According to a greennouse experiment, the relative flooding tolerance of nine legumes was as follows: birdsfoot trefoil (Lotus corniculatus L.), white clover (Trifolium repens L.), and strawberry clover (Trifolium fragiferum L.), 20 days; red clover (Trifolium pratense L.), alsike clover (Trifolium hybridum L.), and alfalfa (Medicago media Pers.), 15 days; sweetclover (Melilotus alba Desr.) and cicer milk vetch (Astragalus cicer L.), 10 days; and sainfoin (Onobrychis viciaefolia Scop.), 5 days. Yellowing of leaves was an excellent indicator of flooding damage. Growth of herbage and roots were arrested when the soil became waterlogged, but plants persisted quite well if flooding was not prolonged beyond the tolerance level indicated.

The Relationship

Experiments were conducted to determine the relationship between clover phyllody and strawberry green petal diseases in Eastern Canada. Clover phyllody virus from naturally infected ladino clover (Trifolium repens L.) in Quebec was transmitted by Aphrodes bicinctus (Schrank) to strawberry (var. Redcoat and Sparkle) and ladino clover. Symptoms on infected strawberry were typical of green petal. Strawberry plants, naturally infected with green petal, were obtained from Kentville, N.S., La Pocatière, Que., and Charlottetown, P.E.I. The virus was transmitted to ladino clover, red clover (Trifolium pratense L.), and strawberry (vars. Redcoat, Guardsman, Senator Dunlap, and Grenadier) by A. bicinctus and to ladino clover and aster (Callistephus chinensis Nees) by Macrosteles fascifrons (Stal).On the basis of leafhopper transmission and symptomatology, it is concluded that clover phyllody and strawberry green petal diseases in Eastern Canada are caused by the same virus.

Root Lesion Nematodes

Foliage yields of red clover (Trifolium pratense L.), alfalfa (Medicago sativa L.), white clover (Trifolium repens L.), and birdsfoot trefoil (Lotus corniculatus L.) were reduced by root-lesion nematodes [Pratylenchus penetrans (Cobb, 1917) Filip. and Stekh, 1941]. Foliage yields generally decreased with increased infestation levels. Significant yield reductions were recorded at the time of first cutting for white clover and birdsfoot trefoil, but not until several cuts later for red clover and alfalfa. Mean yields of birdsfoot trefoil, red clover, alfalfa, and white clover infested with 7,500 nematodes per pail were 50, 73, 83, and 93%, respectively, of control yields.

Sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} and RO-13-8895 {acetone-O-[d-2-[p-[(α,α,α-trifluoro-p-tolyl)-oxy]phenoxy]propionyl]oxime} were evaluated for quackgrass [Agropyron repens (L.) Beauv. ♯ AGRRE] control in ‘Norcen’ birdsfoot trefoil [Lotus corniculatus (L.)], ‘Monarch’ cicer milkvetch [Astragalus cicer (L.) Hook.], and ‘Arlington’ red clover [Trifolium pratense (L.)]. None of the herbicide treatments applied to weed-free legumes 3, 15, and 30 cm tall reduced crop ground cover or seed yield. Postemergence treatments of sethoxydim and RO-13-8895 applied to quackgrass in the one- to four-leaf stage, at rates from 0.56 to 1.1 kg ai/ha, gave control of 57 to 91% in September of the seedling year. Legumes in all postemergence herbicide-treated plots produced more seed than legumes in untreated plots, regardless of time of application. Sequential applications of sethoxydim, RO-13-8895, or fluazifop {(±)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy]propanoic acid} at 0.14 plus 0.14 kg ai/ha gave more effective quackgrass control and greater legume ground cover than single applications at 0.28 kg ai/ha.

Seed Yields

The effects of various row spacings and seeding rates on seed yield and certain seed yield components, viz, florets per head, seed set, seeds per pod, were studied on single seedings with three successive seed crops of red clover (Trifolium pratense L.), alsike clover (T. hybridum L.), and birdsfoot trefoil (Lotus corniculatus L.). Alsike clover and birdsfoot trefoil produced the highest yields at the narrow 15-cm spacing with successive decreases to the 60-cm spacing. The taller-growing and later-blooming, single-cut red clover was slightly more adaptable to varying spacings with the highest yields at 30- and 45-cm spacings, and slightly lower yields at the 15- and 60-cm spacings. All three crops competed successfully with weeds at the narrow spacings (15 and 30 cm). All three crops were able to compensate within limits in the 2nd and 3rd seed yr for differences in stand caused by different seeding rates. Seeding rates of 2.2 and 4.5 kg/ha were most favorable. Certain components of yield, e.g., florets per inflorescence, percent seed set, and seeds per pod, did not vary within years and are primarily affected by rainfall, soil fertility, pollinator populations and favorable pollinating weather. Differences in seed yields were attributable to total production of flower heads or racemes.

Forage chicory (Cichorium intybus L.) was grown alone and in combination with various grasses and legumes for three production years to determine growth, botanical composition, and persistence. Chicory mixed with grasses and legumes produced greater yields than chicory alone. Mixtures of orchardgrass (Dactylis glomerata L.) + white clover (Trifolium repens L.), timothy (Phleum pratense L.) + alfalfa (Medicago sativa L.), and timothy + red clover (Trifolium pratense L.) in combination with chicory produced the highest dry matter yields. Persistence of chicory was adequate; it survived for three production years in the cold-winter region of Atlantic Canada. Including chicory in grass/legume swards improved the seasonal distribution of herbage and increased late season production.

Small plot experiments and field scale trials were conducted to determine the establishment and growth of sod-seeded alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.), white clover (T. repens L.), and birdsfoot trefoil (Lotus corniculatus L.) in fine sandy loam soils on Prince Edward Island. Both pasture and hayfield managements were included. A John Deere PowrTill 1500 drill was used for sod-seeding and various combinations of grazing, herbicides, and clipping were used for vegetation suppression during establishment of the legumes. Sod-seeded red and white clovers established the best and were the most productive species. It was estimated that in the postseeding year sod-seeding of clovers resulted in yields comparable to stands fertilized with 100-150 kg N∙ha−1 annually. Trefoil and alfalfa had variable establishment and usually made a limited contribution to sward productivity. Timothy sod-seeded in conjunction with red clover, white clover or alfalfa established satisfactorily with all three legume species used.Key words: Pasture renovation, red clover, white clover, alfalfa, birdsfoot trefoil, sod-seeding
