Abstract

Magnetic Field Affects Growth and Yield of Sunflower Under Different Moisture Stress Conditions Ananta Vashisth, Neetu Meena, Prameela Krishnan. Magnetic Field Affects Growth and Yield of Sunflower Under Different Moisture Stress Conditions. Bioelectromagnetics. 26 June 2021/ doi: 10.1002/bem.22354 Abstract Magnetic field treatments of seeds have shown significant effects on the enhancement of crop growth. Soil moisture stress is the major constraint in the production of the sunflower crop. Therefore, the experiment was conducted to investigate the effect of a 200 mT magnetic field for 2 h on crop growth, and yield of sunflower crops raised from magnetically treated seeds sown under different moisture stress conditions. Results showed that plants from magnetically treated seeds had higher leaf area index, shoot length, number of leaves, chlorophyll content, biomass, 1000-seed mass, and seed yield as compared with untreated. Radiation use efficiency and water productivity were significantly higher in plants raised from magnetically treated seeds than untreated seeds. Crop raised from magnetically treated seeds had 6.2% more seed yield, 7.1% more protein, and oil content as compared with crops raised from untreated seeds. Hence, it may be concluded that exposure of dry sunflower seeds to the static magnetic field of 200 mT for 2 h could be used for improving crop growth and yield under different moisture stress conditions. onlinelibrary.wiley.com

Main findings

In an experiment exposing dry sunflower seeds to a 200 mT magnetic field for 2 h and sowing under different moisture stress conditions, plants from magnetically treated seeds showed higher growth metrics (e.g., leaf area index, shoot length, chlorophyll content, biomass) and higher yield-related outcomes (1000-seed mass, seed yield) than untreated. Radiation use efficiency and water productivity were reported as significantly higher, and seed yield, protein, and oil content were higher (e.g., 6.2% more seed yield, 7.1% more protein and oil content) in crops raised from treated seeds.
