The ecological characteristics and agro-ecological conditions in Hungary provide opportunities for quality wheat production. For the successful wheat production besides the favorable conditions; the proper use of expertise and appropriate cultivation techniques are not negligible. Successful cultivation affected by many factors. To some extent we can affect, influence and convert the abiotic factors. Today, a particularly topical issue is the question of nutrition and that the species’ genetic code can be validated using the appropriate quantity and quality fertilizer. Beyond determining the fertilizer requirements of the winter wheat it is important to align the nutrient to the plant’s nutrient uptake dynamics and to ensure its shared dispensing. In any case, it is important to note the use of autumnal base-fertilizer as complex fertilizer. Hereafter sharing the fertilizer during the growing season with the recommended adequate nitrogen dose.The first top dressing of winter wheat in early spring (the time of tillering) can be made, the second top dressing at the time of stem elongation, and the third top dressing at the end of the blooming can be justified. Determining the rate of fertilizer application depends on the habitat conditions and the specific nutrient needs of plants. In autumn the 1/3 of the planned amount of basic fertilizer should be dispensed (in case of N). During setting our experiment we used 3 doses (0 kg ha-1 N-1 active ingredient; 90 kg ha-1 N-1 active ingredients and 150 kg ha-1 N-1 active ingredient). Application dates beyond the autumn basic fertilization are the following: in one pass in early spring, divided in early spring and the time of run up, early spring and late flowering. In addition to nitrogen the replacement of sulfur gets a prominent role as a result of decreased atmospheric inputs. The proper sulfur supply mainly affects the quality parameters. It influences positively the wheat flour’s measure of value characteristics (gluten properties, volume of bread, dough rheology. In terms of nitrogen doses; the larger amounts (150 kg ha-1 N-1 drug), is the proposed distributed application, while in the case of lower nitrogen (90 kg ha-1 N-1 drug) in a single pass in the early spring can achieve better results. After using sulfur the quality values among the nutritional parameters that can be associated with gluten properties took up higher values than the samples not treated with sulfur.

Wheat is a vital crop in Georgia and in the world. Because of the increase in the rate of population growth, improving the grain yield is the way to meet food demand. Proper crop nutrition plays a vital role in maintaining the world’s food supply. Fertilizer is essential for accomplishing this.One of the most important means for increasing the wheat yield is fertilizer, especially, organic fertilizer. The present research was carried out to study the effects of different doses (150ml, 200ml and 300 ml on ha) of humic organic fertilizer “Ecorost” on yield of winter wheat cultivar “Tbilisuri 15”. The humic liquid fertilizer "Ecorost" is a peat-based organic-mineral fertilizer. The product is active and saturated due to the use of the latest technology and living bacteria found in peat. The field trials were conducted in 2017-2019 at the Experimental Site of Scientific Research Center of Agriculture in Dedopliskharo- arid region (Eastern Georgia).Liquid fertilizer was applied two times: in tillering stage in early spring and two weeks after - in stem elongation stage. Results indicated that the highest wheat grain yield (4t/ha) was achieved when the plants were fertilized with 300 ml on 1 ha ofEcorost. Applications of liquid fertilizer “Ecorost” increased grain yield of winter wheat by 16.2% in comparison with standard nitrogen fertilization. Thus, liquid fertilizer “Ecorost” had a significant effect on wheat grain yield compared to control standard nitrogen fertilizer.

AbstractNitrogen (N) application and irrigation to winter wheat may decrease leaf temperature and enhance photosynthesis: as a result, more photosynthates will be allocated to the grains, resulting in higher grain yields. To investigate this hypothesis, a 2-year field study was conducted with three levels of N fertilizer application (no fertilizer, N0; 240 kg N/ha, N1; 360 kg N/ha, N2) and two different water regimes (rainfed with no irrigation, R; irrigation at the over-wintering, stem elongation and grain filling stages, W). The results show that both N application and supplemental irrigation significantly increased grain yield with increases in both grain number/m2 and the 1000-grain weight, viz., WN2>WN1>WN0>RN2>RN1>RN0. In addition, application of N under both water regimes significantly increased flag leaf area, above-ground biomass and single stem productivity and decreased leaf temperature, which led to an increase in net photosynthesis rates and ribulose bisphosphate (RuBP) carboxylase activity. Moreover, analysis of the chlorophyll α fluorescence transient showed that N fertilizer application and supplemental irrigation significantly increased electron donor and acceptor performance of the photosystem II reaction centre.

