A búzaliszt ásványianyag- és fehérjetartalmának változása műtrágyázás hatására ; Changes in mineral and protein content of wheat flour due to fertilizers
Jelen dolgozatban a K, P, S, Mg, Ca, Fe, Mn, Zn, Cu, Sr Ă©s a fehĂ©rje mennyisĂ©gi alakulását vizsgáltuk kĂĽlönbözĹ‘ adagĂş NPK kezelĂ©sek mellett az egysĂ©ges Országos Műtrágyázási Tartam kĂsĂ©rletek nagyhörcsöki kĂsĂ©rleti állomásárĂłl származĂł bĂşzaliszt mintákban. A minták elemtartalmának meghatározása induktĂv csatolásĂş plazma tömegspektromĂ©terrel törtĂ©nt, amelyet a minták oldatba vitele elĹ‘zött meg HN03-H20 2-os nedves roncsolás formájában. A fehĂ©rjetartalmat Khjeldal mĂłdszerrel határoztuk meg. A kezelĂ©sek hatásának szignifikanciáját kĂ©t mintás t-prĂłbával vizsgáltuk. EredmĂ©nyeink szerint a javulĂł N ellátás nem befolyásolta a liszt K-, P-, Mg- Ă©s Fe-tartalmát, viszont pozitĂv hatással volt a S, Ca, Cu, Mn Ă©s Sr dĂşsulására. A szuperfoszfát adagok Ă©s a liszt K-, S-, Mg-, Ca-, Fe- Ă©s fehĂ©rjetartalma között nem találtunk összefĂĽggĂ©st, azonban a S mennyisĂ©ge növekvĹ‘ tendenciát mutatott, emellett a javulĂł P ellátással nĹ‘tt a lisztek P-, Mn- Ă©s Sr-koncentráciĂłja, viszont a P kezelĂ©sek gátolták a Zn- Ă©s a Cu-akkumuláciĂłját. A K dĂłzisok Ă©s a minták K-, P-, S-, Mg-, Fe-, Mn-, Zn-, Cu- Ă©s fehĂ©rjetartalma között nem találtunk kapcsolatot, azonban a javulĂł K ellátás negatĂvan befolyásolta a liszt CaĂ©s Sr-koncentráciĂłját. In this study the effect of different NPK doses on the contents of K, P, S, Mg, Ca, Fe, Mn, Zn, Cu, Sr and protein were investigated in the flour of winter wheat. Samples were collected from Nagyhörcsök which is one of the experimental stations of the Hungarian National Long-term Fertilization Trials. The elements content of samples were measured using inductively coupled plasma optical emission spectrometer followed by digestion with HN03-H202 solution. The protein content was determined using Khjeldal method. The statistical analysis of the effect of NPK treatments was made using statistical method of independent samples T-test. It was proved that N treatments caused significant difference in the amount of Ca, Cu and Sr (P<0,05) and there were strong significant correlation between N fertilizer and S, Mn and protein content of flours. The superphosphat had strong positive significant effect (P<0,01) on the P, Mn, and Sr content and positive significant effect (P<0,05) on the Sr concentration but strong negative significant influence (P<0,01) on the amount of Zn and Cu in the flour. K fertilization reduced the accumulation of Ca and Sr
Effect of molybdenum treatment on the element uptake of food crops in a long-term field experiment
Molybdenum, as a constituent of several important enzymes, is an essential microelement. It can be found in all kind of food naturally at lowlevels. However, environmental pollution, from natural or anthropogenic sources, can lead to high levels of the metal in plants. Our study is based on long-term field experiments at Nagyhörcsök, where different levels of soil contamination conditions are simulated. Plant samples were collected from the experiment station to study the behavior of elements: uptake by and transport within the plants, accumulation in different organs, phytotoxicity and effects on the quantity and quality of the crop. In this study, we present the effect of molybdenum treatment on the uptake of other elements. Molybdenum is proved to be in an antagonist relationship with copper and sulphur, while molybdenum-phosphorus is a synergist interaction. However, in most of the plants we studied, increasing molybdenum-treatment enhanced cadmium uptake. We found the most significant cadmium accumulation in the case of pea, spinach and red beet.

