“…Maintaining adequate N levels is important since many of the newer high‐yielding cultivars commonly have lower GPC, requiring careful N management to meet grain quality standards. Post‐pollination (three‐split) N treatment gave the highest grain protein concentration in three out of five environments and was in agreement with previous studies (Bly and Woodard, 2003; Woolfolk et al, 2002).…”

“…Foliar application of N has often been used as a way to increase nitrogen use efficiency (NUE) and GPC in wheat. Bly and Woodard (2003) found post‐pollination foliar N applications increased grain protein, especially when the planned yield goal was exceeded. Schatz et al (1991) showed that postanthesis application of N increased grain protein by 0.95% points at 33.6 kg ha −1 of urea ammonium nitrate (UAN).…”

Seeding Rate and Nitrogen Management Effects on Spring Wheat Yield and Yield Components

Seeding rate, N level, and N application timing are key management factors for spring wheat (Triticum aestivum L.) production in North Dakota. Experiments were conducted under dryland (Casselton, ND) and irrigated (Carrington, ND) conditions in 2003 to 2005 to determine the optimum combination of seeding rate and N management to maximize yield of hard red spring wheat (HRSW). Treatments consisted of a factorial combination of HRSW genotypes ('Briggs', 'Alsen', 'Granite', and ND 740), seeding rates (2.9 and 4.2 million seeds ha 21 ), N levels (140 and 224 kg ha 21 for the dryland site; 168 and 280 kg ha 21 for the irrigated site), and N application timing (preplant, two-split, and three-split). Nitrogen level, N timing, and seeding rate showed no significant effect on grain yield across environments. However, genotype significantly influenced grain yield. Increasing seeding rate failed to increase grain yield of the three cultivars, but ND 740 was most productive at the lowest seeding rate. Increasing the level of N significantly increased grain protein content (GPC) over all environments. Grain volume weight (GVW) and thousand kernel weight (TKW) decreased with increasing N level and were influenced by genotype. Increased seeding rate significantly increased plant stand and tiller number while increasing N levels significantly increased head count. These data indicate that although genotype was the primary factor in determining grain yield, GPC, and agronomic traits, individual genotypes responded differently to varying seeding rates and N management practices.

“…It may be due to the fact that nitrogen is an essential element for growth and development and thus promotes growth and yield parameters. Similar results are also reported by Ling & Silberbush (2002), Woolfolk et al, (2002), Bly & Woodard (2003), Oko et al, (2003), Siddiqui et al, (2008) and Otteson et al, (2007Otteson et al, ( & 2008 All fertilizer treatments were significantly better than the control. In addition, high plant response to fertilization portrays the clear finger prints of integration of soil and foliar feeding.…”

The study was carried out in Sewa Oasis, Egypt, in Tegthierty area whose soil is loamy sand in texture. Two field experiments were carried out depicting the application of three N levels in three methods namely soil, foliar, or combinations of both methods. The application of N via soil or foliage separately was on the purpose of exposing the effects of such routes in a clear cut as being not affected by the other levels or routes. These treatments were assessed in two successive seasons. Wheat variety Sakha 93 was the test plant. The aim of this study was to approach the goal yield of wheat by using the least possible N level via either soil, foliar, or both. It was found that all N fertilization levels and methods proved to be significantly better than the control treatment regarding wheat grain, straw, and biomass yields, growth parameters, and NPK uptake in both plant parts, as well in both seasons of study. The best combination treatment was found to be the integrated soil and foliar application of fertilizer N at the highest rate.

“…Furthermore, the influence of a foliar N application was considered in none of these studies. Woolfolk et al (2002); Bly and Woodard (2003) and Tea et al (2004) studied the influence of a foliar N application on various quality parameters, but not on bread volume. For example Wieser and Kieffer (2001) found a strong influence of the gliadin/glutenin ratio on rheological properties and bread volume, but this could not be confirmed by Pechanek et al (1997).…”

Wheat is the second biggest staple crop worldwide and is mainly consumed in the form of baked goods, requiring a specific flour quality. Grain protein concentration (GPC) is an underpinning parameter for baking quality and therefore strongly influences the value of wheat. It is a common strategy to increase GPC by combining high protein varieties with the application of a late dose of nitrogen. However, the late use of N fertilisers can cause environmental problems, such as nitrate leaching and gaseous losses. Furthermore, recent studies show, that there is only a weak relationship between GPC and bread volume. The aim of this study was to re-evaluate the merits of a late N application by investigating the effects of a late foliar N application, not only on GPC, but also on the gluten protein composition and on bread volume.In this study, an increasing GPC did not necessarily lead to improved baking quality. Baking performance rather depended on the grain protein composition. Only at a low N fertiliser level (100 kg N ha −1 ), the foliar N application decreased the HMW-GS/LMW-GS ratio and increased the gliadin/HMW-GS ratio, which led to an improved bread volume. These results imply that a late foliar N application can be used to effectively improve baking quality when the total N uptake was low due to low fertilisation or unfavourable weather conditions. The results also show that quality cannot be evaluated by measuring GPC alone but also needs information of storage protein composition as well as bread volume.
