AbstractThe aim of this study was to compare the effects of cowpea green manure and inorganic nitrogen (N) fertilizers on yields of winter wheat and soil emissions of nitrous oxide (N2O). The comparisons included cowpea grown solely as green manure where all biomass was terminated at maturity by tillage, summer fallow treatments with 90 kg N ha−1 as urea (90-N), and no fertilization (control) at planting of winter wheat. Fluxes of N2O were measured by closed chamber methods after soil incorporation of cowpea in autumn (October–November) and harvesting of winter wheat in summer (June–August). Growth and yields of winter wheat and N concentrations in grain and straw were also measured. Cowpea produced 9.5 Mg ha−1 shoot biomass with 253 kg N ha−1 at termination. Although soil moisture was favorable for denitrification after soil incorporation of cowpea biomass, low concentrations of soil mineral N restricted emissions of N2O from cowpea treatment. However, increased concentrations of soil mineral N and large rainfall-induced emissions were recorded from the cowpea treatment during summer. Growth of winter wheat, yield, and grain N concentrations were lowest in response to cowpea treatment and highest in 90-N treatment. In conclusion, late terminated cowpea may reduce yield of winter wheat and increase emissions of N2O outside of wheat growing seasons due to poor synchronization of N mineralization from cowpea biomass with N-demand of winter wheat.

Abstract Winter wheat is widely planted in China. The changes of winter wheat yield and quality are related to the food security of human society. Climate change has an important impact on the yield and quality of winter wheat. Diurnal temperature range (DTR) is an important factor affecting the yield and protein content of winter wheat. Furthermore, climate model is one of the main sources of error in crop model simulations of yields. Therefore, how to improve the accuracy of climate data has become an important concern for scholars.Previous model evaluations for the entire country or region cannot answer which model is suitable for the estimation of future winter wheat yield. Therefore, we evaluated the ability of climate models to simulate DTR within the range of winter wheat growing regions in China to identify the most suitable climate models for winter wheat yield and quality projections. The results show that CMIP6 models can basically reproduce the DTR of winter wheat-growing regions in China, but there are discrepancies in the simulations between nationwide and winter wheat-growing regions. EC-Earth3-Veg has the best simulation of climate DTR for wheat-growing regions (TS=0.848) and nationwide (TS=0.842), and ACCESS-CM2 has the strongest ability to simulate the annual growing season DTR (TS=0.46). In summary, in the estimation of future winter wheat yield, attention should be given to the selection of models suitable for the actual growing regions and the growing seasons of winter wheat.

Целью исследований являлось совершенствование элементов технологии возделывания озимой пшеницы в лесостепи Среднего Поволжья, позволяющих оптимизировать условия роста и развития. Исследованиями установлено, что средняя урожайность озимой пшеницы по предшественнику сидеральный пар находилась на уровне 3,19 т/га, что на 0,1 т меньше, по сравнению с черным паром. Совместная обработка семян и вегетирующих растений гуминовым удобрением Гумостим достоверно приводила к увеличению урожайности озимой пшеницы на 0,46 т/га. Наибольший уровень рентабельности (42,18 %) был отмечен в варианте с обработкой семян и вегетирующих растений гуминовым удобрением Гумостим по предшественнику черный пар. The research aimed to improve the elements of the technology for the cultivation of winter wheat in the forest-steppe of the Middle Volga region, allowing to optimize the conditions for growth and development. The studies have established that the average yield of winter wheat with green manure fallow as a forecrop was at 3.19 t/ha, which was 0.1 t less compared with black fallow. Joint treatment of seeds and vegetative plants with humic fertilizer Gumostim significantly led to an increase in winter wheat yield by 0.46 t/ ha. The highest level of profitability (42.18%) was noted in the variant with the treatment of seeds and vegetative plants with humic fertilizer Gumostim after black fallow as the forecrop.
