The prospects of cultivation of Hedysarum alp'inum L. in Non-Chernozemzone of the Russian Federation

The study presented four-year experimental data dealing with apply of growth regulators and microfertilizers in the cultivation of Hedysarum Alpínum L. It was established that soaking of seeds with growth regulator Epin-extra promotes the increase in the density of plants’ standing, subsequent processing on the first year of vegetation of Epin-extra (40 ml/hectare) and its complex with microfertilizer of Citovit (0.5 l/hectare) leads to strengthening of growth processes, height of plants exceeds control by the end of vegetation for 51 % whereas when processing Epin-extra - by 29 %, the crude mass of plants increased by 53 and 24 % respectively by processing options. System extra root top dressing by microfertilizers of Ferovit and Citovit led to strengthening of growth of plants of Hedysarum Alpínum L of the second year of vegetation, their height at the time of harvesting surpassed the control for 28 and 35 %, productivity of raw materials increased in comparison with control by 36 and 39 % and promoted the increase of the content of active ingredient of mangiferin for 10 and 12 %. The use of growth regulators Zircon and Epin-extra helps to increase the yield of Hedysarum Alpínum L. seeds. The researches showed that the effect of Zircon was manifested largely and contributed to the increase compared to the control in seed yield by 31 %, the mass of 1000 seeds by 12 %, and seed germination - by 1 7. In the variant with Epin-extra these indicators exceeded the control by 24 %, 9 and 16 % respectively.
