“…Compared to the low-N rate, the high-N fertilization rate resulted in even higher increase in grain N (29.2% on average). It is well-known that increasing soil N availability increases yield more than grain N until a yield maximum is reached, whereas grain N concentration increases if soil N availability is increased further (Varga & Svečnjak 2006). Thus, our results indicate that maximum grain yields were achieved at the high-N fertilization rate in a given environmental conditions.…”

Three winter wheat cultivars were grown under low-N and high-N fertilization rates over two growing seasons. In spite of smaller 1000-grain weight, the high-N fertilization produced higher grain yields as well as grain N and trace element concentrations in both growing seasons. Trace element increments with high-N rate averaged 14.0% for Fe, 9.2% for Zn, 19.7% for Mn, 13.2% for Cu, 15.1% for Ni, and 23.0% for Cd. Only Na concentration was unaffected by N fertilization, whereas Pb and Cr were below detection limits. Absolutely small, but significant differences existed among tested cultivars for all trace elements and these cultivar effects were uniform on both N fertilization rates. However, cultivars differed in their rankings for trace element concentrations across two growing seasons and these specific responses appeared to be closely related to grain N.

“…Moreover, the granular soil N late-season distribution significantly increased TW and grain hardness of common wheat, as a probable consequence of the increase in GPC, but did not lead to any significant differences for durum wheat. Varga and Svečnjak (2006) reported increased kernel weight for late-season N, but only when the plants had been supplied with below optimum N during the prior growth stages, while the increase in TW after late-season N application was always significant. On the other hand, Ruske et al (2003) observed a linear increase in TW when extra N was applied as foliar urea at anthesis, but not for the late soil application of ammonium nitrate.…”

“…A significant positive effect of foliar N applications on increasing the GPC of common and durum wheat has been reported for several irrigated or high rainfall systems (Altman et al, 1983;Ruske et al, 2004;Tea et al, 2007;Varga and Svečnjak, 2006) and in low rainfall environments (Bly and Woodard, 2003;Orcen et al, 2013;Woolfolk et al, 2002). An effect of foliar N fertilizer applications on grain yield has been reported in a few cases, although decreased yields following late urea spraying have been observed in other cases (Barraclough and Haynes, 1995;Peltonen et al, 1991).…”

“…Foliar application is less effective at increasing the grain N content when large amounts of N have previously been applied (Gooding and Davies, 1992). Varga and Svečnjak (2006) reported that the benefits of late season foliar applications are influenced by both the cultivar and the plant N status.…”

ABSTRACTe foliar N application at a low rate is a strategy that could be applied by farmers in substitution to the traditional late soil application when there are restrictions on N distribution. e aim of this study was to compare the e ect of late-season N fertilization strategies on wheat (Triticum spp.) quality. Field experiments were set up in two di erent soils, in Northwest Italy. e e ect of N fertilization was evaluated on two common (T. aestivum L.) and two durum wheat (T. turgidum L. var. durum Desf.) cultivars. Late-season N was soil-applied (40 kg N ha -1 ) as ammonium nitrate at heading, or foliar sprayed (5 kg N ha -1 ) at owering, and compared with a control without N fertilization a er the vegetative growth stage. Nitrogen soil application increased grain protein content (GPC) (+15%) for both crops. is fertilization strategy led also to higher test weight (+1.4%), kernel hardness (+14%), dough strength (W) (+42%), and lower tenacity/extensibility ratio P/L (-18%) in the common wheat, and to a lower yellowberry percentage in the durum wheat (-29%). e strategy to apply a foliar N fertilizer at anthesis at a lower rate, although it has a greater cost e ectiveness, led to a less e ective bread-or pasta-making quality enhancement, with an average increase of GPC and W only in the silt loam soil by 5 and 18%, respectively. is strategy could lead to more successful increase of GPC in soils with a probable lower nitrate leaching during the vegetative stages.

Nitrogen (N) is an important plant nutrient and is crucial for the plant growth and grain yield formation of field crops such as wheat (Triticum aestivum L. ssp. aestivum). However, little is known about the influence of N on secondary metabolites in wheat grains which are supposed to be beneficial for human health due to their antioxidant potentials. Therefore, we investigated the influence of N fertilization on plant growth and yield performance of winter wheat, as well as on total phenolic concentration, antioxidant capacity, and the accumulation of (in)soluble phenolic acids in wheat grains during the grain‐filling phase. It was found that ferulic acid was the predominant phenolic acid in wheat grains. As expected, higher amounts of N fertilizer led to increasing grain yields, whereas the concentration of soluble ferulic acid decreased. In contrast, insoluble bound ferulic acid, total phenolic content, and antioxidant capacity were not affected by the N treatment. Insoluble phenolic compounds seemed to be less susceptible to variations in N supply.
