Cultivar Description

Tapani is a 21-clone diploid synthetic cultivar of red clover (Trifolium pratense L.). It was developed by phenotypic selection at Agriculture and Agri-Food Canada, Crops and Livestock Research Centre, in Charlottetown, Prince Edward Island, and at the Soils and Crops Research and Development Centre in Quebec City, Quebec. The original material for this strain was selected from collections made in old stands of red clover in three Atlantic Provinces of Canada. Tapani is early flowering and winterhardy. In Atlantic Canada, Tapani yielded an average of 109% of the check cultivar Marino over three production years. This cultivar has superior re-growth potential with high second-cut herbage yield.

Potato (Solanum tuberosum L.) producers on Prince Edward Island often underseed red clover (Trifolium pratense L.) into barley (Hordeum vulgare L.) crops so as to have a forage crop in the third year of the 3-yr rotation of potatoes-grain-forages. Some producers would like to plant an annual legume that could be underseeded in barley to improve soil organic matter levels in a 2-yr rotation of barley-potatoes. We examined, over 3 yr (1996–1998), the effect of herbicides commonly used in barley on perennial red clover and annual berseem clover (Trifolium alexandrinum L.) underseeded in barley. Based on clover plant stand after herbicide application, both red clover and berseem were killed by herbicide mixtures containing dicamba and were severely injured by bromoxynil. Red clover was severely injured by thifensulfuron/tribenuron mixture whereas berseem clover was only slightly injured. MCPA-Na generally caused little injury to either clover species whereas MCPB/MCPA caused less injury to red clover than to berseem clover. Clover yield in the fall reflected level of injury noted during the season. Key words: Red clover, berseem clover, underseeded clover, herbicide, dicamba, MCPA–Na

Trifolium Pratense L

Alfalfa (Medicago sativa L. ’Saranac’), red clover (Trifolium pratense L. ’Lakeland’), and timothy (Phleum pratense L. ’Climax’) were grown at two locations on Charlottetown fine sandy loam soils in Prince Edward Island. The pH values of the soils were 5.6 and 5.7, respectively. The three levels of lime were 0, 2.24 and 4.48 metric tonnes/ha and the Mo treatments included no Mo, Mo added as foliar spray and Mo added to the soils. In the first sampling, applications of 0.44 kg Mo/ha as foliar spray to soil limed to pH 5.9 and 6.3 in the three crops resulted in tissue Mo concentrations of greater than 10 ppm which when fed to livestock could produce Mo toxicity. With soil applications of 0.88 kg Mo/ha, tissue Mo concentrations of greater than 10 ppm occurred only in alfalfa and red clover limed to soil pH 5.6, 5.9 and 6.3. The tissue Mo levels in the second sampling decreased sharply when compared to those in the first sampling. The differences in Mo concentrations in second, third and fourth samplings were very small. There was a significant interaction (Mo × lime) because the increases of Mo concentration in red clover due to liming were much greater at higher rates of Mo than at lower rates of Mo. In the case of a suspected Mo deficiency, addition of about 0.2 kg Mo/ha as foliar spray or of 0.4 kg Mo/ha applied to the soil should alleviate a Mo deficiency problem. Residual effects at these levels of Mo should last for 2–3 yr from the crop sufficiency point of view. Molybdenum applied as foliar spray increased timothy yields by 15–17% at one location.

Research was carried out at the Lithuanian Research Centre for Agriculture and Forestry’s (LAMMC) Joniškėlis Experimental Station on a clay loam Endocalcari Endohypogleyic Cambisol. The study was aimed to explore the aboveground mass of perennial forage legumes: red clover (Trifolium pratense L.) and lucerne (Medicago sativa L.), and their mixtures with festulolium (x Festuliolium), used as green manure, qualitative parameters and compatibility with cereals on the basis of nutrients nitrogen (N), phosphorus (P) and potassium (K). The deficiency of other nutrients (P, K) and intensity of green manure mineralization can lead to N absorption. It has been determined that winter wheat takes one kg of N together with 0.2 kg P and 0.6 kg K. Spring wheat requires a similar amount of P but a higher amount of K. Average winter wheat grain yield can be 4.0 t ha-1 on a clay loam Cambisol in organic cropping system. NPK content – 134 kg ha-1 is needed for such productivity (grain + straw). This content is lower for spring winter growing. P:N and K:N ratios are more favourable in perennial forage legume mixture with festulolium, as compared to legume alone. To obtain grain yields of 4 t ha-1 of winter wheat and 3 t ha-1 of spring wheat in balanced organic crop rotation it is sufficient to apply 3.0 and 2.0 t ha-1 DM of pure legume mass as green manure. “Cut-and-carry” fertilisers do not satisfy the wheat demand for P.

The objective of this experiment was to: 1) examine the degree of influence of hereditary factors and conditions of growth (region of cultivation, season of growth and type of cultivation) on the phenotypic variance of leafiness in breeding populations of red clover; 2) quantify heritability and experimental variances in order to assess the opportunities for red clover breeding for improved leafiness. Five genotypes of red clover (four synthetic breeding populations and variety Sofia 52) were screened in the study. Among the factors studied as environmental variables, the season of growth had the strongest effect on the leafiness of red clover. In second vegetation of the life cycle of plants there was a significant additive genetic variance (hns 2 = 0.31) of the trait of leaf proportion in the fresh forage and the recurrent phenotypic selection for this criterion could be used in the breeding for leafiness in this species. It can be concluded from the results in this experiment that a higher degree of heritable genetic variation of leafiness must be searched for in connection with the variation of additional characteristics - thickness of stems, rates of formation and growth of stems, growth features related to regrowth (secondary growth) and age of sward (plants) and probably to persistence of genotypes.

Azur is a diploid cultivar of red clover [Trifolium pratense (L.)], which was selected for vigor and growth habit in the year of seeding. In forage trials conducted in Québec, Azur was superior in dry matter yield to check cultivars, particularly in trials harvested in the second production year. In trials in Ontario and the Atlantic provinces, Azur was numerically superior in dry matter yield to the check cultivar, but not significantly so (P < 0.05).

The red clover (Trifolium pratense L.) cultivar, AC Charlie, is a diploid of the early or double-cut type. It was developed by two cycles of mass selection for persistence and vigour. Forage yields after severe winter conditions indicate that AC Charlie is more winterhardy than Florex in Atlantic Canada. It is similar in maturity to Florex and 3–4 d later than Marino.

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
