| Abstract | ||
| A field investigation was carried out, during 1997 and 1998 seasons. Eight soil locations were chosen, irrigated for long time with agriculture drainage water, or drainage water mixed with waste water, along drain No.4 ( 42 Km), in comparsion with two locations of soils, which were irrigated with fresh water. The obtained results could be summarized as follows: Using drainage water, or mixed with waste water caused appreciable reduction in seed cotton yield and some yield characters. Applying drainage water for irrigation, led to decrease in rice grain yield and yield components, in comparison with fresh water use for irrigation. Results indicated that, significant negative correlation was found, between salinity of irrigation water used and grain yield of rice crop. Applying low quality irrigation water for wheat crop production, caused reduction in grain yield, and 1000 grain weight, in comparison with fresh water applying. There were reduction in fresh yield weight of clover crop (ton/fed), at the two cuttings of clover, as a result of applying drainage water only, or mixed with waste water, in comparison with that in the case of using fresh water for irrigation. | ||
