Abstract
Pre-sowing treatment of agricultural crops seed in a magnetic field promotes increase of productivity of agricultural crops, decrease of plant morbidity and increase of quality of products. To implement it, it is necessary to establish all operating factors and determine their optimal values. The purpose of the study was to determine the effect of the magnetic field on the crop quality of rye seeds and their changes in time after treatment. On the basis of the conducted researches it was established that the active factors in the treatment of seeds in a magnetic field are the magnetic induction, the number of magnetization, the pole division and the velocity of the seed in a magnetic field. Experimental studies were performed by experiment planning. The factors was the magnetic induction and the velocity of the seed, and the initial values - the energy of germination and the similarity of rye seeds. When the magnetic induction is changed from 0 to 0,065 T, the energy of germination and the germination of the rye seeds increase, and with further increase of the magnetic induction begin to decrease. The sowing seed quality changes by the velocity of their movement in the magnetic field and the pole division, although they are less significant factors than the magnetic induction. It has been established that the most effective pre-treatment treatment of rye seeds in a magnetic field is the magnetic induction of 0.065 T with a fourfold reversal magnetization, a velocity of 0.4 m/s and a pole division of 0.23 m. In this mode of pre- sowing treatment of seed in a magnetic field, the germination energy is relatively with control increased by 30 %, and germination – by 26 %. The effect of magnetic treatment of rye seeds is stored within a month after treatment. At the same time, the germination energy and germination decrease by no more than 4 %.
