The N min contents of T3 (240 kg ha À1 ) and T4 (300 kg ha À1 ) in the soil profile (0-100 cm) were slightly higher than the value of 229 kg ha À1 (0-90 cm) found by Lu et al (2014). The amount of fertilizer N in the present study equivalent to the amount of N fertilizer recommended depending on the in-season N min test was about 87-180 kg N ha À1 (Cui et al, 2008a).…”

“…The formation of spike number is determined by the dynamics of coordinated development of stem number and individual tiller dry matter accumulation, in particular, for pre‐winter tillers (Lu et al, 2014). Pre‐winter stem number and individual tiller dry matter significantly decreased with delayed sowing date in this study (Fig.…”

“…H igh wheat yield generally results from an optimal plant population that favors the coordinated development of yield components (Xu et al, 2013; Lu et al, 2014). In practice, sowing and fertilizer regimes are considered the primary management practices regulating stand development (Bassu et al, 2009; Lu et al, 2014). Crop response to manure application is variable and could be affected by many factors, including environmental and soil conditions (Mitchell et al, 1991; Johnston, 1997).…”

“…Recent studies have proposed that increasing wheat yield cannot be dependent solely on increasing the total tiller number, but should emphasize improving early initiated tiller growth (quantity and individual stem quality) to increase tiller productive percentage (Maidl et al, 1998; Duggan et al, 2005; Lu et al, 2014). For example, Meng et al (2013) found that high‐yielding populations usually consist of more and stronger pre‐winter tillers compared with low‐yielding populations that have more spring tillers (TS).…”

“…For example, Meng et al (2013) found that high‐yielding populations usually consist of more and stronger pre‐winter tillers compared with low‐yielding populations that have more spring tillers (TS). Lu et al (2014) reported that an increased number of spring unproductive tillers resulted in lower yield for high‐tillering cultivars grown in the NCP. Nonetheless, how the pre‐winter and spring stem elongation population development in stem number and individual stem quality (dry matter accumulation) was affected by sowing date and manure application remains unclear relative to other main agronomic traits for aboveground crops such as wheat yield (Kundu et al, 2006), total tiller number and the physical, chemical, and biological properties of soil (Parham et al, 2003; Zaller and Kopke, 2004).…”

Grain yields can be limited from delayed seeding worldwide. Perhaps yield suppressions can be overcome by applying farm manure. Th e objective of this study was to determine the infl uence of manure application and sowing date on wheat (Triticum aestivum L.) yield and population development. A fi eld experiment was conducted over two seasons, with three sowing dates (early [ES]-5 October; mid [M]-10 October; late [LS]-15 October) with or without manure application (each plot receiving same chemical N, P, and K fertilizer) in the North China Plain (NCP). Comparing early to LS, delayed sowing reduced wheat yield from 9.5 to 7.8 t ha -1 . Furthermore, manure application provided a 16 and 11% yield compensation for the M and LS date treatments, respectively, but did not signifi cantly increase yield for ES. Th ese results were attributed to manure increasing the wheat pre-winter tiller numbers for the midseeding date and manure increasing the spring tiller numbers for the LS date. High tiller mortality rate of ES treatment with manure application resulted in similar spike number and wheat yield as no manure treatment. Manure application improved plant N, P, and K concentration and soil temperature at a depth of 5 cm (0.4°C for pre-winter and 0.5-0.8°C for poststem elongation), actions that may be important for improving population development.

Quantitative understanding of photosynthetic production of winter wheat (Triticum aestivum L.) under N fertilizer management is crucial for achieving sustainable high grain yield with less environmental risks. A 3‐yr study was conducted to evaluate dry matter and N accumulation for sustainable high grain yield with respect to preanthesis N management of winter wheat in the North China Plain. Optimal nitrogen application rate (Opt.N) was determined by subtracting soil nitrate measured at root layers from the target N‐demand for wheat. Other treatments included no N fertilizer control, conventional farmer N practice, and 70 and 130% of Opt.N. The highest grain yield (9 t ha−1) with high N use efficiency (NUE) was attained with Opt.N rate which is predominantly attributed to high dry matter (69%) and N accumulation (94%) from sowing to preanthesis. Most remarkably, N remobilization from preanthesis contributed nearly 97% of grain N accumulation. Highest dry matter production was achieved when the critical plant N concentration reached 2.90% at stem elongation stage and 1.91% at anthesis. The maximum leaf area index and photosynthetic rate needed for high dry matter production were realized with similar critical plant N concentration during preanthesis (2.55 and 2.36 for at GS31, respectively) and at GS64 (2.01 and 1.83%). Supplying additional N fertilizer over Opt.N increased neither grain yield nor grain N accumulation but heightened environmental risks from soil N surplus. These results highlight the importance of preanthesis N fertilizer optimization and provide effective N management strategy to enable high wheat yield with high NUE.
