Interseeding red clover (RC; Trifolium pratense L.) to winter wheat (WW; Triticum aestivum L.) is a recommended management practice for wheat growers in Ontario, as it is known to provide a host of services including a significant nitrogen credit for the subsequent crop. However, fewer Ontario wheat acres are being interseeded with RC because of challenges with nonuniform stands. A survey was developed to explore why growers use the winter wheat – red clover (WWrc) system and to evaluate the management practices being used. We received 179 responses, 142 which were from growers currently practicing WWrc and the rest were from growers who had used WWrc in the past. Of those who were currently practicing WWrc, increasing degrees of tillage, wider WW row spacing, and higher RC seeding rates showed some indication of improved RC stand uniformity, and qualitative feedback from growers in the survey supports this. It is recommended that these management practices receive formal evaluation to increase the success of the WWrc system in Ontario.

Tillage and weed management practices used during the establishment year can likely affect for age yield during the subsequent production year(s). This study was conducted as part of a long-term experiment to determine the suitability of conservation tillage practices for red clover (Trifolium pratense L.) production on a Kamouraska clay from 1988 to 1995. Red clover was underseeded with spring barley (Hordeum vulgare L.) in cropping systems including different tillage (MP: fall moldboard plow; CP: fall chisel plow; NT: no-till) and weed management (intensive, moderate, minimum) treatments applied during the establishment year. Red clover dry matter yields and weed biomass were measured twice in the subsequent forage production year. Tillage had no effect on red clover yields in 3 out of 7 yr. Yields were 16% greater with NT in 1 yr and 52% with MP tillage in 3 yr compared with other tillage treatments. Weed response to tillage was consistent over years. Dicot weed biomass increased as tillage intensity was reduced. Monocot biomass was much less with NT than with MP or CP treatments. Red clover yield was 11% greater with intensive weed management, but this yield increase was not associated with differences in dicot or monocot biomass during the forage production year. Red clover yield gain with intensive weed management would need to be weighed against economical and environmental costs to determine the relevance of increased herbicide use in a short-term cereal/forage rotation. Key words: Red clover (Trifolium pratense L.), conservation tillage, no-till, forage legume

The use of winter legumes in southern Brazil is hindered by the slow growth of these species during establishment exposing soil surface to erosion. Introduction of these species along with spring wheat (Triticum aestivum L.) was studied as a means of increasing ground cover during their initial establishment period, without reducing wheat grain yield. Two experiments were conducted in nearby areas, one in each year. Birdsfoot trefoil (Lotus corniculatus L.), red clover (Trifolium pratense L.) cultivar Quiñequelli, white clover (T. repens L.), and arrowleaf clover (T. vesiculosum Savi) did not reduce cereal yield in either year. Wheat yield was reduced by intercropped red clover cultivar Kenland and by subclover (T. subterraneum L.) in the first year. No grain yield differences due to intercropping with any legume were detected in the second year, when rainfall was below normal. Intercropping with wheat showed to be a practical alternative to enhance ground cover at establishing forage legumes.

Trifolium Pratense L

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.

Trifolium Pratense L

The composition of the volatile fraction of two important forage legumes from Italian sub-alpine N.E. pastureland, namely Trifolium pratense L. subsp. pratense (red clover) and T. repens subsp. repens (white clover) were investigated. The volatile oil was obtained from the fresh aerial parts by steam distillation and analyzed by GC/FID and GC/MS. The oil yield was 0.018 and 0.021% (weight/fresh weight basis) for T. pratense and T. repens, respectively. Several classes of compounds were found in both the oils, including alcohols, aldehydes, ketones, terpenes, esters, hydrocarbons, phenolics and acids. Qualitative and quantitative differences were found.
