The effect of fertilization and plant protection in sunflower (Helianthus annuus L.) production
57-63Views:275Sunflower is the most important oil crop in Europe which is grown on the biggest area of all the oil crops. The area of producing sunflowers in Hungary was changing to 524–704 thousand hectares in the past decade in comparison with approximately 100 thousand hectares in the 1970’s. In our experiment different sunflower hybrids were examined. The doses of fertilizers were the following in 2017 and 2018: 0–30–90–150 kg ha-1 N, 0-50-90-90 kg ha-1 P2O5 and 0–70–110–110 kg ha-1 K2O. Three different treatments of plant protection were used in the experiment to protect them from fungal infections. A rise in the dosage of nitrogen resulted in increasing infection. The biggest fungal infection was identified in 150 kg ha-1 N, 90 kg ha-1 P2O5 and 110 kg ha-1 K2O treatment. The largest infection was measured on plots without plant protection at the highest N doses, both in leaf and disc diseases. We measured the highest 41.25% in 2017 and 53.1% in 2018 Diaporthe helianthi infection, and 24.5% in 2017 and 25.5 % in 2018 Sclerotinia sclerotiorum disc infection in these plots. kg ha-1
Average yield was changing between 2.96–4.67 t ha-1 in 2017/2018. The lowest yield was obtained in the absolute control plot (without plant protection and without nutrient) in both years, which was 2.96 t ha-1 in 2017 and 3.14 t ha-1. The yields increased due to growing nutrient supply and excellent plant protection. The highest yields were 3.67 t ha-1 in 2017 and 4.67 t ha-1 in 2018 (150 kg ha-1 N, 90 kg ha-1 P2O5 and 110 kg K2O active substance). Purpose of the experiment at analysing the impact of different treatments on the profitability of sunflower production.

Examination of the impact of ecological and agrotechnical factors in a maize fertilisation experiment
13-17Views:126The year 2013 was rather extreme breeding year because of the uneven distribution of precipitaion and the summer heat. The experiment was set on with eight different genetic characteristics maize hybrids in 2013. In our study were included different kind of breeding season hybrids. We studied the effect of NKP fertilization and row spacing on the yield. The fertilizer doses are based on 25-year long-term experiment. Compared to control, the N40+PK treatment has also achieved a significant yield increase, although some hybrid of increasing fertilizer doses yield response to loss. The majority of hybrids reached higher yields using the 50 cm row spacing. The water release of hybrids was measured between 21th August and 17th September weekly, at the same time points. The rainy September slowed ripening hybrids and water release, so the grain wet content at harvest showed higher values.

Examination of Possibilities for Increasing Sugar Content
202-206Views:46The result of sugar beet production is highly effected by the quality and the yield. Those agricultural techniques are very important which can be applied at low cost to improve these parameters. Such an opportunity is to increase sugar yield by foliar fertilization with nutrients and by treatment with bioactive fungicides.
In my small block trial I examined the effect of the magnesium and strobilurin active ingredients in different combinations and at different application times on the quality and the yield of sugar beet.
I found that there was a signifficant increase in sugar content on that blocks which were treated with a bioactive ingredient combined with magnesium in the middle of July and on those which were sprayed with bioactive ingredient in August. -
Statistical comparison of soil analysing results of chernozem soils
93-99Views:151The soil fertility was degraded as a result of unreasonable tillage, therefore the application of site-specific nutrient replacement is necessary. It is essential for the application of precision fertilization to know the location, extension, soil properties and nutrient-supply of the different soil types of
cultivated areas.
We collected soil samples from 580 hectares of land in 2006. Soil samples were collected from every 5 ha in 30 and 60 cm depths during Spring from 20.05.2006 to 12.06.2006 and again in Autumn from 09.19.2006 to 02.10.2006. Soil samples were analysed at the Department of Agricultural Chemistry and Soil Science of DE-ATC.
The two examined soils are slightly calcareous, weakly saline, poor in zinc. The calcareous chernozem soil is slightly acid, the content of humus, nitrogen, phosphorus and potassium is medium in this soil. The meadow chernozem soil is slightly alkaline, and properly supplied with humus and potassium, and middling supplied with nitrogen and phosphorus. The meadow chernozem soil is more heterogenous in soil plasticity, lime, saline, nitrogen phosphorus and potassium content and less heterogenous in pH and zinc content than the calcareous chernozem soil.
Standard deviation of measured values in pH, soil plasticity, humus and nitrogen content significantly differ between the examined soil types. The soil plasticity, pH, humus, nitrogen and zinc content significantly differ among calcareous chernozem soil and meadow chernozem soil, but the difference in phosphorus content can be statistically proven only in case of Spring soil sampling. -
The influence of climatic conditions of the harvest year on the wheat quality
23-25Views:135Technological potential of wheat bread depends on the variety, manner and type of fertilizer, irrigation conditions and climatic conditions in their absence. This study was done on two varieties of wheat grown in Bihor county in a place with identical fertilization conditions, for two different years: year 2014 can be characterized by a greater quantity of rainfall during the wheat vegetation period and the year 2015 can be characterized by a drought during the growing wheat on the subject of the study. In the study was examined whether climatic conditions have any influence on the technological potential of wheat, not taking into account the data on quantity produced per hectare in the years studied.

