“…Only in 2008 the application of the PRP SOL was proved to result in a significant decrease in the compaction of the soil layer at a depth of 10 cm, whereas all the other variations, regardless of the research year and measurement depth were statistically insignificant. These significant differences in 2008 may be due to wet weather conditions in April which also Janušauskaitė et al (2013) pointed out in their investigation. The authors proved that varietal and stand density of spring barley effect on photosynthetic rate, transpiration rate, and instantaneous water use efficiency was more strongly expressed in wet conditions (2008) mentioning that in 2008 and 2010 at a depth of 20 cm the decreasing compaction tendency was proved, whereas in 2009 this tendency was observed at a depth of 30 cm.…”

Summary. The aim of the application of a PRP SOL complex of MIP bioactive compounds is to improve the soil characteristics by unblocking the potential of the nutrients in the soil and making them available to plants. This fertilizer is used for soil fertilization rather than crop nutrition. The research focused on evaluation of the yield of spring barley after the application of the PRP SOL technology in the fields of the Research and Education Center Gorzyń, at the Experimental Station in Złotniki, in 2007 to 2011. The purpose of the research was to compare the effects of spring barley fertilization technology by applying a complex of MIP bioactive compounds in the form of a PRP SOL fertilizer with the standard technology applying phospho-potassium fertilization. The five years of the research led to the conclusion that the traditional fertilization of spring barley plantations with phosphorus and potassium can be replaced with the technology applying the MIP complex without grain yield losses. However, the yield was not stable between years. In one of the five research years (2007) there was a significant increase (by 3.7 dt•ha -1 ), and in another (2010) a significant decrease (by 3.2 dt•ha -1 ) as a result of fertilizer use. The PRP SOL fertilizer may be particularly useful for malting barley due to the favourable increase in the share of lush grain fractions (larger than 2.5 mm) and simultaneous decrease in the share of smaller grains and due to the fact that the weight of 1 hl tends to decrease whereas the thousand grain weight tends to increase.

“…Cereal grain yield is a complex of multi component character and is greatly influenced by various environmental conditions. Grain chemical composition (including amino acids) of different cereal varieties depends on various factors such as grain size, sowing time (Kong et al, 2014) genotype, climate conditions (Janušauskaitė et al, 2013), environment (Akçura et al, 2011), fertilisation, soil conditions (Manès et al, 2012). These parameters can affect chemical characteristics of cereal grains, including their energy content, crude protein, fibre fractions or minerals (Rodehutscord et al, 2016).…”

The objective of this research was to evaluate the chemical composition of grain of 20 winter wheat, rye and triticale varieties grown in Lithuania. The grain of the tested varieties was analysed for crude protein, crude fat, crude ash, crude fibre, and amino acids. The Pearson's correlation coefficient between the components of grain chemical composition (except amino acids) was calculated. The highest concentration of crude protein was determined for the variety 'SW Talentro' (triticale) and the lowest for the rye variety 'Palazzo' (P < 0.05). Among the wheat varieties tested, the 'Mariboss' contained the highest concentration of crude fat (1.56% dry matter) and crude fibre (2.19% dry matter) (P < 0.05). Among the rye varieties tested, the highest and dominant mean content of neutral detergent fibre was determined for the variety 'Matador' (20.59% dry matter) (P < 0.05). The grain of wheat varieties had a high content of acid detergent fibre ('Rigi') and acid detergent lignin ('Mariboss') (P < 0.05). Furthermore, a very strong correlation was determined between individual fibre fractions of grain, that is between hemicellulose and neutral detergent fibre content (r = 0.99) and between acid detergent fibre and cellulose (r = 0.93). A negative correlation was determined between the crude protein and nitrogen-free extract (r = −0.83). The study revealed that the wheat variety 'Zentos', the rye variety 'Dankowskie Amber' and the tirticale variety 'SW Talentro' accumulated a higher amount of amino acids in comparison with the other cereal varieties tested. The results of the study showed that the chemical composition (crude protein, essential amino acids, nitrogenfree extract, neutral detergent fibre) of grain of the triticale varieties was more similar to that of wheat varieties compared with rye varieties.

“…The amount of photosynthetic pigments in the leaves varies depending on the plant species, variety and environmental conditions (Daughtry et al, 2000). It was found that the unequal change in photosynthetic parameters of different winter wheat varieties was evident in the presence of drought and depended on plant development (Janušauskaitė et al, 2013;Sharifi and Mohammadkhani, 2016;Wang et al, 2018). In the spring barley crops, the highest photosynthetic productivity was defined in the stages of heading-anthesis -milk maturity, that is, during intensive growth accumulation of dry matter mass.…”

Six winter wheat varieties were studied in the experiment: 'Skagen' (control), 'Julius', 'Edvins', 'Artist', 'Aron' and 'Evina', which were sown on September 15. Preceding cropwinter rape. Seed rate -4.5 million ha -1 . The aspects of the dynamics of photosynthesis pigments in winter wheat leaves depending on variety is analysed in the article. Physiological activity of the plant, the growth and development are the most important moments decisive the accumulation of these pigments in the plant. Thus, the general condition of the plant might be described by the composition and content of photosynthesis pigments chlorophyll a, b and carotenoids. Spectrophotometric Wettstein method and "Genesys" 6 spectrophotometer were used for determination of the content of photosynthesis pigments (chlorophyll a, b and carotenoids) in green leaf mass in 96 % ethyl alcohol extract. The accumulated amounts of photosynthetic pigments (chlorophylls a, b and carotenoids) in different varieties of winter wheat leaves differed. Winter wheat variety 'Aron' accumulated the highest contents of photosynthetic pigments during the tillering and stem elongation stages, meanwhile during the headinganthesis and early milky maturity stages winter wheat varieties 'Artist' and 'Skagen' demonstrated the best results. The LAI of different varieties of winter wheat differed in the field experiment. Significantly higher LAI was defined for winter wheat variety Artist (0.9) after the resumption of vegetation (BBCH 24-27) and for 'Skagen' (4.0) at the end of vegetation . The highest LAI of winter wheat is determined during the heading -anthesis stage (varieties 'Aron', 'Edvins', 'Skagen'). During the growing season, the lowest LAI was observed for winter wheat variety 'Evina'.
