【 摘 要 】

The effects of previous crop, fertilizers and pesticides on the wheat yield and the cost efficiency of wheat production in Siberia were studied in two-year field experiment. It was found that the yield mostly depends on the previous crop and pesticides, whereas the fertilizer demonstrated relatively slight effect in the year favourable for wheat growth and no effect in the year unfavourable for wheat growth. Cost-effectiveness analysis showed that the most effective way to reduce the environmental impact of wheat production in Siberia is the use of fallow in crop rotation scheme. Usage of fallow without chemical fertilisers provides higher yield than variants with fertilisers and pesticides where wheat was used as a previous crop. Cost efficiency of variant with fallow was 20.8% what is comparable with cost efficiency of the most cost effective variants (fallow as a as a previous crop + pesticides with cost efficiency of 36.6% and wheat as a previous crop + fertilizers with cost efficiency of 30.4%).
