Agricultural industry is subjected to enormous environmental constraints, particularly due to salinity and drought. We evaluated the role of silicon (Si) in alleviating salinity and drought induced physio-hormonal changes in soybean grown in perlite. The plant growth attributes i.e., shoot length, plant fresh weight and dry weight parameters of soybean improved with elevated Si nutrition, while...

Because of increasing trend in salinization of water sources, and inevitable using non-traditional water, a research was planned to determine the tolerance range of strawberry cv. Paros to salinity and possible role of salicylic acid (SA) in ameliorating its adverse effect on plant growth. In this research, effect of different salinity levels (0, 20 and 40 mM in nutrient solution) and SA (0, 10...
