Landscape tools to support the educational use of school grounds
63-72Views:32Recent years have seen an increasing emphasis on child-friendly concepts in landscape architecture and urban planning, as well as a growing emphasis on school grounds and environmental education, both in terms of pedagogy and landscape design. School grounds provide places for active engagement with the environment, for experiencing what is taught in class, and, are therefore of particular importance for education and for building children's connection with nature. The aim of this research is to develop a set of landscape architecture tools that can be used to promote child-friendly and education-centered design of school grounds. The research collects and organises the different school ground features, drawing on literature research, and the analysis of the Framework Curriculum. The toolkit presented in this paper lists and evaluates each feature according to its function, its relevance to school subjects and the specific knowledge or skills it can help to acquire, its space requirements and feasibility. To conclude, school grounds offer opportunities for teaching almost any subject and can therefore be linked to educational activities in multiple ways. The results of this research are to be developed into design guidelines in order to be used by designers and teachers alike, to help develop school grounds contributing to the well-being and environmental awareness of new generations.

Economic Aspects of Rural Tourism
55-71Views:73necessary to ensure the livelihoods of those leaving the agricultural sector and to supplement the incomes of those working in agriculture. I research rural development in four settlements in Hajdú-Bihar County, in Balmazújváros, Hortobágy, Tiszacsege and Egyek, all bordering Hortobágy National Park.
There are many alternative income sources in settlements in the Hortobágy area, such as organic farming, production herbs, hungaricums, small animals and arts and crafts, as well as rural tourism. Rural tourism is not for subsistence, but a supplementary income source, mainly available during the summer time. I made a survey of rural hosts in the four examined settlements, and according to my results, I constructed a model reflecting the cost-benefit relation, as well as the payment period conditions of rural tourism. I am going to show whether it is worth dealing with rural tourism, and if yes, under what conditions. Rural tourism contributes to the maintenance of rural modes of living, in this way it has significant cultural, economic, ecological and social aspects, as well. It is crucial for settlements to create the appropriate conditions needed for joining rural tourism, if it is worth joining at all, and to realise investments for all these. Rural tourism has strict requirements for the levels of environment, infrastructure and services. Studying the Western-European practices, Hungary is lagged behind in the conditions of rural tourism and rural hosts have done their activities mainly out of necessity and not to maintain traditions. Rural tourism may result in success only by co-operation and over the long-run. -
Environmental aspects in accounting
127-131Views:153By the strengthening of the economic competition became it apparent a company can’t be valued separate, it should be examined as a complex system. In the assessment of corporate performance is increasingly emphasized the environmental performance. The relevant information of stakeholder about the environmental performance is todays an expection, For this, a management control system is needed, which provide relevant information to managers, hence facilitating the informed decision. This study highlighted, accounting systems are able to meet this demand sufficiently, the accounting means not only the usual bookkeeping, it can be interpreted as a management-controll system, which can help in the valuation of the environmental performance.

Tourism and sustainability in Hungary
135-143Views:84Sustainable development is a very popular conception since many years. In practice there could be many difficulties.
Economic, social and ecological systems are too complex to see all the consequences clearly. After all, sustainable criteria are indispensable for responsible planning.
Tourism is one of the world’s dynamically developing economic sectors. But according to this development, we have to confront with a lot of negative effects, like air pollution, or mass. With globalization, the opportunities for tourism increase: thanks to modern transport, places which were too far to be accessible before are now able to be reached. But there are consequences to this expansion. Unfortunately, growth e.g. in air transport causes considerable environmental damage.
In today’s fast-paced world, the sanctity of nature, a soundproof environment, clean air and rural life have become increasingly important. With the growth of demand and tourism globalized, these values can damage or disappear in a short time. So, in tourism, it is vital to project development plans with sustainable principles.
Just as other countries, in Hungary, the development of sustainable tourism is slowly becoming a priority. Fortunately, in plans for the next few years, there appear more concrete ideas on ways to make sustainable tourism grow.
In my study, I assess Hungary’s position in sustainable tourism, examining how sustainable tourism indicators fit in sustainable development indicators and how can we measure aims of sustainable tourism. -
Effects of a traditional agricultural sector’s decline in less favoured areas
109-114Views:100Due to the effects of economic and political transformations, privatization and accession to the EU, Hungarian agriculture has gone through significant changes in the last two decades. As a result of continuous changes in the economic and regulatory environment, producers have to plan and maintain cultivation and adapt to the changing market needs within continuously changing circumstances. These effects have resulted in a significant decline or in some cases, certain sectors have disappeared. These exercise a negative social and economic effect on all over the country, causing irreversible damages on those regions where agriculture is the only source of living. This paper discusses the effects of breakdown or disappearance of a traditional agricultural sector, namely the tobacco sector.

