Percent Nitrogen

Sweetclover (Melilotus officinalis L.), alfalfa (Medicago sativa L.), and red clover (Trifolium pratense L.) were grown to determine their value for returning nitrogen to the soil at two locations in northeastern Saskatchewan from 1956 to 1960. Yields of dry matter and nitrogen in the top growth and in the roots were determined for each crop at rive stages of growth. The legumes were seeded m association with a fertilized and an unfertilized companion crop of wheat (Triticum aestivum L.).Sweetclover produced the greatest yield of top growth at all harvest dates. The root weights of alfalfa and red clover had surpassed those of sweetclover by July 15 (full-bloom stage) and September 15 (mature-seed stage), respectively. Percent nitrogen in the top growth of the legumes ranged from 1.87 to 2.61% on September 15 of the first year and from 2.58 to 2.89% by June 15 of the second year. After June 15, a sharp decline in percent nitrogen of the top growth occurred, especially in sweetclover. Percent nitrogen of the root growth of sweetclover also declined rapidly after June 15, while that of alfalfa and red clover increased.If sweetclover, alfalfa or red clover were used for green manure in late June or early July of the second year, a return of 70 to 90, 60 to 95 and 50 to 75 kg N/ha, respectively, would have occurred. If a crop of hay or silage was removed and only the stubble used for green manure, the average nitrogen returns to the soil from sweetclover, alfalfa and red clover would have been 10, 20, and 15 kg N/ha, respectively.Fertilizer increased the yield of the companion crop and reduced the yield of the legumes.

Trifolium Pratense L

The objective of this study was to investigate the changes that take place in nutrient values of red clover (Trifolium pratense L.) cv K-27 at different stages of growth in the second and the third cut. The samples from different stages of growth: mid-bud stage, around 60% flowering and full flowering were investigated for crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), digestible dry matter (DDM), dry matter intake (DMI), relative feed value (RFV), total digestible nutrients (TDN), net energy-lactation (NEl), net energy-maintenance (NEm) and net energy-gain (NEg) content. Higher content of crude protein was found in the third cut (262.1 g kg-1 of DM) than in the second cut (260.8 g kg-1 of DM) in the first stage of development. TDN, DDM, DMI, RFV, NEl, NEm and NEg were calculated according to the appropriate equations adapted from common formulas for forages. The stage of plant development has a significant influence on the chemical composition and the relative feed value of red clover. The achieved results show that adequate maturity stage for cutting might be at mid-bloom stage, when crude protein content, NEl, NEm and NEg content are high.

The Impact

A 3-yr field study was conducted on a Dark Brown Chernozemic soil to assess the impact of the date of sweetclover (Melilotus officinalis Lam.) incorporation and tillage implement used for incorporation on succeeding spring wheat (Triticum aestivum L.) yields. During year 1 wheat was underseeded to sweetclover. In year 2 the clover was incorporated on either 15 June, 1 July or 15 July. Five tillage implements were evaluated (a) mouldboard plough (b) rotavator (c) tandem disc (d) offset disc and (e) deep tillage cultivator. In the spring of year 3, each treatment was seeded to wheat. Over the duration of the study only small and usually insignificant differences (P ≥ 0.05) in year 3 wheat yields occurred related to incorporation implement. Date of sweetclover incorporation during year 2 was a significant factor when the 15 June incorporation resulted in 6 and 17% greater wheat yields than 1 July or 15 July, respectively. Sweetclover dry matter production, measured at the early date of incorporation was 32% less than the two later incorporation dates. Mineral nitrogen, determined to a depth of 60 cm in year 3 immediately following wheat seeding, was 82, 75 and 62 kg ha−1 for the 15 June, 1 July and 15 July incorporation dates, respectively. It was concluded that the implement selected for sweetclover incorporation is not critical, however the timing of plough down is important and should be relatively early in the growing season in order to maximize succeeding grain production.Key words: Sweetclover, incorporation, green manure

Red clover (Trifolium pratense L.) is the second most important perennial forage legume, after alfalfa. It is a significant source of proteins, which are essential in the diet of domestic animals, especially ruminants. The objective of this study was to determine the most important characteristics of dry matter quality (crude proteins, structural carbohydrates, fats and minerals) in three varieties of red clover (K-17, Kolubara and Una). The characteristics were monitored, per individual cuts, during one production cycle of red clover, i.e., in the period 2004- 2006. Highest contents of crude protein in all three test years were obtained in the second cut. Significantly increased contents of crude proteins (18.32%) and potassium (K-2.53%) were found in the red clover cultivar Una developed in Novi Sad. Significantly increased values of both cellulose fiber fractions (NDF, ADF) were registered in the second year of growing. The highest content of minerals was determined at the beginning of the growing season in the first and second year (8.68% and 8.52%, respectively). Here it should be mentioned that the contents of basic biogenous elements, phosphorus and potassium, were within the expected optimum range.

Physiographic Regions

Red clover (Trifolium pratense L.) is one of the most important temperate legume species, used to lessen the lack of forage during the critical fall-winter period in Rio Grande do Sul, RS, Brazil. However, its utilization has been restricted mainly because of its lack of persistence. This work evaluates the dry matter yield and persistence of red clover half-sib progenies in two physiographic regions of RS: "Depressão Central", in Eldorado do Sul and "Encosta Superior do Nordeste", in Veranópolis. Experiments were carried out for two growing seasons and results were compared to two red clover commercial checks, Qüiñequeli and Estanzuela 116. The region of Veranópolis was more adequate for red clover forage production, enabling better yield and persistence. The best check for both locations was cultivar Estanzuela 116. At Eldorado do Sul persistence was highly affected and some progenies were superior to the best check. At Veranópolis the best check was very productive, with good persistence. The best progenies at both locations were selected to be propagated and submitted to additional recurrent selection cycles.

