The main goal of research was to assess whether the growing of intermediate crops prone to frost kill could contribute to increase the capacity of arable land for the retention of N-substances. In 2018, a field experiment was established, in which the following intermediate crops were grown in the period between the main crops (wheat - corn): (i) Trifolium vesiculosum Savi., (ii) Trifolium pannonicum Jacq., (iii) Trifolium subterraneum L., and a control variant with no inter crop. The intermediate crops were sown ...

The leaching of mineral nitrogen (Nmin) represents a serious problem of modern agriculture in the European Union and also in the Czech Republic. The reason is the loss of nutrient important for plants from the soil environment and subsequent threat to the quality of soil ecosystem. The main goal of the present work is to show the influence of the mixed cropping system in the sowing process on Nmin leaching of from arable soil. Mixed cropping system represents cultivation of different crops at one field simultaneou...

Biogas production and its use in biogas plants presents established technology with the aim of production of renewable energy and also using organic residues with different origin. The main goal of this work was to analyse potential legume and grass crops in methane production as an alternative to corn silage. Ten different crops within individual variants were chosen as a potential source of biomass for biogas production: Medicago sativa L. (two varieties), Trifolium pannonicum L., Galega orientalis L., Lolium pe...

The main goal of the presented research was to compare the nitrogen use efficiency (NUE) of winter wheat and white clover mixed cropping system (MC) with sole cropping system of winter wheat (SC). The above goal was investigated using lysimetric experiment carried out for two vegetation periods (2012?2014). The experiment consisted of seven variants with different cropping system and level of fertilization: five variants were grown as MC (0 kg N/ha; 112 kg N/ha; 112 kg N/ha + 1.25 L of humic acids/ha; 70 kg N + 0....

This paper presents the first year of the field experiment to evaluate the possibility of growing corn (Zea mays ssp. mays) in mixed culture (MC) with selected leguminous species. The main objective was to monitor the influence of MC agrotechnology on the yield of maize, individual leguminous crops and evaluation of biological yields through using the Land Equivalent Ratio (LER) for each variant of experiment. The selected legumes plant and corn were grown separately like sole crop (SC) or in MC (legumes and plant...
