The 20th century is to be noticed, among other things, for the technical and technological revolution in all the fields of activity. Bernard C. said that biology “should take over from physics and chemistry the experimental method while preserving its own phenomena and laws”. At present, at international level, it is known that electromagnetic waves act on the water structure in cells, with beneficial effects on both germination and plants in vegetation. In this paper we present the positive effect of 5 frequencies whose wave lenghts is between 0-100 Hz on maize plants growth comparative to the control. Measurements concerned the fresh weight of the root (mg), the dried weight of the root (mg), the volume of the root (ml), the fresh weight of the aerial part (mg), the dried weight of the aerial part (mg), the length of the aerial part (mg), and the length of the root (cm). these measurements were made 30 days after plant sprouting. Research was carried out in the laboratory of „Agricultural produce quality analysis” of the Department of Agricultural technologies of the Faculty of Agriculture of the Banat University of Agricultural Science and Veterinary Medicine in Timişoara, using 1/1 boxes; the nutritious solution was used after the Jork method that best renders soil conditions. In the experiment, we used as genetic material the maize hybrid PR37D25 developed by the Pioneer Hi Bred Seed Co., and in the treatment of the seeds we used the generator of electromagnetic radiations of the Faculty of Agriculture of Novi Sad thanks to Professor Branko Marinkovic, a member of the research contract that finances the present study. The results of the present study are part of a research project PN II IDEI Contract nr. 1076/2009, topic code ID_864, financed by the Ministry of Education, Research, Youth and Sport, through the National Council of Scientific Research in Higher Education. The topic of the project is „Study concerning low-frequency electromagnetic waves effect on crop and quality in maize”.
