SUSTAINABLE RYE PRODUCTION IN THE WESTSIK CROP ROTATION EXPERIMENT

Abstract

The best-known and most remarkable example of continuous production in Hungary is the Westsik crop rotation experiment established in 1929. It is still in use to study the effects of organic manure treatment, to develop models and to predict the likely effects of different cropping systems on soil properties and crop yields. In this respect, the Westsik crop rotation experiment provides data of immediate value to farmers concerning the application of green manure, straw and farmyard manure. The increased demand for food and changes in the ecological requirements of agricultural production have urged scientists to revise the widely used traditional principles and to develop alternative crop production practices. In this respect, they must strive for the adoption of technologies which serve for the simultaneous maintenance of production levels, soil fertility and environmental goals. The Westsik crop rotation experiment provides useful help and a thorough scientific basis for the solution of this problem. It models various possible methods of nutrient management and assists in answering questions on the sustainability of agricultural production. Since 1929, only minor changes have been introduced in some treatments. These changes have made the classical experiment more relevant to current research needs and farming practices.
