    Plant clinics play an important role in supporting farmers in growing healthy crops and achieving higher productivity in Nepal. The development and operation of plant clinics in Nepal are assessed in this study through a comprehensive analysis of the institution via literature review and interaction with key stakeholders. The plant clinic approach of the agriculture extension system started in Nepal in 2008, followed up with engagement with CABI and the Government of Nepal. Enhancement of farmers' knowledge and skill, encouraging sustainable farming methods, and ultimately increasing crop yields are the impact of plant clinics. However, there are some challenges faced during the implementation of plant clinics in the existing agricultural extension systems. In Nepal, the plant clinics are primarily operated by agricultural technicians with expertise in plant protection, as well as IPM farmer facilitators and community business facilitators after attending an intensive plant doctor's training. Plant clinics have been integrated into the agricultural extension system by agro-advisory service provider of the government of Nepal. Despite institutionalisation, policy support needs to be strengthened to ensure the sustainability of the different components of the (e.g., data management, validation, monitoring, localised content, etc.) plant clinic in Nepal.

    In my study reveal the situation of the poultry industry. In my research, I used the regularly adopted qualitative method, i.e. the interview. I conversed with the managers of the most important poultry factories, and asked them about the position of the Hungarian poultry sector, the possibility of improving its position, the changes in consumer behaviour, in marketing strategies, means and methods.
    The managers talked about the necessity of collaborating between factories. They agreed on the dominance of commercial chains. In their opinion, these prejudice their chances. They emphasized about the increasing role of processed products and the growing number of sell-stimulated marketing means. The consumer behaviour has changed in the last 10 years too, which helps the market of processed poultry products.

    Before Hungary joined the European Union – in order to gain access to the sources of Structural Funds and to create the expected regional information service – a build up of five-level territorial system was indispensable. Both in the EU and in Hungary, there are significant differences among regions. The aim of regional policy is to reduce differences regarding development and living standards, in order to guarantee a reasonable living standard and income for every region’s inhabitants in the EU.
    In Hungary, during the last decade, the effects of regional difference grew. While the advantage of the leading capital and its agglomeration and the eastern and western parts of Transdanubia was growing, meanwhile the most undeveloped areas' rates of development remained under the mean. The underdeveloped areas are in the northeastern part and in Southern Transdanubia. The developmental differences lead to such great social asymmetries, that these simply beg for remedying.
    In this study, I would like to present the sub-regions of the North Great Plain Region and uncover the possible reasons of the developmental differences.

    The millet is a very special plant with good adaptation that gives the possibility for the late sowing and secondary production. However the effects of late sowing modifies to the efficiency of the agrotechnological elements. The examinations – focused on this aspect – was conducted in the DU CAS RINY in the small plots in four replications in 2013. The largest effect was recorded in the sowing time of the examined factors (sowing time, nutrient supply, growing area). The effectiveness of the agrotechnological elements decreases under unfavourable circumstances caused by the late sowing. The examined factors did not affect in the protein content and milling rate, except in the latest sowing time when protein content was significantly the highest.

    In 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 reduced tillage technologies in corn production based on soil and crop analyses

