The effect of a weak permanent magnetic field (PMF) with a strength of 62 T on chilli (Capsicum annum. L.) seed germination, growth and development was investigated. Four pre-sowing treatments at different times (4, 8, 12, and 24 h exposure) of chilli seeds were carried out in the experiment to compare with the untreated control. PMF had a stimulating effect on the first stages of growth of chilli seeds for all exposure times studied. Statistically processed experimental data suggest that the effect of PMF significantly increased seed germination and initial development and growth compared with the untreated control. It was also identified that variation in seed germination, emergence and development existed between the north and south poles, and the seeds treated with south pole were showing maximum growth status as compared to north pole and untreated control.
