Effect of Tytanit on Selected Physiological Characteristics, Chemical Composition and Production of Festulolium braunii (K. Richt.) A. Camus

Abstract

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.

Assessment of the Impact of Magnesium and Nitrogen Fertilization on Two Species of Grasses Used as Horse Feed

“…In turn, ADF fraction values were comparable to the results obtained by the above authors and it complied with the feed requirements provided by Brzóska and Śliwi ński (2011) [56]. F. braunii plants in the first growth were characterized by higher concentrations of magnesium, phosphorus and potassium compared to L. multiflorum by 0.08, 0.13 and 1.95 g•kg −1 dry matter, respectively, but the values of Mg, P and K content in F. braunii plants were in accordance with those obtained in Sosnowski and Truba's [57] studies.…”

“…The crude protein (CP) content was determined using the Kjeldahl method (Kang et al, 2023). The crude fat (EE) content was determined using the Soxhlet extraction method (Sosnowski and Truba, 2023). The acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents were determined using the normal detergent fiber method (Van Soest et al, 1991).…”

“…The soluble carbohydrate (WSC) content was determined using the anthrone colorimetric method (McDonald and Henderson, 1964). The crude ash (Ash) content was determined using the high-temperature burning method in a muffle furnace (Sosnowski and Truba, 2023). The relative feeding value (RFV) was calculated according to the method described by Kang et al (2023).…”
