Magnetic Field Affects Growth and Yield of Sunflower Under Different Moisture Stress Conditions

Abstract

Overview

Magnetic field treatments of seeds have been studied for their potential to enhance crop growth, particularly under stress conditions such as varying moisture levels.

Experiment Details

An experiment was conducted to investigate the effects of a 200 mT static magnetic field for 2 hours on the growth and yield of sunflower crops. These crops were raised from seeds that were magnetically treated and then planted under different soil moisture conditions.

Findings

• Increased leaf area index, shoot length, and number of leaves in magnetically treated seeds.
• Higher chlorophyll content, biomass, 1000-seed mass, and seed yield compared to untreated seeds.
• Significant improvements in radiation use efficiency and water productivity in crops from treated seeds.
• Enhanced seed yield by 6.2%, with protein and oil content up by 7.1% compared to crops from untreated seeds.

Conclusion

Exposure of dry sunflower seeds to a 200 mT static magnetic field for 2 hours can improve crop growth and yield under various moisture stress conditions. This technique offers a potential advantage for agricultural production in moisture-limited environments.
