This article presents the results of studies on the effect of nutrition background on the sowing time, different precursors on the yield and economic efficiency of growing wheat-emmer grains (polba). A very significant influence is given to the study of the crop formation of the oldest food culture polba on the gray forest soil of the Kama zone of the Republic of Tatarstan. Regardless of nutrition background and the predecessor, when the crop is delayed, the productivity is reduced. When sowing for 14 days after the optimal period, the productivity on both nutrition backgrounds, regardless of the predecessor, decreased from 0.42 to 0.51 tons per hectare, against the background on a fertilized background, respectively, to 0.56 - 0.84 tons per hectare, while the profitability of production is reduced at 1 against the background of -51.4 - 61.6%, against the 2 background - 78.4 -87.1%. The main disadvantage of wheat-emmer (polba) as a grain crop is the relative low productivity. The average productivity for 2010 -2017 in the conditions of the Kama zone of the Republic of Tatarstan was 2.05 tons per hectare, the spring soft wheat was 2.15 tons, which is slightly different from the wheat productivity of emmer (polba). Taking into account the severely arid conditions during the growing season of spring wheat for the last seven years, this is a good result for wheat from an economic point of view.
