摘要

Magneto-priming, a novel non-chemical seed pre-treatment technique, has shown potential to enhance the resilience, productivity, and overall health of rice crops, particularly under abiotic stress conditions. By briefly exposing seeds to a controlled magnetic field prior to sowing, magneto-priming can modulate physiological and biochemical processes that improve germination, seedling vigour, and early nutrient uptake. Previous studies have reported that seed magneto-priming can lead to germination improvements of approximately 15–20% and yield gains ranging from 3–8%, although the extent of response varies with rice genotype, magnetic field intensity, and exposure duration. Evidence from existing literature also suggests that magneto-priming may support improved micronutrient absorption and grain quality, offering scope for nutritional enhancement; however, claims such as vitamin B12 enrichment remain prospective and require validation through grain-level analyses. Furthermore, the review discusses the potential of magneto-priming to reduce dependence on chemical inputs and promote sustainable rice production systems. Overall, magneto-priming represents a promising yet underutilized strategy for enhancing rice performance and supporting smallholder farmers amid the challenges of climate change and resource limitation.
