A water-saving cultivation technique of supplementary irrigation based on soil moisture levels has been adopted for winter wheat production in the Huang-Huai-Hai Plain of China, due to the enhanced water-use efficiency. However, appropriate split nitrogen management may further improve crop growth and grain yield. Here, we conducted a 2-year field experiment to determine if split nitrogen management might improve wheat productivity by enhancing 13C photosynthate mobilization and the antioxidant defense system under water-saving conditions. Split nitrogen management involved a constant total nitrogen rate (240 kg ha−1) split in four different proportions between sowing and jointing stage, i.e., 10:0 (N1), 7:3 (N2), 5:5 (N3), and 3:7 (N4). The N3 treatment significantly enhanced “soil-plant analysis development” values, superoxide dismutase antioxidant activity, soluble protein content, sucrose content, and sucrose phosphate synthetase activity, although it reduced the accumulation of malondialdehyde (MDA). The N3 treatment ultimately increased the amount of dry matter assimilation after anthesis significantly. In addition, the 13C isotope tracer experiment revealed that the N3 treatment promoted the assimilation of carbohydrates after anthesis and their partitioning to the developing grains. Compared to the unequal ratio treatments (N1, N2, and N4), the equal ratio treatment (N3) increased grain yield by 5.70–16.72% via increasing 1000-grain weight and number of grains per spike in both growing seasons. Therefore, we recommend the use of a 5:5 basal-topdressing split nitrogen fertilizer application under water-saving irrigation conditions to promote antioxidant enzyme activity and the remobilization of photosynthate after anthesis for improving wheat grain yield.

“…At present, winter wheat occupies significant sown areas and, subject to cultivation tec hnologies , provides a yield of up to 8.0 t/ha. The advantage of the crop is the ability to cultivate it in regions w ith different soil and climatic conditions and a higher yield (by 15-25%) compared to spring wheat [50][51][52][53].…”

The development of the grain industry determines the food security level in Russia. Grain is a food product for humans, animal feed, raw material for industries. The research was carried out in 2018-2019 in the Samara region conditions. The research purpose is to determine the effectiveness of nitrogen fertilizing in the winter wheat cultivation. The research tasks included: - to identify the effect of nitrogen fertilization on the winter wheat yield; - to calculate the economic efficiency of using nitrogen fertilizers for winter wheat. As a result of the studies, it was found that in the variant without the use of nitrogen fertilization, the yield of winter wheat was 21.8 cwt/ha and was the lowest. In variants with the top-dressing use, the yield varied from 22.7 cwt/ha, when used as top-dressing of ammonium nitrate to 24.1 cwt/ha when used as an additional fertilizing of KASS. The increase in yield from fertilizing with nitrogen varied from 0.9 cwt/ha (4.1%) to 2.3 cwt/ha (10.6%). From an economic viewpoint, the most effective option was the application of nitrogen fertilizers KASSA, which made it possible to obtain an economic effect of 1240.95 rubles, while reducing the cost by 165.6-628 rubles/cwt and increasing the profitability level by 57.5-66.1%. The results obtained make it possible to recommend the production of the use of liquid forms of nitrogen fertilizers for feeding winter wheat, contributing to an increase in the profitability of crop cultivation.

“…Long-term use of traditional tillage as the main farming method in this area not only cause soil hardening and shallow plowing layers but also reduces soil water storage and moisture conservation capacity, resulting in adverse consequences for high and stable grain yield ( Bissett et al, 2013 ; Wang, Sun & Wang, 2018 ). The sustainable development of agriculture in the NCP is adversely affected by the destruction of soil structure, which reduces water use efficiency and crop yield ( Balwinder-Singh et al, 2011 ; Latifmanesh et al, 2018 ). Therefore, it is vital to find a reasonable land use technique that facilitates the maintenance of soil fertility and the improvement of grain yield.…”

Based on two years of field experiments, under different soil tillage methods and straw management practices, which included conventional tillage (CT), subsoiling (SS), rotary tillage (RT), and no-tillage (NT), combined with either straw return (S) or straw removal (0), we characterized the dynamic changes in Δ13C among three height layers [upper (U, 240 cm above the ground), middle (M, 120 cm above the ground), and lower (L, 30 cm above the ground)] of the summer maize canopy. The Δ13C, the factors affecting it, and the relationships between Δ13C and soil water content (SWC), the leaf area index (LAI), canopy microclimate, and the CO2 concentration were elucidated. The results indicated that the Δ13C of summer maize at the pre-filling stage was greater than that at the post-filling stage. Δ13C also varied at different heights, with the order of the Δ13C values being L > U > M. Among the different tillage methods, the Δ13C values were ordered SSS > CTS > RTS > NTS. SSS and NTS significantly increased the LAI; air temperature and relative humidity tended to gradually decrease with the increase in height of summer maize. Correlation analyses of the various influencing factors and Δ13C showed that SWC, LAI, air temperature, and CO2 concentration were all positively correlated with Δ13C, in which LAI and air temperature were significantly or extremely significantly positively correlated with Δ13C. In addition, we show that Δ13C can be used as a prediction index for summer maize yield, providing a theoretical basis for future yield research that may save precious time in summer maize breeding efforts.
