Technical efficiency analysis of maize production: evidence from Ghana
73-79Views:528The study applies the single-stage modelling stochastic frontier approach to investigate the performance of maize farmers in the Ejura-Sekyedumase District of Ghana. It estimates the level of technical efficiency and its determinants for 306 maize farmers. Findings indicated that land, labour and fertilizer influenced output positively whilst agrochemicals and seeds affected output negatively. A wide variation in output was also found among producers of maize. The study further revealed that age, sex and off-farm work activities were significant determinants of technical inefficiencies in production. Results from the maximum likelihood estimate of the frontier model showed that averagely, farmers were 67% technically efficient, implying that 33% of maize yield was not realized. The return to scale which measures the productivity level of farmers was 1.22, suggesting that the farmers are operating at an increasing returns to scale.

Economic analysis of some agrotechnical factors in maize production - a Hungarian case study
5-16Views:405This paper focuses on the economic and statistical evaluation of the production technology findings of the polyfactorial maize production experiments carried out between 2015-2017 at the Látókép Experiment Site of the University of Debrecen, Faculty of Agricultural and Food Sciences and Environmental Management. The examined agrotechnical factors included irrigation, previous crop, tillage, crop density, hybrid and N nutrient supply, while the effect of different crop years was taken into consideration. In addition to descriptive statistical methods, we used multivariate regression analysis during the statistical evaluation. In the course of the evaluation, we examined three models that differed in terms of tillage methods and the consideration of crop year. In our best fit model, the factors were 71% responsible for the change in yield value. We carried out efficiency and comparative analyses in the course of the economic evaluation.
Averaged over the three examined years, it can be stated that nutrient supply and crop year had an outstanding effect on yield, while irrigation had a minimal effect. However, global warming may justify irrigation in the future, not only from a biological point of view, but also from an economic aspect.
Ideal tillage is also greatly affected by crop year, too. Altogether, of the examined tillage systems, subsoiling proved to be the best from an economic point of view.
Our investigations confirm that it is better to perform intensive farming under more favourable market conditions. The optimum of N fertilisation is probably outside of the range we examined, if the extreme changes in maize and fertiliser prices are ignored.JEL Classification: Q16, Q12, Q13, O32

Selection of agricultural land for multifunctional agriculture
49-52Views:126The modern concept of rural development implies the use of agricultural resources, primarily agricultural land, for other (non-agricultural) activities besides its agricultural purpose. The integral aim of this concept of rural development is the maximization of economic results, besides the sustainable development of rural areas, environmental protection and the production of strategic (staple) agricultural products. The objective of this paper is to define the general, theoretical, quantitative model for the determination of the size and quality of agricultural land which, considering the above-mentioned demands (criteria), is optimal for the utilization in agricultural production in certain regions. The remaining agricultural land would be available for the non-agricultural purposes. The economic optimal model for the selection of agricultural land in the traditional agriculture is the model of linear programming. The criteria of the land selection for traditional agriculture are the economic effectiveness (measured by net income or by gross national product) and the economic efficiency (measured by the production economy). The maximum economic effectiveness is determined by the standard method of linear programming and the maximum economy by the method of broken linear programming. The solution of compromise can be determined by multi-criteria programming, based on the minimum differences. The limitation groups in the mentioned variations of the model are: limitations of production quotas of agricultural products, minimum quantities of staple agricultural products, limitations of processing plants in a region (minimum and maximum), limitation of crop rotation, limitations of the needs in animal husbandry for bulky for age and limitations of agricultural land according to various types of utilization. By quantitative defining of the structure and size of agricultural land for traditional agriculture, “the surplus” and structure of agricultural land available for non-agricultural purposes is automatically determined.

