| Abstract | ||
| A field experiment was carried out at the fields of Kerbala government, during the growing seasons of 2008-2009 and 2009-2010. The aim of this experiment was to determine the influence of saline water on some growth characteristics and yield of three broad bean cultivars. The experiment was arranged as a split–plot with a randomized complete block design .Saline water included 4.7 and 7.8 ds.m-1for the first season and 4.3 and 7.6 ds.m-1for the second season. Whereas, the controls level of salinity were 1.8 and 1.7 ds.m-1 (river water) for two seasons respectively , arranged in the main plots. Local cv , Luz De Otono cv and Zaina SGARAVATI cv arranged in the sub plots . The Results showed that Irrigation with saline water significantly reduced plant growth , chlorophyll content, yield and its components in comparison to the control .However, the yield considerably was decreased about 65.78 and 61.77% for two seasons respectively in treatment received saline water more than 4.7 ds.m-1 in contrast to the control .The Luz De Otono cv and Zaina cv gave the highest seed yield in all treatments especially with irrigation by river water 5681 and 5406 kg/h respectively for the first season and 5942and 5673 kg/ha respectively for the second season. The highest percentage of determination coefficient with seeds yield was obtained from number of pods per plant in both seasons .According to the results it can be recommend to grow Luz De Otono cv and Zaina cv and using a number of pods per plant as a best selection indicator for high seeds yield under saline water irrigation .Also we can use saline water for irrigation with electrical conductivity not more than 4.7 ds.m-1 with decreasing the yield not exceeded than 18.06 % . | ||
