Botanical composition of grasses is one of the most important indicators the biological value and quality of the obtained hay and pasture forage, the longevity of hayfi elds and pastures depend on. The issue of changing the botanical composition of agrophytocenoses is especially important in the context of global climate change, which in recent decades is also manifested in the territory of Ukraine, as it is possible to establish the most adapted species of legumes and cereals to adverse weather conditions and to identify eff ective technological methods of managing these processes for maximum conservation economically valuable species in the herbage. The purpose of the research is to establish the infl uence of diff erent ways of sowing of clover and alfalfa cereal crops agrophytocenoses on the formation of their botanical composition. Field studies have established diff erent eff ects of conventional in-line, cross-section and cross-sectional methods of sowing on the formation of botanical composition of grass mixtures of clover meadow (Trifolium pratense) varieties Sparta and Pavlyna with timothy meadow (Phleum pratense) and fenugreek multifl oral (Lolium multifl orum) and of agrophytocenoses of alfalfa of Sinyukha and Seraphima sowing varieties with reed fire (Festuca arundinacea Schreb) and middle wheatgrass (Elytrigia intermedia). For the average of four years of life of clover and alfalfa cereal crops agrophytocenoses, the highest proportion of legume component was observed with split-cross sowing – 51.6 % for Sparta, 53.1 % for Pavlyna, 60.3 % for Seraphima and 61.6 % for the Sinyukha variety. In the fourth year of life (the third year of use) of sowed leguminous-cereals agrophytocenoses, the preservation of the legume component was 14.6–15.5 % in clover-cereals grass mixtures with the Sparta variety and 16.0–16.8 % with the Pavlyna variety. In alfalfa grasslands, these indicators were 54.0–55.1 % with Seraphim and 55.0–56.2 % with Sinyukha. Among the studied varieties of clover meadow and alfalfa sowing proved better in the conditions of the Forest Steppe of western Pavlyna and Sinyukha. Cross-sectional and divided cross-sectional sowing of legumes and cereals mixtures proved to be better compared to conventional row crops in terms of conservation of economically valuable grass species.

Abstract We evaluated the stability of perennial legume and cereal grass species in artificial plant communities on permanent anti-erosion watercourses in the agroecosystems of the Belgorod region with active development of linear soil erosion. In the conditions of steppe and forest-steppe zones of the Belgorod region on permanently grassed watercourses in 2017-2019. varieties of perennial leguminous and cereal grasses: ‘Krasnoyaruzhskaya 1’ and ‘Krasnoyaruzhskaya 2’ (Medicago varia), ‘Kazatsky’ (Trifolium pratense), ‘Olshanka’ and ‘Ivica’ (Festuca arundinacea), ‘Streletsky’ and ‘Stepnyak’ (Lolium perenne)) obtained using local genetic material were studied. All varieties showed their resistance in agro-ecosystems with active development of linear erosion in the forest-steppe and steppe zones. Projective cover on watercourses in the steppe zone in all variants of experience was on average 83,4 %, in the forest-steppe zone - 86,3 %. In the third year of the tests on permanently irrigated watercourses in the steppe zone, the share of cereal and legume grass species was quite high and varied from 88 % in the variant M. varia + Onobrychis arenaria to 92 % in the variants M. varia + Bromopsis inermis and O. arenaria. In the forest-steppe zone, the share of cereal and legume grass species varied from 86 % in the variant L. perenne to 94 % in the variant L. perenne + B. inermis.