Self Pollination and Fruit Quality-Comparative Research of Sweet Cherry Cultivars
295-299Views:138In fruit production – among stone fruits – sweet cherry is considered to have great promise, but species of sweet cherry need improvement. Cherry plantations are advanced in years, therefore putting into operation high productivity plantations is an important field of research. Through clonal selection and cross-breeding, several new cherry species were created in the recent past in Hungary. Spread of these species is also important. In our factorial cherry production, we use high trunk trees and trees with large crowns. Intensive plantations are very few in number.
Our goal is to study the morphological and physiological properties of new sweet cherry cultivars. The most important aim is to combine the productive area of foliage and the fruit quality. The present study shows the self pollination, fruit setting and fruit quality parameters. -

Study of the microbiological activity in the agrocenosis from Crisurilor Plain
73-77Views:126The seasonal variations of soil microorganisms depend on changes in the soil chemical properties and the microbiological processes of soil are determined in main by different cropping systems, soil management and season. Investigation of the microbiological properties of a haplic luvisol, under different cultivation conditions showed that anthropogenic factors such as fertilization and treatments with pesticides was favourable for certain microorganisms while others were inhibited by these factors. In order the quantitative occurence of microorganism was aerobic mesophilic heterotrophs (105–107 cellsxg-1 dry matter soil) were followed by Actinomycetes, yeast and mould (103–106 cellsxg-1 dry matter soil), nitrogen fixing bacteria (102–105 cellsxg-1 dry matter soil) and nitrifying bacteria (10-1–103 cellsxg-1 dry matter soil). The highest values of aerobic mesophilic heterotrophs were found in cropland and undisturbed meadow of haplic luvisol. Actinomycetes are more developed in undisturbed soils than in the cultivated soils. The number of yeast and mould was high in the apricot tree orchard, and Azotobacter and nitrifying bacteria were identified in a small number in all the soil variants studied. Among the total number of aerobic microorganisms, pH and humus content statistically proved relationship was established. Total number of yeast and mould depends on the proportion of 10.89% by moisture content and pH. The numerical presence of Azotobacter depends in a proportion of 9.6% by the ammonia nitrogen content and pH variations. The numerical presence of nitrifying bacteria depends in a proportion of 1.69% by the nitric nitrogen content and humus content variation.

Technological development of sustainable maize production and its effect on yield stability
379-388Views:213In 2015 and 2016, we examined the effect of NPK nutrients, sowing date and plant density on yield on typical meadow soil. The amount of precipitation was 282.0 mm in 2015 (January–September), 706.0 mm in 2016 and the 30-year averageis 445.8 mm.Agrotechnical factors:– Experiment a)5 Dow AgroSciences hybrid with three sowing dates and three plant densities– Experiment b)In 2015 eight, in 2016 ten hybrids with different genetic characteristics and growing seasons, with control (without fertilization), N80+PK and N160+PKtreatments, five plant densities (50–90 thousand) with 10 thousand plants difference between the different densities.
In a drought year, we reached the higher yield in the earlier sowing date and with the lower lower plant density of 70 thousand plants ha-1-. The maximum yield, depending on the agrotechnical factors, was 10–12 t ha-1 in 2015, while in 2016 it was 14–16 t ha-1. Yield stability can be increased using hybrid-specific cultivation techniques. -
Evaluation of the correlation between SPAD readings and absolute chlorophyll content of maize under different nitrogen supply conditions
121-126Views:442Currently, one of the most important objectives of agriculture is to maintain the principles of the sustainability. The use of precision technologies in agriculture belongs to this topic. The use of precision technologies is increasingly widespread in the cultivation of various agricultural crops, including maize. Sensing is an important part of these techniques. In our experiment we compared two methods: measuring relative chlorophyll content and the method of determine the extractable chlorophylls. The experimental plant was maize (Zea mays L.) and the measurements were performed at an early development stage (V8) of three genotypes. Three levels of nitrogen (0; 80; 160 kg ha-1) were applied during the experiment. The relative chlorophyll content was measured by SPAD-502 (Minolta, Japan) and a handheld GreenSeeker (Trimble, USA) device. The extractable total chlorophyll content decreased in parallel with the increased nitrogen level. The obtained SPAD values were diversified furthermore the NDVI values have not been changed for the effect of different nitrogen fertilization. In the early stages of development of maize, these parameters need to be complemented with other measurements to provide reliable information about the crops nitrogen status.

