In 2021, a field experiment was conducted with white mustard (Sinapis alba L.) the seed of which is an interesting raw material in agriculture, industry and food production. Stands of tested plants were established without tillage into a freezing catch crop from the Fabaceae family within regenerative agriculture. The stand of clovers was used as a tool of bio-drilling to work the soil and as a source of nitrogen required by the subsequent crop, and the frozen biomass was applied as mulch onto the soil surface. Th...

The aim of the study was to compare variable rate (VRA) and uniform (UNI) application of mineral nitrogen fertilizers in winter wheat and to evaluate the effect on the achieved yields, nitrogen balance and nitrogen use efficiency (NUE). For these purposes, a field experiment with an area of 16.98 ha of winter wheat was established in 2022 at farm Agra Risuty s.r.o. (Czech Republic, EU). Variable nitrogen topdressing was realized twice during the vegetation period based on yield potential (YP) maps. The evaluation ...
