Effects of Nitrogen Fertilization on Seed-setting Characteristics of Spike and Grain Yield in Winter Wheat under Waterlogging at Booting Stage

Sound irrigation and nitrogen management strategies are necessary to achieve sustainable yield and water use efficiency of winter wheat in the North China Plain (NCP). The coupled effects of irrigation scheduling and the nitrogen application mode (NAM) on winter wheat growth, yield and water use efficiency under drip irrigation were evaluated with a two-year field experiment, which consisted of three irrigation scheduling levels (ISLs) (irrigating when soil water consumption (SWC) reached 20, 35 and 50 mm, referred as I20, I35 and I50, respectively) and three nitrogen application modes (NAMs) (ratio of basal application and topdressing as 50:50, 25:75 and 0:100, referred as N50:50, N25:75 and N0:100, respectively). The experimental results showed that irrigating winter wheat at ISL I35 substantially (p < 0.05) improved the grain yield by 15.89%, 3.32% and 14.82%, 4.31% and water use efficiency (WUE) by 5.23%, 16.03% and 5.26%, 12.36%, compared with those at ISL I20 and I50 in 2017–2018 and 2018–2019 growing seasons, respectively. NAM N25:75 appeared very beneficial in terms of grain yield, yield components and WUE as compared to other NAM levels. The maximum grain yield (8.62 and 9.40 t ha−1) and water use efficiency (1.88 and 2.09 kg m−3) were achieved in treatment I35N25:75 in two growing seasons over those in other treatments. The results in this study may deliver a scientific basis for irrigation and nitrogen fertilization management of the drip-irrigated winter wheat production in the NCP.

Nitric Oxide Emissions

Abstract An effective way to reduce nitric oxide emissions may be to reduce the level of nitrogen fertilization. Specialized formulations such as biostimulators are a good alternative to conventional mineral fertilization. The aim of the study was to determine the effect of the application of biostimulation agents (Asahi SL, Kelpak SL, Tytanit) applied against the limited dose of nitrogen (75 kgN·ha−1) on winter wheat ‘Muszelka’, their effect was measured on the parameters: grain yield, protein content, amount of chlorophyll and root mass. No statistically significant changes in yields were observed, but after application of the Asahi SL and Kelpak SL, considerably higher values were found as compared to the controls. It should be emphasised that the applied formulations significantly affected the root mass and chlorophyll content of the leaves. Especially in the case of roots of the plants where the biostimulator Asahi was used in the phase BBCH 37, Kelpak in BBCH 23 and fertilizer Tytanit in BBCH 37. And in the case of chlorophyll objects, where Tytanit was applied in BBCH 37 and 69. In the study, significant correlation was found only between the chlorophyll content and the root mass (r = 0.54).

Soil Water Consumption

Abstract To evaluate soil water consumption, changes in quantity and quality of winter wheat seed and forage under different irrigation treatments, an experiment was conducted in Beijing, China, in the 2012-2013. Irrigation treatments were (I1): irrigation before sowing, (I2): irrigation before sowing + before freezing; (I3): irrigation before sowing + before freezing + irrigation in the beginning of erecting stage + irrigation at flowering stage; (I4): irrigation before sowing + irrigation before freezing + irrigation at the booting stage + irrigation at flowering stage. The laid out of experiment was randomized complete block design, repeated six times. The effect of irrigation on total biological yield, grain yield and harvest index is significant. The highest mean soil water consumption in Oct., Nov., Dec., Jan., Feb., Mar., Apr. and May was obtained for lysimeter 10 (I2), lysimeter 10 (I2), lysimeter 6 (I2), lysimeter 10 (I2), lysimeter 10 (I2), lysimeter 10 (I2), lysimeter 11 (I3), and lysimeter 10 (I2), respectively. The results from the study indicate that irrigation winter wheat throughout the booting stage and flowering stage increased grain yield, harvest index, potassium percentage, ash percentage of forage wheat at flowering stage, seed and forage protein percentage. Evapotranspiration trends increased steadily, especially in last three months, in which the lysimeter fields were covered by winter wheat completely.
