Abstract
Introduction. The strategic objective of efficient land management in cultivating industrial crops is the increase of their yield while maintaining the quality of the raw materials obtained that can be achieved if prepare high-quality seed material.
Aim of the Study. The study is aimed at determining experimentally the effect of presowing treatment of fibre flax seeds in a direct current magnetic gradient field on their growth, development and productivity.
Materials and Methods. The study object was fibre flax seeds. To vary the parameters of the gradient magnetic pre-sowing treatment modes, there was used a specialized laboratory setup, which allows adjusting the gradient magnetic field parameters within the following ranges: magnetic field induction inside the working chamber – from 0.83 to 8.00 mT, current in the windings – from 0.2 to 2.0 A, and supply voltage – from 2.5 to 25 V. Seed treatment and studies germination ability and germination energy were carried out under laboratory conditions. The field experiments were conducted on an experimental plot, the soil of which was soddy-medium-podzolic light loamy residual carbonate gleyic on moraine with content – 1.6%; labile phosphorus P2O5 – 345 mg/kg, exchangeable potassium K2O – 85 mg/kg; pHKCl – 5.03; thickness of the arable layer – 20–22 cm.
Results. The germination energy of the treated seeds increased on average by 11.4%, and laboratory germination – by 14.8%. The results of field studies confirmed the positive response of seeds to the treatment – the overall survival of fibre flax plants in certain variants increased from 22.9% (control) to 35.6%. There has been recorded that the fibre flax straw yield increased from 25.6 (control) to 51.8 c/ha, and flax seed yield – from 6.6 (control) to 12.6 c/ha. Since fibre flax was cultivated for seeds, there has been determined the multiplication coefficient. In certain variants, it was 32, 33 and 37 units, compared to 17 units in the control.
Conclusion. The best response of flax seeds (germination, growth energy, etc.) was recorded after treating in a magnetic field with an induction of 5.81, 6.70 and 7.35 mT. These magnetopriming parameters make possible a technically simple and cost-effective treatment of seeds and their five-day warehouse storage followed by sowing into the soil. Further research may be aimed at conducting long-term observations that will allow preparing recommendations for using this agricultural method at agricultural organizations and farms involved in seed production and intensive cultivation of fiber flax.