Special Investment Support Under the Agricultural Reorganisation Programme 1995-2000
64-73Views:76Since the political changes in Hungary, agricultural businesses have worked in a declining economic environment and hectic market situation, with a widening price gap between agricultural and industrial products and low profitability. A declining export comes then by no surprise. The sector has not been able to even benefit from export opportunities provided in the European Agreement. The area least benefiting from quotas is animal products (beef, mutton, lamb, slaughtered chicken, cheese, egg). The ministry of agriculture was lagging behind in responding to these problems, and it was as late as in 1995 when it launched a reorganisation programme for export stocks fund build-up (5).
The author has conducted empirical studies on agricultural enterprises in Csongrád county to see what results the special investment support delivered under the reorganisation programme produced. The fundamental aim of the reorganisation programme for export stocks fund build-up was to boost exportable Hungarian animal product stocks in a bid for businesses to better benefit from the preferential quotas set by the European Agreement. The author examined how the special investment support scheme succeeded in its aims, whether livestock grew considerably in its wake, whether farmers were able to attain exportable quality and what development funds enterprises were able to raise. -
The analysis of the fair data of a solar energy power plant with SPSS
60-63Views:103The use of fossil energy sources greatly damages the environment. Moreover, the quantity of these energy sources is limited. Therefore, it is important to increase the share of renewable energy sources (solar, wind, water and biomass) in energy generation.
Huge amounts of energy (1100-1300 kWh/m2 per year) arrive at the earth from the sun, and are utilized in passive and active ways. One of the active applications is photovoltaic current production, in the course of which electricity is produced directly with PV – panels. This can be fed into a grid. At the University of Debrecen is a solar energy power plant from September 2005 in operation. The electricity performance of the incorporated PV-panels (Kyocera, Dunasolar, and Siemens) are 8.64 kW. The are of PV – panels is 110 square meter. With the aid of the data storage, the tension, current, temperature of the PV-panels, global radiation, air temperature, wind speed, wind direction and the achievement is measured by the ac network.
The effect of the shading on the performance of the PV – panels and the solar energy power plant is examined. The analysis and the graphic representation of the experiment results are carried out with SPSS per grief. We produced per grief. -
The influence of fertilization on the soil characteristics of a calcareous chernozem in a long term experiment
47-52Views:84In the long term fertilization experiment of the University of Debrecen, Centre for Agricultural and Applied Economic Science(CAAEC) (Debrecen Látókép), the effects of a 25-year-long fertilization were examined in terms of some chemical and microbiological properties of soil. With the growing doses of fertilizers, the available nutrient content of soil increased. At the same time the pH significantly decreased, while the hidden acidity increased. Moreover, the ratio between the soil bacteria and microscopic fungi, and the occurrence of microbes also changed. The number of sensitive physiological bacteria groups decreased dramatically. These changes indicate the reactions of living organisms; they correspond to the „resistance stage” of stress effects, but in the case of nitrifying bacteria, they reach the „exhaustion stage”.

Estimation of the vine-shoot yield in the Gyöngyös district
21-26Views:117Every year, a significant amount of vineyard prunings is generated in Hungary. Instead of utilization them, it is burned directly on the field in spite of the limitations of legalization highly pollute the environment in recent decades. The vineyard pruning itself or with other by-products from pomology and forestry can be significant amount of fuel source. However, before the planning to utilization the essential task is to estimate the potential. This study examine that how many vineyard is generated in the micro-region of Gyöngyös in every year on appointed vineyard.
In order to vine-branch potential calculate more accurate data was necessary so the products had to be determined for all plant. Thus, the biomass resource and the utilization become plannable. As the result of the experiment we can estimate that 1,5 t/ha vineyard pruning are generated. It means more than 9 thousand tons pruning in the micro-region of Gyöngyös. This amount can be convert into fuel source more than 150 thousand GJ heating value.
The results evince that the vineyard pruning is important fuel source in every year in the micro-region of Gyöngyös. Further usage is suggested for other regions in other size.

