The paper summarizes the 5-year experimental data of the authors on the study of various technologies for sunflower cultivation in the soil and climatic conditions of the Republic of Tatarstan. Particular attention is paid to improving the methods of rational use of modern technological means with regards to the biological characteristics of the studied culture. It has been established that the classical technology of sunflower cultivation with deepening of the arable layer, diagonal closing of moisture, presowing cultivation to the depth of 6-8 cm, placement of rows in the South-North direction pre- and post- sowing harrowing and inter-row cultivation provides 93 % of the planned yield. The profitability of oilseed production is 69.2 %, and net profit is 13.7 thousand rubles per hectare. 7.4 thousand rubles of proceedings in cash comes to an enterprise from the sale of 1 ton of grown products. In large holding agricultural entities of Tatarstan with sunflower areas of more than 250-300 hectares, weed control using the Clearfield system excludes harrowing of crops and inter-row cultivation. The use of selective herbicide intended only for a single hybrid allows the 70 to 100 % weeds destruction without damaging the main crop. The economic indicators of the mixture of the developed agricultural technology with chemical crops weeding are quite high. Specifically, the profitability is 59.6 % and the cost of production of 1 ton of oilseeds is lower than its sales price by 6.7 thousand rubles.
