Czech Republic is one of the world's leading producers of the poppy seeds. Concerning the growing field area of poppy, the Czech Republic is lead producer of the poppy seeds at the international level (Vašák, 2010; Cihlář, 2012).
Poppy seed is very sensitive on many internal and external factors during cultivation, especially in the beginning of germination and emergence. At present, there are not registered preparations available for seed dressing for poppy seed in the Czech Republic (Prokinová, 2006). However, there has been done many experiments based on testing of natural substances (eg. humates and plant extracts), microorganisms and especially the application of soil fungi in seed treatment recently
The aim of this study is to evaluate the effect of selected regional varieties of poppy cultivation and seed treatment to yield parameters of poppy seed both individually and in combination,. For the thesis was essential to describe the suitability of varieties for growing in organic and integrated agriculture in relation to the efficiency of production. Evaluation of the seed quality of the varieties was carried out in the field as well as under laboratory conditions. Before sowing, seeds were treated by preparations Gliorex and TS Osivo, untreated variant has been used as a control.
During plant cultivation were monitored shape of the plants, the degree of infestation, weed control and other treatments based on natural substances. Neem-Azal was used as the pest regulator. The second variant was treated by foliar application of TS Květa.
Seeds harvested from variants of our trial were tested under laboratory conditions for comparison of differences between varieties. The tests also revealed the seed infestation and what percentage of the seed is viable. The last evaluation was carried out on the basis of the weight of thousands of seeds (HTS), which reflects the yield determined by the selected seed treatment.
