BIOLOGICAL POTENTIAL OF LEGUMINOUS PLANTS AND PROBLEMS OF THEIR EFFICIENT USE IN CONDITIONS OF THE CENTRAL CAUCASUS
This research deals with concept development, theoretical and practical justification of biological potential of leguminous plants grown in conditions of the Central Caucasus, with the use of modern innovative resource-saving technologies. This is due to the fact that in modern complicated economic and environmental situation, consumers have become more educated and demanding in product choosing, focusing on priority of environmentally safe, rich in essential components products that make up protein, carbohydrates, vitamins and minerals deficiency in body. Therefore, the existing conditions make researchers to look for new and innovative ways of public health improving due to production of products containing active and ecologically safe components, with preservation of raw materials useful properties. The use of different instruments for regulation of elements content in ecosystems allows to stabilize their optimal level, improving general background of the surrounding world, and diagnostics of mineral nutrition of plants promotes forecasting, quality control, and modeling of formation of crop yields grown in the ever-changing environment. Leguminous plants potential grown on four subtypes of soils of foothill landscapes has been studied. Microelements for root nutrition and plants foliar feeding, as well as for pre-sowing treatment of seeds, in the form of low concentrated solutions of salts have been used, they are: 0,03-0,05% solution of ammonium molibdate (NH4)2 MoO4; 0,02-0,03% solution of copper sulfate - CuSO4*5H2O; 0,01-0,02% solution of manganese sulfate - MnSO4; 0,05-0,08% solution of zinc sulfate - ZnSO4; 0,01 - 0,03% solution of nitrate cobalt - Co(NО3)2, 0,01-0,02% solution of Fe-DTPA (iron complex with diethylenetriamine - acetic acid).
