Following many years of research, it has been determined that for the environmentally friendly stimulation of the growth of plants and increase of their yields, it is necessary to apply pre-sowing electromagnetic treatment to the seeds of these plants.A study has been carried out of the impact of the pre-sowing electromagnetic treatment of the seeds of different Bulgarian wheat varieties and of maize hybrids provided by Bulgarian producers and by the companies Pioneer-USA and the French Maisadour Semences.At certain values of the controllable factors of the pre-sowing treatment, the following results have been achieved: an increase of (9...20)% in wheat yields as compared to the control batch, and an increase in the length of the maize ears, a higher number of leaves and a higher number of kernel rows in an ear, a higher number of kernels in a row, and yields increased by (5...21)% as compared to the control batch.Following many years of research, it has been determined that for the environmentally friendly stimulation of the growth of plants and increase of their yields, it is necessary to apply pre-sowing electromagnetic treatment to the seeds of these plants.A study has been carried out of the impact of the pre-sowing electromagnetic treatment of the seeds of different Bulgarian wheat varieties and of maize hybrids provided by Bulgarian producers and by the companies Pioneer-USA and the French Maisadour Semences.At certain values of the controllable factors of the pre-sowing treatment, the following results have been achieved: an increase of (9...20)% in wheat yields as compared to the control batch, and an increase in the length of the maize ears, a higher number of leaves and a higher number of kernel rows in an ear, a higher number of kernels in a row, and yields increased by (5...21)% as compared to the control batch
