Alfalfa is the most important forage plant in our country. It is mainly grown as pure crop for livestock nutrition, although it gives very good results when grown in mixture with other plant species. By growing in mixtures many advantages are achieved, the most important are: possibility for alfalfa to be used in grazing and reduced need for fertilization of grassland. In two year trial (2003-2004), changes in botanical composition of alfalfa mixtures depending on the present species in the mixture, i.e. their competitive abilities and fertilization with N, were monitored. Investigations showed that by ageing of crops the share of grasses increases and share of legumes and weeds decreases. Fertilization showed positive effect on strengthening of competitive abilities of grass in relation to leguminous species and increased share of weeds in forage mixtures.

Forage Mixtures

A comparative study was made in 1958 of the visual estimation and hand separation methods of determining botanical composition of two-component forage mixtures. The results indicated that there were positive significant correlations between the per cent legume values obtained by the two methods. The visual estimation method was less variable than the hand separation method and the precision per unit cost was greater. The differences between per cent legume values obtained by the two methods were influenced by the stage of maturity (medium or late hay) of the components and the cut (hay or aftermath). In this study, the difference was significant only in the medium aftermath cut.Individually, three observers showed some inconsistencies between estimates on the medium and late maturity groups and between the hay and aftermath cut. However, by averaging the three estimates to obtain a mean sample, these inconsistencies were minimized.Both methods were more precise in the aftermath pasture cut than in the hay. An additional observer increased precision of the visual estimate more than an additional replicate or sample. The greater precision resulting from additional replicates, samples, or observers increased at a decreasing rate. The number of replicates, samples, and observers required for specific degrees of precision and a specific cost were calculated.The experiment showed that the visual estimation method can be superior to the hand separation method as a means of determining botanical composition.

AbstractAgricultural intensification within forage systems has reduced grassland floral diversity by promoting ryegrass (Lolium spp.), damaging soil functionality which underpins critical ecosystem services. Diverse forage mixtures may enhance environmental benefits of pastures by decreasing nutrient leaching, increasing soil carbon storage, and with legume inclusion, reduce nitrogen fertilizer input. This UK study reports on how species-rich forage mixtures affect soil carbon, phosphorus, and nitrogen at dry, medium and wet soil moisture sites, compared to ryegrass monoculture. Increasing forage mixture diversity (from 1 to 17 species) affected soil carbon at the dry site. No effect of forage mixture on soil phosphorus was found, while forage mixture and site did interact to affect soil nitrate/nitrite availability. Results suggest that forage mixtures could be used to improve soil function, but longer-term studies are needed to conclusively demonstrate environmental and production benefits of high-diversity forages.

The variability in herbage yields measured on 3- × 6-ft caged areas in a pasture with various forage mixtures, rotationally grazed paddocks, and fertilizer treatments was examined. The mean coefficient of variability (C.V.) between individual samples from within a [Formula: see text] paddock was 37% but ranged from 24 to 78% depending on the mixture, fertilizer treatment, and year. When sampling data taken during four or five successive grazing periods were accumulated into annual yields the mean C.V. was 25% and the range from 10 to 58%. Almost the same estimate of yield was obtained by sampling only half of the rotation paddocks within a plot as by sampling all of them, provided the total number of cages per plot was the same. When only a portion of the paddocks in a plot was sampled it was better to sample alternate ones than adjacent ones.

Forage mixtures containing urea-treated whole crop wheat (WCW) have been shown to be used less efficiently than expected by dairy cows due to low digestibility, particularly of the starch. The purpose of the present experiment was to measure the contribution of the rumen to the digestibility of diets based on grass silage or mixtures of grass silage and urea-treated WCW.

MSMA (monosodium methanearsonate) and DSMA (disodium methanearsonate) were applied to seedling orchardgrass (Dactylis glomerata L.) – alfalfa (Medicago sativa L. ‘WL-304′) and reed canarygrass (Phalaris arundinacea L. ‘Ioreed’)-birdsfoot trefoil (Lotus corniculatus L. ‘Dawn’) mixtures before grasses were beyond the three-leaf stage. MSMA and DSMA controlled foxtails (Setaria spp.), large crabgrass [Digitaria sanguinalis (L.) Scop.] and fall panicum (Panicum dichotomiflorum Michx.), but were not effective on barnyardgrass [Echinochloa crus-galli (L.) Beauv.]. The addition of 2,4-DB [4-(2,4-dichlorophenoxy)butyric acid] or bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) to MSMA or DSMA increased broadleaf weed control over that obtained with MSMA or DSMA alone. The forage mixtures tolerated 2 to 3 kg/ha of MSMA or DSMA and increased in yield when weeds were controlled. Elemental arsenic found in the forage increased in forage as the rates of MSMA or DSMA increased. Eighty-six to 96% less arsenic was found in early-than in late-treated forage.
