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.

Dactylis Glomerata L

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

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

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.

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.

Establishment of productive stands of birdsfoot trefoil (Lotus corniculatus L.) is often difficult due to poor seedling vigour. Objectives of this study were to evaluate the relative effectiveness of in vitro selection conditions for seedling vigour and to choose the best lines for further evaluation. Birdsfoot trefoil seedlings from cvs. Leo and Upstart were selected on the basis of in vitro rate of germination at 5, 12 and 20 °C and subsequent seedling growth at 20 °C. Two cycles of recurrent selection were carried out. Progeny from both cycles of selection were evaluated under controlled and field conditions. In general, selection temperatures did not significantly affect emergence, individual shoot dry matter production or total shoot dry matter production. Emergence and total shoot dry matter yield were higher for selections within cv. Upstart than for selections within cv. Leo. Seedling vigour of cycle-2 selections was not superior to cycle-1 selections. Failure to make gains during the second cycle of selection is believed to be due to seed sterilization procedures during cycle-2 selection. Germplasms chosen for further evaluation include the 12 °C and 20 °C cycle-1 selections and the 20 °C cycle-2 selection from cv. Upstart.

Dry Matter Digestibility

Digesting forages with a prepared cellulase solution (PCS) has been shown to be a rapid method of obtaining dry matter digestibility (DMD) estimates in many species. This procedure has not been previously used to obtain DMD estimates of broadleaf birdsfoot trefoil (Lotus corniculatus L.). A broad based population consisting of 19 accessions, representing 11 countries of origin, three germplasm pools, and two domesticated cultivars of birdsfoot trefoil was evaluated. The PCS was produced from culturing Trichoderma reesei Simmons culture number QM9414. Fiber and PCS determinations were compared to an in vitro rumen fermentation (IVDMD) procedure. The fiber components measured were; neutral detergent fiber (NDF), acid detergent fiber (ADF), and hemicellulose (HEMI). The PCS procedures involved digestion using a PCS without any pre- or post-treatment (CS), acid-pepsin digestion followed by a single-stage digestion in PCS (APCS), acid detergent solution (ADS) followed by a two-stage digestion in PCS (ADSCS), and neutral detergent solution (NDS) followed by a two-stage digestion in PCS (NDSCS). All of the fiber and PCS procedures were significantly (P ≤ 0.001) correlated with IVDMD except HEMI. The CS procedure underestimated IVDMD by 199 g kg−1; however, it had the best regression coefficient (b = 0.99), had the second best correlation coefficient (r = 0.86), and required less time than the other PCS procedures. The APCS procedure provided the best estimate of IVDMD. It overestimated the IVDMD mean of birdsfoot trefoil by only 30 g kg−1 and was the most accurate (residual standard deviation (RSD) = 22 g kg−1) approach. The CS procedure is recommended when a ranking of samples is desired and actual values of DMD are not of primary interest.Key words: Fiber digestion, germplasm, in vitro dry matter digestibility, Lotus corniculatus L., Trichodenna reesei Simmons

A characteristic property of legumes is the formation of hard-stone seeds. To use such seeds for sowing, it is necessary to carry out measures to increase their seeding indicators. The article provides an overview of methods of pre-sowing preparation of seeds, priming (Seed Priming). The harvest of Birdsfoot trefoil (Lotus corniculatus L.) can contain up to 90% or more hard-stone seeds. Mechanical priming of hard-stone seeds of Birdsfoot trefoil increases their germination energy and field germination.