Changes in the relationship between Hungarian Grey cows (Bos primigenius taurus hungaricus) and their calves in the period from calving to four months of age
85-90Views:158The ability of cows to care for their offsprings is a very important trait concerning beef cattle. Maternal instincts are highly influenced by breed, specific cow, and social and rearing environment. In 2020, at the Szamárháti farm of the Tiszatáj Public Foundation, we selected 15 dam-calf pairs and studied them for four months from the birth of the calves. We grouped calf-rearing behaviors according to strength and analyzed the related changes during the program. At the beginning of the relationship, "standing close to each other" (53%) and "suckling" (24%) characterized the pairs. After the first month, "standing or lying separated" grew by 69%, and "vocalization" by both animals fell by 66%. Even though the daily frequency of suckling decreased by 34% as the calves grew older, it remained a typical element of the relationship. Over time, the bond between the animals gradually weakened. This natural process of separation takes a month to complete.

The possibilities of biomass utilization in the field of spatial development
59-63Views:74By joining the European Union, Hungary made a commitment to increasingly utilize renewable energy sources. Keeping in view the agricultural circumstances of Hungary, we can state that biomass utilization has, overall, the greatest range of possibilities to use its products as ‘energy sources’. Biomass raw materials are useful in meeting emission control regulations for environment protection and to reduce climate change. The role of biomass production in spatial and rural development and in rural employment, and also in the decrease of Hungary’s energy dependence, supports development in biomass energy use. My aim in studying biomass utilization is the creation of a micro-regional level, decentralised, agro-energetic system-model for the use of plant and animal biomass for energy purposes, whether naturally or by anthropogenic activity, on agro- and sylvicultural areas, and on animal breeding farms. This model simulation method serves as a planning base for policy-makers during the spatial planning processes. The examination is presently in the stage of data collection. The collection of the basic data of the examination area and the purchase of the necessary equipment, materials and maps has already started. Contact has been made with local stakeholders, municipalities, municipality associations and micro-region managers.

Investigation of the heat shock gene Hsp70 polymorphism in different sheep genotypes
41-45Views:168Nowadays the climate change has an increasing effect on the animals. The warming climate brings up several problems on the area of the animal husbandry, which ones are really important. From the first time the living beings have defensive mechanisms against the heat shock. In current examination we use– from Hungary and from other countries collected –samples of sheep breeds, which are living on different climate. Our fundamental assumption was, that the animals living on other climate adapted to the changes of the environment and there are differeces in their genetic background. These fixed mutations we are looking for in the HSP70 heat shock gene, but we haven’t found any polymorphism yet. We are going to involve further breeds and more individuals in the investigations.

Significance of biogas production in Hungary
127-129Views:127It is known that the quantity of fossil energy sources are rapidly reducing, therefore it is necessary to determine a new direction which has to point directly to renewable energy sources. Increasingly comes into view the agriculture’s energy producing nature next to it’s traditional food producing one. The enviromental protection is connected to the energy production by the ultilization of biomass for energy purposes, within the biogas production has an emphasized importance. Quasi every organic material can be used in biogas production, such as: food processing by-products, manure, sewage sludge, hoousehold waste.

