forage species in mixtures are extensively grown worldwide nowadays, particularly as a step towards sustainable agriculture, however, information on this topic is scanty in our country. thus a 2-year (2001-2003) field experiment was conducted to determine the forage yield, botanical composition, as well as competition of some forage grasses and legumes as mono and dual cultures combinations at ...

Two in situ protein disappearance experiments were conducted to determine disappearance rates of leaf protein fractions and characterize individual leaf protein fractions that escaped ruminal degradation. Fresh leaf blades of two warm-season grasses, switchgrass (Panicum virgatum L.) and big bluestem (Andropogon gerardii Vitman), and one cool-season grass, smooth bromegrass (Bromus inermis Leys...

Development of new tillers in smooth bromegrass is largely determinant, with synchronized elevation and Smooth bromegrass (Bromus inermis Leyss.) is poorly adapted to elongation of new apical meristems above the soil surmanagement-intensive rotational grazing because of slow and limited regrowth potential. In an effort to find existing germplasm with tolerface (Krause and Moser, 1977). Cutting ...

A significant part of arable lands on slopes is subject to removal from active processing, and alkalization with perennial herbs. We know that the most productive are those agro-phytocenoses, forming based a single-species sowing alfalfa (Lucerne), its mixture cereal grasses. However, restrictive factor alfalfa-cereal grasslands high productivity soil solution acid reaction. The research carrie...

In a 3-yr study, 135 crossbred steers (330 ± 10 kg) were used in a randomized complete block design to evaluate corn dried distillers grains plus solubles (DDGS) fed to yearling steers as a substitute for forage and N fertilizer and its effect on N use efficiency in yearling steers grazing smooth bromegrass pastures. Steers were initially stocked at 6.8 animal unit months (AUM)/ha on nonfertili...

Alfalfa (Medicago sativa L.) persistence and forage and cow-calf production were evaluated on pastures containing smooth bromegrass with or without grazing-tolerant or hay-type alfalfa cultivars rotationally stocked in either a season-long or complementary system. In 1997, six 2.02-ha pastures were seeded with smooth bromegrass, a mixture of a grazing-tolerant alfalfa (Amerigraze variety) and s...
