Use of a gradient magnetic field in the pre-sowing treatment of cucumber seeds

The purpose of these studies was to develop optimal modes of magnetization of cucumber seeds when cultivated in protected soil. The research task included the study of the effect of the gradient magnetic field (GrMP) on seed sowing qualities, growth processes and photosynthetic ac-tivity of cucumber plants, and crop productivity. The experiments were carried out in 2 stages, in-cluding laboratory and greenhouse soil tests. The study used generally accepted methods of estimat-ing seed quality, observing plant growth and development, taking into account the main indicators of phenophases, forming generative organs, determining crop and product quality. By experimental method positive effect of treatment of cucumber seeds with gradient magnetic field is confirmed. Stable stability of magneto-biological effects in cucumber seedlings was observed at a seed speed of 1-2 m/s in a magnetic field and its intensity in the range of 50-150 E. Plants formed from treated seeds were characterized by higher photosynthesis productivity, a large number of female flowers compared to control. Productivity growth in experimental versions by 7.6-15.3% was due to a larger number and mass of formed fruits. Magneto-biological effects in cucumber plants were observed throughout ontogenesis and culminated in an increase in its productivity.