Ruminal Degradability

Forty samples of grass silages, made from the five most widely used grass species in ruminant nutrition (<I>Dactylis glomerata</I> L.,<I>Phleum pratense</I> L., <I>Lolium perenne</I> L., <I>Festuca arundinacea</I> L. and hybrid Felina) were tested in the present study. These grass species conserved by an ensiling process were compared among each other according to dry matter (DM) rumen degradability parameters (<I>a</I> = portion of DM solubilized at initiation of incubation, <I>b</I> = fraction of DM potentially degradable in the rumen, <I>c</I> = rate constant of disappearance of fraction b and ED<sub>DM</sub> = effective degradability of DM, estimated for each ingredient assuming the rumen solid outflow rates of 0.02 (ED<sub>DM2</sub>), 0.05 (ED<sub>DM5</sub>) and 0.08 (ED<sub>DM8</sub>) h<sup>–1</sup>). Based on the chemical composition of grass silages the regression equations for prediction of ED<sub>DM</sub> were evaluated. The influence of the ensiling process on dry matter degradability parameters was also assessed. The best values of ED<sub>DM</sub> were determined for <I>Lolium perenne</I> (ED<sub>DM2</sub> = 753.2, ED<sub>DM5</sub> = 631.1 and ED<sub>DM8</sub> = 567.7 g/kg DM). The best predictor was NDF (<I>R</I><sup>2</sup>-values of 0.757 (ED<sub>DM2</sub>), 0.863 (ED<sub>DM5</sub>) and 0.906 (ED<sub>DM8</sub>)). Using two predictors the accuracy level increased. The combination of CF and NDF gave <I>R</I><sup>2</sup>-values 0.892, 0.920 and 0.929 for ED<sub>DM2</sub>, ED<sub>DM5</sub> and ED<sub>DM8</sub>, respectively. The regression equations based on the most important grass species harvested in different vegetation periods seem to be a useful tool for practical use. No significant <I>P</I> < 0.05) effect of the ensiling process in relation to dry matter rumen degradability parameters was proved.

In investigations on the grass regeneration biology a special attention was paid to the formation of aerial tillers and branching pseudostolons in <i>Dactylis glomerata</i> L., <i>Festuca arundinacea</i> Schreb., <i>Festuca pratensis</i> Huds., <i>Festuca rubra</i> L., <i>Phleum pratense</i> L., <i>Lolium multiflorum</i> Lam., <i>Lolium perenne</i> L., <i>Phalaris arundinacea</i> L., <i>Arrhenatherum elatius</i> (L.) P. B., <i>Holcus lanatus</i> L., <i>Agropyron repens</i> (L.) P. B., <i>Avenastrum pubescens</i> (Huds) Opiz and <i>Agrostis alba</i> L. Aerial tillers, vegetative short ones and with partly elongated internodes as well as generative tillers formed in tufted and rhizomatous grasses. Parental raised tillers, on which aerial tillers developed, had the anatomical structure specific for grass stems. In tufted grasses, moreover, parental branching pseudostolons developed; in their cross section the arrangement of tissues specific for stolons was observed. They constituted the starting point for agglomerations of new plants rooting in soil, contrary to raised tillers. In some grass species, beside pendant roots, shorter roots grew at the base of aerial tillers; they surrounded with a ring the parent shoot in the node, thus reinforcing the connection of aerial tillers with the stem. An attention was paid to the favourable role of branching pseudostolons in the sward thickness formation. Conditions of the arrangement of tissues in the stem cross section, owing to which the rhizomatous form is developed, are discussed. The fertilization with compost or the covering with sand results in the formation of tillers resembling pseudorhizomes.

Pasture Productivity

Most pastures in Atlantic Canada are classified as permanent and contain primarily native species. Well-managed native swards have the potential of supporting profitable animal output. Productive cultivars of cool-season perennial grass species such as timothy (Phleum pratense L.), orchardgrass (Dactylis glomerata L.), tall fescue (Festuca arundinacea Schreb.), reed canarygrass (Phalaris arundinacea L.) and legumes such as white clover can increase pasture productivity in the region and ameliorate seasonal fluctuations in dry matter yield associated with native swards. Improved swards gradually revert to native species, partly because forage cultivars and mixtures are not assessed for persistence under grazing.Soil acidity and deficiencies in soil nutrients were shown to reduce herbage yield, legume content of the grazed swards and mineral content of the herbage, all of which may adversely affect livestock performance. High concentrations of K, observed in swards heavily fertilized with N, are likely to cause problems in the metabolism of Ca and Mg in lactating ruminant livestock grazing such swards.Supplemental pasture crops, including annual ryegrass (Lolium multiflorum Lam.) and Brassica species, extend the productive grazing season from approximately 4 to 7 mo, and permit the production of large quantities of biomass close to the barn.Rotational grazing and forward creep-grazing techniques at high stocking rates can improve the number of animal grazing days and average daily gains. Previous experience with grazing and exposure to pasture species before and during weaning appear to influence grazing behavior and species preference of newly weaned livestock. The use of previous grazing experience may help create the desired pasture sward or improve the efficiency of sward utilization by the grazing animal. The high rainfall climate of the Atlantic region, which promotes good herbage production, also encourages heavy and prolonged infestations of infective free-living stages of gastrointestinal parasites on pastures. Permanent pasture is the main source of initial herd infection, which then spreads to newly seeded pastures. Strategic treatments of grazing livestock with anthelmintic drugs are recommended to minimize the impact of these parasites on the productivity of grazing livestock in this region.

