“…For wheat development, the timing of N availability is very important as it affects the number of tillers, number of ears per tiller, number of grains per ear, thousand grain weight, and N concentration in the grains (Darwinkel 1978;Osman et al 2012). Although winter wheat can root deep (up to 2.0 m, see Table 1), the nutrients that accumulate in the grains need to be taken up during a crop stage when the nutrient uptake of the root system has already decreased (Spiertz and Ellen 1978).…”

Cropping systems require careful nitrogen (N) management to increase the sustainability of agricultural production. One important route towards enhanced sustainability is to increase nitrogen use efficiency. Improving nitrogen use efficiency encompasses increasing N uptake, N utilization efficiency, and N harvest index, each involving many crop physiological mechanisms and agronomic traits. Here, we review recent developments in cultural practices, cultivar choice, and breeding regarding nitrogen use efficiency. We add a comparative analysis of our own research on designing breeding strategies for nitrogen use efficiency in leafy and non-leafy vegetables, literature on breeding for nitrogen use efficiency in other vegetables (cabbage, cauliflower), and literature on breeding for nitrogen use efficiency in grain crops. We highlight traits that are generic across species, demonstrate how traits contributing to nitrogen use efficiency differ among crops, and show how cultural practice affects the relevance of these traits. Our review indicates that crops harvested in their early or late vegetative phase or reproductive phase differ in traits relevant to improve nitrogen use efficiency. Headforming crops (lettuce, cabbage) depend on the prolonged photosynthesis of outer leaves to provide the carbon sources for continued N supply and growth of the photosynthetically less active, younger inner leaves. Grain crops largely depend on prolonged N availability for uptake and on availability of N in stover for remobilization to the grains. Improving root performance is relevant for all crop types, but especially shortcycle vegetable crops benefit from early below-ground vigor. We conclude that there is sufficient genetic variation available among modern cultivars to further improve nitrogen use efficiency but that it requires integration of agronomy, crop physiology, and efficient selection strategies to make rapid progress in breeding. We also conclude that discriminative traits related to nitrogen use efficiency better express themselves under low input than under high input. However, testing under both low and high input can yield cultivars that are adapted to low-input conditions but also respond to high-input conditions. The benefits of increased nitrogen use efficiency through breeding are potentially large but realizing these benefits is challenged by the huge genotype-byenvironment interaction and the complex behavior of nitrogen in the cropping system.

“…Osman et al (2012) argued that in order to increase grain N content in bread wheat, an increase in NUpE is more effective as increasing NUtE would decrease grain protein content. This last aspect was also noted by Barraclough et al (2010) and Górny et al (2011): they found a negative correlation between grain-NUtE and grain %N.…”

“…Varieties with high quality protein and better nitrogen uptake were recommended for organic farming purposes by Osman et al (2012), as lower protein content was typically found at the organic sites. In the present experiment varieties were identified with high-quality protein, such as Lorenzo, Hendrix, Butaro, Montdor and Stefano (Table 5 and Figure 1 in Rakszegi et al 2016), which could be beneficial when growing them under organic conditions.…”

“…The protein content was found to be lower at the organic site, so varieties with high-quality protein and better nitrogen uptake were recommended for oganic farming purposes to compensate for the relatively low protein content of the grain (Osman et al 2012). …”

The processing quality of 37 wheat varieties grown in Hungary and Austria (2011-2013) were assessed under organic and conventional low input management. The varieties studied were developed using three breeding strategies (conventional, organic and their combination: BFOA). The aim was to evaluate the effect of the field management and to assess the performance of varieties developed using different breeding methods, based on their quality traits under different managements. Furthermore, properties were identified that could characterize wheat quality and be used effectively for selection under both types of growing conditions. Strong year and genotype effects were found for all the quality traits (protein, starch, gluten, GI, Zeleny, Farinograph water absorption, development time, stability and quality number, falling number, flour yield, hardness index) of the studied varieties, while the effect of the management was significant for the physical properties (test weight, thousand-kernel weight, hardness) and gluten quality characters (gluten spread, GI, dough stability) of the grain. The standard deviation of the gluten quality traits characterized the differences between the breeding 3 strategies. It proved possible to pre select organic varieties for quality traits with high broad-sense heritability under conventional growing conditions, but direct selection in organic fields is suggested for gluten quality characters.

“…The effect of farming system on Zeleny test (49.67 ml in organic system, 50.37 ml in conventional one) was not statistically significant (Table 1). Several studies declare significantly lower protein content in grain of wheat grown in organic farming systems (Hildermann et al, 2009;Osman et al, 2011). The statistically significant but small difference in protein content between compared systems could be explained by the grown variety Balada that belongs to elite quality varieties of winter wheat.…”

In the years 2003-2005 the field experiment was realized in the maize-barley growing region on degraded Chernozem. Two different farming systems -organic and conventional were compared. The yield and grain quality of winter wheat in organic and conventional farming system were evaluated. Winter wheat was used twice a crop rotation time -after pea and clover. The quality parameters of winter wheat (grain volume weight, protein content, Zeleny test, wet gluten content) were measured after harvest. The yield and grain quality parameters were statistically significantly affected by farming system, forecrop and weather conditions. Grain yield, grain volume weight, protein content and wet gluten content were significantly higher in conventional farming system than in organic one. Even though, grain quality of winter wheat in organic farming corresponded to elite (E) or standard (A) technological quality of wheat according to the Slovak Technological Standard STN 46 1100-2. The yield of winter wheat was increased and grain quality parameters were improved by using pea as the forecrop in comparison to clover.
