Impact of weather conditions on grain productivity and production costs under different levels of production intensification under the conditions of steppe zones of South Urals
As result of investigations the authors have established close correlative connection between yielding capacity of spring wheat and weather conditions; among them are annual rainfalls and vegetation period, as well as total effective temperature. This has been evidenced by the control variant especially under the second and third crops in rotation after fallow. The interdependence between production costs and productivity in all the predecessors as well as positive influence of plant protection from weeds is shown.