SUMMARYThe performance of Welsh Mountain ewes and their single Clun-cross lambs on swards of perennial ryegrass (Lolium perenne L.), cocksfoot (Dactylis glomerata L.), tall fescue (Festuca arundinacea Schreb.) and timothy (Phleum pratense L.) was studied over 3 years (1975–1977) at a site 305 m O.D. in mid-Wales. Under a rotational grazing regime at a fixed stocking rate of 25 ewes and lambs/ha, mean daily lamb live-weight gain over the 84 days experimental period from early May to late July was 24 g higher on timothy than on perennial ryegrass and tall fescue and 35 g higher than on cocksfoot. Averaged for the 3 years the mean daily lamb live-weight gains were 194, 170, 170 and 159 g on timothy, perennial ryegrass, tall fescue and cocksfoot respectively. There were, however, marked interactions with years.Ewe live-weight change varied considerably between grasses and years with cocksfoot poorer than timothy and perennial ryegrass. Mean ewe live-weight change ranged from an overall loss of 39 g/day in 1975 to a gain of 34 g/day in 1977.Differences detected in animal performance between the four grass species altered during the 84 days of the experiment. Timothy and to a lesser extent tall fescue produced better animal performance early in the season whereas perennial ryegrass came into prominence during July.The results are discussed in relation to the present and potential use of the grass species under upland conditions.

Chloride Uptake

Twelve cultivars representing eight grass species were each grown in a sand/vermiculite medium in the greenhouse, fed six solutions varying in chloride content for 140 days, and cut at lawn height. Six harvests were obtained and analyzed for chloride uptake. Visual ratings and yields indicated that the grasses tolerate relatively high chloride levels for a considerable time. Chloride uptake increased with time and increasing chloride content of the solutions. Uptake was less from alkaline than from acid solutions. Highland bentgrass (Agrostis tenuis Sibth.), Italian ryegrass (Lolium multiflorum Lam.) and timothy (Phleum pratense L.) were the least tolerant, while Norlea perennial ryegrass (Lolium perenne L.) and Kentucky 31 tall fescue (Festuca arundinacea Schreb.) were the most tolerant to chlorides. Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) were intermediate in this respect.

Five grass species (<I>Dactylis glomerata</I> L., <I>Phleum pratense</I> L.,<I> Lolium perenne</I> L., <I>Festuca arundinacea</I> L.) and the hybrid Felina (<I>Lolium multiflorum</I> L. × <I> Festuca arundinacea</I> L.), commonly used in roughages for ruminants, were harvested at different maturities of primary growth (<I>n</I> = 60) and evaluated for contents of dry matter (DM), crude protein (CP), ash, crude fat, neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL), indigestible neutral detergent fibre (INDF) and digestible neutral detergent fibre (DNDF). INDF and DNDF contents were determined by <I>in sacco</I> rumen degradation of grasses for 12 days in non-lactating cows. ADL content was found to be highly correlated (<I>P</I> < 0.05) with DNDF (<I>r</I> = –0.87) and presented a reliable (<I>R</I><sup>2</sup> = 0.78; residual mean square error of 17.65 g/kg DM; <I>P</I> < 0.0001) parameter to predict INDF contents. Over a six-week period of maturation INDF contents increased (<I>P</I> < 0.0001) in all studied grasses. It was confirmed by this study that the INDF contents of grasses, which markedly increased during maturation, could be effectively predicted from ADL contents.

