Yield and soil loss on no tillage – Croatian Experience

To determine the optimal ploughing depth and to make tillage simpler and less costly, taking into account edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2011) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. This paper presents the results relating to yields of maize (Zea mays L.), soybean (Glycine max L.), oilseed rape (Brassica napus L.), winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). Investigation results point to the conclusion that high density crops (winter wheat, spring barley and oilseed rape) are suitable for growing under reduced tillage systems. Yields of low density spring crops (maize and soybean) obtained under the no-tillage system are not satisfactory, especially in climatically extreme years. With respect to the trend of applying reduced tillage treatments in our agriculture, and considering the complexity of this problem, for application of a new soil tillage technology, further detailed, long-term and complex multidisciplinary research work is necessary and it should include researchers from all fields related to these problems.