    Despite new cultivation methods, the proportion of conventionally cultivated land is still very high in Hungary.
    Although these technologies demand more time, labour and fuel, they are still attractive to users because they require less professional skill and simple machinery. In Hungary, conventional tillage methods usually lead to soil deterioration, soil compaction and a decrease in organic content. These side effects have caused gradually strengthening economic and environmental problems.
    The technologies for those plants which are dominant on Hungarian arable lands use (winter wheat, maize, sunflower and barley) need to be improved both in the interest of environmental protection and the reduction of cultivation costs.
    The Department of Land Use at Debrecen University is cooperating with KITE Sc. to carry out soil tillage  experiments at two pilot locations to prove tillage technologies already used in the USA.
    The aim of our examination is to adapt new technological developments and machinery, and to improve them on Hungarian soil for local environmental conditions. With these improved machines, the field growing of plants could be executed by less manipulation and better suited to economic and environmental needs. The most significant task is to investigate and improve the conventional cultivation replacing, new soil-protecting tillage technologies, and to apply no-till and mulch tillage systems.
    On the basis of the experiments’ survey data, we established that the looseness and moisture content of the soil using reduced tillage is more favourable than after using conventional technologies. The results of no-till and shallow spring tillage are behind those of winter plough or disk ripper cultivation in corn yield and production elements.
    To preserve moisture content in the soil, the ground clearing and sowing while simultaneously performing no-till method presents the most favourable results. The surplus moisture gained using no-till technology is equal to 40 mm precipitation.
    Regarding the yield of winter wheat we established that the tillage methods do not affect plant yield. Both disk ripper and conventional disc cultivation showed nearly the same harvest results (5.55 or 5.5 t/ha), where the difference is statistically hardly verifiable from the no-till method. From the individual production of corn and the number of plants planted in unit area,  calculated results prove that no significant difference can be detected between the production of winter plough and disk ripper technology. Although the yield achieved with the no-till method is less than with the previously mentioned technologies, the difference is only 9-10%. We received the lowest production at shallow spring tillage.
    Evaluations have shown a 1.1 t/ha (13%) difference in the yield of maize, between winter tillage and the disk ripper method, in this case the traditional method resulted in higher yield. In winter tillage, the yield of maize was 1.9-2.1 t/ha (23-25%) higher than in the case of direct sowing and cultivator treatments. No significant difference could be noted between the yields of direct sowing and cultivator treatments.
    Our research so far has proved the industrial application of reduced tillage methods in crop cultivation technologies.

    In this paper we analysed the change of the chemical composition and nutritive value of Timothy observed during the spring of 2005. The nutritive value of Timothy was observed between the end of April and the beginning of June relating to the following parameters: crude protein, crude fibre, crude fat, ash, N-free extract, net-energy growth, net-energy lactation, net-energy maintenance, Metabolizable Protein Energy dependent, Metabolizable Protein N-dependent. We also analysed whether a relationship between the environmental factors that affect the
    growing period of grasses and the chemical composition can be detected or not. While testing for correlation, the number of days from 1st January, the amount of heat accumulation, solar radiation and rainfall were considered as independent coefficients.
    For the estimation of weather conditions we calculated the climate index. The observed year can be described as a year with a rainfall above the average and abundant solar radiation. A correlation can be detected between the change of parameters of nutritive value and the quality of the current year. In 2005 the result of the analysis of nutritive value was showed a significance difference with respect to each chemical composition at the rate of P<0.001 depending on the time when the samples were taken.
    According to the outlined data it can be stated that the change of the value of crude protein and ash show decreasing tendency agreeing the research literature. In parallel with the change of nutritive value, the amount of crude fibre and N-free extract increased. However, the value of Net-Energy maintenance showed an alteration only in the first half of the observed period. The same alteration tendency can be detected in the Net-Energy growth and the Net-Energy lactation.

    The 30 years old long-term experiment of Látókép is continued in our experiments. The long-term fertilization experiment was set in 1983, and our sample was taken in spring 2014. The examinations of soil respiration processes and factors that influence soil respiration are required in optimal management. In our study, we interested to know how the growing levels of fertilization influence the microbial processes under nonirrigated and irrigated conditions in maize mono, bi, and triculture. The experimental results and those statistics suggest that the bi and triculture influenced higher microbial activity which was reflected in number of fungus, soil respiration, and microbial biomass carbon (MBC).

