1000 Grain Weight

Since 1995 the Finnish Agri-Environmental Program has set limits for nitrogen (N) and phosphorus (P) fertiliser application rates in agriculture. The decrease in N and P fertiliser recommendations, and especially the decrase in N and P amounts applied in practice, has raised the question of whether N and P application rates are too low to produce high quality yields. The test weight, 1000 grain weight and protein concentrations measured in 1990–2005 by the Cereal Inspection Unit of the Finnish Food Safety Authority were analysed against soil type, location and NP fertiliser data. The purpose of this study was to document and statistically analyse changes in fertiliser use, important quality factors and the connection between fertiliser use and grain quality of spring barley (Hordeum vulgare L.), oats (Avena sativa L.), winter rye (Secale cereale L.) as well as spring and winter wheat (Triticum aestivum L.). Applications of N and P fertiliser, test weight and 1000 grain weight have decreased in Finland since 1990-1994. Protein content began to decrease in 1995–1999, but then increased in 2000–2005. The statistical analysis showed that reduced N application rates are associated with lower test weight, 1000 grain weight and grain protein concentration. In addition, low P application rates were associated with reduced 1000 grain weight and protein concentration in some instances, although protein concentration also increased in winter wheat grain. The magnitude of grain quality reduction was not solely explicable through N and P application rates. During the observation period many other factors changed in Finnish cereal production and, for example, the decrease in cereal prices, increase of reduced tillage and low investments in drainage and liming could have been associated with decreased grain quality.;

Forty-three mutant lines selected on the base of their high grain yield along with parent varieties Kuber, Zagorets, Asparuh, and Imeon were grown in field trials at the Institute of Agriculture – Karnobat in three consecutive years. Eight physical and chemical characteristics of grain related to the grain quality of malting barley were measured. There was considerable variation among barley mutant lines for all studied traits. Mutant lines with higher extract content, grain uniformity, 1000 grain weight, and lower protein content in grain compared to parent varieties were found. The correlations among traits showed that improvement of extract content of mutant lines was associated with increased grain uniformity, starch content, grain size, and 1000 grain weight and reduced protein content. The results from cluster analysis indicated that mutants originated from the same parent were grouped into different clusters. Therefore, the sodium azide treatment effectively induced diverse types of changes in the grain characteristics.

The range of variability (min maх) and variability of the main indicators of the technological qualities of grain different fractions of brewing barley varieties Bios 1 (selected in the Podmoskovie Science and Production Association) and hulled oats Argamak (selected in the N.V. Rudnitsky North-East agricultural research institute) and their (quality indicators) dependencies between themselves and the yield value is established. To the maximum extent (at largest coefficient of variation - V, %), the fractionation of brewing barley grain and hulled oats varies the 1000-grain weight and the protein content, the minimum is the test weight of both grain crops, extractivity of barley and hull of oats. A wide variation of the mass of 1000-grain weight and the protein content of the grain during fractionation makes it possible to significantly regulate them in the desired direction compared to such indicators as test weight, extractivity and hull of oats. The relationships between the main indicators of the technological qualities of brewing barley grain and hulled oats when fractionated on standard sieves with oblong holes are presented and discussed. A significant negative relationship was found between the extractivity and the protein content in the grain of different fractions of brewing barley. However, both of the studied cultures did not reveal any statistically significant dependencies of the test weight of the grain on the protein content in the grain of different fractions. The dependencies of the content of extractivity in the barley grain, the protein content in the grain and test weight of both the studied cultures and of 1000-grain weight have a complex non-linear character. It is shown that in most cases the dependencies between the main indicators of the technological qualities of barley and oats grains are most accurately (at largest R2) described by second-order equations with clearly defined extremum points that are within the experimental data obtained. Regardless of the folding hydrothermal conditions of the growing season, between the protein content in the grain of different fractions of brewing barley and hulled oats and their (fractions) yield, no statistically significant dependencies were found.

