Abstract (sommario):

Around 1000 ha of cocksfoot seed are entered for certification each year. Average seed yields are 250 kg ha" for Grasslands Kara and 400 kg ha- for Grasslands Wana, but specialist growers can achieve at least another 100 kg ha-'. In the case of Wana cocksfoot yields of 700 kg ha" have been recorded.. Most of the cocksfoot seed crops in New Zealand are in the Methven area.

Abstract (sommario):

Cocksfoot (Dactylis glomerata L.) is among the most important perennial grass species sown in temperate Australia. Newly sown cocksfoot pastures were established on 5 commercial farms (sites), in the temperate high-rainfall (>600 mm annual rainfall) zone of eastern Australia. Experiments were located on these commercial farms, and were measured from September 1993 to August 1996, to compare the effect of seasonal sheep grazing management strategies with continuous grazing (control treatment) on cocksfoot herbage mass and plant frequencies. Each experiment had 8 common grazing treatments and

Background Inclusion of forage into the orchard is of great help in promoting the use efficiency of resources, while shading from trees restricts forage growth and production in the Loess Plateau of China.

Studies in the field and in a rhizotron were conducted to examine the root growth of Phalaris aquatica L. (phalaris), Dactylis glomerata L. (cocksfoot) and Lolium rigidum Gaudin (annual ryegrass). Root and tiller development of the perennial grasses in autumn was also studied. In the field, annual ryegrass developed a more extensive surface rooting system than phalaris and cocksfoot by spring in a favourable season. Early root development of annual ryegrass was poor where the first rains of the season did not occur until winter. Growth rates of annual ryegrass roots at depth were similar to ph

The 9 year 'MaxClover' experiment at Lincoln University concluded that ryegrass and white clover pastures were less persistent than cocksfoot and lucerne under dryland conditions in Canterbury. Measurements of insect pests commenced in Year 5 in response to a measured decline in sown ryegrass and white clover. The aim was to determine if there were differences in insect pressure among the different pastures. Insect pest pressure was present in all pastures from when measurements commenced until the experiment finished in Year 9. Grass grub larvae were the main pest that contributed to the decl

Abstract (sommario):

In New Zealand, subterranean clover is recommended as a companion legume in mixed swards, particularly in dryland cocksfoot-based pastures. However, establishment of cocksfoot is slower than perennial ryegrass and therefore weed ingress is more common. An experiment at Lincoln University, Canterbury showed imazethapyr applied when clover was at the 3-4 trifoliate leaf stage, and cocksfoot at the 2+ leaf stage, increased the subterranean clover content of the pastures by at least 1000 kg DM/ha, despite initial visual phytotoxicity responses.

During the research cocksfoot created 5 leaves and timothy 7 leaves. Timothy leaf blade area was almost 2 times higher than the cocksfoot. In both species found positive correlation between fertilization, the total area of blade leaves and yielding. However, there was no such

Soil water use was greater under perennials over the summer{autumn period and the soil profile was approximately 50 mm drier at the beginning of each drainage season. Following autumn rains, soil water profiles under all treatments converged, usually reaching similar water contents within 4{6 weeks. Over 4 years, soil under phalaris beca

Abstract (sommario):

Tall fescue (Festuca arundinacea Schreb., Lolium arundinceum Schreb., S.J. Darbyshire) and cocksfoot (Dactylis glomerata L.) were identified for improvement for low to medium rainfall (400–700 mm) environments where persistence of common cultivars has been unreliable. Over 200 accessions and experimental varieties of tall fescue and cocksfoot sourced from the Mediterranean basin were screened over 2 years at sites on the North-West Slopes of NSW and on the Central Highlands of Victoria, respectively. These were compared with some locally naturalised plants and most of the cultivars available i

Abstract (sommario):

The recently completed molecular phylogenetic analysis of Dactylis germplasm has provided a clear evolutionary history of the diploid Dactylis from which modern tetraploid germplasm and cultivars have evolved. This framework will allow us to use fully a wider range of both diploid and tetraploid germplasm for a more systematic improvement of cocksfoot. Germplasm of many diploid and tetraploid forms is under serious threat from habitat degradation and climate change, and many forms are currently poorly represented in genebanks. It is critical that a wide range of these forms is collected for st

Abstract (sommario):

The cocksfoot grass is a valuable early ripe forage crop with good yield and excellent feed quality. It is used to create hayfields and pastures and is a component of grasslands of meadows of almost all regions of the Komi Republic. However, the expansion of varieties adapted to the soil and climate of the North needs this valuable crop. For this purpose from 2015 to 2018 there was the research of the varieties and wild populations of the cocksfoot grass of the world collection for further use in the creation of new adaptive varieties. The experiment took place in 2015 at the experimental fiel

Abstract (sommario):

The current difficult political and economic situation generates the need to seek new sources of energy, and the solution may be to increase biomass of energy crops through using organic–mineral wastes to improve soil quality. The research objectives were to determine the effect of coal gangue (CG) and sewage sludge (SS) based organic–mineral fertilizer (OMF) application on cocksfoot growth and subsequently on biogas and methane production. First, a 6-week vegetation experiment was conducted where degraded soil (DS) taken from the edge of a sand mine in Rokitno was amended with OMF at 1% (DS +

Abstract (sommario):

Cocksfoot (Dactylis glomerata L.) is becoming increasingly important for grassland farming due to climate change, which alters precipitation and increases droughts. Although it is generally considered to be drought-tolerant, little is known about the differences between cultivars. This study aimed to investigate the effects of four different field capacity (FC) levels (80%, 60%, 40%, and rewetting to 80% after a period of 40% FC) on the yield, crude protein content, water consumption, water use efficiency (WUE), and drought susceptibility index of five European cocksfoot cultivars (cv).