    The aim of the study is to determine the effect of vitamin and mineral supplement under permanently high environmental temperature (30±1 °C) on the digestibility of nutrients, performance and furthermore the composition of duck meat in the growing period. A total of four hundred mixed sex 14 days old Cherry Valley type hybrid ducks were used for the study. Two experimental diets were formulated in the study (control and vitamin E, C and zinc supplemented diet). Based on the results the following conclusions were drown: the antioxidant defence system plays an important role in the reduction of heat stress generated lipid peroxidation process. Feed additives which have direct or indirect antioxidant effects can reduce the negative effects of heat stress on the ducks performance and meat composition. Digestibility of nutrients (Dry Matter, Crude Protein, Crude Fat) was not affected by antioxidant supplementation under chronic heat stress (30±1 °C). The performance was affected significantly by Vitamin C and E and zinc supplementation under heat stress (P<0.05). In the treated group the daily weight gain (dWG) increased and the feed conversion ratio (FCR) was improved significantly (P<0.05). The energy and protein conversion was decreased also significantly (P<0.05).

    Distance education, a new teaching method widely-spread in higher education nowadays, requires the extent use of multimedia self-study educational programs besides the traditional means and methods.
    Experience shows that besides certain types of software like encyclopedias, dictionaries, language manuals etc. there is an ever growing demand for appropriate educational programs that can be tailor made, adapted or modified for various kinds of students.
    These programs reflect the teacher’s approach to the subject and contain the relevant, up-to-date information.
    Since they are used in a relatively limited circle, usually within a faculty of an institution or within a single subject area, it is crucially important to be able to produce them with as little energy and time as possible.
    There is a PhD research program, aiming at creating a flexible multimedia framework, that can be a possible solution to the problem. This framework can be easily filled with different teaching materials compiled by certain teachers without advanced knowledge of informatics. The framework itself is carefully designed and guarantees high quality.

    Today, tomato has the second largest harvesting area globally, and the fourth largest in Hungary. The importance of industrial tomato is growing year by year, and one of the most important tasks is to satisfy the needs of the industry. To meet these needs, the producer has to find the proper genotype, which can achieve up to 100 t ha-1 crop yield. This quality has high importance to be researched.

    The experiment was carried out in the Botanical and Exhibition Garden of the University of Debrecen, with 3 examined genotypes. The planting date was 3 of May 2018. The harvesting was two-threaded. On 27 of July the physical parameters – fruit shape index (length/diameter), firmness (kg cm-2), water-soluble dry matter content (Brix%) and weight of the berries (g) – were evaluated. On 15 of August the rheological parameters were examined – the force needed to tear the skin – bioyield point (g) and flesh firmness (g).

    The fruit shape index was oval (between 1.19 and 1.24) for all the examined genotypes. The firmness was between 0.92 (UG1122713 F1) and 1.05(Prestomech F1) kg cm-2, which compliance the needs of the industry. The water-soluble dry matter content was suitable, with a value between 4.49 (Prestomech F1) and 4.65 (UG1122713 F1) Brix%. The weight of the berries was between 45.94 (UG989 F1) and 49.37 (Prestomech F1) g per piece.

    The bioyield point was between 76.00 (UG1122713 F1) and 85.16 (UG989 F1) g. The flesh firmness was between 33.68 (UG1122713 F1) and 42.81 (UG989 F1) g.

    Finally, we can conclude based on the obtained data that the UG989 F1 hybrid was the most proper for the applied cultivation conditions. This genotype can be recommended for the farmers even in extreme weather conditions.

    Several factors influence the quantity and stability of maize yield, the most important being the nutrient supply, the hybrid and precipitation. In 2004, during the maize growing season the precipitation was more than the 30 year’s average, with 68.3 mm, but the distribution was unfavorable. The experiment was carried out in Debrecen at the Experimental Station of the University of Debrecen Centre of Agricultural Sciences, Department of Crop Production and Applied Ecology. We tested 10 various hybrids with their own genetic characteristics for five different fertilizer doses, in addition to the parcels without fertilization.
    The favorable results reached were due to the rainy season. The average yield varied between 7.78-9.67 tha-1. The DK 440, PR37M34, PR38A24, PR39D81 and PR36R10 of the hybrids reacted to higher fertilizer doses with significant growth yields, the yield (more than 11 tha-1) was the highest for N200, P125, K150 fertilizing. The other hybrids, DKC 5211, Mv Vilma and MV Maraton, gave similar results at the N120+PK fertilizer dose and the ensuing doses depressed the yield. Fertilization was more effective thanks to the precipitation. The fourth and fifth dose increased or decreased maize yield depending on the nutrient reaction of the hybrid. The agro-ecological optimum of NPK fertilization was N120, P75, K90 kgha-1.
    During the experiment we tested the moisture loss of five hybrids. The rainy crop year’s effect on the seed moisture content at harvest was higher than in previous years. The seed moisture content hybrids at harvest which have shorter crop years (FAO 300) was 18-19%, and hybrids with longer vegetation periods had more than 20% seed moisture content. DK 440 hybrid had the intensive moisture loss of the five hybrids, at the start of the measurement, the seed moisture content was higher than 40%, and it decreased to 18.6% by harvesting.