Lafrenière, C. and Drapeau, R. 2011. Seeding patterns and companion grasses affect total forage yield and components of binary red clover–grass mixtures. Can. J. Plant Sci. 91: 91–97. Red clover (Trifolium pratense L.) is the most popular seeded legume for forage production in northern Quebec and Ontario because of the poorly drained soils that prevail in these regions. The objective of this experiment was to determine which seeding patterns [mixed within a row (MR), single alternate rows (1+1), or double alternate rows (2+2)] and which companion grasses (smooth bromegrass, Bromus inermis L.; tall fescue, Festuca arundinacea Schreb.; orchardgrass, Dactylis glomerata L.; or timothy, Phleum pratense L.), in association with red clover, were best for sustaining the total forage yield of a red clover–grass mixture and how these factors affect red clover and grass components. Test plots were established at Kapuskasing, ON, and Normandin, QC. At each site, two independent seedings were performed and harvested over 3 yr following the seeding year. Total dry matter (DM) yield and contribution of red clover grasses and weeds to total forage yield were measured. The MR pattern gave higher yield over both alternate seeding patterns by nearly 0.5 Mg DM ha−1 at the Normandin site and 1.0 Mg DM ha–1 at the Kapuskasing site. Neither the seeding pattern nor the companion grass species improved significantly the contribution of red clover to total forage yield beyond the second production year even though there were differences between sites. Environmental conditions, principally high precipitation in the fall, and maturity stage at harvest resulted in major differences between sites. Results from this experiment showed that tall fescue and orchardgrass could be good alternatives to timothy or bromegrass in association with red clover given that plots were still productive in the third production year and invasion by weeds was lower.

In future, grass swards need to be adapted to climate change and interactions of management and site are becoming more important. The persistence of Lolium perenne on peatland or during dry periods is limited and alternative forage species are required. We tested the performance of a modern variety of Festuca arundinacea and Phleum pratense as an alternative to Lolium perenne on clay, peat, and sandy soils. Each of these grasses was sown as main species in mixture with Poa pratensis and Trifolium repens and the mixtures were subjected to different frequencies of defoliation. Differences in yield proportions in the third year were significantly influenced by main species, site and their interaction. Remaining mass proportions of main species after three years were smallest on peat; on all sites Festuca arundinacea showed the highest persistence and largest yield, followed by Lolium perenne. Mass proportions of Phleum pratense were small on peat soils and Phleum had been replaced there by Holcus lanatus, and by Lolium perenne and Poa pratensis on the clay and sandy soils. We conclude that the choice of grass species in mixtures is a management tool to control stability and productivity of grass swards under specific site conditions.

An experiment was conducted on a fertile Walcanui silt loam in 1991/92 to examine the productivity of 4 perennial pasture grass species, Grasslands Roa tall fescue (Festuca arundinacea), Grasslands Marsden hybrid tyegrass (Lolium perenne x Lolium hybridum), Grasslands Maru phalaris (Phalaris aquatica), Grasslands Wana cocksfoot (Dactylis glomerata), and 2 binary mixtures, tall fescue plus cocksfoot and phalaris plus cocksfoot. Between July 1991 and September 1992 the highest production came from phalaris plus cocksfoot at 19.05 t DM/ha. Hybrid ryegrass, phalaris, tall fescue plus cocksfoot, cocksfoot, and tall fescue produced 17.44, 17.13, 16.96, 14.17, and 13.13t DM/ha respectively. The botanical composition of both mixtures averaged equal proportions of the sown species. The proportion of cocksfoot increased over the summer period then declined for the following autumn/winter period. The experiment shows that simple pasture grass mixtures may be highly productive. These findings support the increasing farmer practice of sowmg some pasture grasses in simple mixtures.
