Grain moisture at harvest time and weight features of seeds are more or less impacted, depending on agro-technical, climate, etc. factors. Likewise, in agricultural practice, high values of these indicators show that, as far as germination is concerned, seeds have well-developed germs resulting into vigorous plants and into higher wheat yields from a technological point of view. In this study, the authors monitored the effect of different low-frequency wave lengths on moisture, relative volume of 1,000 grains, and hectolitric volume in the maize hybrid PR36V74, developed by Pioneer, and grouped in the maturity class FAO 450. The working method used in the experiment is specific to laboratory determinations, while 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. We should mention that we used in the treatment of the seeds only frequencies known to stimulate plant growth and measuring between 0 and 100 Hz. Research was carried out in the laboratory of „Agricultural produce quality analysis” of the Department of Agricultural technologies of the Faculty of Agriculture. Results show that electromagnetic radiations produce, depending on their wave length, a positive stimulation on the three monitored indicators compared to the control variant (not stimulated electromagnetically). 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 „ A study on the influence of the treatment with low-frequency electro-magnetic waves on yield, and quality in the maize”.
