“…In this study, straw N concentration in NE was significantly lower than that in ND, while the grain N concentration was the same between these two hybrids (Table 3). These results were contrary to the previous statement that the rise in grain yield would lead to a fall in protein to starch or oil ratio (Dudley et al 1977;Triboi and Triboi-Blondel 2002;Triboi et al 2006). As a result, we concluded NE could potentially increase grain yield and, simultaneity maintain similar grain-N concentration as compared to common hybrid of ND.…”

Best nitrogen (N) management and Nefficient cultivars were two main strategies used to add N capture from soil, environment and fertilizer N sources, and increase grain yield and N use efficiency (NUE). This study aimed to evaluate the interaction between genotypic difference and nitrogen management strategy and to determine optimal N management strategy for summer maize hybrids (Zea mays L.) in China. Two on-farm experiments with six N levels and two maize hybrids (NE and ND) were conducted in HM County of the North China plain (NCP) in 2005 and 2006. The maize hybrid of NE has proved to have higher grain yield potential with lower N applications, compared to ND of the major commercial hybrid in the NCP. Calculated maximum grain yield of NE reached 9.3 and 7.7 t ha −1 using grain response curve, compared to 6.4 and 6.4 t ha −1 for ND in 2005 and 2006, respectively. No N fertilizer and only 79 kg N ha −1 for NE were required to achieve the maximum grain yield of ND, which required 150 and 116 kg N ha −1 in 2005 and 2006, respectively. Compared with those of ND, high N stress tolerance, low N demand with low straw N concentration and high growing capacity after ten-leaf stage were main reasons to achieve higher grain yield with lower N fertilizer application for NE. Although calculated optimal N rates for NE by grain yield response curve were significantly higher than these for ND, no differences were observed before the ten-leaf stage. Therefore, we conclude that more N fertilizer should be applied after ten-leaf stage for higher grain yield potential hybrid of NE in comparison to common hybrid of ND.

“…Similarly, grain yield of cultivars increased strongly relative to year of release in CONMIN, whereas there was only a minor increase in BIODYN 2. 18 These results confirm the close correlation between grain yield and grain N uptake (in our study r = 0.95 and P < 0.0001), also postulated in Triboi et al 59 In contrast to N uptake, the N efficiency components NUpE, NUtE and Nit-UE generally decreased as a function of N input and were lowest in the conventional system CONMIN ( Table 5). The results reflect improved NUpE and Nit-UE with decreasing N supply and improved NUtE by applying organic fertilisers at low doses.…”

“…Generally, in Croatia in year 2010 yield, test weight and thousand grain weight of wheat were reduced by 20 %-50 %. Many authors noticed that under such extreme climatic conditions a significant yield decrease leads to an increase in protein to starch ratio and vice versa (Qury et al, 2003;Triboi et al, 2006;Drezner et al, 2007). As a result of quantitative changes in proteins distribution in 2010, the GLI/GLU ratio was increased in comparison to 2009 (1.66 and 1.56, respectively) (Table 3).…”

The crude protein and protein components of fourteen commercial bread wheat cultivars grown in Eastern Croatia over two years and three locations were evaluated. Protein components were measured by reversed phase -high pressure liquid chromatography. A dominant effect of genotypes was obtained for the proportion of albumins and globulins, γ-gliadins and total glutenins, while year had a more pronounced impact on crude protein, total gliadins and high molecular weights and low molecular weights glutenin subunits. Locations had the strongest influence on total extracted proteins. Variability of gliadins to glutenins ratio was at the same extent influenced by the genotype and the year. Among interactions, genotype x year and year x location had the highest impact on evaluated proteins. The principal component analysis showed that wheat cultivars were differentiated according to variability of grain protein components. Considering the significant impact of proteins on the wheat bread-making quality, cultivar classification by protein components significantly contributes to the improvement of breeding program towards the creation of high quality cultivars.