Urban Food Crop Farming and Farm Households’ Food Security Status in Oyo State, Nigeria
23-28Views:170Food production and supply has been on the decline in Nigeria with a consequent impact on household food security. This study examined the influence of urban farming on household food security in Oyo State, Nigeria. Multi-stage sampling procedure was used to select 159 farm households in a cross-sectional survey. Structured questionnaire was used to obtain data on socio-economic characteristics, determine the food security status of urban crop farming households in the study area, and examine the effects of urban crop production on households’ food security status. Data were analysed using descriptive statistics while the statistical tools were Food Security Index (FSI) and Probit Regression Model (PRM). Results revealed that 84.9% of the respondents was male, 81.2% married. The average age, household size, and farm size were 49.6 years, 6 persons, 1.1 hectares respectively. Most (75.5%) of the respondents did not have access to consumption credit and 62.3% did not belong to any farmers association. Based on minimum daily energy requirement per adult equivalent of N230.8, 90.6% of the farm households was food secure.
The PRM showed that age (β = -0.1, p<0.05), household size (β= -0.4, p<0.01) and economic efficiency (β = -61.6, p<0.05) reduced the probability of household food security while access to consumption credit (β= 1.7, p<0.05) and allocative efficiency (β = 67.9, p<0.05) increased the probability of household food security. The study concluded that urban farming significantly influence household food security.

Renewable energy resources in Hungary – solid biomass utilization in terms of necessity and opportunity
75-78Views:144In the 21st century a country’s success significantly depends on how it can solve the problems (supply safety, growing prices, climate change, etc.) induced by the application structure of the fossil energy sources with the means of energy saving, energy efficiency and the utilization of renewable energy resources. The utilization of renewable energy sources has positive effects on five key areas: environment protection, energy policies, fulfilment of EU expectations, agriculture and rural development and on the whole of the national economy. The bioenergy – beside fulfilling the national economic aims – it is putting up the value of the role of agriculture and rural development. The role of agriculture is multi-functional in the process. The agricultural sector has an important task in the area of bioenergy to ensure the proper quality and quantity of raw materials for the increase of bioenergy utilization. This also means new sales perspectives and opportunities for the producers. Above all this, the agricultural policy aims for the agriculture and the rural development segment to be the unambiguous winner of the new bioenergy sector and for most of the available profit to stay with the agricultural sector, with the rural players. For this reason encouraging the raw material production it wishes to encourage the producer their primary process and their local utilization. One of the fundamental objectives of the measures is that agriculture should go beyond the raw material production and take steps towards processing and utilization. The multifunctional role in the product chain might mean extra income and more added value for the producers and the active players in the process. The other objective is to promote the local utilization, the scatter of the environmentally friendly energy sources in rural areas, to change the energy is “lying on the ground unutilized” principle while local processing and promoting the utilization, to achieve a lower energy dependency and to optimize and disseminate cost efficient solutions. To realize all this means a great task and a huge challenge for the agricultural government as well as the rural societies and micro regions but might lead to a successful rural development. The range of the tools and measures to fulfil the aims might be very broad, from the regulating instruments to the various subsidies, coordination and dissemination tools. Part of the subsidy schemes are direct production-type of subsidies (the so called direct payments, for example the area based subsidies) and the other main forms are the investment-type subsidies which are for technology development, promotion of competitive production and local processing and for establishing a green energy industry. In the period of 2007-2013 the key elements of the development schemes were drafted in the frame of the New Hungary Rural Development Programme (ÚMVP) and the Environmental Energy Operational Program (KEOP). The available raw materials and the conditions are taken into consideration while designing the development schemes because a successful realization of a product chain means the assurance of the inputs and outputs. The starting point of determining the development direction is the principle of an operation which is sustainable and economical on the long run. In addition such developments are considered reasonable which are viable on medium and long term and bring numerous rural development, environmental and societal returns.