Abstract. The aim of this study was to assess the variation in grain quality traits among mutant lines of winter feed barley. Nine mutant lines derived from the advanced breeding line Kt3029 and 10 mutant lines derived from variety GA-Luttrell along with their parent forms were evaluated. The study was conducted at the Institute of Agriculture – Karnobat during the period 2015-2017. Test weight, 1000-grain weight, the content of protein, starch, lysine, fat, ash, and fibre were determined. Significant differences between the mutant lines and the parent forms for the studied traits were observed. Significantly higher protein content compared to parent was found in the grain of mutant lines 22/1-5, 22/2-10 and 22/1-12 from line Kt3029 and 26/1-1, 26/1-3 and 26/2-11 from variety GA-Luttrell. The grain of mutant line 26/2-12 had the best combination of protein and starch. Mutant lines 22/1-11 and 22/1-12 from Kt3029 and 26/1-1, 26/2-1 and 26/2-12 from variety GA-Luttrell showed a good combination between protein content and 1000-grain weight. Those mutant lines can be included in the breeding program for the development of varieties with improved feed quality.

SUMMARYVarietal and environmental factors which influence test weight were investigated in a field trial with ten varieties of winter wheat and two rates of nitrogen fertilizer. Varietal differences in test weight were correlated positively with the protein content of the grain and inversely with grain yield but they were not related to 1000-grain weight or to flour yield. Variation in test weight associated with varietal and environmental effects in protein content was due to differences in the density of the grain, as measured by displacement of xylene. Separation into density grades within a sample by a flotation method showed a similar relationship with protein content. There were also varietal differences in packing efficiency of the grain. In the case of Maris Huntsman a poor packing efficiency was considered to stem from morphological features of the floret and developing grain which lead to characteristic transverse folds in the ventral surface of the mature grain. For wheat grown in the United Kingdom, test weight may provide a useful guide to flour yield for samples of one variety but it is likely to be misleading for comparisons between varieties.

The article investigates the influence of the application of different systems of basic tillage on the quality of winter wheat grain in short crop rotations of the Southern Steppe of Ukraine. It is established that the grain quality of winter wheat in the Southern Steppe of Ukraine is mainly determined by the genetic characteristics of the variety, but also largely depends on the conditions and technologies of cultivation. In winter wheat grain, which is used for food purposes, reserve proteins are important, which in winter wheat determine the baking properties of flour. In drought conditions, when the yield of winter wheat decreases, the protein content in its grain tends to increase. In wet years, on the contrary, there is a reverse pattern. According to experimental studies, wheat varieties have a negative correlation between grain protein content and yield. It is established that during 2016–2020 research shows almost the same pattern of action of different predecessors and systems of basic tillage on the formation of grain quality of winter wheat in arid conditions. It was found that, on average, according to all variants of research, only with the use of the system of tillage-free tillage received grain of winter wheat with a protein content of 12,5%, which met the requirements of the 2nd class. It is recorded that on average over five years of research on all tillage systems, grain of winter wheat with gluten content was obtained, the quality of which corresponded to the 3rd class. Different tillage systems caused a slight impact on the gluten content, which ranged from 20,6% to 21,1%. It is determined that the precursors have a certain effect on the protein content in the grain of winter wheat. The analysis of qualitative indicators showed that on average in five years of research, when growing winter wheat after a pair of black and a pair of green wheat with winter vetch, grain was formed, which in terms of protein content corresponded to the 2nd quality class. More protein was accumulated in winter wheat grain after a pair of black, which was 12,9%. After peas for grain, as well as a pair of green with a mixture of white mustard and peas, received a grain of winter wheat, which was the 3rd quality class. It was found that on average in five years of research, all variants of winter wheat were grown with gluten content, which met the requirements of the 3rd class. Black vapor and green vapor with winter veneer caused the accumulation of gluten at almost the same level with a small increase in the version with winter vetch up to 21,8%. The lowest level of gluten was obtained in the grain of winter wheat after peas per grain, which was 19,7%. In all variants of the experiment, sidereal steam with winter tillage and the use of tillage-free tillage had the best effect on the growth of winter wheat grain quality indicators. The grain of winter wheat was mainly formed in terms of quality, which allows it to be used for food purposes – mainly in the flour-milling and baking industries, as well as for export. It is established that it is important to further study the quality of winter wheat grain and other cereals in short crop rotations of the arid Southern Steppe of Ukraine, especially in climate change.

