Cool Climate

Two studies determined the effect of birdsfoot trefoil harvest managements on persistence, productivity, and species composition under cool summer growing conditions. Single and double cut managements were harvested at 10, 50, and 100% bloom; triple cuts and simulated grazing were also evaluated. Double cut harvest management produced considerably more dry matter yield (DMY) in the first production year, but its advantage over single cuts in the second year depended on bloom at harvest. Harvesting at 10% bloom for single (and perhaps double) cuts appears to be the best system based on DMY, trefoil content, and stand density.

Birdsfoot trefoil (Lotus corniculatus L. ’Viking’) was seeded directly into a predominantly orchardgrass (Dactylis glomerata L.) sward following overall or banded applications of paraquat (1,1′-dimethyl-4, 4′-bipyridinium ion, as dichloride salt) or glyphosate [N-(phosphonomethyl)glycine, as isopropylamine salt] to determine the degree of sward control necessary for stand establishment without tillage. Effects of the herbicide treatments and the seeding on botanical composition and dry matter production were determined by a vertical intercept technique and by hand separations of harvests into botanical components. Trefoil establishment was proportional to the degree of sward control during the seeding year. Little trefoil was established by direct seeding without herbicides. The banded herbicide treatments were less effective than overall herbicide applications for trefoil establishment. Trefoil yield obtained following overall application of paraquat was approximately 65% of that obtained following overall glyphosate treatment.Key words: Dactylis glomerata, glyphosate, Lotus corniculatus, herbicide, no-tillage, paraquat

In field trials in 1998–2000, ten varieties of the world collection of birdsfoot trefoil (Lotus corniculatus) were evaluated for herbage and hay yields. In all the years of testing yields from three cuttings and total annual production were evaluated. In 1999, seed yield was also recorded. As a control, alfalfa (Medicago sativa) variety was included in the experiment. The test varieties showed good productivity in the first and especially in the second year of testing, most of them exceeded alfalfa in herbage yield in individual cuttings and in total productions. As for hay yield, the differences were not so great. Local varieties showed very good productivity, predominantly in herbage yields. Of foreign varieties, the best herbage, hay and seed yielder was the Hungarian variety Puszta. There were no statistical differences in seed yield between the varieties. The yields were, however, relatively low.

Two new isosynthetic strains of birdsfoot trefoil (Lotus corniculatus L.), containing low or high concentrations of tannin, were tested using in vitro and in sacco digestibility techniques. The high tannin (HT) strain contained an average of five times more tannin on a dry matter basis, than the low tannin (LT) strain. After 24-h in vitro digestion, by a rumen inoculum, there was less (P < 0.01) dry matter disappearance (45.7 vs. 54.4%) from the HT strain. Also, the development of gas pressure was lower (P < 0.01) and production of volatile fatty acids less (P < 0.05) with the HT strain than with the LT strain. Average dry matter loss from four replicated nylon bags was also lower (P < 0.01) for the HT strain than for the LT strain after 8, 12, and 24 h of incubation in rumen. These data indicate that a LT strain of birdsfoot trefoil might improve the forage digestibility. Key words: Birdsfoot trefoil, tannin, digestibility

A 3-year study on the stages of growth of birdsfoot trefoil (Lotus corniculatus L.) at harvest showed that the dry matter yield increased significantly, in the spring growth, with advance in maturity up to the midbloom stage. The highest annual yield was obtained, however, when birdsfoot trefoil was harvested at the full bloom stage both in the spring and summer growth. Maximum protein yield per unit of land was also obtained at the full bloom stage. In the spring forage, the percentages of crude protein, cell content, cell wall, lignocellulose, lignin, cellulose, ash and phosphorus and in the summer forage, the percentages of crude protein, lignocellulose, cellulose, ash and phosphorus decreased significantly with maturity. For all other constituents in both forages, the variations did not reach the level of significance. The accumulation of food reserves in the roots of birdsfoot trefoil in the fall was not influenced by the stages of growth at harvest.Key words: Lotus corniculatus L., growth stage, nutrient reserves, dry matter yield, forage quality, birdsfoot trefoil

Rhizobium Strain

The growth and nodulation of two birdsfoot trefoil (Lotus corniculatus L.) cultivars, Empire and Leo, during the year of establishment were studied in the field. Plants were inoculated with each of four Lotus rhizobia strains. Four weeks after seeding, about 92% of the plants bore nodules. After 7 weeks practically all plants were nodulated and nitrogen was being fixed. Plant dry weights and dry matter yields were greatest with Rhizobium strain 95C11 which formed large nodules on each host. With strain P, many small nodules were formed and yields were lower.

