The position and competitiveness of the potato sector after the EU accession
(Dr. András Szentirmay)
The author analyses the problems in potato growing that have come to light since Hungary’s EU accession (e.g. the difference in average yields between the old and new member states). He believes that the difference is caused by our backwardness in crop management (mechanisation and the applied crop production techniques). It is noteworthy that in the old member countries 100% of potatoes are grown in contracted sales system, while in Hungary 59.5 % of potato production is managed without sales contracts. The new member states shall satisfy market demands, increase their competitiveness, the efficiency of the marketing system and develop crop production programmes. The operators of the sector need to make efforts in order to represent their interests the most efficiently possible in groups organised on grower, production integrator, sales or any similar bases.

Field growing of early potatoes
(Dr. József Kruppa, Dr. Sándor Hodossi, Dr. Györgyi Csontos)
The authors inform on the new market situation created after the EU accession. In their opinion Hungarian growers may have chances in Western Europe especially in early potato markets (May and June). The area of early potatoes is 6-8 thousand hectares of which 700 ha are covered with plastic foil. They believe that this system will intensively spread. They give a detailed account of the biological bases, the key points of choosing the varieties, the process of forcing and rooting seed potatoes and the benefits of sprouting seed potatoes. Furthermore, they present the elements of the crop production programme (preparation of seed potatoes, crop stand, nutrient and water supply, cultural operations), the methods to be applied in growing early potatoes (temporary plastic foil cover, early and summer growing without cover) and plant protection.

Seen, heard, read. Commemorating Haberlandt Gottlieb
(Gyula Kettinger)
On 26 November 2004 in Mosonmagyaróvár, the Agricultural and Food Science Faculty of the West-Hungarian University commemorated the founder of the plant tissue culturing, Haberlandt Gottlieb, informing on his biography and technical results. Haberlandt memorial plaquettes were handed over on the commemorating session and a wreath was laid on his statue.

Early potatoes: uses, quality requirements and recent results of improving chemical composition
(Dr. József Kruppa, Dr. Zoltán Gyõri)
The authors describe that, due to the different crop management programmes, early potatoes slightly differ in volume, crop quality and taste from potatoes harvested in autumn and stored, and their quality parameters are genetically determined. They inform on the requirements for variety candidates of the National Institute of Agricultural Quality Control. They call the attention to the priority of growing varieties included in the National List with confirmed performance under Hungarian conditions. It is followed by an account of the varieties grown for the particular uses and the requirements they are expected to satisfy. Then Readers get to know the crop appearance growers need to ensure to be able to supply supermarkets. Finally, recent research results are presented on the chemical composition of early and midseason potato varieties.

Characteristics of nutrient supply for potatoes
(Dr. Károly Pocsay)
In the author’s opinion, the difficulties of potato growing professionals may derive from their uncertainties in nutrient and manure requirements of potatoes, nutrient supply capacity of Hungarian soils and application techniques. They do not make any difference between the nutrient and organic manure requirements of the different varieties and production purposes. The author calls the attention to the fact that the timing and mode of applying organic manures are more important than the quality and proportion of the active substances. Trials on manure application were established in potatoes in order to clarify this problem the results of which can be found in the article.

Recommendations of the “potato workshop” of Keszthely for growers
(Dr. Zsolt Polgár, István Wolf)
The Hungarian potato growing area has decreased to almost the half of its original surface. The EU accession has revealed the problems of the sector (unfavourable variety choice, insufficient biological bases, high production costs and deficiencies in crop management programmes). The authors provide growers keeping on producing potatoes with technical recommendations in order to improve the position of the sector, maintain domestic market as well as to assist competitiveness and profitability. They call the attention to the importance of observing phytosanitary rules and cooperation to coordinate production and sales. They suggest variety change step by step based on mainly Hungarian resources, using the varieties produced by breeders in Keszthely.

Potatoes in Hungary: growing, distribution, consumption. Report
(Dr. Pál Békési)
Potato is the “bread of the poor”, quotes the author the saying, because anyone can obtain it, relatively cheap and nourishing, rich in starch, vitamin C and minerals. In addition to household preparation, processing industry also demands it. However, EU-accession has resulted in new economic conditions and an open market. The author asked for the opinion of six professionals about the current problems of potato growing.

