“…The components of temporary grass-legume mixtures in temperate climate are Medicago sativa L., Medicago x varia T. Martyn, Trifolium pratense L. and highly productive grass species, including Festulolium braunii (Richt.) A. Camus, all species of the genus Lolium and Dactylis glomerata L. [8,9]. These mixtures, compared to pure-sown species, are characterized by higher and more stable yields, especially in the case of more frequent periods of drought [10].…”

The study was conducted to evaluate the influence of silicon application on the botanical composition of grass–legume mixtures as well as the nutritional value of individual species and mixtures. The two-factor field experiment was established in a split-block arrangement. The two grass–legume mixtures, consisting of Dactylis glomerata, Festulolium braunii and Trifolium pratense or Medicago x varia and grass mixture—Dactylis glomerata, Festulolium braunii and Lolium perenne, were sown on arable land. Silicon foliar and mineral NPK fertilization was applied in three variants: NPK (non-Si-fertilized), NPK+Si (Herbagreen), NPK+Si (Optysil). Changes in the botanical composition in the sward of mixtures during the study period were influenced by the competitiveness of individual plants and weather conditions, whereas the effect of foliar fertilization with silicon was only slightly marked. The nutritional value of individual species of grasses and legumes varied over the years and also depended on the application of silicon. The greatest content of crude protein (CP), irrespective of the species and variant of silicon fertilization, was noticed in years with no drought. Our research confirmed the beneficial effect of silicon fertilization, independent of weather conditions, on the CP content and on the reduction of crude fibre (CF), neutral detergent fibre (NDF) and acid detergent fibre (ADF) in plants, especially when Herbagreen was applied. The nutritional value of the mixtures under applied silicon fertilization depended on botanical composition. In the conditions of low rainfall, a large share of F. braunii and an approximately 20% contribution of T. pratense resulted in a higher content of CP. These results may be used in the fertilization practices of temporary grassland for enhancing nutritional value, especially crude protein content, and on the reduction of fibre in the sward.

“…The fodder obtained from a unit of area can be assessed by the quantity or quality of the harvest. According to Staniak and Harasim [49], and Olszewska [74], forage quality is influenced by many factors: sward species composition, plant development stage, soil moisture and nutrient abundance, and weather conditions.…”

“…No clear effect of drought on carbohydrate content in the hybrid was found [49,76]. The high carbohydrate content of Festulolium braunii predisposes this species to form mixtures with high-protein legumes, e.g., limpet, alfalfa [74,76,82]. Forages with a high proportion of water-soluble carbohydrates improve protein digestibility and reduce nitrogen losses, they also have good digestibility, which results in good development of cattle [83,84].…”

The Usefulness of Mixtures with Festulolium braunii for the Regeneration of Grassland under Progressive Climate Change

The climate warming and changes in weather patterns in Europe are negatively affecting the structure of grassland swards. The disappearance of valuable forage grasses can be observed. Therefore, in order to keep grassland productivity high, high-yielding grasses of good quality that are resistant to changes in the weather are being sought. At the moment there are few publications which present the long-term influence of changing weather conditions on meadow sward structure and its fodder value. This study aimed to assess the suitability of grass mixtures with Festulolium braunii for grassland renewal by full tillage on organic soil, taking into account atmospheric conditions. The experiments were carried out in the years 2009–2018 on a meadow complex located on organic soil in the Randow river valley, near Ramin (Germany). Grassland restoration was carried out by the method of full cultivation in three experiments with different proportions of Festulolium braunii and Lolium perenne (the existing grassland was eliminated and seeds of a new grass mix were sown). The meadow experiments were established using the method of random blocks in four repetitions Detailed studies included: floristic composition of meadow sward, fresh and dry mass yields, and content of: crude protein, soluble sugars, raw fiber, and net energy NEL (net energy lactation) concentration. Festulolium braunii, Poa pratensis, Dactylis glomerata, and Phleum pratense proved to be more resistant to low temperatures in winter and excess water in spring than Lolium perenne. The largest production potential of fresh and dry mass was found in mixtures with a high content of Festulolium braunii Festulolium braunii tolerates varied and unfavorable weather conditions (frosts during snowless winters, spring frosts and waterlogging, and droughts) very well and provides a stable good quality sward yield (favourably affected the carbohydrate and protein content of the sward). Lolium perenne, on the other hand, decreases its share in the sward under unfavorable weather conditions.

“…Compared to pure-sown species, simple grass–legume mixtures sown on temporary grasslands are characterized by higher and more stable yields, as well as having a weaker response to adverse environmental conditions than monocultures, especially in the case of more frequent periods of drought [ 5 , 6 ]. The components of these mixtures are generally composed of highly productive grass species, including all of the genus Lolium and especially Medicago sativa or Medicago x varia [ 7 , 8 ].…”

Drought and allelopathic conditions impact the germination of seeds of grass and legume species used in mixtures on grassland. This study evaluated the effects of drought and Medicago sativa root extracts at different pH levels on the germination and characteristics of seedlings of Lolium perenne and selected Medicago species. Two experiments were carried out: the first explored the effects of drought induced by PEG solutions (0.0, −0.3, and −0.6 MPa) under silicon (Si) application; the second studied the influence of Medicago sativa root extracts (12 and 24 g/100 mL H2O) and variable pH solutions (control, 5.0, and 6.5) on seed germination. Germination was carried out on Petri dishes for individual species and in two-species mixtures. The drought conditions did not affect the germination capacity of seeds, but it increased the dry weight of the seedlings of the tested species. The application of silicon decreased the root length of the seedlings of all species, independent of the germination conditions. The higher concentration of M. sativa root extract combined with the studied pH solutions had an inhibitive impact on the germination capacity of L. perenne. Our findings revealed that the lower concentration of M. sativa root extract had a beneficial effect on the morphological features (length of roots and leaves, fresh and dry weight) of the seedlings when germination was carried out separately for both species. In the mixture, the effect was especially marked for L. perenne (only in terms of the root length and fresh weight of seedlings). The applied root extracts in combination with the acidic pH conditions limited the germination capacity and growth of the seedlings of L. perenne the most when germination was performed separately. It was concluded from this study that silicon application did not improve the germination capacity of seeds under drought conditions, whereas the germination of L. perenne seeds in a mixture with M. sativa mitigated the negative allelopathic effects of M. sativa root extracts on the seed germination capacity and morphological features of seedlings of L. perenne.
