Silage Production

Lotus corniculatus, birdsfoot trefoil, is a Eurasian perennial legume, popular in temperate climates for pasture or hay and silage production. Its ancestry is controversial. While innumerable studies of L. corniculatus and allied species have been published, comprehensive morphological, geographical, and genetic studies are still needed. Nevertheless, there is sufficient information for a provisional analysis of the origin and relationships of this important economical species. Although sometimes defined to have diploid populations, L. corniculatus essentially appears to be tetraploid. Biochemical and genetic evidence indicates that this species is an allotetraploid. Although about a dozen diploid species have been proposed as ancestral to L. corniculatus, the evidence points strongly to four of these species. Lotus uliginosus uniquely shares a rhizomatous habit, an acyanogenic factor, and a tannin characteristic with L. corniculatus, clearly showing an especially close relationship, and reflecting the possibility that it is one of two direct parental species. Principal candidates for a second parent include Lotus alpinus, Lotus japonicus, and Lotus tenuis. A phenetic analysis presented here accords well with the hypothesis favoured in this paper that L. corniculatus arose as a hybrid of L. tenuis and L. uliginosus. Cytogenetic evidence indicates that L. japonicus is especially closely related to L. corniculatus. Flower colour in the hybrids between L. uliginosus and L. tenuis suggest maternal inheritance and that L. tenuis could have been the female parent. An evolutionary sequence is suggested in which L. uliginosus hybridized with L. tenuis followed by introgression from L. alpinus and L. japonicus. Alternatively, a prototype of L. alpinus, L. japonicus, and L. tenuis could have been the female parent of L. corniculatus, based on evidence from maternal inheritance of flower colour intensity and interactions of Rhizobium strains.

Field Germination

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.

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

Double Cross

Studies using pubescence and cyanogenesis as genetic markers indicate that a high proportion of self-seed is set when selfing is followed by pollinations with mixtures of self- and cross-pollen. Also, considerable selective fertilization occurs when pollination is with mixtures of compatible pollen. It is suggested that the incompatibility mechanism may be used for commercial production of "double-cross hybrids" of trefoil.

Selection For

Bruce birdsfoot trefoil (Lotus corniculatus L.) is a 71-clone synthetic variety developed at the Nappan Research Farm, Agriculture and Agri-Food Canada, Nappan, Nova Scotia. Bruce was developed through two cycles of mass selection for plant vigour (top and root growth) and winterhardiness, and one cycle of mass selection for re-growth vigour under grazing. In Atlantic Canada, Bruce produced more forage than the check cultivar Leo during 3 post-seeding years. It was also superior in spring growth with high first-cut herbage yields.

Good Productivity

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.

Napropamide [2-(a-naphthoxy)N,N-diethylpropionamide] applied to cranberry (Vaccinium macrocarponAit.) as a granular or wettable powder formulation at 20 kg/ha in March 1978 controlled aster (Aster subspicatusNees) and birdsfoot trefoil (Lotus corniculatusL.) without any phytotoxicity to ‘McFarlin’ cranberry vines. Earlier application in February was ineffective, and late application in April injured the vines. Napropamide 10% granular applied at 14 kg/ha in March 1979 controlled aster 90% and birdsfoot trefoil 70%, and the 50% wettable powder formulation controlled aster 90% and birdsfoot trefoil 80%. Applications of granular napropamide at 12 kg/ha in March of 1979 or 1980 controlled both weeds 70%.
