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

The reclamation of new areas and distant lands with limited energy and material resources demands using resource- and energy-saving technologies. One of such technologies can be magnetic treatment of irrigating water and artificial manure solutions, and presowing treatment of seeds of agricultural crops in magnetic field. The authors found that magnetic field accelerates the velocity of chemical reactions, enhances salts and fertilizers solvability, and increases oxygen concentration in a solution. Magnetic field improves membrane cells permeability which accelerates molecules and ions diffusion through it. This process improves the ability of a seed to absorb water and increases the concentration of oxygen in a cell. Presowing treatment of seeds increases their ability of germination by 26–50%, sprouting by 20–30%. The best regime of water solutions and seeds of agricultural crops treatment in magnetic field is when magnetic induction is 0.065 Tl and the velocity of a solution is 0.4 m/s.

Effect of magnetic field on seed germination and seedling growth of sunflowerThe impact of a variable magnetic field, magnetically treated water and a combination of both these factors on the germination of seeds and the final mass at the initial stage of growth sunflower plants was presented. Investigations were carried out in pots filled with sand, tin an air-conditioned plant house with no access to daylight using fluorescent light as illumination. A statistical significance positive impact was achieved for the samples subjected to the interaction of both stimulating factors simultaneously, the magnetic field and the impact of treated water several times on the speed of seed germination and final plant mass. Negative impacts were obtained for the majority of the test cases, for the magnetically treated water, the short duration of activity of the magnetic field and for the connection of the magnetic field and low-flow times.

Context: Producing high quality and chemical free tomato would favorably enhance consumer preference. There are most promising findings available on growth and quality attributes of tomato and other plants under different light spectrum in closed house conditions using different light sources. Installment of light emitting devices and running cost with high power consumption might not favorable for commercial cultivators and small scale growers. Aim: In present study we used colour transparent sheets such as colourless (control), red, blue, green and yellow as shading material to transmit respective spectrum of light on tomato plants to study the effect. Methodology: Tomato seed germination study was done under different colour shading in petri plates. Seedling and plant growth parameters and phytochemical properties of tomato plants grown under different transparent colour shadings were studied such as number of leaves, leaf area, weight of shoot and root, chlorophyll content, ascorbic acid content of fruits, lycopene contents of fruits, fruit physical parameters and flowering. Results: Seed germination was significantly high under yellow, colourless and red shading over blue and green. Seedling growth was significantly high under yellow shading. Fruit Ascorbic acid content was positively enhanced by yellow, green and colourless shading, whereas chlorophyll and lycopene content significantly high under green and red. Number of flower setting per plant was high under green shading (40±5.77), whereas lowest under yellow shading (22.33±6.38). Fruit setting significantly high under yellow shading (14±2) and lowest was red (9±1). Blue shading showed significantly high effect on fruit morphological traits such as pericarp thickness and fruit size. Conclusion: Yellow colour shading enhances seedling growth and fruit setting of tomato, while green having positive impact on fruit morphology. However, different characters of tomato were differently affected by different colour shading in greenhouse condition and for the better effect appropriate colour shading should be selected at particular stage of growth.

The Alleviation Effect of Silicon on Seed Germination and Seedling Growth of Tomato Under Salinity StressThis study was conducted to evaluate the effectiveness of silicon (Si) application under salinity levels on seed germination and growth characteristics of tomato seeds. A laboratory experiment was performed on completely randomized design with two levels of salinity (25 and 50 mM NaCl) and 2 concentration of Si (1 and 2 mM) with 4 replications. Germination percentage, germination rate, seedling shoot and root length, fresh and dry weight of seedling and mean germination time was measured. Seed germination ofLycopersicon esculentumL. was significantly affected by salinity levels, Si and their interaction. Germination characteristics of tomato seeds decreased drastically by increasing NaCl concentrations. However, 1 mM Si had positive effects on seed germination characteristics and improved germination percentage, germination rate and mean germination time. Si alleviated the harmful effect of salinity stress on tomato seed germination at almost all germination characteristics.
