The level of cereal yields and the quality of these yields depend, to a large extent, on a crop management system, the genetic potential of a given cultivar, but also on factors that may cause damage to plants or a reduction in yield. Such factors include fungal diseases of cereals, which may cause a reduction in yield by 15–20%, and in extreme cases even by 60%. The main factors determining the occurrence of these pathogens are the weather conditions during the growing season of plants, crop rotation, the previous crop, the soil tillage system, and nitrogen fertilisation. Fungal diseases of cereals limit plant growth and development, as well as reduce grain yield and quality. This paper reviews the literature on fungal diseases of cereals.

Products derived from wheat grains are an important source of protein in the daily diet of people in many parts of the world. The biological value of protein is determined by its amino acid composition and the proportions of the individual amino acids. Synthesis of these compounds in wheat grains is influenced by genetic factors, as well as habitat conditions and the agrotechnology applied in cultivation. The aim of this study was to assess the effect of production technology (integrated, intensive) on the grain yield and the content amino acid profile of protein in common and durum wheat grain. Field research was conducted at the Experimental Station IUNG-PIB in Osiny (Poland) in two growing seasons. It was found that grain yield significantly depended on the weather conditions in the years of harvesting and genotype, but did not depend on the production technology. On the other hand, the protein content and their amino acid composition depended significantly on the production technology and genotype. A significantly higher content of protein substances was found in durum wheat grain. Increasing the intensity of production technology had a positive effect on the total protein content and the content of individual amino acids, both exogenous and endogenous. The amino acid limiting the biological value of protein contained in grains of both wheat species was lysine, and the deficiency of this amino acid was significantly lower in grain protein from intensive than integrated cultivation technology.

The main anti-nutritive substances present in rye grains include alkylresorcinols, water-soluble pentosans, and trypsin inhibitors. The content of these compounds in the grains can be influenced by genetic factors, habitat conditions and the crop management technology used in cultivation. The aim of the study was to determine the variability of the concentration of anti-nutritive compounds in rye grains depending on the variety, weather conditions and production technology. The field research was conducted at the IUNG-PIB Experimental Station in Osiny (Poland) in three growing seasons 2010/2011, 2011/2012 and 2012/2013. The experiment was located on lessive soil, on plots of 45 m² in three replications. The first factor was the type of production technology (integrated and intensive), while the second was a variety of winter rye. Two hybrid varieties (Brasetto, Visello) and two population varieties (Dańkowskie Diament, Kier) were included. The research showed that the content of anti-nutritive compounds in rye grains depended significantly on the genotype and weather conditions. Stress conditions during the rye growing season in 2011 and 2013 were the cause of higher synthesis of alkylresorcinols, soluble pentosans and trypsin inhibitors in rye grains. The content of alkylresorcinols and water-soluble pentosans also depended significantly on the intensity of the production technology. The higher content of these compounds was found in rye grains from intensive technology. The production technology had no significant impact on the activity of trypsin inhibitors.

For economic, environmental, and climatic reasons, soil cultivation methods without the use of a plough have became increasingly popular in recent decades. As research has shown, their impact on the growth and yield of crops is not always positive, especially when direct sowing is used. Recently,...

Cultivar, habitat conditions and agrotechnology have an influence on the yield and chemical composition of rye grain. The main anti-nutritional substances present in rye grain include alkylresorcinols, water-soluble pentosans and trypsin inhibitors. The aim of this study was to determine the variability in yield and the concentration of anti-nutritional compounds in the grain of selected winter rye cultivars in relation to nitrogen fertilisation levels and weather conditions. Field studies were conducted at the Experimental Station of IUNG-PIB in Osiny (Poland) in two growing seasons (2018/2019 and 2019/2020). The experiment was located on pseudo-polylic soil using the randomised sub-block method in three replications. The first factor of the experiment was the level of nitrogen fertilisation (0, 70 and 140 kg N∙ha−1) and the second was the population (Dańkowskie Skand, Piastowskie) and hybrid (KWS Vinetto, SU Performer) winter rye cultivars. The study showed that the yield of winter rye depended on the genotype and the level of nitrogen fertilisation. The hybrid cultivars yield ed 17.9% higher in relation to the population cultivars. The content of anti-nutritional compounds in rye grain depended significantly on genotype, level of nitrogen fertilisation and weather conditions. The reason for the higher synthesis of anti-nutrients in rye grain was the stressful weather conditions occurring in the 2019/2020 season. Nitrogen fertilisation influenced the content of alkylresorcinols, water-soluble pentosans and trypsin inhibitor activity in grain. The interaction of cultivar and fertilisation was also found to shape the content of the aforementioned anti-nutrients.

Grains of four naked oat varieties (Amant, Maczo, Polar and Siwek) and one hulled oat variety (Kozak) from three consecutive years (2018, 2019 and 2020), grown under three different nitrogen fertilization regimes (40, 60 and 80 kg of nitrogen per hectare) were malted and then mashed in the laboratory conditions for the first time; this was carried out to determine whether hulled and naked oat grains possess favourable properties as a raw material for the production of malt. Most of the analysed samples possess a favourable Kolbach index (39.06–46.82%), good extractivity (81.07–81.97%) and rather good saccharification time (13.33–26.67 min); however, some disadvantages of the produced malts could be pointed out. During the congress mashing, the filtration time of the worts produced from the hulled and naked oat malts was long (96.67–110 min) and the wort volume was not satisfactory (155–228.53 mL). Subsequent studies over oat malting and mashing need to be performed to maximize oat potential as the raw material for the production of the malt.
