Response of field agrosystems productivity to changed conditions in the Czech Republic after 1989

Original language description

There was a great change in the state economic support and consequently in the inputs level (fertilizers and pesticides consumption) for agriculture after 1989 in the Czech Republic. In the same time, market conditions changed and therefore farmers changed the management (crop structure, omitting regular crop rotation etc.). These factors have caused the reduction of agrosystems homeostasis and increased their sensitivity to weather extremes. The paper investigates the changes in productivity of field crops as a measurable indicator of agrosystem performance and its sensitivity to external conditions. An example of main crops (wheat, barley, maize and oilseed rape) in the Czech Republic was used. The official data of the Czech Statistical Office and standard statistical methods were used for analyses. After about 9 years influence of new conditions (1992-2000), the inter-annual variability in crop yields started to increase. In wheat, barley and rape, increased yield variability in the
