The results of our experiments in which the cotton seeds were subjected to the action of ultra-short electromagnetic waves of 3 metres for 10, 20, 30, and 40 minutes, the seeds being placed between two Cu plates in the parallel Hartray circuit, showed that waves exerted, in each case tested, a fabourable influence on the growth of plants and on the opening of flowers and that of bolls. especially these waves emitted for 20 minutes exercise the most favourable action on the development of cotton plants.
