Abstract
The study was conducted in a stationary multivariate experiment at the experimental station of Kuban State Agrarian University during eighteen years. The technology of growing winter wheat was improved by the optimization of norms of fertilizers and plant protection systems for different levels of soil fertility. Totally there were 48 technologies for growing winter wheat after and grain: corn, sunflower, sugar beet, where studied in the experiment. The best combination of high yield (77.2 t / ha) with high quality grain (nature - 789 g / l, the total vitreousness - 60%, -14.2% protein content, gluten content - 29.0%) was found under intense technology. The grain quality meets the requirements for the 2nd class. Similar productivity (yield - 76.4 t / ha, the total vitreousness - 55% protein content - 13.4% gluten content - 27.2%) was obtained in and when grown for its resource-saving technology also. All kinds of technologies for growing winter wheat studied in the experiment were profitable, but resource-saving technology was the most efficient. Net income per hectare under this technology was 31,745 rubles, and a cost of 1 quintal of grain - 284 rubles