Complex problem analysis of the Hungarian dairy farms
93-100Views:217Hungarian dairy farms went through significant changes in past two decades. The most significant changes were caused by our accession to the European Union in 2004. In Hungary milk production remarkably declined after EU accession due to the decreasing level of support and decreasing milk prices. Size of our dairy herd has been practically reducing since the political transformation (1989); meanwhile the relative yields per cow have been continuously increasing. Relatively low prices, high production costs and tightening quality requirements ousted several producers – mainly small farms - from the market in past years. Feeding cost represents the highest rate in cost structure of production, but animal health expenditures and various losses are also significant. Applied technology of the Hungarian dairies lags behind theWestern-European competitors’; in addition they have handicaps in efficiency and product innovation. Moreover Hungarian milk and milk product consumption is about half of the Union average. In 2007 at the University of Debrecen the opportunities and the problems of this sector were discussed in the framework of a research and development project entitled “Project-generating based on sector-specific innovation”.At this workshop farmers, experts and advisers shared their ideas which were all gathered. The main objective of our paper is to provide useful information for the decision makers and the most important members of the sector. Using the practically successful ideas plus the ideas based on previous experience a new strategic concept was created. To reach the objective of this paper we collected, synthesized and analysed the strengths, weaknesses, opportunities and threats of the dairy farms and performed a SWOT analysis. On the basis of this SWOT analysis we set up a well organised problem hierarchy which would help to identify the main weaknesses of the sector. This analysis gives a great framework for the researches and it also gives a useful tool for the decision makers to improve the competitiveness of the Hungarian dairy sector.

Greener cement sector and potential climate strategy development between 2015-2030 (Hungarian case study)
65-74Views:369Advancing the domestic industrial production towards a sustainable, resource-preserving direction can become an important pillar to support competitiveness in the European Union, as well as in Hungary. Reaching the de-carbonization goals for industrial production via lowering the production volume may result in less desirable macro-economic effects, so decisions which concern the industry require a lot of attention from the climate policy as well. In the case of the cement sector, economic actors have to be motivated to make energy-efficiency investments and technology developments, which also show promise in terms of business efficiency. In the more natural-resource-intensive branches of the industry, both innovations and technological developments will be required to reduce the amount of used non-renewable energy resources, keep it in the industrial cycle, and reduce environmental load. The importance of greener cement will be essential in the near future to reduce the sector’s CO2 emission levels. We need to identify more sector branches which relate to sustainability, which can aid the country in establishing long-term competitiveness that points towards the de-carbonization goals. The cost-efficiency aspects of this development process are the most tedious questions in today’s business planning.

Comparative yield risk calculations of sour cherry and pear varieties regarding risk aversion
111-116Views:118Fruit production in the world is increasing continuously. Though in the past few years China and some South-American countries have extended their fruit producing areas, Europe remains to be one of the greatest fruit producers in the world. In the middle of Europe Hungary has to face several challenges as competing for market. Since yield risk has an important role in Hungarian fruit production we investigate the yield risk of two of the most important sour cherry varieties (’Újfehértói fürtös’ and ’Oblacsinszka’) grown in Újfehértó (1984-2005), moreover, two of the most important pear varieties (’Bosc Beurre’ and ’Williams’) grown in Bánfa and Zalasárszeg (1984-2009). In the examined periods we analyse yield risk with different comparative methods such as E,V-efficiency, first and second degree as well as generalized stochastic dominance methods. We conclude that the production of sour cherry variety ’Oblacsinszka’ in Újfehértó is more preferable compared to the other sour cherry varieties and pear variety ’Bosc Beurre’ in Bánfa is more advantageous than the other pear varieties and sites.

Ecological aspects of increasing intensity in pepper forcing with prime attention to the type of the growing equipment
81-87Views:134Significant amount of profit can be generated in forcing technologies by the efficient use of different elements in growing technologies, however, improving production intensity is on the agenda in the sector. Pepper forcing, as the most significant class of vegetable forcing, practically takes place under all the growing equipment widespread in our country, but there is a considerable difference in context of profitability and efficiency. This paper wonders whether the most intensive technology in pepper forcing is efficient regarding the use of forcing equipment, namely modern greenhouses, or growing under greenhouses with significantly lower investment cost is more efficient. The analysis represents cost-income factors and efficiency assessed on a long-term basis of different technologies via a deterministic model based on producers’ data collections. As a result of the research, economic indicators are calculated based on exact results which will help to conduct a comparative assessment of economic features in technological varieties.