  • Bioenergy production: are the objects realistic??

    Currently we do not have the possibility to define our energy reserves, since we do not know the magnitude of extant material resources. The known petroleum (crude) supply will be sufficient for about 100 years at the longest, and according to the latest estimates in 2008 we will reach and even exceed the maximum level of oil extraction, and after this it is going to decrease.
    Hungary has good givens to go upon the way of sustainable energy economy according to experts, however a coherent government policy that lasts for not just one period is essential, and a sound economic- and agricultural policy is needed as well. According to the FVM’s under-secretary in Hungary more than 1 million hectares can be disposable for energy crop production. This would mean that 20 percent of the fields would be taken away from food production and on these fields energy crops would be grown. But we also have to take into consideration that the increase in energy plant production could happen at the expense of food production. If we would like to ensure the food for Hungary’s population from national sources we have to make calculations in determining energy need. In my research I set out the objective to determine the level of that specific turnover and marginal cost which supports the profitability of grain cultivation. With these indicators it is possible to analyze the economy and competitiveness of growing energy crops in the region of the North Plain. The alternatives of using cereals and rational land use should be also considered. A developing bio-fuel program can be a solution for the deduction of excess grain that is typical in Hungary for several years in the cereals sector. The pressure on the national market caused by excess grain can be ceased or moderated, and therefore the storage problems would decrease as well.

  • Evaluation of the current situation of the Hungarian higher education based on a few indexes

    Around the Millennium we experienced the worldwide development and the growing importance of the role of higher education played in the social and economic development. A few years later, however, a crisis appeared in the situation of higher education (Kadocsa, 2002). The Hungarian higher education system faces the perspective of serious changes in its fundamental principals – such as its main activities and the economical ways which are used to finance these activities – even if only parts of the new educational scheme come into effect. Considering this fundamental activity aspect of the issue, there are new challenges which make necessary to rethink the role and aim of higher education and to define the new tasks needed in connection with education, research and other services. Hungarian Education needs to be renewed and improved to avoid a complete
    break away; therefore, future priorities and tasks in order to fulfill these priorities need to be defined (Vincze and Harsányi, 2011). The new conception seems to be based on restrictions of the budget as it is experienced recently: a new structure available for a smaller part of society with a restricted budget has been under development. However, not even a battle, let alone a war can be won without money, horses and arms. The recent financial restrictions as well as the parts of the Széll Kálmán plan concerning education prove that serious amounts of governmental funds is taken away from education. The international improvement tendencies contradict to basically all of these Hungarian priorities.
    All in all, no reform or change – no matter how much wanted – can be achieved without appropriate funds.

  • The importance of millet production in regional production, with special emphasis on climate change

