ASSESSMENT RESULTS OF SAINFOIL CULTIVARS IN THE ROSTOV REGION

The production needs sainfoil varieties adapted to different and changing weather-climatic conditions of the region with high productivity of green mass, dry matter, seeds and good quality of fodder. The demands of the production can be significantly satisfied with new sainfoil cultivars of I.G. Kalinenko ARRIGC. The sainfoil varieties studied in three cycles of sowing are characterized with early germination in the spring (on 24-25 of March). The period lasts 58-59 days from the beginning of the germination till harvesting maturity of green mass and it lasts 90-91 days till full maturity of seeds. The amount of leaves of the cultivars ‘Atamansky’, ‘Sudar’ and ‘Veles’ is of 44%, 43% and 42% respectively. The studied varieties formed a higher productivity of green mass and seeds than the standard variety during the years and cycles of growing. The variety ‘Atamansky’ produced 28,3 t/ha of green mass, ‘Sudar’ - 27,8 t/ha, ‘Veles’ - 27,4 t/ha, that is on 3,0 t/ha, 2,5 t/ha and 2,1 t/ha more than of the standard variety. As for the seed productivity they produced 0,71 t/ha, 0,68 t/ha and 0,69 t/ha respectively, that is on 0,08 t/ha, 0,05 t/ha and 0,06 t/ha more than of the standard variety. The studied varieties formed a higher productivity of dry matter than the standard variety. The varieties ‘Atamansky’ and ‘Sudar’ produced 7,9 t/ha, ‘Veles’ – 7,8 t/ha. The varieties ‘Atamansky’ and ‘Sudar’ are characterized with the largest harvest of fodder units per hectare (4,11 th/ha). The variety ‘Veles’ produced 4,06 th/ha, and the standard variety produced 3,69 th/ha. The variety ‘Sudar’ gave the largest amount of raw protein (1,05 t/ha). The varieties ‘Veles’ and ‘Atamansky’ produced only 1,03 t/ha and 0,99 t/ha of raw protein. As for the amount of digestible protein per fodder unit the varieties ‘Sudar’ and ‘Veles’ showed the largest indexes (255 g/f.u. and 253 g/f.u. respectively).
