Thoughts about tillage in spring
(Dr. Tamás Kismányoki)
The author gives advice for performing soil preparation in spring at a due time and in good quality for preserving winter precipitation and forming proper seedbed. He informs on the reasonable use of the particular tillage implements and on soil cultivation in spring for partially replacing autumn ploughing if omitted. Furthermore he outlines the key points of biological and economical tillage.

Experiences and recommendations in the nutrient supply for maize
(Dr. Katalin Debreczeni)
In the author’s opinion many people believe that they have to completely give up fertilizer use if they wish to follow the principles of sustainable agriculture. Nutrient management serves for harmonising nutrient demand of plants and nutrient supply of soils. The agro-ecological potential of a production site is determined by soil, natural water regime and climatic conditions. The article informs on the type and quantity of the particular nutrient elements and water maize requires at the different growth stages to produce optimum crop yields.

Nutrient supply for maize in calcareous chernozem soil
(Dr. János Nagy, Dr. Attila Megyes)
The authors give an account of the decisive role of maize in global and Hungarian agriculture. They point out that the big fluctuations in the last decade’s yields were caused by the improper crop management programmes and weather extremities. They believe that there is no successful farming without a sound soil-life of appropriate nutrient level. A key element of maize production is balanced nutrient supply. Growers need to plan it tailored to the soil type and the production site, based on soil analysis. The results of the multifactor long-term trials established at the Experimental Station of the Agricultural Centre of the Debrecen University help better understanding the relationship of plants and the environment. In addition to its role in crop production, nutrient supply based on the long-term trials serve also for environmental protection and ensures sustainable development.

Key in the hand, money in the pocket (x)
(István Tamás)
Hungarian Kwizda offers its programme titled “supplying nutrients and protecting plants” for growers in order to achieve profitable production.

Agricultural use of soil micro-organisms
(Dr. János Szabó Szűcs)
The author deals with the effect of soil bacteria and soil microbial preparations on increasing crop quality and quantity. Soil microbes do not impose risks to the environment or the treated soil and plants. The development in microbiology and biotechnology has allowed thoroughly studying the genome, mode of action and metabolites of microbes, as well as manufacturing certain preparations of different effects. Their application reduces environmental load, increases health and resistance of plants and positively influences the structure and water regime of the soil.

Summarising weed control in sunflowers
(Dr Gabriella Benécs Bárdi)
The author analyses the possibilities, importance and problems of sunflower growing after the EU accession. She discusses the importance of weed control methods, the possibilities and importance of cultural control and the role of factors influencing the selection of herbicides (soil quality, weather conditions, etc.). Based on the experience obtained in dry and rainy years, she gives detailed advice and options for the particular weed control programmes (ppi, pre-post, pre-emergence, post-emergence). She gives an account of the pros and eventual contras of using herbicide resistant sunflower hybrids. Finally, she gives a tabulated summary of the herbicides registered for use in sunflowers.

Dangerous twelve (IV/12) Horsetails
(László Szentey)
The author describes the botanical characteristics of Equisetaceae family, followed by the detailed morphology of the species present in the Hungarian flora: field horsetail (Equsetum arvense), giant horsetail (E. telmateia), marsh horsetail (E. palustre) and E. ramosissimum. He informs on their biology, geographical distribution, damages and the possibilities of their control in various field crops.

Wash-off spraying long ago and now
(Ágoston Tóth)
Wash-off spraying in autumn comes more and more into use in the protection of orchards and vineyards. The author discusses the plant protection problems that justify applying this technique. He calls the attention to the fact that this treatment does not replace, only completes the “classical” wash-off spraying in spring, improving its efficacy. Furthermore, he gives a detailed account of timing the treatments in autumn and spring adjusted to the particular growth stages of the crop, the mode of action of the products, their effect on the different pests and diseases, the mode of application, as well as of the registered active substances and products.

He offers readers a proposal for efficient control of the disease based on trial results.

Timely control of rape pests in spring
(Dr. Kálmán Szeőke)
The author outlines the rape pests and their control at the particular growth stages of the crop. He draws the attention to the likelihood of increased field vole populations in autumn, to the possibilities and performing biological and chemical control. He discusses the biology, damages and registered chemicals for the control of the major rape pests. He recommends determining the time of chemical treatments based on forecasting in each field. Only this method can ensure successful control. Furthermore, he calls the attention to the effect of ecological factors influencing the biology of the pests.