The role of green manure crops in Hungarian plant production
49-53Views:253According to the data of KSH (Hungarian Central Statistical Office), the sowing area of cereals in the crop year 2016 was over 2.56 million ha, on which winter wheat and maize were produced in a rate of around 50–50%. Regarding these data it is obvious that the domestic cropping structure has been simplified and become unilateral. This unfavourable crop rotation system causes several problems. The number of Hungarian livestock decreased in the past decades. The amount of manure was 24 million tons in 1960, but only hardly 4.5 million tons of organic manure was applied in 2016. Therefore, the importance of other possibilities, alternatives for organic matter recovery have become enhanced. This is especially important from the aspect of sustainable plant production. The fact that the European Union has introduced new directives for subsidiaries in 2015 has to be noted as well.
The objective of the set experiment is to find new technological solutions that are suitable for the execution of sustainable plant production by inadequate crop rotation, organic substance recovery conditions or under more unfavourable climatic conditions.

Effect of different production types on the yield and ß-carotene content of sweet potato /cultivar Ásotthalmi- 12/
45-49Views:178Production of sweet potato is extending in Hungary, despite the fact that there is no field-specific production technology. Therefore, many growers cannot utilize potential yields and quality. The goal of this study was to determine the optimal production method of the Ásotthalmi 12, a Hungarian sweet potato cultivar which can adapt to the Hungarian climate. The effect of single and twin rows production on the yield of this cultivar was examined. The planting was carried out on June 24th, the harvesting on October 20th and the growing-season was 120 days long. Uniform nutrient supply was applied to the whole field experiment. During basic fertilization, 206 kg Knd 20 kg N, 36 kg P ha-1 were used on the soil. While forming the ridges, we used an additional 25 kg N, 45 kg P and 62.5 kg K ha-1. We adopted drip tape irrigation on the experimental field. After the planting, from the 8th week of the vegetation, another 21 kg ha-1 K, 10 kg ha-1 MgSO4, and 2 kg ha-1 Ca(NO3)2 was added in one dosage weekly, until the 13th week of vegetation. At the evaluation of the experiment, we examined the yield regarding the whole experimental plot. SPAD and fluorescence measurements were carried out on 08.16. 2019, 08.28.2019, and on 09.13.2019, during the watering break. To demonstrate the difference between the dates, we applied ANOVA and Tukey post-hoc tests. For the measurement of phytonutrients HPLC, a liquid chromatograph was used, where the carotenoid content of the Ásotthalmi 12 cultivar was determined in connection with the different production methods. Test results showed that twin rows production leads to a nearly 30% greater yield, than single row production. We determined, that the growth of yield correlates negatively to the ß-carotene content of the Ásotthalmi 12 cultivar sweet potato.

