ON STRENGTH CALCULATION OF THIN-WALLED SHELLS

The article describes some approaches to a reduce of production costs of agricultural producers.The main sources of information were: the results of experimental investigations, carried off in Verkhnevolzhsky Federal Agrarian Research Centre (Russia) in the field crop rotation; production and finance documentation of "Rassvet" APC (Ivanovo region) and "Suvorovskoe" JSC (Vladimir region); photochronographic observations, conducted at some agricultural organizations.In the work the follow methods were used: system and situate approaches, methods of comparative analysis, analysis of breakeven, method of net cost calculation "Direct -costing".The main approaches are: the use of scale effect and production diversification; choice of rational agricultural system, production intensification level, system of machines, fertilizer so on; choice of cheaper materials, selection of the less expensive technological operations and them combinations based on situational approach, in particular, taking into account weather conditions.As well as the matter of efficiency of input costs for crops cultivation is described.