Economic Profitability of Sweet Pepper Production under Different Irrigation Levels and Polyethylene Mulch in a Plastic Greenhouse
109-116Views:169Field experiment was conducted, during two successive seasons of 2014- 2015 and 2015- 2016, at Dokki protected agricultural site, Giza Governorate, Egypt, to study the profitability of different applied irrigation levels and polyethylene (PE) mulch on plant growth and yield of sweet pepper, (Capsicum annum L.) cv. Godion F1, under plastic house condition. Three irrigation levels (0.50, 0.75 and 1.00) of crop evapotranspiration (ETc), using drip irrigation system and three PE mulch treatments (transparent, black and control) were applied. Data revealed that black PE recorded the highest values of early and total fruit yield per plant during the two seasons. Increasing water level up to 1.00 (ETc) enhanced yield with different PE mulch treatments, while water use efficiency (WUE) decreased with increasing water level. However, Using 0.50 (ETc), with different PE mulches increased WUE compared to using 0.75 (ETc) or 1.00 (ETc). The economic assessment of costs and returns from different treatments were calculated. It was found that the average yield was higher in 1.00 ETc with black mulch. Gross margin per 540 m2 were analysed using yield data, price structures and production costs. The 1.00 (ETc) with black mulch had the highest gross margin which is USD 416.8 and USD 533 (1 USD= 9 Egyptian pound) for the first and second seasons, respectively. The benefit cost ratios (BCRs) per 540 m2 were analysed, and 1.00 (ETc) with black mulch had the highest BCR with 1.36 in the first season and 1.45 in the second season.

The analysis of agro-economic effects of household food wastage through the example of bread
9-18Views:219In our busy world, where numerous people starve and where the resources are restricted, it is a key issue to pay particular attention to the topic of prevention and decrease of food loss as well as food wastage.Wastage of food produced and delivered to the end user (customer) is an issue arising globally and nationally as well, which results in efficiency loss at economic level in any case. While the FAO study mentions food waste of the order of 1.3 billion tonnes on a world scale, then the annual quantity of food waste in Hungary is estimated at about 1.8 million tonnes, which contains the waste of every member of the chain from production to consumption. On the basis of the data published by the Hungarian Food Bank (2015), the amount of food waste caused by the population is 400 000 tonnes. In compliance with our objectives, inputs – expressed by non-financial and financial indicators – emerge during production are assigned to the quantity of wasted food. Applying the aforementioned method we would like to make customers realize how many resources (land, water, artificial fertilizer, pesticide, seed and gasoil) are utilized needlessly in food verticum by the end products – at present by different breads they throw out. As our calculations prove by 10% waste of breads the utilization of 5 300 hectares of wheat land and 660 hectares of rye land can be considered unnecessary. By 10% waste of breads the financial value of the utilized resources is altogether 3.25 million EUR. Out of this the financial value of utilized artificial fertilizer is 1.10 million EUR (34%), of utilized pesticide is 1.15 million EUR (35%), of utilized gasoil is 0.70 million EUR (22%) and of utilized seed is 0.30 million EUR (9%). Among different breads, white bread is purchased in the greatest volume by the Hungarian households, from which 121 900 tonnes are bought annually on an average. This quantity is equal to almost the 40% of the annual bread sell. If 10% of purchased white bread is thrown out, it results in useless utilization of 2 676 hectares of wheat land in food verticum. The quantity of utilized water arising form wastage is 15.8 million m3. Further losses emerge as regards material inputs: artificial fertilizer- to the value of 0.50 million EUR, pesticide- to the value of 0.58 million EUR, seed to the value of 0.15 million EUR and gasoil-loss to the value of circa 0.35 million EUR. Totally, material input to the value of 1.58 million EUR is owing to the Hungarian households in case of 10% white bread wastage.

Economic, practical impacts of precision farming – with especial regard to harvesting
141-146Views:151Today agricultural practice is faced with a paradigm shift. In terms of natural resources, the World’s growing population calls for rational management and environment-conscious behaviour. Precision farming may provide a solution for the above mentioned criteria and problems. It has an array of technological equipment, elements and complete systems which are in themselves suitable to create conditions for efficient farming, to reduce environmental load and to provide farmers with optimal return on their investment. Agricultural production has started to focus mainly on efficient crop production and machine operation. Due to this trend, machinery exploitation emerges as a secondary priority for agricultural enterprises. The underlying reason behind this shift is primarily the rise of machinery operation costs. Efficient machinery operation can provide farmers with a solution to reduce their expenditure and through better logistical organization they can obtain extra returns. On the leading edge of my research is to introduce, quantitatively underpin and to justify the application of precision technologies. Our fundamental research methods rely on scenarios and economic calculations.