The present work is an attempt to assess the effect of biostimulants of various origins and nitrogen regime on yield performance, chlorophyll content, protein content and soluble carbohydrate in red clover. A field experiment was arranged as a randomized subblock design (split-plot) in Poland in August 2013. The following factors were examined: type of biostimulant; nitrogen application rate: 0 (control) and 30 kg. ha-1. Biostimulants significantly increased red clover biomass yields. All the examined biostimulants contributed to an increase in the amount of organic components in red clover dry matter. Nitrogen applied at the rate of 30 kg. ha-1 significantly increased red clover yield, chlorophyll content in red clover leaves and protein compounds but it also significantly reduced soluble carbohydrates in the dry matter of test plants.

Short Term

Late-maturing cultivars of red clover (Trifolium pratense L.) and timothy (Phleum pratense L.) may be grown in short-term rotations with other crops and harvested for hay and silage. Harvesting forage in mid-summer is often advantageous for field curing, but the quality of mature forage may be low. We studied how harvests at different developmental stages affected yield, composition of herbage, and species persistence. The late-maturing single-cut red clover cultivar Altaswede and late timothy cultivar Farol were grown alone and in combination with and without applied N. Total forage, and red clover and timothy dry matter yields, increased between the first (27 June) and third (11 July) dates of harvest. Timothy grown alone or combined with red clover and fertilized with N produced greater forage yields than red clover alone or red clover + timothy without applied N. The in vitro digestibility of dry matter declined from 670 to 625 g kg−1 and crude protein from 134 to 109 g kg−1 between 27 June and 11 July. Water soluble carbohydrates in forage were low (36–66 g kg−1) in cuts 1 and 2. Macronutrient and micronutrient concentrations were generally highest at the first date of harvest on 27 June. Nutrient concentrations in cut 2 were similar for the three harvest schedules. We conclude that growing late-maturing single-cut red clover combined with late timothy produced high yields with good nutritional quality even at advanced stages of maturity. Single-cut red clover persisted for the first production year making this combination suited for short-term rotations that involve late harvesting of the primary growth.

The performance of nine double-cut and three single-cut red clover (Trifolium pratense L.) cultivars was studied at five locations in Atlantic Canada. The single-cut clovers survived relatively well at all locations while the double-cut clovers did not survive well at one location during the first winter. An analysis of data for total dry-matter yield from five environments, i.e., location-year combinations, showed that the single-cut clovers outyielded the double-cut clovers in Newfoundland but yielded lower at the other locations. Among the double-cut cultivars, Florex, Lakeland, Tapiopoly, and Violetta were found to be desirable cultivars because they had a high mean yield and did not yield lower than the population average at any of the five environments. A large cultivar-environment interaction variance was detected for the double-cut cultivars; therefore, at least 15 test environments are required in future trials in order to detect a yield difference of 6% by multiple comparison procedures.Key words: Trifolium pratense L., stability

Five legumes [hairy vetch (Vicia villosa Roth.), barrel medic (Medicago truncatula Gaerth.), alfalfa (Medicago sativa L.), black lentil (Lens culinaris Medik.), and red clover (Trifolium pratense L.)] were interseeded into sweet corn (Zea mays L.) at last cultivation when sweet corn was at about the V9 (early) or blister (late) stage. The effect of legume interseeding on sweet corn yield, and late-season dry-matter and N yields of aboveground portions of the legumes was determined. Sweet corn yield was not affected by legume interseeding. In 1993, legume dry-matter yields were 1420 kg·ha–1 interseeded early and 852 kg·ha–1 interseeded late. Nitrogen yields were 49 kg·ha–1 interseeded early and 33 kg·ha–1 interseeded late. In 1994, dry-matter yields were 2760 kg·ha–1 interseeded early and 1600 kg·ha–1 interseeded late. Nitrogen yields were 83 kg·ha–1 interseeded early and 50 kg·ha–1 interseeded late. In 1993, barrel medic was the highest-yielding legume with dry matter at 2420 kg·ha–1 and N at 72 kg·ha–1 interseeded early, while red clover yielded the lowest with dry matter at 340 kg·ha–1 and N at 12 kg·ha–1 interseeded late. In 1994, dry-matter and N yields ranged from 4500 and 131 kg·ha–1, respectively, for early interseeded barrel medic to 594 kg·ha–1 and 16 kg·ha–1, respectively, for late interseeded red clover.

Clover Pasture

Many farmers are sowing mixed swards containing chicory (Cichorium intybus), plantain (Plantago lanceolata), red clover (Trifolium pratense) and white clover (T. repens) (hereafter termed herb and clover mix). This herb and clover mix has comparable annual dry matter (DM) production to perennial ryegrass white clover pasture (rye/wc), however, it has a different pattern of growth, producing more DM during summer and autumn. The herb and clover mix also has a higher nutritive value and is able to support greater rates of animal production, especially over summer, than rye/ wc in both sheep and cattle. The herb and clover mix is most suited to a rotational grazing interval of 3-4 weeks to an 8 cm residual height, with no winter grazing. When managed appropriately the herb and clover mix is able to persist for at least 2 years and up to 5 years under both sheep and cattle grazing. Keywords: Cichorium intybus, Plantago lanceolata, Trifolium pratense, Trifolium repens, legume, perennial, nutritive value.