The degree and longevity of quackgrass [Agropyron repens(L.) Beauv.] control provided by autumn applications of pronamide [3,5-dichloro(N-1,1-dimethyl-2-propynyl)benzamide] was influenced greatly by alfalfa(Medicago sativaL.) stand density, as well as by rate of application and soil type. When applications were made to a field with a sparse alfalfa stand (10 to 20 crowns/m2), quackgrass yields were reduced the year following pronamide application, but quackgrass reinfested the plots the second year after treatment. Quackgrass yields one and two seasons following autumn treatment with 2.2 kg/ha pronamide were 1480 and 3890 kg/ha compared to 4480 and 4870 kg/ha for control plots. Annual applications of pronamide were necessary to maintain quackgrass control in the sparse alfalfa stand. Pronamide application to a vigorous, dense alfalfa stand (40 to 50 crowns/m2) provided quackgrass control which persisted into the second year after treatment. Quackgrass control ratings one and two seasons after application of 1.1 kg/ha pronamide were 100 and 90%. Pronamide treatments reduced first cutting quackgrass yields, and increased first cutting alfalfa yields. Treatment of the sparse alfalfa stand with 2.2 kg/ha pronamide resulted in first cutting alfalfa and quackgrass yields of 2420 and 990 kg/ha compared to 1430 and 3940 kg/ha for controls. Treatment of a dense alfalfa stand with 1.1 kg/ha pronamide resulted in first cutting alfalfa and quackgrass yields of 3850 and 300 kg/ha compared to 1710 and 1660 kg/ha for controls. Total herbage yields from all cuttings were either slightly decreased when fields with sparse alfalfa stands were treated or remained constant or slightly increased when more dense alfalfa stands were treated. Pronamide applied with potash as the carrier was as effective as when applied in water. Pronamide treatment resulted in increased crude protein concentration in first cutting herbage at all locations in all years. Crude protein concentration in first cutting control herbage ranged from 13.3 to 16.1%. Crude protein concentration in first cutting herbage from plots treated with 1.1 kg/ha pronamide ranged from 17.7 to 20.6%, depending on year and location. In vitro digestible dry matter (IVDDM) concentrations were increased by most rates of pronamide in first, second, and third cutting herbage. IVDDM for first cutting control herbage was 51.4% compared to 61.3% for herbage treated with 2.2 kg/ha pronamide. Acid detergent fiber concentration in first cutting herbage was not affected by pronamide.

Interseeding alfalfa (Medicago sativa L.) into a silage corn (Zea mays L.) companion crop can increase the yield and profitability of forage production and reduce the risk of nutrient and soil loss from cropland, but unreliable establishment of alfalfa hampers the adoption of this practice on dairy farms. This study evaluated plant survival, foliar health, and dry matter yields of two alfalfa varieties when established in corn sown at populations ranging from about 47,500 to 100,000 plants per ha−1 and when treated with prohexadione (PHD), PHD followed by fungicide and insecticide (PHD-FI), or not treated with agrichemicals. The plant density of alfalfa during establishment was adversely impacted by above average precipitation and high corn populations, but substantially improved by PHD-FI treatment, which limited alfalfa etiolation, disease, and defoliation. First-cut dry-matter yields of interseeded alfalfa after corn were maximized at a stand density of approximately 200 plants m−2 or 850 stems m−2 and total first year yield exceeded conventionally spring-seeded alfalfa by 59 to 75%. Overall, our results indicated that PHD-FI treatment promoted good establishment and subsequent forage production of interseeded alfalfa. Applications of PHD-FI must, however, be fine-tuned, and additional management practices must be developed to ensure both good yields of corn silage and reliable establishment of interseeded alfalfa, especially during wet growing conditions.

Two grazing trials conducted with Friesian cows in mid lactation showed milk yields were higher on birdsfoot trefoil (Lotus corniculatus)-dominant pasture (19.8 and 16.7 l/cow/day) than on white clover-dominant (17.8 and 15.4 l/cow/day) or ryegrass-dominant (13.0 and 11.7 l/cow/day) pastures. Increased milk production on the Lotus and clover was attributed to the higher nutritive value of the legume-based pasture compared with the ryegrass, and to higher dry matter intakes. Cows grazing Lotus also had improved feed conversion efficiency compared with those grazing either ryegrass or clover, indicating that the presence of condensed tannins in the Lotus may have contributed to the improved efficiency. Milk protein concentration was consistently higher on the Lotus (3.36 and 3.35%) than on the ryegrass (3.15 and 3.21%) or clover (3.30 and 3.21%) in both experiments, while milk fat levels were lower in Experiment 1. While Lotus increased milk yield and milk protein concentration, its potential as a forage legume for dairy cows also depends on annual herbage production and the determination of how best to utilise it in a farm system.