    Regional production is a traditional production structure developed adjusting to the geographical, climatic, biological and soil conditions in given production regions, a certain territorial specification of agricultural production, and a type of farming that best fits the natural conditions and takes the biological needs of plant and animal species into account as fully as possible. The most probable element of risk in plant production is the changeable, extreme weather. That is the reason why the specific characteristics of the place of production and the characteristics of regional production should be considered to a greater extent. The establishment of the range of varieties appropriate for the place of production is the key issue in regional production. One of our historically grown cereal plants that perfectly fits regional production is millet. Due to its short growing season, favourable reproduction ratio and the fact that it is relatively undemanding, it used to be grown in larger quantities in the middle ages. Its good nutritional values made it an important food item, but over time, as a result of industrialisation and technological progress; it has been eclipsed by other cereal crops. In our country it is mainly used to cook porridge, but it is also used in the form of flour and as a base material in the spirit drinks sector. In the recent decades, millet has been applied only in a small area, mostly as a secondary crop in areas that dried out from drainage water in late spring, or as a replacement of extinct sowings due to its late sowing time. Water will be the most significant factor for the future of agriculture, especially considering climate change.
    My examinations took place in the area of the Institutes for Agricultural Research and Educational Farm of University of Debrecen, in the Research Institute of Nyíregyháza, in a small-plot experiment with four replications in 2016.

    In 2021, correlation between relative chlorophyll content and yield in three maize hybrids of different genotypes was examined. The data were collected at the Látókép Experimental Station of the University of Debrecen located on the Hajdúság loess ridge in Hungary. The soil of the small plot field strip plot trial, which was set up in 2011, was calcareous chernozem. Apart from the control treatment (without fertilisation), N fertiliser is applied in the form of base and top dressing. The base fertiliser containing 60 and 120 kg ha-1 N of nutrient applied in spring was followed by top dressing containing +30–30 kg ha-1 N in V6 and V12 phenophases. SPAD values measured at different phenological stages of the growing season increased by an average of about 28% up to 10 leaf stage for all three hybrids. In the pre-silking period (Vn), the relative chlorophyll content decreased by 8% on average. After an average increase of 14% in the tasselling and silking period, SPAD decreased by an average of about 29% at full maturity (R6).

    For the different fertiliser treatments, higher N doses resulted in higher yields. In the basal fertiliser treatment, the A 60 N dose resulted in an average 34% increase in yield, and the A 120 N dose resulted in an average 94% increase in yield compared to the control. The 60 kg ha-1 N basal fertiliser (A60) increased in the V6 phenophase with an additional 30 kg ha-1 N resulted in an average yield increase of 26%. When 120 kg ha-1 N of basal fertiliser (A120) was increased by an additional 30 kg ha-1 N in the V6 phenophase, only the Merida hybrid showed a significant yield increase (7%). No further yield increase was observed when V690 and V6150 treatments were increased by an additional 30 kg ha-1 N in the V12 phenophase. The yield of the Armagnac hybrid decreased by almost 20%, the yield of Fornad by 3% and the yield of Merida by 1%.

    The experiments were carried out in a 2x2 factorial treatments with three replicates, and were completed with 32P phosphorus metabolism measurement. Hungarian Large White x Dutch Landrace growing pigs with 15–18 kg starting live weight were involved in the experiment.
    The experimental scheme was the following:

    Diet consisted of maize and extracted soybean meal. Both components have high phytase content and low phytase activity. 1/a animals received their P-supply according to their needs and 1/b animals got 10% less than their actual P-need in the first part of the experiment.
    In the second part of the experiment both groups (2/a, 2/b) received identical P-supply and 500FTU/kg P supplementation. Apart from P- and phytase-supplementation, the piglets’ diet was identical.
    Total P digestibility was 52% without phytase supplementation, which increases by 4% when P was added according to need and by 12% increase of decreased P-supply. Digestibility of nutrients somewhat increased as effect of phytase supplementation. According to the results of 32P experiments, inorganic P digestibility of MCP was 82–90.8%, which decreases to 73.4–87.2% in case of phytase supplementation.
    Parallel with tendency, native P digestibility of the diet was 31.5–32.2%, which increased to 42.5–54.5% in the case of phytase supplementation.
    Results support the that inorganic P input can be decreased by phytase supplementation and as a consequence P output, the concept and environmental pollution can at the some time be decreased.