Energy alternatives in large-scale wastewater treatment
141-146Views:196In my article, after describing the characteristics of recent wastewater treatment activity, I introduce different traditional and innovative energetic opportunities of the compulsory waste management activities at large-scale operational level, covering national and international examples. Furthermore, the wastewater-based biomethane production and the certain plant’s energy self-sufficiency are highlighted topics as well. In the former case, it is possible to utilize the wastewater-based biomethane as fuel (and even to operate own vehicle fleet), while the second one gives the opportunity for the internal usage of produced electricity and waste heat, which can also result in significant cost-savings. As an additional option, algae-based wastewater post treatment is presented, based on the conditions of a Hungarian wastewater treatment plant, which biogas production efficiency and thus energy self-sufficiency has developed favourably due to the technological improvements. These plants may have a twofold role in the future: they are responsible for the compulsory waste management activity and on the other hand they can serve as excellent raw material mines.

Water footprint in Hungary
83-91Views:178More and more news report on water-related extreme environmental phenomena. Some of these are natural, which are often beyond the human race. But others are definitely due to anthropogenic effects. I think the water footprint index is able to highlight national and international water-use processes and gives us the opportunity of organizing a sustainable, consumer-, environmental- and governancefriendly management. 81% of the fresh water withdrawal is from surface water bodies in the EU. In Europe as a whole, 44% of abstraction is used for energy production, 24% for agriculture, 21% for public water supply and 11% for industry. Public water supply is confined to ground waters. To the water resources related human activity caused qualitative and quantitative amortisation will grow worse in the foreseeable future due to the climate change. Beside seasonal differences the sectoral differences are increasingly becoming critical between different areas, such as Southern and Western Europe. The former, wrong agricultural support system has worsened the situation since it gave financial aid for the used improper techniques of water-intensive crop cultivation. By today, this seems to be solved. Public water abstraction is affected by many factors, of which mostly are based on social situation and habits, but technological leakage receives a big role as well. Interesting, that for example the residents’water consumption in Eastern Europe decreased because price were raised and regular measurements were introduced. But in Southern Europe it increased due to tourism in the past period. Industrial water withdrawal decreased across Europe because of the decline of industry and the development of technologies. According to the European Environment Agency (EEA), the Union needs a sustainable, demand-driven leadership which focuses on the preservation and use efficiency. This have already appeared in politics and legal administration as well. Current research calls the attention to the significance and difficulties of this kind of domestic estimation presented trough the water footprint calculation of bread and pork in Hungary. The received data indicate the domestic water consumption trends in a modern approach. There is no doubt for me about the urgent necessity of water footprint calculation because as a result innovative, sustainability supported environmental, social, economical, and political relationships can be created – not just on local, regional or national level, but on interregional, European and even global stage.

