It seems that the future will also be prospective for the crop. However, time to time it is not in vain to recall the past, reviewing the history of the spread of maize in the world and our country.

Present day maize growing
(Zsuzsa Molnár)
The author from the Agricultural Economics Research Institute lets us have an insight into the global situation of yields, exports and imports in 2009.

Extracts from the results of maize growing
(Compiled by: Dr. Tamás Árendás)
Maize growers requiring reliable information may read the third year’ results of post-registration trials with varieties. The aim of the experiments is that, based on correct data and being aware of objective results, growers may select among the varieties capable of reaching acceptable yields and known quality. The article gives tabulated information on the particular varieties by average performance and detailed for the experimental sites for three maturity groups.

Relationships of rainfall, preceding and maize
(Dr. Tamás Árendás, Dr. Péter Bónis, Dr. Dénes Molnár, Dr. Zoltán Berzsenyi)
The Agricultural Research Institute of the Hungarian Academy of Sciences carried out long-term trials of several decades, studying the effect of the preceding and differences in rainfall in addition to the response to the particular fertilizer applications. The authors draw maize growers’ attention to the decision criteria and options to allow, before sowing, the mitigation of the adverse effects of unforeseen weather extremities.

The effect of nutrient supply on maize quality
(Dr. Zoltán Izsáki)
The protein and oil content of maize, as well as its amino acid and oleic acid composition are characteristics basically genetically determined, but ecological and agronomic factors may also modify them. Among the latter factors, the role of nutrient supply is the most characteristic in influencing crop quality. Based on the results of the long-term trials carried out in 1997-2004 at Szarvas, the authors wish to present the effect of nutrient supply on quality and to provide information about the farm practice of fertilizer application.

The conclusions of long-term weed control trials in Martonvásár
(Dr. Péter Bónis et al.)
The authors from the Agricultural Research Institute of the Hungarian Academy of Sciences summarise the experience obtained in the several-decades’ long-term trials of weed control in maize, seeking the answers to two questions. Firstly, about the long-term effect of herbicides registered for use in maize and the way they influence the change of weed composition and the selection of weed species, eventually the building-up of resistance. Secondly, about the impact of annual tillage operation on the abundance relations of weed infestation and the effect of herbicides.
