Agrochemicals and food safety
(Dr. Ottó Pálmai)
Under the present conditions of production we cannot afford to avoid using chemicals, among them pesticides and fertilizers. At the same time, it means that up-to-date food safety conditions cannot do without working out the principles of and implementing good agricultural practice (GAP). It is an urgent task to perform. The article gives a brief summary of the contradiction between intensive production and the concomitant overproduction, and the sustainable and environmentally friendly agricultural production. The author deals with the role of fertilizers and pesticides, the institutional background of food safety, and finally outlines what needs doing urgently here.

Thoughts before accessing the EU about the lists of recommended varieties
(Dr. László Lajkó)
The value of varieties will be raised in Hungary in the near future. The enlargement of the European Union will involve legal disappearance of national frontiers regarding plant varieties. Preparation and publication of recommended lists of varieties by independent organisations is a common practice in the EU, as they provide the most comprehensive information in connection with the selection of varieties for growers. Choosing the varieties, taking natural, agronomic and market conditions of the country into consideration, needs to be assisted also in Hungary as a future member state. The recommended lists of varieties must be prepared also in our country in the next few years. However, such list can play its important part well only if, the related ministry, the Agricultural Chamber and the plant product boards, as well as the participants of economic life jointly do their best for the establishment and efficient management of the system.

Study. Grapevine decline, „esca” disease
(Teréz Dula)
The comprehensive paper deals with the global problem of grapevine growers: early decline. The first part of the study summarises general information on the related diseases. After reviewing theoretical bases, the author discusses the decline of young plants then early decline of bearing vineyards. It is followed by summarising limited possibilities of control. The second part of the article gives an account of the diseases based on practical examples taken from two important wine-growing districts (Eger and the foot of Mátra hills), considers the causes, the importance of infected propagating material and the urgent tasks to be done. Several colour photos complete the study.

Results of vineyard registry in county Bács-Kiskun in 2001
(Gabriella Elek)
The establishment of the vineyard registry has been mandatory in the EU member states since 1962. At the beginning, only the most essential data for the regulation of the common wine market had to be collected. However, since 1979 the overall survey of vineyards must be made every ten years in each member state. In Hungary the Government Decision 2198/1998 (IX. 9.) provided for the mandatory data recording of the Hungarian orchards and vineyards till the date of our accession to the European Union, and based on it, a registry in compliance with EU standards shall be established. The article summarises the data for county Bács-Kiskun. The registry of the vineyards and the evaluation of data from various aspects contribute to planning and organising production related to these vineyards, market flexibility and sales. In addition, they serve as a basis for long-term strategic decisions and call the attention to relationships at national level.


Agriculture and operation of machinery
(Dr. Lajos Gockler)
The future of Hungarian agriculture depends on whether we can be duly cost-efficient and will be able to improve productivity or not. As in 2004 Hungary will likely be a member of the European Union, we have to meet EU requirements and enter into competition with the members states of longer history in the Community, whose agriculture will receive almost twice as much compensation support in the future, too than the currently accessing countries. However, we will be able to hold on in the competition only if our production costs are lower than their ones in spite of the less support. Depending on the circumstances, operation of machinery accounts for about 30-70% of agricultural production costs, which is a remarkable share. Unfortunately, production has considerably decreased in the past 10-15 years due to the changes occurred in agriculture, while costs have conspicuously increased. One of its main causes, says the author, is the too small farm size. He believes that the way of reducing production costs is to form larger farming units, consolidating and integrating land-strips. He supports his opinion with a lot of statistical data and comprehensive tables.

Operation of plant protection machines
(Dr. Zoltán Csizmazia)
In the former issues of Agrofórum, the author dealt with preparing plant protection machines for the season and their adjustment. Now he gives detailed information on the operation of such machines. He emphasizes that unsuccessful, bad work can be done even with a well-adjusted sprayer possessing up-to-date technical parameters, if the basic rules of operation are neglected. Certain characteristics of the machine need to be known for professional working quality. In this respect, the most important one is the spraying pattern and the related knowledge. The author separately discusses operation of field crop and orchard sprayers.

Nitrogen fertilizer application in the past and today, in Hungary and Europe
(Dr. Tamás Németh)
Nutrient balance for nitrogen and potassium of Hungarian field crop production became positive from the second part, while for phosphorous, from the first part of the 1960s. This period with annual positive balances lasted till the end of the 1980s. The applied amount of nutrients did not reach that of taken up in a particular field until the 1960s, and has not come up to it since the 1990s either. The article discusses the need for a good nutrient supply practice, the decrease of nitrogen level in soils, the preparation of nutrient management recommendations and the bases of nitrogen fertilizer application systems.
