“…Thus, the grain protein is diluted accordingly within each kernel (Simmonds, 1995). Furthermore, this agrees with the underlying mechanisms for grain protein concentration: sink and source regulation impact N accumulation in cereal grains; the accumulation of N within the grain and of dry matter in grain are independent (Kato, 2012).…”

Nitrogen and water are two key factors for wheat production due to their major roles in plant growth and development, photosynthesis, yield, and grain protein content. Plant uptake of water and N is fundamentally interactive. Our objectives were: (a) to analyze the effects of different irrigation (IR) and N rates on spring wheat (Triticum aestivum L.) yield and grain protein, and spectral indices (relative greenness [SPAD] and Normalized Difference Vegetation Index [NDVI]), and (b) to identify the optimum IR and N requirements for wheat grain production in semi‐arid conditions of Montana and Idaho. This article details the results from field experiments conducted at three locations for two growing seasons (6 site‐years). Relative greenness measured by SPAD chlorophyll meter was used to assess plant N status, whereas NDVI was used for both plant N status and estimation of wheat yield. Both SPAD and NDVI values increased as N and IR application rates increased. The SPAD and NDVI values explained 80 and 84% of the variation in wheat yield, respectively. We found that IR at 75% of evapotranspiration (ET) throughout the growing season is adequate to optimize wheat yield and grain protein. Nitrogen rate was not correlated with wheat yield at any of the site‐years. Based on this study's results, approximately 150 kg N ha−1 (total, soil residual N plus N added as fertilizer) may be sufficient to optimize yield and grain protein content of irrigated spring wheat in semi‐arid cropping systems.

“…The relationship between above-ground biomass and grain weight is likely to be due to the positive correlation between leaf surface area and total photosynthesis per unit ground area [33,51]. Previous studies using destructive methods also showed a strong relationship between biomass and grain weight in both hard and soft wheat genotypes [25,52,53].…”

Understanding the Interactions between Biomass, Grain Production and Grain Protein Content in High and Low Protein Wheat Genotypes under Controlled Environments

Grain protein content (GPC) is a key quality attribute and an important marketing trait in wheat. In the current cropping systems worldwide, GPC is mostly determined by nitrogen (N) fertilizer application. The objectives of this study were to understand the differences in N response between high and low GPC wheat genotypes, and to assess the value of biomass growth analysis to assess the differences in N response. Six wheat genotypes from a range of high to low GPC were grown in low, medium and high N, under glasshouse conditions. This experiment was designed around non-destructive estimation of biomass using a high throughput image-based phenotyping system. Results showed that Spitfire and Mace had higher grain N% than Gazelle and QAL2000, and appeared to demand more N to grow their biomass. Moreover, at low N, Spitfire grew faster and achieved the maximum absolute growth rate earlier than high N-treated plants. High grain N% genotypes seem able to manage grain N reserves by compromising biomass production at low N. This study also indicated the importance of biomass growth analysis to show the differences in the N responsiveness of high and low GPC wheat.

“…In addition, no qualitative analysis of grain protein was performed in our study. According to the literature (Benin et al, 2012;Kato, 2012;Dostálová et al, 2015), the total protein content of cereals is most affected by N, and S improves the qualitative protein composition. The amount of starch in grains decreased with increasing fertilisation rates.…”

In 2019-2021, the experiment was carried out with the aim to investigate how sulphur (S) fertiliser rates under different nitrogen (N) fertiliser backgrounds influenced winter wheat grain yield, grain quality, and plant productivity indicators. The winter wheat (Triticum aestivum L.) cultivar 'Janne' was grown in four N background treatments with N 60 , N 120 , N 180 , and N 240 without S fertilisation and also fertilised with S 15 (in all N fertilisation treatments), S 30 (only with N 120 and N 240 ), and S 60 (only with N 240 ). The results showed that S fertilisation increased the wheat grain yield significantly in individual research years and only in the plots fertilised with higher N rates. N fertilisers increased the protein content, sedimentation, and gluten content of the grain, while S fertilisers only in one year and only in the N 180 fertilisation treatment. The results of experiment showed that the N:S ratio for the winter wheat at the BBCH 30 growth stage was in the range of 8-16, and at the BBCH 65 it was in the range of 9-19 indicating that the winter wheat was optimally or even more than optimally supplied with S.
