Effect of Magnetic Treatment of Water or Seeds on Germination and Productivity of Tomato Plants under Salinity Stress

Salinity is an abiotic stress that reduces the seed germination and productivity of tomatoes. Magnetic treatment has been shown to have a positive effect on germination, seedling growth, various crop species. Therefore, three experiments were conducted evaluate whether treating saline water or seeds with magnetic field can improve tomatoes (Solanum lycopersicum) under salinity stress. To growth in response field, two laboratory carried out by passing four solutions NaCl (0, 5, 10, 15 dS/m) through (3.5–136 mT) exposing tomato same for 20 min before sowing. In greenhouse experiment, plants irrigated different magnetically-treated untreated plant growth. improved percentage, speed (lower mean time germination), length dry weight experiments, especially 5 10 dS/m. As level increased, performance significantly decreased. Irrigating height, stem diameter, fruit yield per compared water, 0 conclusion, performance, conditions.
