SUMMARYNine experiments were conducted in the south-east of Ireland on three contrasting soils over a 3-year period (1988–90) to test the effect of six cultivars at four rates of nitrogen on the grain yield and quality (ex-farm) of spring-sown malting barley.Blenheim gave the greatest grain yield and lowest protein on average. Blenheim and Prisma had similar low protein values but Prisma gave significantly lower (P <0·05) mean grain yields than Blenheim at all three sites. Corniche gave significantly lower (P <0·05 to 0·01) grain yields than Blenheim in all nine experiments. Choice of cultivar had a considerable effect (<16%) on the yield and protein content of malting barley but season and soil type had a much larger effect (2–3 times greater).The application of increasing increments of fertilizer nitrogen generally increased grain protein and screenings significantly (P <0·05 to 0·01) in all nine experiments but it did not always give increased grain yields. The levels at which nitrogen gave significant grain yield increases depended on season and soil type. Season and soil type had a much larger effect on grain yield and quality than nitrogen rate.It was not possible to relate grain yield to specific climatic factors except on the light textured soil in 1990 when severe moisture stress in the early part of the growing season reduced grain yield by 32·5% compared with the previous 2-year average.

Malt Barley

Malt barley production requires a technology increasing nitrogen use efficiency, because of a high sensitivity of barley total grain yield and quality parameters to external growth factors. In the conducted study an effect of two P fertilizers on the background of N application on total and technological grain yields were studied. The highest total grain yield was harvested on plots fertilized with 60 kg N/ha, irrespective of the P fertilizer type. However, the technological grain yield showed a high year-to-year variability; the highest was recorded in 2001 on the plot fertilized with 60 kg N/ha and the P-PAPR fertilizer. The N and S concentrations and N:S ratios in immature grains at harvest were used to evaluate both yield types. Nitrogen concentration in the final total yield allowed making yields prognosis with the highest probability. The maximum yields of technological malt barley were attainable provided that total S concentration in immature grains at harvest was above 0.23% and the N:S ratio was narrower than 8.0.

Grain Yield And Quality

Cultivation of malting barley is particularly challenging as the requirements of growers, for high yield, and that of the brewing industry, seeking a specific quality criteria, must be met simultaneously. Furthermore, significant genotypic and environmental variations in grain yield and quality properties may occur. To investigate the relationships between grain yield and quality parameters of spring malting barley, a 2-year experiment was carried out in order to characterise the genotypic and year effects on grain yield, quality properties, and yield components of 23 high-yielding varieties of spring malting barley under optimal nitrogen (N) fertilisation. Compared to the grain quality properties of the grain protein content and the grain retention fraction of grain size >2.5 mm, less genotypic and environmental variation in grain yield was observed. Grain yield was closely related to spikes per m2, suggesting the importance of tiller formation and establishment as a decisive factor influencing malting barley yields. A major interactive effect of genotypes and year on grain size was observed. Regarding weather effects, the global radiation intensity during the post-anthesis phase was the major factor affecting the final grain size in this study. Grain protein content was primarily dependent on the year effect, suggesting that optimal N fertilisation levels must vary between years to ensure the correct protein content required for the needs of the brewing industry is met. Therefore, we recommend further development strategies addressing N fertilisation and soil N mineralisation to optimise the production of spring malting barley.

Background. Among spring cereals, oat is one of the main grain crops in Siberia. The aim of this study was to determine how the parameters of adaptability in oat cultivars are correlated with yield and basic indicators of grain quality.Material and methods. The studies were carried out from 2011 to 2019 in the southern forest steppe of Western Siberia. The content of protein, crude fat and starch in grain, and its hull content were measured according to B. V. Pleshkov and N. S. Berkutova. Mathematical processing was performed following the guidelines by B. A. Dospekhov, S. A. Eberhart and W. A. Russell.Results. There was a significant variation in grain yield and grain quality (CV > 20%) in oat cultivars due to a high contribution from the conditions of the year (26.7...80.9%) as well as a strong direct (r = 0,607...0.825) or strong reverse (r = –0.660...–0.994) conjugation with climatic factors. As the protein content in grain increased, starch, oil (r = 0.960...0.962) and hull content (r = 0.442) increased as well. Naked oat cultivars manifested higher grain quality (4.6% protein, 17.6% starch, and 2.2% crude fat) and reduced yield (–1.45 t/ha) compared with hulled oat cultivars.Conclusion. Increased plasticity (bi) and stability (σ2d) of oat cultivars contributed to higher yields (rbi = 0.943;rσ2d = 0.344) but reduced grain quality indicators (rbi = –0.697…–0.812;rσ2d = –0.270…–0.300). Hull content in plastic cultivars decreased (rbi = –0.201).

The effect of seedbed conditions at the time of sowing on the grain yield and quality ex-farm of spring-sown malting barley was examined in three experiments in the south-east of Ireland in 1993–95. Blenheim malting barley sown in good seedbed conditions gave significantly (P<0·05) greater yields (3·1–9·6% more) than the identically treated crop, sown several days earlier, in less suitable seedbed conditions in all three experiments, but there was no effect on grain nitrogen content or the amount of screenings. The better soil conditions gave significantly (P<0·05) better plant emergence, a greater number of fertile tillers and more grains per ear.
