Abstract
A pot experiment was conducted on a heavy clay soil to evaluate growth performance of wheat plant to silicon additions under saline conditions. Plants were grown in pots filled with normal soil (EC=0.71 dSm-1) and irrigated with saline water (EC=4.8 dSm-1). The experiment was set up in a completely randomized block design with four treatments and three replicates. The treatments included two soil additions (S1 biochar and S2 - Silica-solubilizing bacteria) while, S3 and S4 treatments were applied as foliar applications (S3 was marine algae and S4 was potassium silicate), in addition to the control treatment (without any additions). The obtained results showed that silicon treatments by either soil additions or foliar applications could alleviate the hazard salinity stress. There were also, best noticeable exchanges in reducing both soil EC and pH and increasing both soil organic matter and storage of some available nutrients. The increments influences reflected on increasing the fresh weight and accordingly increasing the dry matter production of straw and grain yield of wheat plants. Furthermore, the percent increase in sodium concentration due to salinity was significantly reduced in plants receiving Si applications. Straw Si concentration significantly correlated positively with Straw K concentration (r=0.96) and negatively with shoot Na concentration (r=0.43). Based on these results, increased the potassium concentration and reduced uptake or translocation of sodium may be one of the possible mechanisms of increased salinity tolerance by Si application in wheat plant.
