It has been shown that pre-sowing treatment increases field germination by 5.5%, and the preservation of plants after overwintering increases by 4.3%. Gumiton strengthened the work of the assimilation apparatus of the flag leaf due to an increase in leaf area by 29.3-49.1% and extended the life of plants. As a part of a tank mixture (Tabu Super, 1.5 l / t + Tertia, 2.5 l t), the drug allowed to reduce the prevalence of the root rot disease to 2.45-1.05% in comparison with the control. The organomineral complex provided the formation of a larger and more leveled grain with a mass of 1000 grains of 47.0-47.5 g, 43.9 g in the control; the grain nature is more than 780 g / dm 3, 751.7 g / dm 3, in the control. The use of Gumiton (seeds + tillering + piping) against the background of N 96 P 96 K 96 provided a high yield increase by 37.8%. To reduce the expenses of foliar fertilization with nitrogen fertilizers, the Gumiton organic-mineral complex should be recommended, since it is an element of greening in intensive technologies of winter wheat cultivation.

Multivariate random-effects meta-analyses were conducted on 12 years of data from 14 U.S. states to determine the mean yield and test-weight responses of wheat to treatment with propiconazole, prothioconazole, tebuconazole, metconazole, and prothioconazole+tebuconazole. All fungicides led to a significant increase in mean yield and test weight relative to the check (D; P < 0.001). Metconazole resulted in the highest overall yield increase, with a D of 450 kg/ha, followed by prothioconazole+tebuconazole (444.5 kg/ha), prothioconazole (419.1 kg/ha), tebuconazole (272.6 kg/ha), and propiconazole (199.6 kg/ha). Metconazole, prothioconazole+tebuconazole, and prothioconazole also resulted in the highest increases in test weight, with D values of 17.4 to 19.4 kg/m3, respectively. On a relative scale, the best three fungicides resulted in an overall 13.8 to 15.0% increase in yield but only a 2.5 to 2.8% increase in test weight. Except for prothioconazole+tebuconazole, wheat type significantly affected the yield response to treatment; depending on the fungicide, D was 110.0 to 163.7 kg/ha higher in spring than in soft-red winter wheat. Fusarium head blight (FHB) disease index (field or plot-level severity) in the untreated check plots, a measure of the risk of disease development in a study, had a significant effect on the yield response to treatment, in that D increased with increasing FHB index. The probability was estimated that fungicide treatment in a randomly selected study will result in a positive yield increase (p+) and increases of at least 250 and 500 kg/ha (p250 and p500, respectively). For the three most effective fungicide treatments (metconazole, prothioconazole+tebuconazole, and prothioconazole) at the higher selected FHB index, p+ was very large (e.g., ≥0.99 for both wheat types) but p500 was considerably lower (e.g., 0.78 to 0.92 for spring and 0.54 to 0.68 for soft-red winter wheat); at the lower FHB index, p500 for the same three fungicides was 0.34 to 0.36 for spring and only 0.09 to 0.23 for soft-red winter wheat.

AbstractThe paper presents analysis of the impact of irrigation dose on the winter wheat Bystra yield, which is recommended for cultivation in Poland. It is a low-growing high-yield wheat cultivar. A reel sprinkler equipped with a computer for control of parameters of its operation, which was supplied with pond water was used for irrigation. Test were carried out on five fields, where four irrigation doses were used: 15, 20, 25, 30 mm. A change of weather during research in May and June caused the need to irrigate a field four times. During research, the size of the irrigation dose was measured with rain gauges on each of the investigated fields in five measurement points. One of the fields was a control field, which was not irrigated. The investigated wheat was characterized during harvesting. Research proved that the size of the irrigation dose influences the wheat yield. The grain yield between a control field and a field with the highest irrigation dose increased by twofold. Moreover, analysis of costs incurred during sprinkling were analysed.

