Effect of Magnetic Iron and Biofertilization Treatments on Wheat (Triticum aestivum L.) Productivity under Salinity Conditions

TWO FIELD experiments were conducted at Ras-Sudr Research ….. Station, South Sinai Governorate during two successive seasons, 2011/2012 and 2012/2013 to study the effect of four levels of magnetic iron (0, 50, 100 and 150 kg /fed) and four biofertilization; control, Pseudomonas fluorescence and Rhizobium meliloti individual and mixed application on the yield parameters of wheat (Triticum aestivum L., cv. Sakha 94). Results revealed that increasing of the magnetic iron from 50 up to 150 kg /fed significantly increased all yield and yield components parameters; plant height (cm), spike length (cm), number of spikelets / spike, weight of 1000 grains (g), biological yield (kg /fed), grain yield (kg /fed) and straw yield (kg/fed) compared with the control in each growing seasons. In single inoculation Rizobium gave better result than other treatments for all yield criteria in the two growing seasons. The effect of the interaction indicates that inoculating of the Rizobium, fertilized with 100 kg magnetic iron /fed resulted in the highest yield and yield components in the two growing seasons. Interaction resulted in between magnetic iron and biofertilization resulted in higher grain protein than the control. In addition, the percentage of K, K/Na ratio, N, and grain protein of the Sakha 94 significantly increased in the two growing seasons. The analysis of the data collected during the study proved that there were statistically significant increases of wheat yield and yield components and some chemical contents due to different rates of magnetic treatments compared by the control which revealed decreases in the previously mentioned characters. Generally, the best treatments were 100 kg magnetic iron /fed and Rizobium meliloti. Both treatments were more effective in avoiding the adverse effects of soil salinity on wheat productivity compered to other treatments used.
