Wheat production is significant branch of Hungarian crop production (with about 1 million hectares of sowing area). Weather anomalies resulted by climate change have increased the importance of biological basis in wheat production. Yield quality and quantity parameters of three wheat genotypes sown on chernozem soil type after maize pre-crop were studied in a long-term field experiment. Yield amount of the studied genotypes varied between 2894 and 8074 kg ha-1 in 2017 and between 5795 and 9547 kg ha-1 in 2018 depending on the applied treatments. Based on our results it can be stated that in both studied crop years the highest yield increment was realized by the application of the nutrient supply level of N30+PK. As the result of the application of the optimum mineral fertilizer level – in contrast to the control – resulted in significant yield increment in both crop years. The results of the long-term field experiment prove that water utilization of the studied wheat varieties / hybrids was improved by the application of the optimal nutrient supply. Furthermore, the water utilization of the latest genotypes was more favorable by both the control and the optimum nutrient supply level treatments. Analyzing the quality parameters of winter wheat using the NIR method it has been stated that the quality results of the well-known genotype (GK Öthalom) were better than those of the new genotypes. A negative correlation between winter wheat quality and quantity parameters has also been confirmed. As the result of the mineral fertilizer application protein and gluten content of winter wheat increased to a significant extent.

Wheat production is a determining branch within Hungarian crop production (near 1 million hectares). Weather anomalies caused by climatic change confirmed the importance of biological basis (variety, hybrid) in wheat production. The adapting ability and reaction of different wheat genotypes towards nutrient supply were studied in a long-term field experiment on chernozem soil type in case of different pre-crops (sweet corn, sunflower and maize). According to the experimental results of the vegetation 2017/2018 the most highest yield amount of the variety Ingenio sown after the pre-crop sunflower ranged between 2710 kg ha-1 and 8710 kg ha-1, while the hybrid (Hyland) in case of the pre-crop sweet maize between 6556 kg ha-1 and 9270 kg ha-1 depending on the applied nutrient supply level. The studied genotypes showed the highest quality (protein, gluten) in case of the pre-crop sweet maize. In the cropyear of 2017/2018, the protein content of Ingenio ranged between 12.2-14.8%, while the Hyland in case of the pre-crops sweet corn between 9.9-13.9%. The gluten content of the Ingenio genotype changed between 24.9-32.5%, in the case of Hyland ranged between 16.9-27.3% in the studied cropyear.

The aim of this work was to evaluate the changes of different sulphur forms (soluble, adsorbed) in chernozem soil in a long-term field experiment supplied with increasing doses of NPK fertilizers for a long time. In addition, other objective of this study included the examination of the applicability of recommended extractants of the different sulphate fraction in Hungarian soils. A long-term field experiment was established at the Research Station of Látókép of the University of Debrecen in 1984. In addition to control, two levels of NPK fertilizer doses have been used with irrigated and non-irrigated variants. Winter wheat and corn were cropped in a crop rotation on plots. Soil samples were collected in three different development stages of winter wheat, at the stage of stem elongation (April), flowering (May) and ripening (June of 2018) from the topsoil (0–20 cm) of experiment plots. Water-soluble inorganic sulphate was extracted with 0.01M CaCl2 solutions. The soluble plus adsorbed sulphate was extracted with 0.016M KH2PO4 solution. Sulphate was measured by turbidimetric method. 0.01M CaCl2-SO42— ranged between 0.293–1.896 mg kg-1 and the 0.016 M KH2PO4-SO42- varied between 5.087–10.261 mg kg-1. The values of KH2PO4 SO42- was higher than that of CaCl2-SO42-, because KH2PO4 extracted the adsorbed and soluble fractions of sulphate, while CaCl2 extracted the soluble sulphate fraction. The amount of absorbed sulphate was calculated by the differences of KH2PO4- SO4 and CaCl2-SO4. The KH2PO4 characterizes mainly the adsorbed sulphate fraction much more than the water-soluble fraction. KCl is the most widely used extractant for the determination of plant available sulphate content of soil in Hungary; therefore, KCl-SO42- fraction also was determined. The KCl-SO42- ranged between 0.328–2.152 mg kg-1. The CaCl2-SO42- and KCl-SO42- fractions were compared and based on Pearson's linear correlation, moderate correlation was established (r=0.511) between them. In all three extractant (0.01M CaCl2, 1M KCl, 0.016 M KH2PO4) higher sulphate fractions were measured in the fertilized plots where superphosphate had been supplied for ages until 2010. The arylsulphatase activity of soil also was determined and ranged between 9.284 and 26.860 µg p-nitrophenol g-1 h-1. The lowest value was observed in the treatment with highest NPK2 dose, both in irrigated and non-irrigated areas.

The technology quality parameters of winter wheat were analysed on the results of a variety and cropping site experiment and a variety and mineral fertilizer field plot experiment. Results proves that the examined quality parameters suit the requirements of the intervention standard of European Union and international requirements for bread flour at average, but to reach safely the so called milling quality by the Hungarian Standard required higher input, especially mineral fertilizer supply. Results also show that the performance of newly bred and registered varieties is better in numerous parameters in common conditions. Results clearly show that the response of varieties to increasing mineral fertilizer doses is advantageous, and an adequate nutrient supply is guided by the requirements of selected varieties makes the results of quality more secure and the production more economical

This work is about the molybdenum-accumulation of cereals analyzing soil and plant samples from a field experiment set inNagyhörcsök by Kádár et al. in 1991.In this long-term field experiment different levels of soil contamination conditions are simulated. Soil and plant samples were collectedfrom the experiment station to study the behaviour of molybdenum.In this report results of maize, winter wheat, winter barley and soil analysis are presented. The conclusions are as follows:– Analysing soil samples from 1991 we have found that roughly half of the molybdenum dose applied is in the form of NH4-acetate+EDTA soluble– Comparing element content of grain and leaf samples we have experienced that molybdenum accumulation is more considerable in the  vegetative plant parts– Winter wheat accumulated less molybdenum then maize in its vegetative parts. Comparing molybdenum content of winter wheat to winter barley we found that the concentration of the element in wheat was lower by half than in the winter barley. It seemed that molybdenum accumulated to the least degree in winter wheat.
