The world in 21st century is facing the problem of growing energy consumption while the supply of fossil fuels is being reduced. This resulted in the development of research into the use of renewable energy sources and development of new technologies for energy production. In Polish conditions the development of agricultural biogas plants finds its legitimacy in the document developed by the Ministry titled "Trends in agricultural biogas plants in Poland in 2010-2020”. The purpose of this study was to investigate the influence of the weather conditions and the degree of nitrogen fertilisation on yield of reed canary grass (Phalaris Arundinacea L.) and to determine their susceptibility to anaerobic digestion, and usefulness of the production of biogas. Carried out experiments showed that increasing nitrogen fertilisation (from 40 to 120 kg N/ha) linearly increased canary grass green biomass yield from 32 to 46.3 t/ha. However, the highest biogas yield 126 m3/ha was obtained when 80 kg N/ha was applied.

Evaluation and Use of Genetic Resources in Spring Malting Barley Breeding in Lithuania During the period 2004-2006, grain yield stability and malt quality characteristics of 47 spring barley varieties and 55 promising breeding lines from the collection of spring barley genetic resources were investigated at the Lithuanian Institute of Agriculture (LIA). The growing conditions in 2004 were fairly normal compared with the long-term mean, and the years 2005 and 2006 were rather dry. The varieties and breeding lines tested showed from medium to high variation of grain > 2.5 mm yield (CV 11.5-34.3%) and medium variation of grain yield (CV 4.39-13.33%). However, high temperatures and drought in June of 2006 caused a low grain > 2.5 mm yield (by on average 55.0-67.8%). Promising breeding lines were characterised as having higher grain yield and extract output per ha compared with barley varieties. However, the data showed that grain grading 2.5 mm should be improved for the breeding lines. Using the software STABLE we estimated the stability of malting barley quality traits in relation to weather conditions during the crop year, genotype properties for varieties and breeding lines, as well as the interactions of variety and weather conditions. The selection of lines promising in terms of grain yield, > 2.5 mm grain yield and extract yield, was based on their ability to realise the genetic potential in various growing conditions. The highest score in integral assessment of grain yield, grain > 2.5 mm yield and extract yield was identified for the varieties Tocada', Sebastian', Scarlett' and breeding lines: 7939-1, 7661-1, and 8080-4. The varieties and breeding lines that exhibited high grain stability, high grain quality and other agronomic traits were utilised in further breeding programmes.

The estimation of Raushan variety of barley and the new Kamazhevsky variety, which was regionalized in Tatarstan in 2017, is given. The experiment revealed the influence of weather conditions and varieties during the years of research (2015-2017), on the formation of grain productivity, the content of total nitrogen in the aboveground mass of plants, the accumulation of protein in grain and gross harvest of protein per hectare. It is noted that the productivity for different years are different, the highest yields of grain of Raushan and Kamashevsky varieties were obtained in 2017 - 4.62 and 5.21 tons per hectare, respectively, when the hydrothermal coefficient was 1.3 units. In comparison with 2015 the productivity of Raushan variety was higher to 1.89 tons per hectare and to 1.69 tons per hectare in 2016. The same pattern was also found in Kamashevsky variety, 1.64 and 1.52 tons per hectare, respectively. The average productivity of Raushan variety for 3 years was 3.43 tons per hectare, less to 0.73 tons per hectare than Kamashevsky. The highest nitrogen content (close to the optimum 4.7-5.1%) in the aboveground mass was found in 2016 in plants of Raushan variety of 4.3%, Kamashevsky variety 4.0%, whereas in 2017 - 2.89% and 3.32%, respectively. The nitrogen content in dry years is higher in the aboveground mass of the Raushan variety, beginning with the tillering phase - 4.3%, Kamashevsky variety - 4.0%. It was revealed that the maximum content of protein in grain grade Kamashevsky accumulate in arid 2015-2016 years - 13.84%, more by 0.95% than the Raushan variety. In 2017 the protein content in the grain was formed at the same level Raushan 11.77%, Kamashevsky 11.07%. Evaluation of varieties on the gross harvest of protein per hectare, shows that the Kamashevsky variety forms on average 5.37 tons per hectare of protein over 3 years, more than Raushan grade by 1.08 tons per hectare.

