In organic production conversion period is the most difficult time for producers. To overcome that period with minimum loss of income it is very important to choose appropriate crop. In this experiment 9 producers are chosen and they start with organic production on 11 ha. After two years of production it was obvious that chamomile is excellent crop for conversion period because does not need protection from pests and disease and does not need mineral fertilizers. Yield was between 1600 and 2500 kg/ha of pure chamomile flowers and between 1500 and 2200 kg/ha flowers with petals. After drying producers put on the market chamomile like conventional but anyway they earn more than with some cereal crops. This experiment shows that chamomile is for sure suitable crop for conversion period.