Fertilisation Effect on Quantity of 0.01 M CaCl2 Soluble N-Forms in a Long-Term-Small-Plot Experiment
166-170Views:61long-term experiments have an opportunity to investigate the effects of fertilization and plant nutrition. The paper reports the results achieved in the 39th years of a long-term-small-plot fertilisation and liming experiment set up on acidic sandy brown forest soil in the Nyírség region. From the 32 treatment, four replications, altogether 128 plot experiments with 10 treatments are summarized. We took samples after harvest of triticale, in August.
We used a reliable method (segmented continuous flow analysis) to determine different (easily mobilized - 0.01 M CaCl2 soluble) N-forms of soil. The 0.01 M CaCl2 soluble inorganic and total N content and the UV digestable organic-N form of soil were determined by this method.
The results are summarized below:
– The mineralized-N (Nmin.) content of soil increased with dose of nitrogen treatment. Liming treatments increase the amount of Nmin.
– The maximum content of easily mobilize organic-N-fraction was found in the upper (0-20 cm) layer. This fact due to the large amount of crop and roots.
– Changing of content of 0.01 M CaCl2 soluble total-N-forms due to N doses.
– The ratios of these N forms are variable. It is very important that the content of organic N fraction is not negligible and this fraction plays a main role in the plant nutrition. -
Product orientated sewage sludge composting technologies in the practice of AKSD Ltd.
33-36Views:159In recent years the regulations of the EU unambiguously determine that the biodegradable wastes should be used for biogas production or composting. The direct use of sewage sludge in agriculture is limited by its hazardous microelement content, but it can be used effectively in composting. The limitation parameters can be extinguished with correct compost-mixture and technology variants. The exact determination of the technologies and mixtures result a stable, constant quality product. The compost, as a classified product, is friable structured. The end-product is a
homogeneous mould with good water capacity, does not contain any weed seeds and pathogenic organisms. The compost does not have a acidify effect on the soil. It is an effective fertilizer thanks to its macro and microelement content. -
The effect of different fertilizer treatments on the sulphur and protein content of wheat
73-76Views:160In 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. -
Evaluate the nutritional reaction at winter wheat after different forecrops
77-80Views:140Our field researches took place on the Látókép test farm of Agricultural Science Centre of University of Debrecen, Centre for Agricultural and Applied Economic Sciences, in long-term experiment, on calcareous chernozem soil, in growing season of 2014/2015. In our experiment we examined the fertilizer reaction and the yield of different winter wheat genotypes (GK Öthalom, GK Csillag, Mv Csárdás, Mv Toldi) with grain maize and sweetcorn forecrops. According to our results, the sweetcorn forecrop strongly affected the yield. In the average of the fertilizer treatments and the varieties, after sweetcorn forecrop 6.9 t ha-1, after grain maize forecrop 5.4 t ha-1 average yield was gained. According to our data, the fertilizer reactions of the varieties were significantly different.

The effects of different planting methods on sweet potato
173-177Views:288The aim of our research program is to develop the production technology and to examine the possibilities of the utilization of sweet potato (Ipomea batatas (L.) Lam.). In 2016 and 2017, production technology experiments were set up with four replications in a randomized block design on an alluvial soil in Deszk, Hungary. In our field experiments, we obtained results of planting material production, planting methods and the optimized fertilization of sweet potato. Experimental plots were set up either with or without ridges. In heavy soils – where usually ridge planting is preferred –, in 2016, the production technology without ridges proved to be more effective. In 2017, however, we got opposite results: based on the result of the harvest, the production technology with ridges proved to be more effective. The transplants originating from cuttings from tubers (primary transplants) or from shoots (secondary transplants) did not show significant differences, however, in both years, yield levels were higher on ridges with secondary transplants.
Sweet potato yield may vary widely among producers due to improper ridging and planting orientation. The aim of this study was to establish the proper ridging and planting orientation, so as to enhance constant reliable yields among sweet potato producing farmers.

The analysis of flour blends as affected by the behaviour of two different quality flours of triticale under different fertilizer treatments
5-8Views:223Triticale is likely used in many countries in human consumption, due to its advantageous agronomical and nutritional properties mostly in blends. The baking quality of blends depends not just on the proportions of the used flours but also on their individual quality what can be influenced by fertilizer treatments.
22 flour blends were prepared with commercial wheat flour and triticale wholemeal flour in proportions from 0% to 100%. The triticale was treated with different amount of fertilizers (N30P30K30, N60P0K0). Changes of wet gluten contents and extensograph parameters of the blends were determined. The quality of blends significantly depends on the fertilizer treatment of triticale beside the proportions of the flours. When the N60P0K0 treated triticale was used in blends, wet gluten and extensibility values were significantly higher, but in case of resistant to extensions (Rmax) the N30P30K30 treated samples gave higher values. The measured values of wet gluten and extensibility were above the expected values (synergism), while in the case of resistance to extension the expected values were higher than the measured values (antagonism).

Yield components of hairy vetch (Vicia villosa Roth.) in different sowing technologies on acidic sandy soil
83-88Views:293Nearly a quarter of the agricultural utilized area of our country is made up of sandy soils. Sandy soils are poor in nutrients, and, therefore, the effectiveness of farming is basically determined by the method of maintaining soil fertility and the fertilization practice.
The hairy vetch called Vicia villosa Roth (Sandy Roth.), also known as a sand pioneer, plays a significant role in the exploitation of sandy soils. Its cultivation was started in Hungary in the late 1800s. It is primarily used as green fodder, most recently as a green manure and as a soil protection plant. The lupine is grown mainly as a supportive plant, which was previously rye, and today it is triticale. The ratio of the two plants to each other and the spatial location of plants depend on the method of sowing.
The aim of our work was to present the yields of some of the grain grown in different sowing methods and some of its crops.

