The objective of this study was to evaluate the best level of inclusion of cactus pear in the ensiling of elephant grass Brazil seeds (BRS) capiaçu (Pennisetum purpureum), its effects on fermentative characteristics; and nutritional value. Experimental treatments consisted of BRS capiaçu grass silage with five levels of inclusion of cactus pear (0, 5, 10, 15 and 20% inclusion as fresh ...

Tifdwarf bermudagrass (Cynodon sp. (L.) Pers.) sod-plugs were treated with two rates of five herbicides (DCPA, Benefin, Bensulide, Terbutol and Kerb) to determine effects of these chemicals on shoot and root growth. Ap plication rates were those commonly used for weed control and twice this recommended rate. Herbicides were applied on top of the sod and below the sod to simulate surface treatme...

response of seed germination of a crop to different environmental conditions is one of the most important determination factors to indicate its ability in competition with weeds. in order to evaluate the effects of water depth and temperature on the germination of different varieties of rice and barnyard grass, an experiment was conducted in the seed laboratory, faculty of agriculture, ferdowsi...

Asystasia gangetica is considered one of the invasive weeds and often found in residential areas most important to plant. The aim study was evaluate effectiveness interaction between extract concentration leaf condition Terminalia catappa L. extracted from gangetica. conducted using a completely randomized design two factors. first factor leaves, which were fresh, newly fallen dried leaves. sec...

Longleaf pine (Pinus palustris Mill.) is an important softwood species in the southeast United States. In presettlement times, this species occupied extensive, pure stands throughout the Atlantic and Gulf Coastal Plains from southeastern Virginia to eastern Texas, as well as south throughout the northern two-thirds of Florida. Its range also includes the Piedmont Ridge and Valley, and Mountain ...

Background: Dedicated bioenergy crops such as switchgrass (Panicum virgatum L.), miscanthus [Miscanthus x giganteus (Mxg)], indiangrass [Sorghastrum nutans (L.) Nash], and big bluestem (Andropogon gerardii Vitman) can provide cellulosic feedstock for biofuel production while maintaining or improving soil and environmental quality. To better understand bioenergy crop effects on soils, we studied...

The research was conducted to determine the effect of different temperatures on germination and early seedling growth grass pea (Lathyrus sativus L.). Two cultivars (Gürbüz-2001, Karadağ) a population (Pop-Diyarbakır) were used as experimental materials. study in complete randomized split-plot design with four replications chamber. rate, mean time, shoot length, root dry weight, fresh weight de...

We present a novel approach for solving different design problems related to single products in multipurpose batch plants: the selection of one production line out of several available, additional investment into an existing line or plant, and grass-root design of a new plant. Multiple objectives are considered in these design problems. Pareto-optimal solutions are generated by means of a Tabu ...
