Cím:The investigation of the biological basis and yield-forming elements in maize in a comparativ experiment on hybrids / Becze Zsófia, Sárvári Mihály
Dátum:2013
Megjegyzések:Hybrid selection and the application of hybrid specific production technologies are important in terms of the increase of the yield and crop safety of maize. The main explanation for this is climate change, since weather extremes are going on and seem to accelerate in Hungary too. The spring of 2013 can be characterized as of great amount of precipitation, in the third month, the fivefold of the 30-year average fell. In 2013, in the case of each hybrid, longer ears were observed. We can conclude that during the droughty 2012, lower ears with lesser grains were developed in the case of every hybrid. In 2013, the weather was more favourable during the period of grain-filling and development, therefore the hybrids not only produced longer ears but significantly more grains were developed in one row.

Cím:Study of water management under bi- and triculture wheat populations in a long-term field experiment / Dóka Lajos Fülöp
Dátum:2015
ISSN:1224-6255 2065-3484
Megjegyzések:The present studies were executed in a poly-factorial long-term field experiment set up in 1983. Winter wheat was used as test plant. Studies were executed in both bi-(maize-wheat) and tri-culture (maize-pea-wheat) crop rotation systems in two crop years (2012 and 2013). Nutrient supply level of N100+PK was applied in the experiment. The dynamic change of soil moisture content (expressed in V/V%) of the upper 200cm soil layer during the vegetation period of winter wheat from sowing until harvest, just as the water supply deficit values of the vegetation period were studied. Based on our results it has been stated that the water stock of the chernozem soil was significantly affected by crop rotation ?beside other influencing factors (weather conditions, nutrient supply, tillage). Regarding the two studied crop rotation system slower soil moisture content values expressed as volume percent were calculated for the triculture crop rotation system.

Dátum:2014
ISSN:1224-6255
Megjegyzések:The research was set up on chernozem soil at the Látókép research area of the University of Debrecen in Hungary. We examined the yield and the yield production per 1 kg NPK fertilizer utilization of hybrid PR37N01, PR37M81and SY Afinity in 2013. We found that SY Afinity produced the most yield at the level of N120+P (18,619 kg ha-1) while PR37M81 reached the highest yield at level N150+PK (16,754 kg ha-1). Studies related to yield production per 1 kg NPK indicated that the best results were achieved at level N30+PK compared to the control treatment. Yield production per 1 kg NPK was17.6 kg kg-1 by PR37N01, 44.2 kg kg-1 by PR37M81and 25.6 kg kg-1 by SY Afinity.

Dátum:2013
Megjegyzések:Our experiment was set up at the MÉK Látókép AGTC KIT research area of the University ofDebrecen, Hungary on chernozem soil. The study focused on the yield and plant height of maizehybrid SY Afinity, SE4410 and PR37M81 at various nutrient treatments in 2012. We found out thatnutrient level N150+PK was optimal for hybrid SY Afinity (14.105 kg ha-1) and SE4410 (13.849 kgha-1), while hybrid PR37M81 preferred level N120+PK as the examined hybrids gave the best yieldresults at the above mentioned nutrient levels. Plant height records shown that SY Afinity's initialdevelopment phase was the strongest as at the time of the first record (18th May) this hybridperformed the best results at all nutrient levels. Hybrid SY Afinity and SE4410 reached its maximumheight at N120+PK while hybrid PR37M81 at N150+PK.

Cím:Effect of ecological and agrotechnical factors on the phytopathological properties of sunflower (Helianthus annuus L.) / Novák Adrienn, Pepó Péter
Dátum:2015
ISSN:1224-6255 2065-3484
Megjegyzések:The research work has been carried out at the Látókép Research Site of the University of Debrecen, Centre for Agricultural Sciences, Farm and Regional Research Institute on calcareous chernozem soil in. We examined the effects of sowing times and the fungicide treatments on the phytopathogenic characteristics phytopathological properties of sunflower hybrids. In order to characterize the phytopathological properties of sunflower hybrids in a complex way infection index (Ii) has been elaborated. The infection of sunflower populations by fungal phytopathogenes was mainly determined by the weather conditions of the crop year. The development of infection indexes depended mainly on the sowing time in the studied crop years (r=-0.806**, r=-0.755**). Fungicide application had significant contribution to the moderation of the unfavourable effect of sowing time in both years and thus it decreased the infection index of sunflower populations (r=-0.464**, r=-0.578**). Plant phytopathogenes resulted in significant yield loss in sunflower populations only in the crop year of 2012 that was characterized by heavy infection.

