| Abstract | Among representatives of the world flora in forage production recently the species of the amaranth family, whose vegetative mass is rich in protein, are increasingly being used. The aim of the research was to give a comparative estimation of the productivity of the love-lies-bleeding (Amaranthus Paniculatus L.), to establish the influence of seeding methods and seeding rates on its productivity, to determine the possibility of growing a culture in single-species and combined agrophytocenoses with once cut and double cut use. It has been established that the love-lies-bleeding is the highly productive culture, in the flowering phase 100 kg of dry matter of the vegetative mass contains 50 kg of feed units and 7,9 kg of digestible protein. It forms the highest yielding capacity of green mass (respectively 30,68 and 28,02 t/ha) with continuous row sowing (15 cm) and wide-row sowing (45 cm) and with seeding rate of 1,25 kg/ha. For one-cut use, plants are mowed at a height of 5 cm in the mass flowering phase; for the double-cut use, the first cut is at the beginning of flowering at the height of 15 cm from the soil surface. With once cut use, the highest yielding capacity of green mass (42,38 t/ha) and the collection of dry matter (7,95 t/ha) love-lies-bleeding forms in combined agrophytocenoses with maize, and by double cut use - with sorghum (48,73 and 9,16 t/ha) and Sorghum-Sudan grass hybrid (51,10 and 10,12 t/ha, respectively). | ||