AbstractQuantifying reasonable crop yield gaps and determining potential regions for yield improvement can facilitate regional plant structure adjustment and promote crop production. The current study attempted to evaluate the yield gap in a region at multi-scales through model simulation and farmer investigation. Taking the winter wheat yield gap in the Huang-Huai-Hai farming region (HFR) for the case study, 241 farmers’ fields in four typical high-yield demonstration areas were surveyed to determine the yield limitation index and attainable yield. In addition, the theoretical and realizable yield gap of winter wheat in 386 counties of the HFR was assessed. Results showed that the average field yield of the demonstration plots was 8282 kg/ha, accounting for 0.72 of the potential yield, which represented the highest production in the region. The HFR consists of seven sub-regions designated 2.1–2.7: the largest attainable yield gap existed in the 2.6 sub-region, in the southwest of the HFR, while the smallest was in the 2.2 sub-region, in the northwest of the HFR. With a high irrigated area rate, the yield gap in the 2.2 sub-region could hardly be reduced by increasing irrigation, while a lack of irrigation remained an important limiting factor for narrowing the yield gap in 2.3 sub-region, in the middle of the HFR. Therefore, a multi-scale yield gap evaluation framework integrated with typical field survey and crop model analysis could provide valuable information for narrowing the yield gap.

Winter wheat productivity and grain quality is largely dependent on the availability of mineral elements of plants throughout the growing season. [2] Early spring fertilization with nitrogen fertilizers contributes to more rapid growth of the root system, further tillering, strengthening of ear shoots development and highest yield increase. Application of fertilizers, containing micronutrients (Akvarin 5), having a complex effect on plants, is perspective in high quality grain production. In this paper, we studied the effect of nitrogen nutrition and trace elements on grain productivity and quality, perspective and zoned species in the Republic of Tatarstan. Spring introduction of nitrogen in the form of ammonium nitrate leads to an increase the density of productive plant stand to 10.0%, crop yield to 20%. Treating the plant by Akvarin5 preparation in tillering period, it increases the density of plant stand of winter wheat on average 2.89%, productivity to 4.3% or 0.21 tons per hectare, compared to one with a nitrogen fertilizing. Akvarin 5 preparation leads to weight rising of 1000 grains more significant at making it in earing - flowering phase, than in the phase of tillering. It also increases the weight of the grain and gluten content. A greater influence on the nature of grain has a nitrogen fertilizer, than treatment by Akvarin 5.

AbstractSeasonal abundance of Sitobion avenae (F.) and Rhopalosiphum padi (L.) was monitored in Nova Scotia winter wheat plots. Rhopalosiphum padi was the more common aphid species during "heading out." Winter wheat cultivars differed in their resistance to R. padi development; the highest reproductive rate was on ’Absolvent.’ The effect of chemicals used in intensive cereal management on R. padi and Coccinella septempunctata (L.) was assessed. Dimethoate and carbaryl caused similar high mortality to both insects, but pirimicarb was more toxic to the aphid than to its predator. Over a 2-year period, field plots that received regular pirimicarb treatments for selective aphid control early in the growing season showed a 9% increase in wheat yield, compared with the checks and plots that received carbaryl. Wheat yield increased 18% when pirimicarb was used later in the season; when applied in both periods, pirimicarb gave a total yield increase of nearly 30%. Late applications of carbaryl alone, or in combination with pirimicarb, increased yields by only 9% over the controls. Half of the yield increase (18% vs. 9%) with late season control by pirimicarb was lost with the addition of carbaryl, which minimized the C. septempunctata population for nonselective insect control. Rhopalosiphum padi numbers from June 20 to July 15 had the greatest impact on yield in these plots, and natural control agents including C. septempunctata accounted for a 9% increase in yield.

