Abstract
It is given the impact of direct sowing technologies with different levels of intensity of arable land use, in comparison with the traditional tillage, on the elements of fertility of ordinary chernozem and productivity of spring durum wheat in the middle Volga region. The complex application of direct sowing technology using straw as fertilizer stabilizes with traditional technology the supply of soil with nitrogen, increases the content of mobile forms of phosphorus in it by 1.5-21.2%, potassium exchange – by 10.4-18.3%. Improving the nitrogen regime of the soil in direct sowing, in which the starting doses of nitrogen fertilizers were combined with integrated plant protection, provided the highest grain yield – 1.76-1.79 t/ha, which is 0.41-0.44 t/ha (30.4-32.6 %) higher than the control. The increase in yield from the use of biological products was 0.15 t / ha (11.9 %), nitrogen fertilizers N30 – 0.17 t/ha (13.4 %), the combined use of fertilizers and insecticides 0.50-0.53 t/ha (39.7-42.0 %). The highest cost recovery was after direct sowing with a maximum level of intensification-1.98-2.02 rubles/ha, which is 0.14-0.32 rubles/ha higher than the other options. The smallest economic indicators obtained in the control to 1.54 rubles/ha. According to the results of research with direct seeding of spring durum wheat in the region is proposed on the background of integrated plant protection application of calculated doses of mineral fertilizers on yield of 2.0 t/ha (pre-sowing, local-band application).
