| Abstract |
The efficacy of pre-sowing treatment of soybean seeds with a magnetic field for 0, 15, 30, and 60 mints were studied on the natural infestation with Tetranychus urticae, Thrips tabaci, Phenacoccus solenopsis, and Bemisia tabaci. Also, plant growth parameters and yield were considered under full and half irrigation rates over two successive summer seasons of 2020 and 2021 in Egypt. Results showed a positive enhancing plant defense effect of these treatments on soybean crops with a reduction in T. urticae and other piercing-sucking insects over the two seasons. The population of T. urticae and other piercing-sucking insect pests over the two years was in a significant negative relation with seeds magnetic exposure times as well as with irrigation amount. Reduced irrigation rate did not affect crop quality parameters (i.e. plant length, No. of branches/plant, weight of pods/plant, and seeds yield). The response to seeds' different magnetic exposure times on yield quantity (i.e. carbohydrates, protein, chlorophyll, ash, and oil contents) was determined as third degree of a polynomial model. The seeds' exposure times of 15 or 30 min. were significantly higher than 0 and 60 min.
