The objective of this study was to isolate and characterize lactic acid bacteria (LAB) with low carbohydrate tolerance from rumen fluid and to elucidate their probiotic properties and the quality of fermentation of Medicago sativa L. and Trifolium incarnatum L. silage in vitro. We isolated 39 LAB strains and screened for growth in MRS broth and a low-carbohydrate supplemented medium; among them, two strains, Lactiplantibacillus plantarum (Lactobacillus plantarum) RJ1 and Pediococcus pentosaceus S22, were able to grow faster in the low-carbohydrate medium. Both strains have promising probiotic characteristics including antagonistic activity against P. aeruginosa, E. coli, S. aureus, and E. faecalis; the ability to survive in simulated gastric-intestinal fluid; tolerance to bile salts; and proteolytic activity. Furthermore, an in vitro silage fermentation study revealed that alfalfa and crimson clover silage inoculated with RJ1 and S22 showed significantly decreased pH and an increased LAB population at the end of fermentation. Also, the highest lactic acid production was noted (p < 0.05) in LAB-inoculated silage vs. non-inoculated legume silage at high moisture. Overall, the data suggest that RJ1 and S22 could be effective strains for fermentation of legume silage.

Selective Process

Silica is present in soil and culture solutions as undissociated monosilicic acid (H4Si04) and this suggests that its uptake by plants would be a passive, non-selective process. We have earlier reported (Jones and Handreck 1965) that the overall uptake by oats (Avena sterilis cv. Algerian) can be accounted for simply in terms of the concentration of monosilicic acid in the soil solution and the amount of water transpired. Thus, when grown in two potted soils containing 7 and 67 p.p.m. Si02 in solution, oat plants at maturity contained 28 and 274 mg Si02 per plant respectively, having transpired 3�9 litres of water and produced 7�0 g of dry matter. The concentration of silica in xylem sap from oats is similar to that in the external solution. When Trifolium incarnatum (L.) (crimson clover) was grown in these two soils the plants had transpiration ratios of 510-530 but contained silica in concentrations which were only 5-10% of those in oats. This suggests that T. incarnatum has some means of excluding silica from the tops; we have examined this further by measuring the concentration of silica in the xylem sap.

Replicated field trials indicated that tarnished plant bug (TPB), Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae) attained relatively-high densities on hybrid vetches, Vicia sativa L. X V. cordata Wulf cv ‘Cahaba White’ and ‘Vantage’, lower densities on crimson clover, Trifolium incarnatum L. cv ‘Dixie,’ and particularly-low densities on subterranean clover, Trifolium subterraneum L. cv ‘Mt. Barker’. Densities of TPB were also relatively low on an additional 10 types of subterranean clover, including 7 cultivars representing T. subterraneum, 1 cultivar of T. brachycalycinum Katznelson and Morley, and 3 of T. yanninicum Katznelson and Morley. Field longevity trials indicated that late-instar and adult TPB lived longer when caged on crimson clover than on hybrid vetch, which in turn supported better survival than did subterranean clover. When adult TPB were caged on hybrid vetch or subterranean clover with or without floral and fruiting structures, there was no evidence that the presence of these structures prolonged TPB survival on either crop. In laboratory choice tests with flowering and fruiting shoots of three cover crops, TPB preferred crimson clover over hybrid vetch, which in turn was more attractive than subterranean clover. When shoots were presented after reproductive structures had been excised, there was no statistically-significant preference by TPB.

Abstract The effectiveness of soil erosion control of various vegetative aisle covers was evaluated using Universal Soil Loss Equation (USLE) type plots. ‘Appalow’ sericea lespedeza (Lespedeza cuneata (Dumont) G. Don ‘Appalow’), crimson clover (Trifolium incarnatum L.), and perennial ryegrass (Lolium perenne L.) aisle treatments and a clean till plot were established on a 5% slope Typic Paleudult soil. Previously established ‘Indian Magic’ crabapple (Malus ‘indian magic’) and silver maple (Acer saccharium L.) were grown parallel to the slope in the center of each plot. Runoff from the clean till aisle resulted in the greatest sediment concentration, runoff volume, and sediment runoff. Crimson clover and perennial ryegrass runoff was similar. The ‘Appalow’ lespedeza aisle cover had the highest runoff volume of any vegetative aisle cover. However, runoff sediment concentration and sediment runoff were least from ‘Appalow’ lespedeza covered aisles.

Fall-planted cover crops of hairy vetch (Vicia villosa Roth), Austrian winter pea (Pisum sativum subsp. arvense L. Poir), and crimson clover (Trifolium incarnatum L.) were each followed by spring-planted 'Sundance' summer squash [Cucurbita pepo var. melopepo (L.) Alef.] and 'Dasher' cucumber (Cucumis sativus L.). Squash and cucumber crops were followed by fall 'Florida Broadleaf mustard green [Brassica juncea (L.) Czerniak] and 'Vates' collard (Brassica oleracea L. Acephala group), respectively. The same vegetable sequences were also planted without benefit of cover crop. Three nitrogen (N) rates were applied to each vegetable crop. Squash following winter pea and crimson clover produced greater yields than did squash planted without preceding cover crop. Cucumber following crimson clover produced the greatest yields. No cover crop effect was noted with mustard or collard. Elimination of N fertilizer resulted in reduced yields for all crops, but yields of crops with one-half the recommended N applied were generally comparable to those receiving the full recommended rate.
