The invention relates to a method for the treatment of plants using electromagnetic fields and consists in applying pulse sequences to growing plants or the seeds thereof in a pulsed electromagnetic field by means of a pulse generator, wherein the individual pulses have a frequency ranging from 1 to 100 Hz and the amplitude of each individual pulse corresponds to an exponential function or the pulses have envelope curves rising and falling in the form of an arc, wherein the individual pulses are emitted in synchronous or asynchronous groups of pulses having different magnetic flux densities, and wherein the plants are exposed to the pulsating electromagnetic field once to 30 times a day for 1 to 120 minutes each time or continuously for several days. Plant growth, germination and yields are significantly increased in an environmentally friendly manner. Resistance to diseases is increased.
