The article contains results of field experiments (based on measuring 2 upper leaves area) on spring durum wheat varieties, which were seeded according to different expedients of basic tillage under the conditions of Orenburg Cis-Urals. It was noticed that the explored factors are highly interrelated with quantity and weight of grains in the main spike, and there was also variety reaction based on 2 upper leaves area depending on expedients of basic tillage. Also direct dependence of accumulation of solid by plants of spring-sown soft field from the area of 2 top leaves in phases of a kushcheniye, an exit in a tube and full ripeness is established. The optimality of the sizes of a sheet surface is defined from weather factors. Formation of the area of 2 top leaves of spring-sown firm field in the conditions of the Orenburg Cis-Urals characterizes reaction of culture to degree of usefulness of weather conditions of the period of vegetation and agrotechnical factors, in particular, to methods of the main processing of the soil. Proceeding from results of a research, we find possible application in selection practice of droughty zones evaluating grades on the basis of the area of leaves of two top tiers as indicator of potential efficiency.