Outlook to the near future of Hungarian seed potato growing
(Dr. Levente Tas)
The author describes the market disturbances and problems that can be experienced in the sales of potato for consumption and the propagation of seed potatoes. He says that seed potato imports are in the hands of well-organised professional organisations that are not interested in maintaining a profitable Hungarian seed potato growing system. The Ministerial Decree 48/2004.(IV. 21.) FVM contains the new quality requirements which mainly differ from the previous one in the issue of viruses. The paper informs on the occurrence of the major potato virus diseases in Europe and Hungary where the level of production is considerably lagging behind the average of the EU. In the author’s opinion it is mainly caused by using poor quality seed potatoes. As regards the varieties, there are no remarkable changes in their structure and the varieties resistant to important virus-diseases spread only slowly.

Have there been any changes in the chemical control of weeds in potatoes?
(Zsuzsanna Hoffmann Pathy)
The author believes that the number of herbicides authorised for use in potatoes is continuously decreasing that can be explained by the reduction of potato growing areas. This trend is characteristic of the whole country. Unfortunately growing is at an advanced level only on 20% of the total potato production area. He calls the attention to the fact that chemical weed control in the crop depends on weather conditions and the composition of the weed flora is different from those of the other crops. Finally, he informs on the herbicides authorised for use in potatoes.


How is malting barley grown in Hernádkércs?
(József Kovács)
The author gives a brief account of the elements of the barley management programme in their cooperative (preceding, stubble stripping, accurate soil preparation at due time in autumn). He shows the importance of sowing date, optimum crop density, choosing the variety, seed treatment and soil nutrient supply. Then he describes treatments to control weeds, fungal diseases and insect pests. He highlights the importance of harvesting at proper time and in good quality. He believes that the success of malting barley lies in strictly observing the crop management programme, optimal soil and rainfall conditions, balanced nutrient supply, avoiding the use of herbicides of hormonal activity and the timing of pesticide applications.

Increasing damages caused by vine chafer and green rose chafer, possibilities for their environmentally friendly control
(Dr. Erzsébet Voigt, Dr. Miklós Tóth, Dr. Zoltán Imrei, József Vuts, László Szöllõs, Dr. István Szarukán)
The authors reveal the plant protection problems arising from the changes of the ecological conditions taken place in the past few years. Coleoptera species, that caused insignificant losses earlier, provoked severe damages in crop quality and quantity in the drier and warmer years. Among chafers, vine chafer (Anomala vitis), Anomala dubia and green rose chafer (Cetonia aurata) were recorded for their increased injuries. The paper presents the morphology, geographical distribution, damages, host ranges and forecasting possibilities of the particular species. It furthermore offers environmentally friendly methods for the control of vine chafer and green rose chafer.

Economic effects of agricultural mechanisation (3)
(Dr. István Husti)
Since the spreading of mechanisation, the importance of time management has increased as machines and equipments are of great value. Their breakdown, falling out of production has adverse economic consequences. The utilization in time of the agricultural power machines and implements can be divided into three categories. The author discusses the details of these three fields (utilization in the whole calendar year, utilization during the high season and utilization in the daily work). He analyses the economic effects of time management.

Overview of pests and diseases in 2004 (3)
Miklós Tóth, Sándor Kobza, Gábor Szalkai)
In 2004 the authors analysed pests and diseases affecting vegetable crops in the light of climatic conditions. Among pepper diseases, bacterial spot (Xanthomonas) incidence was conspicuous, while damages caused by viruses reached 20-40 %. In tomatoes, ecological conditions were conducive to late blight (Phytophthora infestans) while they were adverse for early blight (Alternaria solani) and Septoria leaf spot. Leaf mould (Cladosporium fulvum) and white mould (Sclerotinia sclerotiorum) caused medium level of infection. Cotton bollworm larvae moderately attacked both crops. In cucumbers downy mildew, bacteria, powdery mildew, while in water melon Fusarium wilt caused problems.

Note for growers. About professional skills
(Miklós Kurucz)
On the occasion of the Agricultural Book-month, several valuable thoughts were put into words by the author. He raises the question: can the lack of professional knowledge lead to the so frequent failure in production? The number of well-prepared professionals in the sector is rather low, though there are various “tools” to assist work: training courses, manuals and internet. Our ancestors also used the winter break for attending “gold” and “silver courses” for farmers, and for training each other.
