In the context of the reduction of the acute deficit of protein, it is necessary to extend the areas with crops rich in protein, such as those of the family Fabaceae Lindl. The Astragalus ponticus Pall. plants, from the collection of nontraditional fodder plants of the Botanical Garden (Institute) of ASM, maintained in pure culture, served as object of study. As a result of the conducted researches, it was established that in order to germinate abundantly the seeds of A. ponticus needed to be scarified and that in the first year of vegetation they had a slow growth and development. In the following years, A.ponticus plants started to grow 5 days later than Medicago sativa L., the flowering period started simultaneously and the seeds’ ripening 26 days earlier. The seed production of A. ponticus in the conditions of Moldova constituted 40.90 g/m2 (27.14 g/m2 of the .sativa). The maximum accumulation of green mass at A. ponticus occurred during the budding stage and the harvest constituted 1.48kg/m2, with a high content of dry matter. 1 kg of natural fodder contained 63.84 g raw protein, 47.27 g digestible protein and 7.90 g fats, compared with 46.10 g, 34.50 g and 20.0 g of the alfalfa. The natural fodder of A. ponticus had a
high content of essential amino acids such as threonine, valine, isoleucine, lysine and a low content of methionine, phenylalanine and arginine. It was also rich in carotene, vitamin C, in minerals, especially phosphorus (1.23 g/kg natural fodder compared with 0.54 g/kg in the control variant M. sativa) and had a high content of digestible protein 225.09 g/nutritive unit (164.29 g of the M. sativa). |
