Abstract
The effects of stationary magnetic field on seeds are studied using two soybean varieties and three
magnetic induction values: 100, 150 and 200 mT during 30 seconds of exposure. The germination
percent, root and stem length as well as fresh and dry mass were measured under laboratory
conditions, at the second week after sowing. The plant grown from treated samples (100 and 150 mT)
and non-treated (B=0) were also evaluated under field conditions. The values of plant height (65 days
after sowing) and the values of pod number, pod length and yield at 110 days (at the end of the plant
cycle), were obtained. The results showed the enhanced of the germination percentage and root length
of the Conquista and Incasoy-24 varieties treated with stationary magnetic field of 150 mT and 100
mT respectively. The rest of the parameters evaluated did not show differences with respect to the
non-treated sample. These respective exposure regimes also provoked a significant stimulation on the
yield and an inhibition on the plant height at 110 days, while the magnetic treatment of 100 mT
enhanced significantly the plant height of Incasoy-24 variety at 65 days after sowing (P<0.05).