Fall Application

Recommendations regarding the timing of herbicide application in winter wheat vary among production areas. The current increase in area of winter wheat production in Saskatchewan warrants an examination of herbicide recommendations for this non-traditional production area. Field research was conducted for 2 yr at several locations in Saskatchewan using 2,4-D, MCPA, dicamba, bromoxynil, chlorsulfuron, and clopyralid, applied in the late fall or early spring, to determine the effects of time and rate of application on winter wheat grain yield. Winter wheat (Triticum aestivum L. ’Norstar’) was tolerant to fall application of all herbicides at rates recommended for spring application. Grain yield was reduced in some cases when double the recommended spring rate of 2,4-D, MCPA, bromoxynil, and clopyralid was applied in the fall. Spring application of clopyralid resulted in significantly lower grain yield than fall application. All herbicides tested show potential for use in winter wheat production, although caution is warranted for spring application of clopyralid.Key words: Wheat (winter), 2,4-D, MCPA, dicamba, bromoxynil, chlorsulfuron

Field studies were conducted in 2014 and 2015 in Tennessee to examine pyroxasulfone dissipation under field conditions of winter wheat production. Three formulations were examined: (1) a single component active ingredient in an 85% dry flowable, (2) dry flowable formulation in combination of pyroxasulfone+flumioxazin, and (3) a liquid SC formulation of pyroxasulfone+carfentrazone. The liquid formulation is a suspo-emulsion. When averaged across the three studies, the DT 50 were 34.4, 30.2 and 29.9 d for pyroxasulfone plus carfentrazone, pyroxasulfone, and pyroxasulfone plus flumioxazin, respectively. These trends would indicate that formulation had little or no effect on pyroxasulfone dissipation in this experiment. Pyroxasulfone DT 50 in all studies ranged from a low of 15.4 d to a high of 53.3 d, and loss was more rapid under warm, moist conditions. These results indicate that pyroxasulfone would last long enough to provide residual weed control, but would not persist excessively to injure rotational crops.

Agriculture has traditionally an important role in Hungarian economy and rural development. About 75 % of Hungary’s total territoryis under agricultural land use. Because of ecological conditions and production traditions cereals (wheat, maize etc) have the greatestimportance in Hungarian crop production. In the 1980’s the country-average yields of wheat were about 5,0-5,5 t ha-1 („industrial-like”crop production-model). In the 1990’s the yields of wheat dropped to 4,0 t ha-1 because of low input-using and wide application of the issuesof environmental protection and sustainability. Winter wheat production for quality has a decisive role in certain regions of Hungary(eastern and middle-parts).The quality of wheat is complex and different. Three major growing factor groups determine the quality of winter wheat: genotype,agroecological conditions and agrotechnical factors. In wheat production for quality the selection of the variety is the most importantelement. Our long-term experiments proved that the quality traits of a variety means the highest (maximum) limit of quality which could notbe exceeded in fact. During the vegetation period of wheat the different ecological and agrotechnical factors could help or on the contrarycould demage the quality parameters of wheat.The agrotechnical factors determining the baking quality of wheat can be divided into two groups: the first group means the factors withdirect effects on quality (fertilization, irrigation, harvest); the second group contains the elements with indirect effects on quality (croprotation, tillage, planting, crop protection).Appropriate fertilization could help to manifest the maximum of quality parameters of a wheat genotype and could reduce the qualityfluctuationin unfavourable ecological and agrotechnical conditions.

In the years 2011–2014, winter wheat grain yield, qualitative and economic parameters were evaluated according to different fertiliser treatments: (1) control: unfertilised treatment; (2) farmyard manure (FYM) and (3) FYM + NPK (farmyard manure applied together with mineral NPK). The highest yields (8.10 t/ha) were recorded in the FYM + NPK treatment, while significantly lower yields (6.20 t/ha and 5.73 t/ha) were recorded in FYM and control treatments, respectively. Similarly, statistically significantly higher values of the quality parameters were found in the FYM + NPK treatment (13.55% of crude protein content and 43.56 mL of Zeleny’s sedimentation test), compared to control (10% and 22.44 mL, respectively). The modelling expert system (AGROTEKIS-Crop Technology and Economy) was used for the evaluation of economy. This software is based on technological methods of cultivation and norms of material input costs and costs of individual mechanised works. The economic benefits and profitability were evaluated for three different levels of grain market price. The highest gross profit per ha was recorded in the FYM + NPK treatment. According to the gross profit, the control treatment provided better results than the FYM treatment.
