Analysis of dry matter yield structure of forage grasses

An average dry matter yield structure (three cuts per growing season) in relation to agronomically valuable characteristics of six forage grass species and a year of herbage utilization was studied over the period of 1989–2002 in Lithuania. The most productive species of the first cut of two years of herbage utilization were Phleum pratense (P < 0.01) and Festulolium hybrids (P < 0.05) (average dry matter yield were 7.42 and 6.66 t/ha, respectively), moderately productive – Festuca pratensis, Dactylis glomerata and Lolium perenne (5.58, 5.42 and 5.20 t/ha), significantly lower (P < 0.01) yielding was Poa pratensis (4.19 t/ha). During two years of herbage utilization Dactylis glomerata produced significantly (P < 0.01) higher dry matter yield of aftermath – 7.30 t/ha. Other grass species were ranked in the following order: Festulolium hybrids 5.85 t/ha, Festuca pratensis 4.94 t/ha, Poa pratensis 4.57 t/ha, Lolium perenne 4.48 t/ha, and Phleum pratense 3.92 t/ha. Dactylis glomerata and Poa pratensis distinguished by the highest aftermath percent in the structure of the annual dry matter yield (57.7 and 52.2%). Phleum pratense formed an especially poor aftermath – only 34.6%. An average annual dry matter yield data analysis of two years of herbage utilization over the period of 1989–2002 showed that Dactylis glomerata and Festulolium hybrids were most productive (P < 0.01) species.

Ruminal Degradability

Forty samples of grass silages, made from the five most widely used grass species in ruminant nutrition (Dactylis glomerata L.,Phleum pratense L., Lolium perenne L., Festuca arundinacea 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 (a = portion of DM solubilized at initiation of incubation, b = fraction of DM potentially degradable in the rumen, c = rate constant of disappearance of fraction b and EDDM = effective degradability of DM, estimated for each ingredient assuming the rumen solid outflow rates of 0.02 (EDDM2), 0.05 (EDDM5) and 0.08 (EDDM8) h–1). Based on the chemical composition of grass silages the regression equations for prediction of EDDM were evaluated. The influence of the ensiling process on dry matter degradability parameters was also assessed. The best values of EDDM were determined for Lolium perenne (EDDM2 = 753.2, EDDM5 = 631.1 and EDDM8 = 567.7 g/kg DM). The best predictor was NDF (R2-values of 0.757 (EDDM2), 0.863 (EDDM5) and 0.906 (EDDM8)). Using two predictors the accuracy level increased. The combination of CF and NDF gave R2-values 0.892, 0.920 and 0.929 for EDDM2, EDDM5 and EDDM8, 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 P < 0.05) effect of the ensiling process in relation to dry matter rumen degradability parameters was proved.

Resistance of common European grasses to diesel oil and petroleum pollution is not well-known. Therefore, this study aimed at determining the level of resistance of selected grasses to pollution by diesel and petroleum using the pot experiment. The achieved results were compared with those determined for grasses grown on the non-polluted soil. Soil pollution with the tested products was found to significantly decrease the yield of all grasses, with the decrease being lower upon soil pollution with petroleum than with diesel oil. The most resistant to the pollution with diesel oil and petroleum were Phleum pratense L., Lolium perenne L. and Lolium × hybridum Hausskn. The degradation of particular groups of polycyclic aromatic hydrocarbons (PAHs) depended on their chemical properties, on the type of pollutant and grass species. The greatest degradation was determined in the case of BTEX, C6–C12 benzines as well as 2- and 3-ring hydrocarbons, whereas the lowest in the case of 5-and 6-ring hydrocarbons and C12–C25 oils. The most useful species in the remediation of soils polluted with diesel oil and petroleum turned out to be: Lolium perenne L., Lolium × hybridum Hausskn and Phleum pratense L., whereas the least useful appeared to be: Festuca rubra, Dactylis glomerata L. and Poa pratensis L.

Ammonia Exchange

Abstract. Species diversity in grasslands usually declines with increasing input of nitrogen from fertilizers or atmospheric deposition. Conversely, species diversity may also impact the build-up of soil and plant nitrogen pools. One important pool is NH3/NH4+ which also can be exchanged between plant leaves and the atmosphere. Limited information is available on how plant-atmosphere ammonia exchange is related to species diversity in grasslands. We have here investigated grass species abundance and different foliar nitrogen pools in 4-year-old intensively managed grassland. Apoplastic pH and NH4+ concentrations of the 8 most abundant species (Lolium perenne, Phleum pratense, Festuca pratensis, Lolium multiflorum, Poa pratensis, Dactylis glomerata, Holcus lanatus, Bromus mollis) were used to calculate stomatal NH3 compensation points. Apoplastic NH4+ concentrations differed considerably among the species, ranging from 13 to 117 μM, with highest values in Festuca pratensis. Also apoplastic pH values varied, from pH 6.0 in Phleum pratense to 6.9 in Dactylis glomerata. The observed differences in apoplastic NH4+ and pH resulted in a large span of predicted values for the stomatal NH3 compensation point which ranged between 0.20 and 6.57 nmol mol−1. Three species (Lolium perenne, Festuca pratensis and Dactylis glomerata) had sufficiently high NH3 compensation point and abundance to contribute to the bi-directional NH3 fluxes recorded over the whole field. The other 5 grass species had NH3 compensation points considerably below the atmospheric NH3 concentration and were thus not likely to contribute to NH3 emission but only to NH3 uptake from the atmosphere. Evaluated across species, leaf bulk-tissue NH4+ concentrations correlated well (r2=0.902) with stomatal NH3 compensation points calculated on the basis of the apoplastic bioassay. This suggests that leaf tissue NH4+ concentrations combined with data for the frequency distribution of the corresponding species can be used for predicting the NH3 exchange potential of a mixed grass sward.

