The ability of grazing animals to enhance quality of diet by selection is important in production. The study determined the effects of selection on dietary quality of cattle grazing monocultures of smooth bromegrass (Bromus inermis Leyss; SB), switchgrass (Panicum virgatum L.; SG), and big bluestem (Andropogon gerardii Vitman; BB) as influenced by plant maturity. Three ruminally-fistulated stee...

VASILEVA, V., E. VASILEV and R. TZONEV, 2016. Subterranean clover (Trifolium subterraneum L.) as a promising forage species in Bulgaria. Bulg. J. Agric. Sci., 22: 222–227 The paper presents an overview of the possibility to use the subterranean clover (Trifolium subterraneum L.) (an annual leguminous self-seeding species, widespread component in the pastures of the temperate areas of Central an...

Concentrated sources of dairy manure represent significant water pollution potential. The southern United States may be more vulnerable to water quality problems than some other regions because of climate, typical farm size, and cropping practices. Dairy manure can be an effective source of plant nutrients and large quantities of nutrients can be recycled through forage production, especially w...

Pasture renovation entails introduction of desirable forage species, usually legumes such as red clover (Trifolium pratense L.), white clover (Trifolium repens L.) or birdsfoot trefoil (Lotus corniculatus L.), into a grass dominated pasture. A commonly used method of pasture renovation consists in drilling seeds into the grass sod (sod-seeding). Introduced legumes benefit the pasture in three w...

Clovers and other legumes are highly desirable species in pastures and hay meadows. First, legumes are able to obtain nitrogen from air through their symbiotic relationship with Rhizobium bacteria and, there­ fore, are not dependent on nitrogen fertilizer. The fixed nitrogen is primarily used to support clover growth, but parts of it become avail­ able to neighboring grass plants when clover ti...

Short-duration grazing (SDG) has been purported to increase forage production and utilization compared to other grazing systems, and thus can sustain higher stocking rates. This study was designed to determine if standing crop could be mahttained as stocking rates increased. Four stocking rate treatments ranging from the recommended rate for moderate continuous grazing to 2.5 times the recommen...

Montana is a typically low-rainfall area with limited irrigation in some areas. Moisture is critical for producing high-yielding, highquality forages. Finding forage species that can produce both a high-quality and high-yielding product is important for livestock producers throughout Montana and the region. While quality of perennial and annual grasses may be comparable to corn, their yield per...

The tribe Triticeae is a taxon in the Poaceae that includes several important cereal crops and forage grasses. All its species, including those that are not used for cereals or forage, are potential sources of genes for crop and forage improvement so they all have high economic value. Taxonomic treatments, including those of the Triticeae, are the basis for identification. They are often design...

M crested wheatgrass stands in western North Dakota were established 15 to 20 years ago. These fields are still used for hay and pasture, and many are still in excellent condition. One field at the Dickinson Experiment Station, seeded in 1938, has produced an average of 1,262 pounds of forage per acre (dry weight) over the past 12 years. However, there is good evidence that the productivity of ...

DEDICATED ENERGY CROPS AND MODELS Lignocellulosic biomass derived from energy crops and agricultural residues is a promising renewable source for the production of transportation fuels and bio-based materials. Plants exhibiting C4 photosynthesis are amongst the most promising dedicated energy crops as they possess tremendous intrinsic efficiency in converting solar energy to biomass. Van der We...