Effect of arsenic treatments on the element content of green peas
203-208Views:210The agricultural environment is contaminated with heavy metals and other toxic elements, which means more and more threats. One of the most important toxic element is the arsenic (As).
The objective of the study was to investigate the effect of As-treatments on the element content of the different parts of the green peas (root,stem, leaf, pod, pea) in the 4. phase of the plant development. Plants were grown in green house. Arsenic was applied in a form of arsenate (As[V]) and the plants were treated with 0, 3, 10, 30, 90 and 270 mg kg-1 arsenic.
According to the results the Ca content of root and pod was increased in the case of the 3 mg kg-1 As-treatment, after that decreasing tendency was observed. In the case of the 270 mg kg-1 As-treatment, the Ca content in the root was increased, because some element is able to concentrate in the lower biomass. The Ca-content of stem and leaves was reduced when the plants were treated with more than 30 mg kg-1 As. The lowest As-treatment (3 mg kg-1) increased the Na content in the root, stem and leaves, however in the case of the higher As-dose, decreasing tendency was observed. In the case of the generative plant parts the 3 mg kg-1 As-treatment also increased the Na content, nevertheless in the case of the higher As-treatments lower Na content was measured, however in the case of the highest As-treatment (270 mg kg-1) the Na content was increased in the generative plant parts, probably the Na was concentrated in the lower biomass. In the case of the 90 and 270 mg kg-1 As-treatment the Mo-content also was increased in the generative plant parts. The 270 mg kg-1 As-treatment caused a similar tendency in the case of the generative plant parts as a result of the lower biomass. In the case of the pod and leaves, the lower As-doses did not cause significant changes.
The Mo content was increased in the root and pea when the plants were treated with 3 mg kg-1 As, but in the case of the higher treatments it was decreased. In the case of the stem it was reverse, the lowest As-tretament (3 mg kg-1) decreased, nevertheless the further As-doses increased the Mo content. -
Education and language teaching in the light of recent social and economic needs
23-29Views:70This paper attempts to describe several general educational potentials that are assumed to facilitate adequate pedagogical response to the recent economic and social paradigm shifts that have resulted in marked changes in the requirements for the labour force on the global job market.
The article describes the most powerful pedagogical trends of the 20th century, selectively concentrating on the assessment of their contribution to and share in the preparation of the inevitably forthcoming paradigm shift in education.
Topic related issues of language teaching in an academic setting are then discussed, focusing particularily on English for Specific Purposes, followed by a more thorough analysis of the major types of ESP syllabi. This analysis attempts to identify those properties that empower ESP teaching to give a more sophisticated answer (as compared to general language teaching) to issues raised by the appearance of new trends and needs in the
global job market.
The paper offers conclusions for consideration as to the responsibility of language teachers and strategy makers in higher education, acting in an intercultural environment. -
The effects of joining The European Union in the area of tourism within health tourism in Hungary
169-177Views:88The occasion of Hungary joining to the European Union caused difficult tasks and questions for tourism in Hungary. Tourism sector must have been prepared for joining to European Union, which means developing a well-functioning and future planning strategy. It has to improve taking parts our tourism into international market without significant deficit. The main aim is achieving the sustainable tourism by approach marketing and environmentally sound of way that is able to become competitive.
My aim is to analyze by numerous indexes what are the effects of joining Hungary to the European Union in tourism sector. However the results need to extend survey into many years. It is very important to reach long-term economic results and development, next to it has to be suitable impacts for social and natural environment, quality of life and developing health tourism as well.
To sum up we can establish extension of European Union area has improved diversity of tourism destination and goods, accessibility of natural and cultural features. -
Arrival of invasive pests in our direct environment and control opportunities
23-26Views:235The author refers about the nowadays applied practical plant protection activities against pests occuring on trees, shrubs and turfs of public domains. It is overviewed those insects, diseases and weeds which cause damages and touched also upon disturbing the local residents only and tasks to the plant protection engineer expert to manage them. Among the special features of public domains should be mentioned that the rules are difficult to harmonize according to the legal, public health, and horticulture requirements at the same time. The anti-pesticide attitude of EU and the modest range of pesticides which are applicable on public domains make difficulties in optimal management work. The author draws up proposals how to manage the complex plant protection on public domains.

