Selection and evaluation of winter wheat varieties for organic and conventional farming
Nedvěd, Miloš ; Capouchová, Ivana (advisor) ; Faměra, Oldřich (referee)
In the Czech Republic, wheat is the most significant field crop of both conventional and ecological cultivation. In the common conventional system, the vast variety of different crops allow cultivators to choose from all kinds of crops that are most suitable for specific floricultural conditions of their farms, and also for specific kinds of wheat use. Because of the inaccessibility of crops cultivated for conditions of ecological cultivation, ecological farmers are forced to grow crops, which are cultivated and tested to grow in conditions of conventional farming. The number of crop species is wide-ranging so there are a lot of crops the ecological farmers are not even aware of. To clarify, ecological farmers do not have the knowledge to plant such crops in the conditions of ecological farming. Nonetheless, there are some results of long-term crop experiments available that could help ecological farmers. The experiments are done by the Research Station of Department of Crop Production FAFNR CZU in Prague-Uhrinevsi. The primary research aim is to assess both production and qualitative specifications of ecological crops, and moreover, to compare the evaluation of ecological system to the conventional one. The research results allow us to define crops, which comply with both conventional and ecological type of farming.
My Bachelor thesis is a part of this research. In most cases, the same crops have reached the highest profits and quality in both the conventional and the ecological system. Based on our results, if an ecological or conventional farmer wants to primarily focus on production, then the following crops are recommended: Tobak (B), Gordian (B), and Vanessa (C). In the case of preference of food processing quality, it is recommended to use the crop Evina (E), which has reached both an exceptional quality and high profits in the ecological and the conventional system as well. Moreover, the crop Gordian (B) has achieved good quality parameters in both systems and the Gordian belonged to the profitable ones at the same time. Besides those, for example crops Annie (E) and Cimrmanova rana (E) have also reached high quality but lower profits in both systems.
