington <br /> <br />and Hunter farms. There appears to be no influence of farm irrigation <br /> <br />on groundwater flow at either location. The salinity of the groundwater <br /> <br />is generally much higher than the irrigation water or the soil water <br /> <br />leaching beyond the root zone. Thus any projected effect of the irriga- <br /> <br />tion on the groundwater would cause a decrease in salinity. <br />