Cím:Investigation of sowing technology in sunflower (Helianthus annuus L.) / Novák Adrienn
Dátum:2014
ISSN:2065-3484
Megjegyzések:The yield and maximal leaf area index of three sunflower hybrids (P64LC09, Paraiso 1000, ES Tektonic) were studied in two crop protection models with different input levels (extensive=without fungicide treatments, mid-tech= two fungicide treatments) on chernozem soil in two different years (2012 and 2013). A field experiment was set up at the experimental farm of the University of Debrecen, at Látókép on calcareous chernozem soil. The highest LAI values were measured in the beginning of July for all the three hybrids in the case of both cropyears. During our investigation, the yield results of the cropyear 2012 (1828-3602 kg ha-1) were significantly below those of the cropyear of 2013 (4292-5902 kg ha-1). With respect to the yield amount, the higher plant density (55000 plant ha-1) were optimal.

Cím:How to improve the agronomic efficiency in precision maize production / Pepó Péter, Fekete Ágnes, Vad Attilla
Dátum:2018
ISSN:1224-6255 2065-3484
Megjegyzések:Nowadays the most important challenge is in crop production how to reduce the huge industrial inputs and how to improve the agronomic efficiency of technology. The one of the best way is to use the agrotechnical elements of precision technology. The effects of different crop management factors were studied in long-term experiments on chernozem soil in Eastern Hungary (Debrecen). In sustainable maize production the fertilization resulted high yield surpluses in average (2.0-4.1 t ha-1) and rainy (2.1-5.4 t ha-1) crop year (LTE2). Our scientific results proved that the modern maize genotypes had high maximum yields (15.4-16.6 t ha-1). The maximum yield of maize hybrids depended on fertilizer doses and plant density. We founded a special interaction between fertilization and plant density: in higher plant density we had to use higher dose of fertilizer (LTE1). In Nopt+PK treatment we obtained higher WUE values (36.6-46.9 kg ha-1) comparing with control treatment (28.7-33.6 kg ha-1) in maize production.

Cím:Agrometeorological and agrotechnical risks in maize (Zea mays L.) production / Pepó Péter, Tótin Ákos
Dátum:2015
ISSN:1224-6255 2065-3484
Megjegyzések:Maize has high productivity and produces hudge vegetative and generative phytomass, but maize is very sensitive to agroecological (mainly to climatic, partly to pedological conditions) and agrotechnical circumstances. In Hungary maize is grown on 1,1-1,2 million hectars, the national average yields vary between 4-7 t ha-1 depending on the year and the intensity of production technology. The crop rotation, fertilization and plant density on the yields of maize were investigated in dry and wet cropyears in a long-term experiments on chernozem soil. The water-supplies were rainfed and irrigated. In dry cropyear the yield-surpluses of irrigation were 2.8-4.2t ha-1, in the cropyear characterized by average-goodwater supply the yield increasements of irrigation varied between 0.7-2.1 t ha-1, respectively. The yield-increasements of irrigation were mainly modified by crop rotation and fertilization. The optimum plant density of maize was different in the rainfed and irrigated crop technology on chernozem soil.The maximum LAI values of maize (4.0-4.8 m2m-2) were in middle July and the SPAD values were on high level (56-59) between early July and middle August in maize production.

Cím:Fertilization and sowing time as the environmental risk factors in winter oilseed rape (Brassica napus var. napus f. biennis L.) production / Pepó Péter, Vincze Éva
Dátum:2015
ISSN:1224-6255
Megjegyzések:We have investigated the fertilizer response of oilseed rape on the chernozem soil in Eastern Hungary. Our research results proved that oilseed rape is has high fertilizer (N+PK) demand. In the experiments, N = 210 kg ha-1 +PK proved to be the optimal fertilizer dose. The yield increasing effect of fertilization was 800 to 1300 kg ha-1, depending on the cropyear. The maximum yield (5000 kg ha-1) was obtained in the cropyear of the less infection. The results of our studies confirmed that the hybrid rape was of excellent adaptivity to the sowing time; due to this fact, the yield decrease was minimal (0-270 kg ha-1) in the middle September sowing time compared to the late August one. According to the results of the Pearson's correlation analysis, strong correlation (0.6*-0.9**) was found between the spring precipitation and temperature and the most important diseases (Sclerotinia, Alternaria, Peronospora, Phoma) of oilseed rape. The sowing time had more significant effect on the LAI oilseed rape and moderated effect on the relative chlorophyll content (SPAD).

ISSN:1224-6255
Megjegyzések:Fertilization responses of winter wheat (Triticum aestivum L.) genotypes (GK Öthalom, Euclide, Mv Toldi, Pannonikus) were studied in a long-term experiment on chernozem soil in 2011-2013 cropyears. Our scientific results proved that there were variety-specific differences among the winter wheat varieties in natural nutrient utilization, maximum yields and yield-surpluses. The infections of leaf diseases of wheat were influenced by cropyears and genotypes. In the application of wheat crop models the variety-specific fertilization is the most important agrotechnical elements.
