grass mixture on nutritive value of forage. Agronomy 2010/2011, 133138. Complementary species are used in legume-grass mixtures in order to use environmental resources efficiently and reduce N emission. The aim of this investigation was to study the common lucerne (Medicago sativa, L) ´FSG 408 DP´ and hybrid lucerne (Medicago varia, HL) ´Karlu´-grass mixtures during the years 2007-09. The grasses used in the mixture were hybrid- ryegrass ´Molisto´, tall fescue ´Seine´, meadow fescue ´Darimo´, reed canarygrass ´Palaton´ and smooth bromegrass ´Lincoln´. Maturity stages were accompanied by significant changes in nutritive value: increased NDF, decreased CP, DDM, ME. Especially in the first cut the quality declines rapidly when the forage biomass increases. Dynamics of quality changes depended on the speed of species' seasonal development. Botanical composition of lucerne-grass mixtures showed positive
burned at the processing facility due to the cost of transportation. Sunflower can be used as a forage, although this is not common. When it is grown as a silage, the most appropriate harvest stage is when about half of the head area has immature seeds. The plants should be allowed to wilt and lose moisture before being ensiled. The crude protein level of sunflower silage is greater than that of corn silage. It is about the same as that of tall fescue hay but lower than that of alfalfa hay. If sunflower is not cut for silage until after the flowering stage, crude protein level will decline and lignin content will increase. Sunflower silage is considered adequate for steers and dry cows or low milk producers, but not for high-producing milk cows. Industrial Like most oilseeds, sunflower has potential for many industrial products, but has not been used much for non-food, non-feed purposes in the U.S. Because sunflower oil is used for
