Title : Fodder productivity of different meadow clover varieties depending on the elements of growing technology

Abstract :

The article presents the results of research for 2018-2020 concerning formation of fodder productivity by the dry mass outcome of meadow clover different varieties per 1 ha depending on the methods of sowing on different backgrounds of fertilizers on typical low-humus black soils of Forest-steppe of Ukraine. On average, in the first three years of life and usage, meadow clover provides productivity of dry mass outcome per 1 ha - 8.22-9.88 tons, which depends little on sowing methods. When inoculating seeds with nodule bacteria in combination with application of fertilizer in the doze of N60P60K90 the productivity increases by 8-12% comparing to the variant without fertilizers. And, with separate application of fertilizers (Р60K90 or N60P60K90) or inoculation of seeds on the background without fertilizers the productivity increases only by 4-6%. Among fertilizers, the highest payback from 1 kg of fertilizer (6-7 kg of dry mass) is provided by application of N60 on the background of Р60K90. In the first year, sowing under the cover of spring barley provides 22-25% higher productivity than uncovered sowing, and in the second and the third years, uncovered sowing provides 7-10% higher productivity than sowing under the cover of spring barley. The most productive variety is Typhoon, which is 0.10-0.66 t/ha of dry mass superior to the varieties Lybid and Tina. Fertilizer factor is the most influential by dry mass outcome per 1 ha, and in the first year - the method of sowing with a share of 55%.