Number Of Stems

Based on three-year results of a ﬁeld experiment evaluating aboveground biomass production and the number of stems of above-ground shoots of grass species (Lolium perenne, Dactylis glomerata, Festuca pratensis) grown in a 200×200 mm layout in two water regime variants (normal and reduced – 50% of precipitation) and further in two variants of mowing intensity (meadow – 3 mowings, grazing – 5 mowings per year), the following has been ascertained. The most productive species on averages of the two moisture regimes is Dactylis glomerata, Lolium perenne and Festuca pratensis have fodder weight signiﬁcantly lower by 20.8% and 22.6% (meadow var.) and 16.9% and 21.9% (grazing var.). Reduction of moisture signiﬁcantly decreased the above ground biomass weight in case of meadow exploitation in Dactylis glomerata −41.2%, in Lolium perenne by −9.9% and in Festuca pratensis −33.5%. In case of grazing exploitation, the inﬂuence of “drought” on production was less pronounced. Dactylis glomerata provided the same output, in Lolium perenne there was a decrease of −15.7% and in Festuca pratensis −11.9%. Reduction of precipitation signiﬁcantly decreased shoot formation particularly in case of meadow utilization in Lolium perenne −23.7%, Dactylis glomerata −34.7% and Festuca pratensis −20.5%. In case of grazing utilization, reduction in the number of pseudostems due to “drought” was lower – in the order of the above species – 27.1% – 4.6% – 9.6%. Generally, compared with meadow utilization, grazing utilization decreases fodder production in both moisture regimes and increases the number of above-ground shoots.

Experiments were carried out under laboratory conditions in Department of Grass Science and Greenland Shaping in 2002-2004. Studies included six experiment series on Petri dishes set by means of complete randomization method in four replications. Following species were tested: Festulolium, Festuca pratensis, Lolium perenne, Phleum pratense and Poa pratensis making one or two-species combinations. Fifteen seeds of two species were arranged alternately in 1- centimeter distance on a Petri dish. Objects where seeds germinated with no neighborhood of other species (30 seeds on a dish), were control. The filter's humidity on Petri dishes was maintained by wetting it with distilled water. Achieved results revealed significant influence of blastokolins of tested grass species on seed germination and initial seedling growth. Secretion of germinating Festulolium seeds showed the highest activity. Reaction of tested grass species to allelochemicals varied. In reference to control objects, Phleum pratense among tested species was distinguished with the highest susceptibility to allelochemicals released during seed germination.

Twenty grass populations were evaluated for dry matter yield, N content, P content, organic matter content, organic matter digestibility and winterhardiness. Of these populations, Agropyron intermedium was most suitable for a hay crop on a well-drained irrigated soil. Agropyron trichophorum, Bromus inermis, and Phalaris arundinacea were lower-yielding alternatives that had a satisfactory N content and good digestibility. Elymus angustus shows promise as an irrigated hay crop and should be evaluated further. The usefulness of the following populations was limited by one or more of these factors: low yield (Y), low N content (N), low digestibility (D) and lack of winterhardiness (W): Dactylis glomerata ’Kay’ (Y,N,D), Dactylis glomerata ’Chinook’ (Y,N,W), Elymus sibiricus (Y), Festuca arundinacea ’Kenmont’ (Y,N,W), Festuca elatior ’Trader’ (Y,N), Phleum pratense (Y,N,D), Poa ampla ’Sherman’ (N,D), Poa bulbosa cv.

Different Depths

In this study, we investigated the influence of soil cultivation method on the productivity and quality of pasture grass fodder. We found that increasing the depth of cultivation from 8–10 cm to 20–22 cm (using surface tillage with disk implements) improved the productivity of all the grass species studied – Phleum pratense, Lolium perenne, Festuca orientalis, Dactylis glomerata, Bromus inermis, Phalaris arundinacea, Festuca rubra – by an average of 2%–3% at an LSD05 of 0.30 t ha−1, over a period of 3 years. On average, the most important factor influencing the production of 1 ha of dry mass appeared to be the species of grass, accounting for 57% of the variation. The depth of soil tillage was also important, accounting for 43% of the variation. Of all the species studied, the highest productivity was exhibited by Lolium perenne (0.35 t ha−1 of dry weight). Increasing the soil cultivation depth led to an increase in the content of crude protein and albumen (0.9%–1.1%). According to the analysis of organic matter content and digestibility of the fodder, across the different depths of soil cultivation, the early ripening species Dactylis glomerata, and the average ripening species Festuca orientalis, Lolium perenne, and Bromus inermis, performed best. Considering the different depths of soil cultivation, Lolium perenne [154 g; surface tillage (disking) 8–10 cm] and Festuca orientalis (152 g; ploughing 20–22 cm) provided the most fodder units with digestible protein.
