Biostimulants in the Production of Forage Grasses and Turfgrasses

In intensive and sustainable agriculture, it is not enough to use plant protection products and fertilizers, but it is also important to control plant physiological processes. The aim of this study was to determine the effect of Tytanit on Festulolium braunii (K. Richt.) A. Camus dry matter yield, photosynthetic activity and the content of chlorophyll and selected chemical compounds. The pot experiment was conducted in 2019 in a plant breeding room. Four levels of treatment were used: control with no treatment and three stimulant concentrations of 0.02%, 0.04% and 0.06% in the spraying liquid. In particular, the research included the determination of dry weight of plant roots, dry weight of plants, chlorophyll a and b content in leaf blades, maximum and actual efficiency of the leaf photosystem, coefficients of non-photochemical and photochemical fluorescence quenching, and the content of total protein, crude fiber, monosaccharides, crude fat, crude ash, Ca, Mg, P and K in the dry matter of plants. Used in controlled conditions, the stimulant contributed to an increase in most parameter values, increasing photosynthetic activity and the content of chlorophyll a and b, total protein, calcium, magnesium and potassium, but it reduced the amounts of crude fiber.

“…The characteristics of forage grass that is growing well include lush overall growth, large and dense leaves, thick and strong stems, and a stable and lush underground root system [15]. The quality of the growth conditions directly impacts the quality of forage grass, which, in turn, affects the availability of high-quality feed for the livestock industry [16]. It also indirectly affects humans' healthy intake of meat and milk protein through the adequate supply of forage grass.…”

Tolerance of Forage Grass to Abiotic Stresses by Melatonin Application: Effects, Mechanisms, and Progresses

Climate change related abiotic stress has been potentially impacting the quantity and quality of forage grass. Melatonin, a multifunctional molecule that has been found to be present in all plants examined to date, plays a crucial role in improving forage grass tolerance to both biotic and abiotic stresses. However, research on melatonin’s role in forage grass is still developing. In this review, the effects of melatonin application on abiotic stress are the primary topic, and we try to find relative mechanisms. In order to determine whether melatonin has a good effect on forage grass, we compared and summarized the adapting ability of different forage grasses under abiotic stress after melatonin application in aspects of growth and development, photosynthesis, antioxidant systems, plant hormone interactions, and ion homeostasis. According to part of the data, we found that different forage grasses exhibited varying responses to endogenous melatonin content and exogenous melatonin dose applications. Meanwhile, the regulatory mechanisms of melatonin application include the expression of chlorophyll synthesis and degradation genes, electron transport and phosphorylation genes, stress regulation pathway genes, and plant hormone synthesis genes. We propose possible future studies that can further explore the metabolic pathways of melatonin and the molecular mechanisms of melatonin regulation of abiotic stress in forage grass. Specifically, research can focus on elucidating the signaling pathways, gene expression of regulatory networks, and interactions with other plant hormones. This will provide valuable theoretical and practical guidance for adapting to climate change and forage grass development.

“…Smooth brome is characterized by high palatability and digestibility, and it is willingly consumed by animals, particularly ruminants. It has a low content of crude fiber, a higher content of fat and protein of high biological value [79,80,88]. Smooth brome is a key component of pasture mixes due to its rapid spring growth, considerable persistence on pastures and a long life cycle [81,82].…”

et al. 2024

Smooth brome (Bromus inermis L.) is a species of perennial grass with growing economic importance. Initially, this species had attracted interest as a source of animal feed. Over the years, the interest in smooth brome increased significantly due to the growing knowledge about its advantages. The aim of this study was to explore the contemporary significance of smooth brome. This plant is characterized by a high tolerance to many negative environmental factors, such as periodic droughts, low temperatures and salinity, which contributes to its constant presence in the landscape of many countries. The moderate soil requirements of smooth brome, combined with the effective use of soil resources and rational nutrient utilization, contribute to high biomass yields that can reach 13 t/ha DM. The usefulness of this grass species in various management systems has been recognized in numerous research studies. Smooth brome can generate benefits in many branches of the economy. This efficient energy plant is used in paper production, and it is also recommended for the protection of fallow land or the reclamation of degraded land. Smooth brome prevents erosion, enhances biodiversity, and provides shelter for many animal species. This species fits well into the current assumptions of agricultural policy and increasingly demanding environmental standards. According to the latest guidelines, modern agriculture should pursue economic and environmental goals simultaneously. In this context, smooth brome constitutes a valuable link in sustainable development. Due to its numerous advantages, smooth brome not only provides high-quality feed and biomass but also effectively sequesters CO2, improves soil fertility and enhances biodiversity, which makes it an important element of agriculture and environmental protection.
