Conditions for increasing yields and improving economics of winter oilseed rape

Intensification of oilseed rape yields must be substantially more responsive to changes in natural conditions. In warming, growth of CO2 content, aridisation of environment. The specific way is to use winter cryptovegetation for winter oilseed rape fertilization, increasing stand density. It is mentioned forecast of crop production in the Czech Republic and especially mentioned the development of milk production. In tables, graphs and maps are given trends of seeds yields, plowing of oilseed rape, condition of rape before winter in autumn 2012 to 2014, late harvest impact on yields of rapeseed and oilseed rape response to nitrogen fertilization in late October.