Congruency Analyses in Agricultural Organizations
56-61Views:71Management is one of the ancient activities. Managerial behaviour helped humans to become sociable creatures. The aims and roles of management have continually changed along with social and economic changes. Some management theories in the early literature interpret the managerial function as „to instruct” and „to control” subordinates. The manager – having the appropriate authority – unilaterally appoints the expected activities in accordance with the objectives of the organization and his/her own wish. Its form is the instruction or the command.
Later, organizations and management theories defined the managerial function rather as the impact on the employees than (or instead of) a unilateral manifestation of will. These focus on collaboration and imitation instead of on obedience. These theories were based on the fact that the employees work hard to succeed in meeting organizational goals because they want to meet their own needs, desires and wishes.
Today, management means being in a relationship with colleagues, effective and successful working methods and, last but not least, commitment and liability for the company. The responsibilities of directors are to estimate the employees’ competences and to apply the workforce expediently.
In our opinion, the two most important questions of human resource management (HRM) will be:
• the expectations made of the manager by the subordinates,
• the expectations made of the subordinates by the manager.
The expectations of management have continuously evolved along with the social, political and economical improvement. We consider the most important requirements will be the following:
• the exploitation of employees’ abilities (especially the leaders’),
• the exploitation of human resource,
• aim-oriented leadership related to different management levels.
The actual research covers only the examination of managerial requirements. We experienced that the expectations are affected by many factors starting with the fulfillment of a specific task to the social environment as a whole. Managements of the last century did not require such self-reliance, creativity and broad knowledge from their subordinates as they do today. Employees have to be able to adapt to new tasks, technology and methods; have to react quickly against the problems; and be loyal to the company and the manager.
We plan to expand our research backwards as well, in which we will search for the answer what kind of expectations are formulated by subordinates on the manager. Thus, we can approach and reveal the expectations (the examined factors) from two sides.
Due to this method, we would like to work out such coherences which can help us to demonstrate the opinions of the differently qualified employees of the organisations. The applied method provides us facilities to carry it out in various organisational parameters, such as functional form, size, effectiveness, range of activity. -
Nest-site preference of Hooded Crow (Corvus cornix L.) in Debrecen, Hungary
13-17Views:149In the past decade, the population of the Hooded Crow has shown significant growth in Debrecen, Hungary. The aim of this study was to become acquainted with the nest-site selection behavior of Hooded Crows in urban spaces. While our research revealed that the Hooded Crow is not particular when it comes to selecting among tree species for nesting, we did notice differences regarding nesting height. Hooded Crows living in the city build their nests higher up than those living outside Debrecen’s city limits. We also discovered a slight, insignificant difference between nesting heights and tree species, which is probably due to the different characteristics of the given tree species. As for nesting heights, we found that in typical urban habitats there were no relevant differences. However, when we compared these habitats in pairs, it came to light that nesting heights -when comparing solitary trees - wood segments and tree rows - wooded segments- did show significant differences, which can be explained by the various conditions provided by the habitats mentioned.
In summary, the following results emerged from our research:
1. The Hooded Crow prefers approximately the same nesting heights in all kinds of habitats, urban environment and tree species.
2. The nesting height does not significantly depend on the habitat itself or on the tree species. -
Examination of the current and idel organisational culture and leadership elements at the municipalities of the North Great Plain region
117-125Views:139The connection between organizational culture and leadership has been examined by several researchers (Schein, Schmircik, Bass) and it is proven that there is a link between them. The leader shapes the organizational culture and at the same time the organizational culture shapes the leader too. The middle managers of local governments place the major emphasis on the dimension of goal orientation for the future. From the leadership perspective they find charismatic, goal and team oriented leadership necessary for the future.
The local governments have to answer the challenges of the rapidly changing environment. Quick responses and adjustments are only possible if the leader possesses a clear future vision and not only sets short-term goals but plans for the future and estimates the necessities on the long run. It is important to have a leadership with utmost dedication to the organization and to the objectives of the organization. The leaders must raise the interests of the employees, involve them in the process of setting goals and in finding ways to meet those goals, and that the employees should no longer strive to realize their own personal ambitions but focus on the common objectives. This brought transformational leadership to light.
The leader establishes and shapes the organizational culture but the individuals and teams working for the organization have impact on the organizational culture as well. This becomes apparent in the organizational culture as middle managers would place the major emphasis on performance orientation. Performance orientation is a dominant motivation based on excellence, hard work, pre-calculated risk, fore planning, goal orientation and regular feedback, which shapes the leadership too, as the leader has to change as well, in order to run the organization.
Scheins’ standpoint reflects the best the relationship between the organizational culture and the leadership. Schein claims that organizational culture and leadership are interwoven phenomena, as the leader shapes the culture but after a while the organizational culture itself shapes the leader too.

Alternatives of synthetic chemicals – chemicals derived from foods and related materials
291-303Views:131Foods are composed of numerous chemicals, each of them work individually or synergistically inside the living organism for a specific reaction supporting the life processes. To date, the efficacy of these chemicals in industrial processes has been explored to a limited extent. In fact, chemicals derived from food have great potential to be used in multi-disciplinary sciences and in numerous applications. Synthetic chemicals might be replaced by the natural resources in the future which will also reduce the environmental impact of hazardous and toxic chemicals. The present article gathers a few examples of chemicals derived from food or related materials and shows how worthy they are in various fields, ranging from radiopharmaceuticals to alternative mining of precious metals. In a nutshell, the article puts forward a few simple ways through which research may adjoin the greener mandates and help in maintaining the sustainability of our environment.