    Change in chemical composition and nutritive value of Reed Canary Grass (Phalaroides arundinacea) were investigated in springtime in 2004-2006. The nutritive value of Reed Canary Grass was observed between the end of April and the middle of June relating to the following parameters: crude protein, crude fibre, crude fat, ash, N-free extract, net-energy growth, net-energy maintenance, Metabolizable Protein Energy dependent,
    Metabolizable Protein N-dependent.
    It was also analysed whether a relationship between the climatic factors affecting the growing period as well the chemical composition of grasses and the annual weather were looked for. For the estimation of weather conditions the climate index was calculated. A correlation can be detected between the change of parameters of nutritive value and the quality of the current year. Between 2004 and 2006, the result of the analysis of nutritive value indicated a significant difference with respect to each chemical composition at the rate of P<0.01 depending on the time when the samples were taken. According to the outlined data it can be stated that the change of the value of crude protein and ash show decreasing  endency agreeing the research literature. In parallel with the change of nutritive value, the amount of crude fibre and N-free extract increased. However, the value of Net-Energy maintenance revealed an alteration only in the first half of the observed period. The same alteration tendency can be detected
    in the Net-Energy growth.

     Pigs are the oldest domesticated animals, though their ancestry is still uncertain because of a lack of archaeological and genetic evidence. Pigs serve a vital role in reducing the demand for livestock and livestock products in most parts of the world. Especially in the African continent, pigs serve as mobile cash implying how easily they can be converted into cash to sort pressing family needs. Pig production in Africa is different from advanced systems of production in temperate countries, however, it has similarities with most of the tropical low and middle-income nations. Pig production in Africa requires attention to enable it to contribute effectively to the growing African population. However, it has been orchestrated with a myriad of challenges including market access. This mini-review is designed in a manner to provide an overview of pig production contribution to livelihoods in Africa and associated challenges with possible appropriate solutions.

    As the population of the Earth is constantly growing it generates an unmet demand for protein, which is an urgent problem. The protein extraction process is a potential solution, which offers high-quality plant protein suitable for animal and human nutrition at a favorable price. The process used within our project produces green juice from the green alfalfa biomass through pressing. After the coagulation of protein from this green juice, the by-product is called DPJ (Deproteinized Plant Juices) or brown juice. Our preliminary results match the international literature, namely that brown juice take up as much as 50% of the fresh biomass in weight. To utilize this by-product is a crucial part of the process to make it environmental-friendly and financially viable as well. The examined brown juice samples came from a small-scale experiment of alfalfa varieties carried out in the experimental farm at the University of Debrecen. According to our preliminary results, brown juice has high macro- and micronutrient values, furthermore, it has a potentially high amount of antioxidant compounds. The study highlights that brown juice is suitable as an ingredient in microbiological media, in plant nutrition as a supplementary solution, for feedstock and for preparing human food supplements or functional foods. The potential utilization of all biorefinery products makes it a very appropriate technology for today’s challenges.

    We can get information about water conditions of plane areas by analyzing their relief. By using the Digital Elevation Model, we can get proper information about runoff conditions in the terrain surface, which is the basis for ponding analysis. In our study, a Digital Elevation Model of the sample plot in Hajdúsági-löszhát (loess ridge) was created that makes possible the determination of runoff conditions of the surface. Convergence and divergence of runoff direction showed the rate of ponding and the location of possible inland-water spots. By using this model, concrete location of those areas that tend to be overmoistured could be determined. Knowledge of this phenomenon can be an effective instrument for farmers in optimizing crop growing, and additionally in performing water management interventions in proper time and space.

    The main reason to analyzing the space structure in the Lublin area is to determine the direction and pace of suburbanization in municipalities adjacent to Lublin, distinction factors and motives of population movements to the suburbs, complain rural-urban interaction and multifunctionality of land use. Housing development over the years was accompanied by confusion in planning documents and the law. Changes in regulations on land use in 1994 and 2003 in Poland additionally deepened the negative situation. Local authorities failed to control the spontaneous process of suburbanization, which adversely affected not only the spatial structure of municipalities, but also on local relationship, landscape, land use and the former urban systems. The result are long-term problems associated with incompatibility rural areas to support a growing number of residents, such as failure of the social and technical infrastructure.