The applicability of 10 ml cryotubes for sperm cryopreservation in a Hungarian carp landrace (Cyprinus carpio carpio morpha accuminatus)
93-97Views:251In our study, the comparison of 5 ml straw and 10 ml cryotube during sperm cryopreservation in a Hungarian carp landrace (Cyprinus carpio carpio morpha accuminatus) was carried out. Three different dilution ratios (1:1, 1:4 and 1:9) were also tested using the cryotube. A significantly higher pMOT was recorded using the cryotube in comparison with the straw. VCL and STR were similar in both groups. Cryopreservation had a negative effect on pMOT and VCl using the cryotube and also the straw where, STR was not reduced significantly. An increasing tendency was observed using higher dilution of sperm during cryopreservation; however, significant difference was not recorded between the three groups. VCL and STR were similar in all groups. Cryotube was applicable for the sperm cryopreservation of the Hungarian carp landrace. However, the standardization for the freezing method specified for this volume is recommended. The different dilution ratios needed be tested also during fertilization.

Effect of tillage practices, fertilizer treatments and crop rotation on yield of maize (Zea mays L.) hybrids
43-48Views:208This research was conducted at the University of Debrecen Látókép Research Station and is part of an ongoing long-term polyfactorial experiment. The impact of three tillage systems (Mouldboard plowing-MT, Strip tillage-ST, Ripper tillage-RT) and two levels of fertilizer treatments (N80 kg ha-1, N160 kg ha-1) along with a control (N0 kg ha-1) on the yield of maize hybrids (Armagnac- FAO 490 & Loupiac-FAO 380) cultivated in rotation with winter wheat was evaluated during a two-year period (2017–2018).
Amongst the three tillage treatments evaluated, ripper tillage (RT) had the highest average yield (10.14 t ha-1) followed by mouldboard tillage (MT) and strip tillage (ST) with 9.84 and 9.21 t ha-1 respectively. Yield difference between RT and MT was not significant (P>0.05), as compared to ST (P<0.05). Soil moisture content varied significantly with tillage practices and was highest in ST, followed by RT and MT (ST>RT>MT). Yield of RT was 7–9% higher than MT in monoculture plots, while MT reign superior in biculture plots (monoculture: RT>MT>ST; biculture: MT>RT>ST).
A positive interaction between tillage and fertilization was observed, with higher yield variation (CV=40.70) in the non-fertilized (N0) plots, compared to those which received the N80 (CV=19.50) and N160 kg ha-1 (CV=11.59) treatments.
Incremental yield gain from increase fertilizer dosages was significantly higher in monoculture, compared to biculture. There was no significant difference in yield between N160 and N80 in the biculture plots (12.29 vs 12.02 t ha-1). However, in monoculture plots, N160 yield was 23% higher than the N80 kg ha-1 (N160=11.74 vs N80=9.56 t ha-1).
Mean yield of maize in rotation with winter wheat was 28% (2.47 tons) higher than monoculture maize. The greatest benefit of crop rotation was observed in the control plots (N0) with an incremental yield gain of 4.39 tons ha-1 over monculture maize (9.92 vs 5.43 t ha-1).
Yield increased with higher fertilizer dosages in irrigated plots. Fertilizer application greatly increased the yield of maize and accounted for 48.9% of yield variances. The highest yield (11.92 t ha-1) was obtained with N160 kg ha-1 treatment, followed by N80 kg ha-1 (10.38 t ha-1) and N0 kg ha-1 (6.89 t ha-1) respectively.
Overall mean yield difference between the two hybrids was not statistically significant, however, yield of FAO 380 was 3.9% higher (9.06 vs. 8.72 t ha-1) than FAO 490 in monoculture plots, while in biculture plots, FAO 490 was 4.1% higher than FAO 380.
Average yield in 2018 was 13.6% (1.24 t ha-1) higher than 2017 for the same set of agrotechnical inputs, thus, highlighting the significant effect of cropyear.
Armagnac (FAO 490) cultivated in rotation with winter wheat, under ripper tillage and N80 kg ha-1 is the best combination of treatments for optimum yield.

The Role of Cultivation Systems in Quality Sugar Beet Production
134-138Views:139Producing sugar beet, as it is a demanding field crop, has contributed to the raising standard of plant production. It has an outstanding place among the plants that are cultivated in the intensive plant production system. Rentability of sugar manufacture is determined by the stability of yield and the quality (saccharose content) of sugar beet. In this way, the fundamental interest both of the producers and the processing industry is high yield and quality, year by year. The yield and the quality of the sugar beet are mainly determined by the plant production system, so we studied the effect of fertilization, irrigation and plant protection.