A genetic study regarding the number of grains in spike in winter wheat
19-22Views:65Grain number per spike was studed in 6 winter wheat varieties and all their 30 direct and reciprocal F1 hybrids. Parents
included 4 released Romanian variety, the old american Atlas 66 and a dwarf breeding line, Oradea 79. This line has a low number of
grains/spike, but is important in breeding program for here reduced height. General and specific combining abilities were computed and
genetic effects were estimated using Griffing’s method 1, model 1, as modified by Cabulea (1983).
For this diallel crosses, gene interactions and the interaction between cytoplasm and nuclear genes were highly significant and
the ratio of additive and non-additive effects was close to one.
The variety Fundulea 29 showed the highest general combining ability and it is recommended as a good parent for increasing
grain number/spike. Mid-parent heterosis was significant in 9 out of the 30 cases, mostly in hybrids involving the breeding line Oradea 79.
In 3 cases the number of grains/spike of F1 hybrids was significantly lower than the average of the parents. The breeding line Oradea 79 had
a significant negative general combining ability, but showed significant positive specific combining ability in most crosses, as well as a
significant positive effect of its cytoplasm. These results are considered to indicate that there are chances of improving the grain
number/spike in some crosses with Oradea 79. -
Hungary’s correspondence with the EU regulations regarding liquid bio fuels
119-128Views:77During the recent years researchers from different countries have found that our environment is at risk. It has been recognised by the leaders of the member countries and they have made decisions together concerning environmental protection in several agreements, contracts. Unfortunately, these decisions have been weakened and adumbrated on numerous occasions by certain interests.
However, the energetic exploitation of the biomass has been supported by the economic and social changes of the previous years, more specifically, that of the bio fuels. The significant increase in the price of the traditional energy sources, the import dependency of the countries, the foreseeable exhaustion of the resources, the changes occurred due to joining the EU are all such problems that facilitates the application of bio fuels, as a good solution.
Our country decided to modify the then existed bio fuel component rate of 2% to 5.75% which has to be achieved by 2010. Since then, in March 2007 it has been expanded to 10% until 2020 (concerning energy content). This decision was taken knowing that this year (2006) the bio fuel rate has been 0.5%. However, the rate of 2% has not been achieved even in the EU. One can understand that the implementation cannot be fulfilled without significant political decisions and support. The main reason for this is that the price of bio fuels is not competitive with the present fossil-origin energy prices in Hungary. So in 2007 several regulations were modified. The most important one is perhaps the regulation of the revenue tax, which caused the successful tax-differentiation concerning bio fuels in more member states between 2007 and 2008. Its essence is that the revenue tax is not decreased, but if the fuel does not contain a bio fuel component of 4.4 bulking percentage per litre, „punishment” tax has to be paid. Moreover, on behalf of the implementation, regulations concerning bio fuels and bio fuel components are improving
At present the production and the application of bio fuels without any support are not economical yet. That is why it is important to emphasize the support policy of our country. After joining the Union, the new members can receive some shares from the direct disbursements, but only a tan increasing rate, we can achieve the 100% in 2013, though there is an opportunity for national contribution. Energy plants produced in agriculture receive separate supplementary support which is an advantageous opportunity for the farmers of the sector. Bio fuels cannot only be supported through agriculture, of course, but by research development, investment etc.
All in all, it can be concluded that Hungary seeks to fulfil the EU responsibilities taken and by this, to contribute to the maintenance of the sustainable progress, decrease of environmental pollution and the import dependency of energy sources. -
Challenges and limtations of site specific crop production applications of wheat and maize
101-104Views:131The development and implementation of precision agriculture or site-specific farming has been made possible by combining the Global Positioning System (GPS) and the Geographic Information Systems (GIS). Site specific agronomic applications are of high importance concerning the efficiency of management in crop production as well as the protection and maintenance of environment and nature. Precision crop production management techniques were applied at four locations to evaluate their impact on small plot units sown by wheat (Triticum aestivum L.) and maize (Zea mays L.) in a Hungarian national case study. The results obtained suggest the applicability of the site specific management techniques, however the crops studied responded in a different way concerning the impact of applications. Maize had a stronger response regarding grain yield and weed canopy. Wheat was responding better than maize concerning plant density and protein content performance.