N Fertility

In areas with favourable growing conditions, high seeding rates (SRs), narrow row spacings (RSs) and nitrogen fertilization (N) are required before high yield potentials of winter wheat (Triticum aestivum L.) are realized. Changes in these variables produce changes in crop-canopy microclimate that may influence the development of foliar pathogens. This study examined the relative differences in crop-canopy microclimates due to different RS and SR combinations and determined the effect of SR, RS and N fertility on septoria (Septoria nodorum Berk. and Septoria tritici Rob. ex Desm.) development on normal height and semi-dwarf cultivars grown under no-till in the Parkland region of Saskatchewan. The daily mean value for solar radiation penetrating to the base of the crop canopy was 1100 μmol m−2 s−1 for 36-cm RS. This was 30% higher than the 845 μmol m−2 s−1 observed for 9-cm RS. The increased light interception by the canopy was associated with higher dry matter production and grain yield. During peak periods, wind speed was 56% higher within the 36-cm RS canopy than within the 9-cm RS canopy. Increased duration of leaf wetness was associated with 9-cm RS and 140-kg-ha−1 SR treatment. Cooler air temperature and higher RH within the canopy occurred for the 9-cm RS – 140-kg-ha−1 SR treatment. Differences in air temperature and RH between the 9-cm RS – 140-kg-ha−1 SR and the 36-cm RS – 35-kg-ha−1 SR treatments were smaller at night and greater during the day. The maximum differences occurred at mid-morning and mid-afternoon, when the 9-cm RS – 140-kg-ha−1 SR canopy was 1.5 °C cooler and had a 4.5% higher RH than the 36-cm RS – 35-kg-ha−1 SR canopy. Septoria severity increased when SR increased from 35 kg ha−1 to 140 kg ha−1. Septoria severity was not influenced by RS. Septoria severity was greater on the flag leaf of the semi-dwarf cultivar Norwin than on the tall cultivar Norstar. Increased N fertility reduced septoria severity in one trial. These observations demonstrated that, in addition to the influence on yield potential, high SR and narrow RS produce a canopy microclimate that is favourable for the development of septoria.

This is the first time in conditions of Semisavanna of Ukraine when mutual effect of winter wheat precursors and three complex growth-regulating preparations on the growth, development and yield of winter wheat grain has been studied. It has been determined that Antistress, Mars-EL and four amino acid complex preparations can be used for winter wheat growing technology with the aim to increase its yield both during the naked fallow sowing, and after a grain precur- © Позняк В. В., 2019 sor. Greater effect is provided by preparations at winter wheat re-sowing - the yield increase made 0.32-0.81 t/ha. The less significant but stable increase in yield of 0.27-0.59 t/ha is provided by complex growth-regulating preparations during sowing wheat over wheat. Use of the studied complex preparations with a wide range of action throughout the growing season had a positive effect on indicators characterizing growth, development and formation of winter wheat yield. The most effective was the joint use of Antistress and Mars-EL preparations (0.5-0.71 t/ha increase) and all the three drugs together (Antistress + Mars-EL + amino acid complex) when additional 0.59-0.81 t/ha of grain was obtained. Thus, our research has shown that use of new promising growth-regulating agents for winter wheat growing technology makes it possible to implement its genetic potential and increase yield more efficiently, which undoubtedly is of a great importance for agricultural farms specializing in production of this crop.

In Poland winter wheat is grown on the area of 1.600.000 ha. Most of the plant protection treatments are being done without thorough analysis of real threats from pests and diseases. The aim of the research is to develop the optimal program of wheat protection against pests and diseases based on integration of various methods of plant protection. Two programs: conventional and integrated were compared. In integrated program the eventual needs and terms of treatments were estimated on the basis of detailed observations of plant infection, pest appearance, their natural enemies and thorough analysis of weather conditions and forecasts. The role of disease resistant wheat varietes and nitrogen fertilizers was also analysed. The research took into account beneficial entomofauna and its influence on pest numbers as well as influence of chemicals used in agriculture on their species. As the result the selective pesticides, safe to beneficial organisms, were selected. The quantity and quality of winter wheat yield was analysed, including protein and gluten contents. The economic effectiveness of various programs of wheat protection against pests and diseases was assessed. The results of research are important both in practical and scientific sense.
