Pěstování meziplodin a jejich využití při zakládání porostů kukuřice

This thesis focuses on the cultivation of catch crops, evaluation catch crops ability of coverage of soil surface and dry matter yields of selected species catch crops and their use in the grain maize sowing. The literature review describes the different functions of catch crops in relation to the soil and the environment. In detail are discussed biotic and abiotic factors affecting the cultivation of catch crops and agronomic practices applied in their cultivation. In the thesis are discussed the economic costs associated with the cultivation of catch crops and the possibility of the use of subsidies for its cultivation. Described is also the division of catch crops by date of sowing and the definition of appropriate and inappropriate catch crops, for the individual production area in the Czech republic. The folloving section of the thesis deals with the evaluation of experiments conducted on the experimental field station in Žabčice. Experiments with catch crops were found out in 2006. There were ten catch crops: Sinapis alba L., Raphanus sativus L. var. oleiformis Pers., Phacelia tanacetifolia Benth., Fagopyrum vulgare Hill., Secale cereale L. var. multicaule Metzg. ex Alef., Panicum miliaceum L., Crambe abyssinica L. Hochst., Malva verticillata L., Phalaris canariensis L., Carthamus tictorius L. The thesis follows results from 2011 to 2014. There was catch crops ability of coverage of soil surface using digital image analysis evaluated. Further the dry matter yields of catch crops was evaluated and dry matter yields between autumn and spring sampling were compared. Field experiment was established at experimental field station in Žabčice in the years 2012/2013. The experiment was made to assess the yield of grain maize under different variants of soil tillage (direct seeding, loosening, strip tillage) in system, where Phacelia tanacetifolia was used as catch crop in comparison with soil tillage systems without Phacelia tanacetifolia (ploughing, loosening and strip tillage)
