“…These reports were confirmed by the results of our research. According to Buxton (1996) (Purwin et al, 2016;Staniak, 2016). Our studies showed that, regardless of the level of soil moisture, more WSC was collected by grasses than by legumes, as was confirmed by Dewhurst, Fisher, Tweed, and Wilkins (2003).…”

Legume–grass mixtures showed a weaker response to adverse environmental conditions than to monocultures. A yield decrease due to the scarcity of water is well documented, while the impact on the food value is inconsistent. Therefore, we undertook studies to assess the impact of water deficit in the soil on the content of the nutrients in alfalfa and Festulolium grown in monoculture and in mixture. A pot experiment was carried out in 2012–2014 in a completely randomized design, with four replications. The research was carried out at two levels of soil moisture: 70% field water capacity FWC (optimal conditions) and 40% FWC (drought stress). We found that the effect of drought stress on the food value of alfalfa and Festulolium was smaller than on the yield. Water deficit caused a significant yield decrease, the biggest in alfalfa in monoculture. Drought stress significantly reduced the content of crude fibre, the contents of crude protein and crude fat tended to increase. The influence of stress on water‐soluble carbohydrates content was not determined. Nutrient content was varied depending on a species. Introducing alfalfa as a component to a mixture with Festulolium caused a significant yield increase and improved the nutritional value of dry matter.

“…Carbohydrate concentrations increased in the third-cut herbage. Similar results were reported by other authors who noted considerable variations in the WSC content during the growing season (Ciepiela 2014, Purwin et al 2016). According to Griggs et al (2005), the WSC content of grasses is highest in spring, lower in summer, and it increases again in autumn.…”

“…Protein content and energy value are critical factors in qualitative evaluations of roughage for cattle. These parameters vary considerably and are influenced by numerous factors, including the species composition of the sward, the growth stage of plants, weather conditions, season and time of day (Andrzejewska et al 2013, Mäkiniemi et al 2016, Purwin et al 2016, Staniak 2016, Staniak and Harasim 2018. Roughage deficient in protein and energy has to be supplemented with concentrate and specialty feed additives, which significantly increases costs and decreases production profitability (Huhtanen and Broderick 2016).…”

A field experiment was performed in 2011–2013. The aim of the study was to determine the effect of different proportions of Medicago media in mixtures with Festulolium braunii on the yield and feed value of green fodder, including the content of crude protein (CP) and water-soluble carbohydrates (WSC), and the carbohydrate-to-protein ratio. It was found that alfalfa had a high competitive advantage over Festulolium. In the second and third year of full utilization, alfalfa was the predominant species in the tested mixtures regardless of the proportion of sown seeds. The mixtures with alfalfa were characterized by high and stable dry matter yields and high protein content, whereas Festulolium significantly increased the content of WSC and improved the WSC:CP ratio. The evaluated mixtures had a higher feed value than pure-sown components. The results of the study indicate that Festulolium mixtures with a lower proportion (30% and 50%) of alfalfa are characterized by a higher feed value.

“…The value of grassland forage is determined by the content of organic components (protein, crude fiber, sugars), minerals and organic matter digestibility. The chemical composition of grasses varies and depends on the species and variety [1], the development stage, the course of meteorological conditions [2] and can be modified by the applied fertilization [3,4]. Unilateral and long-term fertilization with one or two mineral nutrients can have adverse effects on the soil environment (a decrease in the content of Ca, Mg and other elements, a decrease in pH and depletion of soil microbial life) in addition to the quality of the obtained yields (changes in the botanical composition of the sward and the chemical composition of the plants) [5].…”

“…The effect of fertilizers and biostimulants in field studies is more visible and easier to interpret when testing them on a single plant species. In meadow studies, diploid or tetraploid cultivars of perennial ryegrass are most often selected for this purpose [1,4,11,12]. Perennial ryegrass (Lolium perenne L.) is a very popular species of the forage grass group in temperate climates [13,14].…”

Article infoOne of the elements of modern plant fertilization systems is soil biostimulants. Like fertilizers, they provide plants with nutrients, and thanks to the content of additional substances (e.g. seaweed extracts, amino acids), plant development is affected. The aim of this study is to compare the effect of selected soil biostimulants and traditional P+K+Ca fertilization on changes in the content of crude protein (CP) and water soluble sugars (WSC) in perennial ryegrass (Lolium perenne L.) cv. Anna. The research was conducted over a two-year period at the Experimental Station of the Department of Grassland and Natural Landscape Sciences at the Agricultural Experimental Station of Poznan University of Life Sciences. The two-factor experiment was set up in a randomized block design with three replications. The first factor was fertilization with biostimulants (Physio-Mescal G18, PRP-SOL, EM-1 (Effective Microorganisms), EM-1+Ca) and standard mineral fertilizers (P+K+Ca). Nitrogen fertilization (0 and 200 kg•ha -1 ) was applied as a second factor. The biomass of perennial ryegrass was evaluated for CP and WSC. The experiment showed that the application of Physio-Mescal G 18 and PRP-SOL, as well as EM-1+Ca, resulted in a significant increase in the CP and WSC content in perennial ryegrass compared to the control and the object fertilized with standard P+K+Ca fertilizers. Positive effects on the growth of the plant CP content were noted for two biostimulants: PRP-SOL and Physio Mescal G18. The ryegrass sward from the PRP-SOL-applied object contained 7% more CP compared to the control object, while that from the Physio Mescal G18 object contained 6% more. A very good effect of WSC accumulation was also obtained in the case of the sward from the PRP-SOL and Physio Mescal G18 treatments. In both cases, the determined WSC content was above 141 g⋅kg -1 DM, a difference in content from the control of as much as 6%. In addition, nitrogen fertilization applied at the annual rate of 200 kg•ha -1 significantly increased the CP content and decreased the WSC content, which worsened the CP/WSC ratio. The results of the two-year study showed that the incorporation of soil biostimulants, i.e. Physio-Mescal G 18 and PRP-SOL, into fertilizer practice makes it possible to obtain high-quality roughage for livestock.
