Red clover (Trifolium pratense L.) offers a number of advantages as a forage legume, but is constrained by poor persistence under grazing. The objective of this research was to test the growth and persistence of 18 populations among a wider set of 142 New Zealand and overseas accessions of red clover, in a mixed-sward replicated plot trial under rotational grazing by cattle in the Manawatu. We also measured plant morphological trait expression in a row trial using samples of the same red clover populations evaluated in the plot trial. Most red clover populations showed a marked decline in growth score after two years under grazing. The new variety 'Grasslands Relish' showed significantly (P

Agricultural Areas

In September 1977 and 1978, color infrared (CIR) aerial photographs of mixed agricultural areas (approx. 132.7 km2) near Vernon and Carp, Ontario, and of forage legume test plots at Ottawa were taken at a scale of 1:6000. Extensive ground surveys were conducted within 2 wk after the photographic flights to verify CIR images of alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.), trefoil (Lotus corniculatus L.), vetch (Vicia spp.) grasses and their mixtures in the original transparencies. A number of photographic image characteristics of legumes and grasses have been illustrated by which a reliable identification and subsequent quantification of legume components were made, particularly in fields that showed decline of a crop or when the individual components grew as separate patches in the same field. Photo-interpretation difficulties existed in distinguishing the components in a very uniformly mixed crop and recently cut fields.

Trifolium Pratense L

Red clover is the most important forage legume in the Czech Republic. It is an unassuming species to climatic and soil condition, is suitable for mixtures with grasses and it is above other grassland species in forage quality. The most serious problem of red clover in grasslands is its lack of persistency (2–4 years). Considering of red clover growing area on arable land decrease and area of permanent grasslands increases, becomes persistency of varieties important attribute. The persistency of all Czech varieties was evaluated on the basis of dominance proportion investigation after 3 winters. Assessed varieties were established in mixture with grasses (60:40%). Significantly most persistent varieties were Amos 4n (24.5%), Dolina 4n (20.25 %) and Radegast 4n (19.25%). Varieties of Alsike clover were not significantly different from varieties of red clover.

Although the persistency of red clover (Trifolium pratense L.) can be a problem when grazed in mixed and pure stands, it is still regarded as a valuable source of high quality summer feed in some farming systems. Vegetatively reproductive red clover selections offer promise to solve this persistency problem but their growth, perennation, reproductive ability and productivity have not been investigated in New Zealand farming systems. This paper is an overview of a 4 year research programme involving nine experiments investigating these areas. The vegetatively reproductive red clovers evaluated were Astred, F2419 and Gualdo. There was no difference between Astred and Grasslands Pawera, a crown type red clover, in the total herbage accumulated over the first growing season under 4, 6 and 8 week grazing frequencies and lax and hard grazing intensities. After 3 years of grazing, significantly more Astred parent plants were alive compared to Pawera when rooted plantlets were counted as parent plants after one year. Varying numbers (0-66 plantlets/m2/yr) of rooted plantlets were produced by Astred in mixed and pure swards. More rooted plantlets were established per parent plant under wet surface soil conditions. Astred produced 57% of its autumn rooted plantlets on primary stems developed in September, or branches off these stems. Comparisons of the growth and morphology of Astred, F2419 and Gualdo are presented. Red clover selections that are vegetatively reproductive offer benefits to New Zealand farming systems and could solve some of the persistency problems currently experienced with red clover.

Continental Climate

A study was conducted across Canada to compare the herbage productivity of fodder galega (Galega orientalis Lam.) to that of traditional forage legumes, in order to assess its agricultural potential. Trials were established at latitudes ranging from 45 to 56°N with longitudes from 52°W (St. John's, Newfoundland) to 120°W (Dawson Creek, British Columbia). Herbage productivity was monitored for a maximum of 3 production years. The establishment characteristics of Gale fodder galega were comparable to those of Apica and Beaver alfalfa (Medicago sativa L.) and Altaswede red clover (Trifolium pratense L.), and somewhat superior to those of Dawn Alsike clover (T. hybridum L.) and Leo trefoil (Lotus corniculatus L.). Anik alfalfa (M. falcata L.) was far less uniform and vigorous in its establishment than any of the other species. The average annual dry matter yield of fodder galega ranked third among the seven legumes when averaged over the nine sites; it produced 5545 (SE 95) kg ha−1 compared to 3931 (SE 72) kg ha−1 for Dawn alsike clover, the lowest-yielding crop, and 6673 (SE 114) kg ha−1 for Apica alfalfa, the highest-yielding. The cumulative dry matter yields indicated that Gale galega is at least as well adapted across Canada as the other legumes, except possibly at Saskatoon where the M. sativa alfalfas were far superior to all the other legumes in their ability to establish and thrive. The performance characteristics of Gale fodder galega indicate that it has considerable agricultural potential as an additional, perennial, herbage legume for many regions of Canada, except in the semi-arid continental climate of the central Prairies where its growth may be limited by high air temperature and/or insufficient soil moisture. Key words: Fodder galega, Galega orientalis Lam., goat's rue, herbage production, forage legume

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.