Defining the strategic objectives of Hungarian mutton product chain and elements of marketing strategy in the beginning of the second decade of the century
119-132Views:213The sheep sector is regarded to be a “black sheep” in Hungary, both in terms of economy and marketing. On one hand, the sector is not easily traceable as available relevant data are partial and infected by the effects of black market or underground economy; on the other hand, there are no clear, concrete statistical data or surveys on consumption either.
The present study attempts to dissolve the above anomalies and present findings by fact-based model calculations and actual marketing surveys. The fact-based model developed and used for more than 200 variables verifies the correctness of economic calculations. Original examinations were performed by Béla Cehla, doctoral candidate, in 2000–2011. The marketing survey, although not in full accordance with statistical requirements, was carried out in 2012 and it processed relevant data authentically.
The main conclusions are the following: It is clear so far that genetic basis should primarily be evolved in the industry, as it is the factor that mainly contributes to profitability and price-type factors come only following it. Genetic modification is achievable by changing breeds or crossbreeding. The findings of product chain level sensitivity analysis have provided clues that the added value generated in the sector is already determined during slaughter lamb production and progeny influences this value in approximately 80%. Critical points are feed conversion ratio and the relating price of lamb feed, which influence added values by 2.7–2.9%. The remaining factors affect added value through feeding costs, although not considerably.
The following activities can boost interest in the market of sheep products:
• Comprehensive market research
• Stimulation of cultural development by product-tasting, exchanging information and recipes
• Development of supply in accordance with demand
• Identification of target markets, positioning products
• Diversification of product range
• Community trade mark to guarantee excellent quality and Hungarian origin
• Selection of credible poster faces, organization of advertising campaigns -
Effect of uncertainty on farmers decision making: Case of animal manure use
7-13Views:151Due to the high levels of manure application and the poor use efficiency of manure, the European agriculture is held responsible for a considerable negative impact on surface water quality (Langeveld et al., 2007). This problem has emerged particularly in Western-European countries such as the UK, Belgium, The Netherlands and Denmark, facing a large expansion and intensification process in the livestock production since the 1960s (Van der Straeten et al., 2008). Policy measures related to the application of manure on the land encompass two major measures: emission rights, understood as the amount of nutrients which can be applied on the land, differentiated by crop and the N spreading calendars, whereby the manure can only be applied when the crop needs nutrients. The fundamental aim of this pillar is to maximising application rate while avoiding overfertilisation. Maximizing the application rate is related to the economic sustainability of the agricultural sector, by altering the manure surplus, while avoiding overfertilisation is imperative in enhancing ecological sustainability, by preventing nitrate leaching to surface and soil waters. For nitrate policy to meet its target, the farmers should not exceed their emission rights, however make optimal use of their emission right for manure. Consequently, the successful implementation of sink-related measures will strongly depend of the absorptive capacity of farmers towards new ways of nutrient management in general and of animal manures in particular.

Current situation and development of the bee-keeping sector in Hungary
71-74Views:195Rural development has become more and more important issue in Hungary since rural areas also contribute to the efficiency of the national economy. Development of rural areas also very important issue in the European Union, which could contribute to the improvement of profitability of small family businesses, higher employment rate in rural areas as well as slow down the migration of people from rural into urban areas. Nowadays the bee-keeping– as one of the activities can provide alternative income for small businesses in rural areas– has become more and more important topic in Hungary. Bee-keeping sector provides income roughly 15 thousands families in Hungary. At the same time it takes important role in the preservation of rural landscape, traditions and their regional values. However, the sector has serious problems, as well (for instance quality issues, competitors on the market, etc.). It can be stated that the market position of Hungarian honey can be preserved through the improvement of quality assurance and product development. These developments can be carried out by the utilization of national and European Union funds.

Liquid bio-fuels in Hungary: effects and contradictions
89-94Views:139The increase of living standard requires ever more energy, despite energy saving measures. Domestic growth was 100 PJ between 2000 and 2006, and 77% of the total utilization was importe (Hungarian Central Statistical Office, 2008).Sustainability was endangered not only in our energy and commerce policy. Our domestic natural conditions are suitable for plant production; however, the stagnation of the domestic population and decreasing livestock numbers restrict in land marketing. Therefore, significant surpluses from year to year had to be stored and sold abroad, and the fact that the interventional purchase of corn and the expected stringent new EU regulation of the sugar beet sector, make the strategic significance of these branches uncertain. The difficult marketing opportunities make the better utilization of our opportunities in producing liquid bio-fuels possible from marketing aspects, while environmental issues and realizing the EU directions enforce to do so in a longer term. Over the short term, agricultural and competitive aspects will determine its spread, which cause different effects in Europe in comparison with the developing countries. According to Nábrádi-Ficzeréné Nagymihály, 2008, one of the breaking points of Hungarian agriculture lies in the utilization of alternative energy sources. During the past period, many contradictory opinions came forward relating to economies, agricultural effects, food risks as well as the energetic and environmental efficiency of bio-fuels. One thing is certain: these fuels are already used today and their significance has been increasing. Although due to technological development, spread of new products and processes (cellulose-based bioethanol, bioethanol, biogas, hydrogen, biomethane) will obviously have to be expected in the future, at present biodiesel and bioethanol are determent among bio-fuels, thus I deal with these as well as their energetic and agricultural effects in my study.
