THE PERSPECTIVE OF CULTIVATION AND UTILIZATION OF THE NEW LEGUMINOUS GRASSES SPECIES IN MOLDOVA

The development and modernization of our country’s agriculture is related to the revitalization of the animal breeding sector along with the implementation of new genotypes of animals and diversification of fodder production, balanced in terms of quantity and quality throughout the year, suitable for the physiological requirements of animals, and qualitative products as required in the market. Scientific research conducted in the Botanical Garden (Institute) of the ASM over decades was aimed at mobilization, improvement and implementation of new non-traditional plant species that use efficiently photosynthetic active radiation and land resources to obtain fodder with a high level of vegetable protein, the fodder leguminous grasses (fam. Fabaceae Lindl.) play an important role. We have studied the biological peculiarities, productivity, chemical composition and nutritional value of new fodder leguminous plant species Astragalus galegiformis, Onobrychis inermis and Medicago tianschanica of the collection of non-traditional fodder plants of the Botanical Garden (Institute) of the ASM, the traditional forage crop alfalfa served as control variant. The nutritional value of fresh mass accounts: the Astragalus galegiformis - 0.27 nutritive units, 3.26 MJ metabolizable energy and 146g digestible protein/nutritive unit; Onobrychis inermis - 0.25 nutritive units, 2.56 MJ metabolizable energy and 154 g digestible protein/nutritive unit; Medicago tianschanica - 0.24 nutritive units, 2.86 MJ metabolizable energy and 173 g digestible protein/nutritive unit and alfalfa - 0.21 nutritive units, 2.28 MJ metabolizable energy and 164 g digestible protein/nutritive unit. Due to the productivity and high and stable quality of fodder, use of the plantation for a long period of time, capacity of fixing atmospheric nitrogen, the new fodder leguminous species Astragalus galegiformis, Onobrychis inermis and Medicago tianschanica can serve as initial material for enriching the range of forage crops.
