Effect of Magnetic Field on Germination of Purple Eggplant (Solanum melongena L) using Helmholtz Coils

Abstract

Research has been carried out on the effect of magnetic field on the germination of purple eggplant (Solanus Melongena L) using Helmholtz coil. This research aims to determine the effect of exposure to a magnetic field and exposure time on the germination of purple eggplant. This study used 100 samples of purple eggplant seeds, of which 10 samples were controls (0 mT) and 90 samples were exposed to a magnetic field 0,3 mT, 0,4 mT and 0,5 mT which was divided into three exposure treatments, namely 15 minutes/day, 25 minutes/day and 35 minutes/day for 7 days. Based on the data obtained, it is proven that the strength of the magnetic field and the long exposure time have an effect on the growth and increase in the length of purple eggplant seed sprouts.  The optimum magnetic field strength and exposure time is 0.4 mT and exposure time is 25 minutes/day.
