The possible effects of climate change on the agricultural sector
(Dr. Zsolt Harnos, Dr. István Láng)
European agriculture will face various challenges in the next couple of years, and climate change will further increase difficulties. Average global temperature has increased by 0.76 °C since 1850. Global warming is estimated at 1.8-4 °C by year 2100 compared to 1990 under the conditions of the current economic development. In the past few decades, climate change had a massive effect on rainfall volume, flora and fauna, as well as on food supply. Investigators drew the conclusion from various trials that the limit of the production area for wheat, barley, rye and maize would move by 100-150 km to the north due to climate change, and the volume of the produced crop might increase. At the same time they also stated that climate change would be accompanied by more frequent and more intensive climatic anomalies (e.g. more hot days, drought risk, wind-storms , etc.). Damages caused by extreme meteorological events considerably increase. The plans of the European Union in connection with agriculture and rural development and regarding climate change are outlined at the end of the article.


(Dr. Márta Birkás)
The first article of the column “Focusing on soil cultivation” tells its timeliness and background, and also lets you know the topics of the articles published under this heading.

The safety of structure- and moisture-conservation soil cultivation in droughty seasons
(Dr. Márta Birkás)
First the author gives an account of the conclusions of the past droughty year, and then identifies eight factors of moisture-conservation tillage: 1) Being aware of soil conditions (risk); 2) Lack of hardpan (safety); 3) Soil loosening, 4) Creation of small surface for water loss; 4) Soil cover, 5) Conservation of organic matter, 6) Stubble management; 7) Levelling after ploughing; 8 ) Less clod and dust formation. The author continues with listing mistakes increasing water loss, such as deep or delayed stubble management, unlevelled summer tillage and deficient weed control. Finally, she outlines the techniques of justified and adaptable soil management.

Agronomic and technical solutions of mechanisation adjusted to climate change
(Dr. István J. Jóri)
Comprehensive studies are conducted in order to eliminate climatic and crop management problems, towards applying environmentally friendly tillage and planting techniques. The author gives an account of the results of developing basic tillage with and without turning, seedbed preparation and mulching. She summarises in four points the response of mechanisation to the challenges of climate change. It is a future task to work out such items as changing crop management programme, merging/omitting certain operations, quicker, using more flexible and efficient machinery, and streamling mechanisation.

Tillage for and sowing of green-manure crops improving soil conditions in an extreme season
(Dr. Csaba Gyuricza)
The extreme weather conditions prevailing this year recall the attention to the use of moisture-saving crop management programmes, not only for conventional crops but also for green-manure plants (legume and non-legume crops) improving soil conditions. Hungarian growers prefer, in particular mustard, oil radish and facelia whose success is primarily determined by the used soil management programme and sowing time. The article lets us know the requirements applying an appropriate crop management programme and the best time for sowing.

Crop production in terms of conserving soil moisture
(Gergely Szöllősi)
The author and his colleagues studied the water demand of four field crops during the growing season, expressing it in dynamic water demand. They represented the values of dynamic water demand broken down for the growing season of the particular plants. Based on these data, they worked out tillage techniques that suit better to the water needs of plants and to rainfall conditions.

Tillage tricks for reducing pass number and conserving soil moisture in a family farm Report
(Attila Kosztolányi)
Bize is a small village belonging to the municipality of Marcali and close to the southern shore of Lake Balaton. We asked János Rádics, the head of a family farm there, about the reduced number of tillage passes they apply and its mechanisation background.

(Attila Kosztolányi)
The correspondent of Agrofórum asked Róbert Kőrösi, head of crop management and mechanisation in Tedej Farming and Servicing Co. about the practical aspects of moisture conserving tillage and their several years’ experience obtained in this field.


When shall we drill wheat? – Pros and cons!
(Dr. István Mihály Petróczi)
To sow wheat at its optimal time is decisive in the success of growing. The author studies the best timing for this in Hungary in the light of the research and practical results of the past decades. Considering the data, it is concluded that there is no “perfect recipe” for sowing date. At the same time, the differences among the yields reached with the particular sowing times come up to, sometimes exceed 1 t/ha. The author continues with seeking the answer to the question of the alternatives for stabilising positive or mitigating negative effects of sowing time. The Hungarian “Laloux-method” or “Szekszárd-Dalmand” model (early sowing date), completed with applying techniques of moisture conservation tillage, balanced nutrient supply and autumn programme for pest management may help in solving this problem.

The possible causes of certain virus diseases in cereals and their management options
(Ms. B. Halvaksz)

Seed potato production in Hungary
(Dénes Keresztes)
The specialist of the Agricultural Office of County Hajdú-Bihar gives a comprehensive overview of seed potato propagation in Hungary. He shows tabulated data on seed potato growing of the past 14 years, reflecting a conspicuous decrease. A considerable decline can be observed since Hungary’s EU accession involving the introduction of strict community rules in the qualification scheme of seed potato production. The decrease has further gone on, therefore the total area declared for seed potato production is only 355 hectares. After presenting the share of the leading varieties in commercial growing of seed potatoes and the expected trends in this field, the author summarises the conclusions of crop production and plant protection in the past year and the current season.

Quality targets can be reached by growing the properly selected hybrids
(Dr. Zsuzsanna Hegyi, Tamás Spitkó, István Pók, Dr. Csaba L. Marton)
The reproduction of hybrids, having been included in the national list since the 1950s, began at Martonvásár in 2001. As a result of this work, 13 old hybrids released from the research institute were compared with 11 new hybrids in 2006. The objective of the experiments launched in 2006 was to study the chemical composition of the hybrids. The investigators of the Agricultural Research Institute of the Hungarian Academy of Sciences publish the main results here in the article.

New expectations for maize quality
(Dr. Csaba L. Marton, Dr. Zsuzsanna Hegyi, Dr. Emese Nagy, Dr. János Pintér, Ferenc Rácz)
In addition to productivity and consistent yields year by year, new requirements have gained priority in maize growing in the recent times compared to the previous years. In case of maize offered for intervention buy-up, the standards for hectolitre weigh and the share of broken seeds, as well as for seed moisture have become stricter. Nowadays there are rather few words about milling industry, while the output of about 40 % grits can be increased to even 60 % by growing appropriate varieties and applying a good crop management programme. Grit output is mainly determined by specific seed weight. The experts presents the results of hybrids bread at Martonvásár in two parameters, i.e. hectolitre weight and specific weight.
