TL;DR: Tartamkiserletben et al. as mentioned in this paper proposed a kulonboző tapanyagszintek befolyasoltak az uszog-es a csőfuzarium-fertőzes, a szardőles, valamint a Push-teszt erteke es a termes nagysaga.
Abstract: Osszefoglalas Tartamkiserletben, csernozjom talajon, a Hajdusagban vizsgaltuk, hogy adott tőszam (60 ezer/ha) eseten a kulonboző tapanyagszintek hatasara, valamint, hogy adott tragyaszint mellett (N120P90K90) a kulonboző tőszamok hatasara hogyan valtozik a kukorica novenyek magassaga, az uszogfertőzes, a csőfuzarium-fertőzes, a szardőles, valamint a Push-teszt erteke es a termes nagysaga. Vizsgalataink a 2010. ev adatait tartalmazzak. Vetesvaltas eseten harom modell kerult beallitasra (mono-, bi-[buza, kukorica], trikultura [borso, buza, kukorica]). A kezelesekben ot tapanyagszintet (kontroll [kezeletlen], N60P45K45, N120P90K90, N180P135K135, N240P180K180) es harom allomanysűrűsegi erteket alkalmaztunk (40 ezer/ha, 60 ezer/ha, 80 ezer/ha). A novekvő tragyaadagok hatasara N240+PK tapanyagszintig szignifikansan nőtt a novenymagassag, N240P180K180 tapanyagszinten vetesvaltastol fuggően 247,0–286,4 cm kozotti ertekeket mertunk. A kulonboző tapanyagszintek befolyasoltak az uszog-es a csőfuzarium-fertőzes, a sz...

TL;DR: In this paper, the effects of crop rotation, nutrien supply and crop protection technologies, as well as the appearan ce of the main earand leafdiseases (powdery mildew, helminthosporium leaf spo t, leaf rust, fusarium) were studied on the crop yi elds of winter wheat variety MV Pálma during the 2009/2010 crop year.
Abstract: The effects of crop rotation, nutrien supply and cr op protection technologies, as well as the appearan ce of the main earand leafdiseases (powdery mildew, helminthosporium leaf spo t, leaf rust, fusarium) were studied on the crop yi elds of winter wheat variety MV Pálma during the 2009/2010 crop year. The experimen ts were conducted in triculture (pea – wheat – corn ) a d biculture (wheat – corn), at five nutrition levels, with the use of three crop p rotection technologies (extensive, conventional and intensive) at the Látókép Research Site of the University of Debrecen, Centre of Agricultural Sciences. Our results proved that the appearance of leafand ear-diseases were significant in the wheat cultures during the 2009/2 010 crop year, because of the rainy, warmer than us ual weather, the lodging, and the huge vegetative mass developed. The most severe infectio s by the four examined diseases after pea and corn pr e-crops were observed at extensive crop protection levels, when fertilizers were used at the highest dose. Following corn pre-crop, in the case of all the thr ee crop protection technologies the maximum rate of wheat yield results were achieved at N150+PK level. The highest yield was reached at intensi ve crop protection level (6079 kg ha ). In triculture, in case of all the three crop protection technologies the maximum yields were ach ieved at N50+PK level; in extensive technology 5041 kg·ha -1 yield, in conventional technology 6190 kg ha -1 yield was realised, while in the intensive technolo gical model the yield was 7228 kg ha . The relationship between yield and fertilizer amoun ts, the rate of pathogen contaminations, crop prote ction technologies and pre-crops was defined with correlation analysis in case of di f erent crop rotations during the 2009/2010 crop ye ar. Based on the results of the experiment, we found that in stands after corn precrop strong positive correlation was established be tween the crop protection level and the crop yield (0.543), the nutrient levels and the eme rgence of the four examined pathogens, and between the utrient levels and the yield (0.639). Extremly strong positive correlation was o bserved between crop protection and yield (0.843) i n triculture. Strong positive correlation was detected between the nutrient level s and the presence of the four examined pathogens, as well as between nutrient and lodging (0.688). Strong negative correlation was be tween the crop protection level and the four examin ed diseases both in biculture and triculture.

TL;DR: The research proved that the previous crop fundamentally determines size, rate and dynamics of the dry matter formation in the spring time vegetation period and the interaction effect of leaf area index, weight of dry matter and fertilization resulted in the maximum yield in biculture and triculture.
Abstract: The research focused on the effects of previous cropping and fertilizers on the LAI, rhythm of the dry matter, leaf disease intensity and amount of yield. Long term field experiments’ results proved that the previous crop fundamentally determines size, rate and dynamics of the dry matter formation in the spring time vegetation period. The LAI index and crop results of winter wheat can be influenced mainly by raising the fertilizer amount. N fertilization has an outstanding role in the changes in leaf area index (LAI), weight of dry matter and yield of winter wheat. According to our results, the interaction effect of leaf area index, weight of dry matter and fertilization resulted in the maximum yield in biculture and triculture. Keywords—Crop rotation, Leaf Area Index, leaf disease of winter wheat.
