A methodology of the formation of spring wheat cultivation technology is presented under the optimization of such factors as fertilizers and irrigation. The methodology includes the agroecological verification of spring wheat varieties, adaptation to the imitation model of grain crops, performing a series of numerical experiments, development and solution of the optimization problem of technology resource supply and determination of the optimum operating mode of irrigation. The optimum irrigation regime was based on the use of variations of the imitation model of spring wheat. This version of the model is adapted to the appropriate doses of fertilizers. An irrigation regime conducive to obtaining the required yield was formed as a result of the analysis of the curves of the water status of sowing and infiltration effluent. Consideration of the actual results obtained with the use of optimum irrigation regimes in different years of research contributed to the formulation of the rules for watering purpose. The optimum combination of regulated factors allows to improve significantly grain quality, protein up to 17.0 % and gluten up to 41.5 % content.