NPK fertilizer briquettes (NPKBriq) and organically enhanced N fertilizer (OENF), as newly developed fertilizer products, are reported to increase maize (Zea mays L.) yield and N use efficiency, but their effects on maize grain composition are unknown. The objective of this study was to determine the effects of NPKBriq and OENF on the protein, oil, fiber, ash, and starch of maize grain. A field study was conducted at Jackson and Grand Junction, TN, during 2012 and 2013, with NPKBriq, OENF, ammonium sulfate ((NH4)2SO4) (+P and K), and urea (+P and K) as the main treatments and 0, 85, 128, and 170 kg N ha−1 as the sub treatments under a randomized complete block split plot design with four replicates. The fiber concentration was more responsive to the fertilizer source than the protein, oil, ash, and starch concentrations. OENF resulted in a higher fiber concentration than NPKBriq at 85 kg N ha−1 in 2013, averaged over the two sites. Both OENF and NPKBriq had nearly no significant effects on the concentrations of the quality attributes compared with ammonium sulfate and urea. In conclusion, the nutrient-balanced NPKBriq exerts the same or greater effects on maize grain quality relative to the commonly used nutrient management practices of urea (+P and K) and ammonium sulfate (+P and K) under normal weather conditions. OENF is an alternate N source to urea and ammonium sulfate for similar to higher maize grain quality.

The associations between Fusarium head blight (FHB), caused by Gibberella zeae, and deoxynivalenol (DON) accumulation in spring malting barley (Hordeum vulgare) and hourly weather conditions predictive of DON accumulation were examined using data from six growing seasons in the U.S. Northern Great Plains. Three commonly grown cultivars were planted throughout the region, and FHB disease and DON concentration were recorded. Nine predictor variables were calculated using hourly temperature and relative humidity during the 10 days preceding full head spike emergence. Simple logistic regression models were developed using these predictor variables based on a binary threshold for DON of 0.5 mg/kg. Four of the nine models had sensitivity greater than 80%, and specificity of these models ranged from 67 to 84% (n = 150). The most useful predictor was the joint effect of average hourly temperature and a weighted duration of uninterrupted hours (h) with relative humidity greater than or equal to 90%. The results of this study confirm that FHB incidence is significantly associated with DON accumulation in the grain and that weather conditions prior to full head emergence could be used to accurately predict the risk of economically significant DON accumulation for spring malting barley.

An, H. and Carew, R. 2015. Effect of climate change and use of improved varieties on barley and canola yield in Manitoba. Can. J. Plant Sci. 95: 127–139. A stochastic production function was estimated to investigate the effect of fertilizer inputs, changes in weather conditions and the use of improved varieties on barley and canola yields and its variability in Manitoba. Adoption of improved barley varieties did not have a significant effect on yield, while the adoption of herbicide-tolerant hybrid canola varieties was positively correlated with yield. An increasingly warmer climate in Manitoba is expected to have a slightly negative effect on mean barley yield and yield variance. In contrast, a warmer climate is expected to have a negligible effect on mean canola yield, but a positive effect on yield variability. Our results showed that a projected 50% increase in growing degree days would lead to a decrease of less than 1% in barley and canola yields.

Agronomic management and environment affect malting barley yield and quality. The objective of this study was to determine optimum agronomic practices (cultivar, fertilization, and seeding rate) for yield and quality of malting barley. A study was conducted during 2012–2014 in the region of Požarevac, southeastern Serbia, to evaluate the weather-dependent effect of seeding rate (S1=350, S2=450 and S3=550 seeds m–2) and nitrogen fertilization rate (N1=45, N2=75, N3=95 and N4=135 kg N ha–1) on the yield and quality of spring malting barley cultivars ('Novosadski 448', 'Novosadski 456', 'Dunavac' and 'Jadran'). Increasing seeding rate had a significantly negative effect on the quality, whereas the effect on yield was dependent upon weather during the growing season. Grain yield and grain protein content significantly increased with an increase in nitrogen rate up to 135 kg N ha–1. The optimum nitrogen rate for the average thousand-kernel weight and percentage of kernels ≥ 2.5 mm in all years was 75 kg N ha–1, and for test weight 105 kg N ha–1. Germinative energy depended on genotype and weather conditions, whereas seeding and nitrogen rates had a significant effect only during the first year. Results indicated that seeding rates above 350 seeds m–2 and nitrogen rates above 75 kg N ha–1 led to substantial grain quality deterioration in barley cultivars. © 2021 Friends Science Publishers
