| Abstract | ||||
| Soil salinity and sodicity are considered two of the most import impediments to agricultural development. Also, agricultural productivities in most of arid and semiarid regions (i.g. Egypt) were threatened by the occurrence of salts. Thus, a field experiment was carried out during the winter season of 2013/2014, in new reclaimed salt affected soil at the Experimental Farm of Sahle El-Hussania Station, Agriculture Research Center, Shrakia Governorate, Egypt., to study the role of soil amendments (organic and inorganic), plant growth regulators (PGR) and amino acids to mitigate the adverse effects of saline soil on growth and productivity of wheat crop. The results can be summarized as: the available macronutrients in soil increased gradually with decreasing the salinity and the sodicity. The raised bed which was treated by the half gypsum requirements, and filled by rice straw gave the highest significantly decrease in the EC, SAR and ESP in the upper layer (0-15 cm) raised bed compared to those filled by sand or hadn’t filled. Soil amendments application caused a significant increasing in wheat growth, biological yield (grains and straw) and protein content as the following: gypsum + rice straw > gypsum + sand > gypsum alone. Foliar applications of gebbrelic acid and proline treatments showed a significant increase in growth and yield as individually or with both amendments compared the control. These increases were positively associated with increased concentration levels of gebbrelic acid and proline applications. | ||||