In this study the effect of different growing places and NPK doses on the contents of P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, Sr and protein were investigated in the whole grain and flour of winter wheat (Triticum aestivum L.). Plant samples were collected of the year 2001, 2002, 2004 and 2005. Samples were harvested and collected from five experimental sites of the Hungarian National Long-term Fertilization Trials which were set up in 1966 to study the effect of different NPK levels. These sites are as follows: Iregszemcse, Karcag, Kompolt, Nagyhörcsök and Putnok. These experimental fields have different soil types and climatic conditions. The element content of samples were measured using inductively coupled plasma optical emission spectrometer (ICP-OES) followed by digestion with HNO3-H2O2 solution. The protein content was determined using Khjeldal method. Data analysis was done using SPSS for Windows 13.0 software package. During investigation of the effect of different growing areas on the element and protein content of the whole grains and flours, all data were subjected to ANOVA method and after detection of significant differences (p<0.05) data were subjected to Duncan’s test to allow separation of means. The analysis of the effect of NPK treatments was made using statistical method of independent samples T-test.
The effect of NPK fertilizer on the Netto Protein Ratio of wheat and peas had been also examined through animal feeding experiment. Amino acid composition of samples has been also determined.d
A környezeti nevelés bemutatása két hajdú-bihar megyei középfokú oktatási intézmény programján keresztül
A környezetszennyezĂ©s hatásai nemzedĂ©keken keresztĂĽl átĂvelĹ‘ problĂ©mákat jelentenek. Az emberisĂ©g felismerte, hogy a termĂ©szet egyensĂşlyának megĂłvása mindnyájunk közös Ă©rdeke, ezĂ©rt a feladat társadalmi összefogást igĂ©nyel, aminek alapvetĹ‘ feltĂ©tele a környezettudatos szemlĂ©letmĂłd. Ennek kialakĂtására a családon belĂĽl törtĂ©nĹ‘ nevelĂ©s során is megfelelĹ‘ hangsĂşlyt kell fektetni, de mivel ez sok esetben nem Ăgy törtĂ©nik, az iskoláknak is nagy a felelĹ‘ssĂ©ge, ebbĹ‘l kifolyĂłlag az intĂ©zmĂ©nyi keretek között törtĂ©nĹ‘ oktatás folyamán a környezettudatos szemlĂ©let formálására a kezdetektĹ‘l fogva törekedni kell. Dolgozatomban a formális keretek között zajlĂł környezeti nevelĂ©st vizsgáltam kĂ©t olyan hajdĂş-bihar megyei közĂ©piskolában, ahol 15-19 Ă©ves tanulĂłk szakirányĂş kĂ©pzĂ©se zajlik. Adataimat a Pallagon találhatĂł Debreceni Egyetem Balásházy János GyakorlĂł SzakközĂ©piskolája, Gimnáziuma Ă©s KollĂ©giumában, illetve a hajdĂşböszörmĂ©nyi Veress Ferenc SzakkĂ©pzĹ‘ Iskolában gyűjtöttem.
Munkám során elĹ‘ször az iskolák környezetnevelĂ©si programját mutattam be, majd az intĂ©zmĂ©nyek tanárainak vĂ©lemĂ©nyĂ©t, az általam kĂ©szĂtett kĂ©rdĹ‘Ăvre adott válaszaik elemzĂ©sĂ©n keresztĂĽl. Ezt a kĂ©t környezetnevelĂ©si program SWOT-analĂzise követte, az elĹ‘zetes eredmĂ©nyek tĂĽkrĂ©ben.rĂ©gi kĂ©pzĂ©sagrár mĂ©rnöktaná
The effect of different fertilizer treatments on the sulphur and protein content of wheat
In this study the effect of N,P and K nutrients on the S and protein content of wheat grains was investigated in a long-term fertilization experiment set up in Nagyhörcsök. The calcareous chernozem soil having the following characteristics: pH (KCl): 7.3, CaCO3: 4.27%, humus: 3.45%, Al-soluble P2O5 and K2O: 60–80 and 180–200, KCl- Mg: 150–180, KCl+EDTA-soluble Mn-, Cu- and Zn-content: 80–150, 2–3 and 1–2 mg kg-1. The experiment had a split-split-plot design with 40 treatments in 4 replications. Plant samples were collected from 2002 and 2004. 2002 was a drought year while 2004 was very wet.The main conclusions are as follows:– The sulphur and protein content were than the control higher in every NPK treatments.– The sulphur and protein content of the wheat grains were higher in 2004 that had a lot of rain than in 2002 that had drouht

Molybdenum - accumulation dynamics of cereals on calcareous chernozem soil
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