Abstract Because phosphorus (P) is one of the most limiting nutrients in agricultural systems, P fertilisation is essential to feed the world. However, declining P reserves demand far more effective use of this crucial resource. Here, we use meta-analysis to synthesize yield responses to P fertilisation in grasslands, the most common type of agricultural land, to identify under which conditions P fertilisation is most effective. Yield responses to P fertilisation were 40–100% higher in (a) tropical vs temperate regions; (b) grass/legume mixtures vs grass monocultures; and (c) soil pH of 5–6 vs other pHs. The agronomic efficiency of P fertilisation decreased for greater P application rates. Moreover, soils with low P availability reacted disproportionately strong to fertilisation. Hence, low fertiliser application rates to P-deficient soils result in stronger absolute yield benefits than high rates applied to soils with a higher P status. Overall, our results suggest that optimising P fertiliser use is key to sustainable intensification of agricultural systems.

Winter Wheat Varieties

The studies were carried out in laboratory conditions on the basis of the Agrotechnological Institute of Northern Trans-Ural State Agricultural University. The studies include 5 varieties of winter wheat grown in 2009-2011 in three agroclimatic zones of Tyumen Region: sub-regional (Nizhnetavdinsky state crop testing site), northern forest steppe (Yalutorovsky state crop testing site), southern forest steppe (Berduzhsky state crop testing site). Bashkirskaya variety – 10 (45 g) demonstrated the highest potential in the formation of a 1000 grain weight. The same variety has the highest range of variability (11.7 g) and the variability coefficient (10.9%) indicates average variability. Other varieties showed minor variability of characteristic (V = 8.7-9.9%). Winter wheat varieties varied in terms of average hardness, at the same time the level of values of all varieties (66-77%) corresponded to the standards of high classes according to GOST. Novosibirskayaaya 32 (61-93%) and Bashkirskaya 10 (60-86%) varieties were the most stable in forming the required value of characteristic. The average gluten content in a grain of winter wheat varieties was corresponded to the standards of the third class according to GOST. Novosibirskaya 32 variety (V = 8.5%) had minor variability of the characteristic, while other varieties demonstrated the average variability. A significant proportion of the effect of the “variety” factor on the variability of such features as a 1000 grain weight (56.5%), grain-unit (50.5%) and hardness (45.1%) was established. The amount of gluten depended more on the growing environment (35.5%) and interaction of factors (39.3%). The quality of gluten was much influenced by the growing environment (52.2%).

A field experiment was conducted during kharif season of 2019 at Agronomy Main Research Farm, Odisha University of Agriculture and Technology, Bhubaneswar to study the effect of establishment methods and nutrient management on biochemical attributes, grain quality, yield parameters and yield of rice. The experiment comprised of two rice establishment methods, viz. direct seeded (DSR) and transplanted (TPR) and three nutrient management practices, viz. inorganic (soil test based fertilizer recommendation (STBFR), organic (1/3rd N through green manuring + 1/3rd N through neem oil cake + 1/3rd N through vermicompost) and integrated nutrient management (50% through STBFR + 50% through green manuring) laid out in a randomised block design with three replications. The results indicated that the concentration of chlorophyll was maximum at vegetative and gradually decreased up to maturity stage. TPR recorded comparatively higher total chlorophyll content (2.91mg g-1), grain C (40.58%), H (6.98%), S (0.18%), C/N (36.54), panicles hill-1 (6.78), panicle weight hill-1 (27.05 g), 1000 grain weight (27.86 g), number of filled grains panicle-1 (176.60) with 18.3 % yield advantage over DSR. Among nutrient management, INM recorded higher S (0.17%), carbohydrate (17.82%), panicle numbers hill-1 (8.5), panicle weight hill-1 (30.19 g), 1000 grain weight (28.13 g), number of filled grains panicle-1 (187.89), grain yield (4.36 t ha-1) with harvest index (39.67%), where as maximum N (1.48%), C (41.58%), H (7.07%), S(0.18%), C/H (5.87) was obtained in inorganic with grain yield (3.78 t ha-1). Organic produced the highest chlorophyll total (2.72 mg g-1), C/N (37.89) and harvest index (36.72%) with minimum grain yield (3.74 t ha-1). Hence, organic in conjunction with chemical ferilisers under TPR not only enhances the growth and yield but also improvement of biochemical attributes and grain quality of rice in coastal Odisha.
