(a) Data are ad:lpted from Haas (13)<br />
(b) For some crops. the concentrations givcn Ill:ly e:w;ceed the overall salinity tolerance of that crop and cause some yield<br />
reduction before chloride ion lQ.>:icities. Values given arc for the ma.>:iTnwn concentration in the irrigation water. The<br />
values were derived from saturation elttract data (ECe) by the following relationship: saturation extraction<br />
concentration = I j water conccnlIation.<br />
(c) The maltimum permissible valucs apply only to surface irrigated crops. Sprinkler irrigation may cause e.>:cessive<br />
leaf bum at values far below these, (see Table 3·10).<br />
