Abstract
Concrete pipe lysimcters study was conducted to assess the period approaching steady-state with 13 brackish waters of various SARiw and ECjw levels and their deleterious effects in sandy clay loam (SCL) and sandy loam (SL) soils. The results showed that 45 irrigations of waters varying in EC from 2.3 to 9.4 dS m.an d SAR levels of 15, 30 and 60 (mmol L"1 ) 0 were able to change ECe from 1.6 to 8.2 dS m~l and SAR from 1.8 to 23.6 (mmol L"1 ) in SCL soil; and ECC from 1.4 to 7.4 and SAR from 1.6 to 21.8 in SL soil, respectively. If the irrigation frequency interval is to be set up after eight days on an average, the most of these soils can be safely planted in 336 days, however, this period can be prolonged considerably if the seedling establishment of each crop is done with canal water and the brackish water is used for the rest of the period. The yield of first crop of wheat was not affected in all trcatmcents when grown in brackish water treated soils.
