“…These results agree with the observations of several other studies [62][63][64]. In general, water deficit during the wheat growth period and around anthesis causes yield losses due to reduction in potential grain number per unit of land area [65]. Drought stress and high temperatures during grain filling can reduce the mean kernel weight by decreasing daily rates of translocation of carbohydrate reserves from the vegetative organs of the plant to the grain [66].…”

Wheat grain protein content (GPC) is a key component when evaluating wheat nutrition.It is also important to determine wheat GPC before harvest for agricultural and food process enterprises in order to optimize the wheat grading process. Wheat GPC across a field is spatially variable due to the inherent variability of soil properties and position in the landscape. The objectives of this field study were: (i) to assess the spatial and temporal variability of wheat nitrogen (N) attributes related to the grain quality of winter wheat production through canopy fluorescence sensor measurements; and (ii) to examine the influence of spatial variability of soil N and moisture across different growth stages on the wheat grain quality. A geostatistical approach was used to analyze data collected from 110 georeferenced locations. In particular, Ordinary Kriging Analysis (OKA) was used to produce maps of wheat GPC, GPC yield, and wheat canopy fluorescence parameters, including simple florescence ratio and Nitrogen Balance Indices (NBI). Soil Nitrate-Nitrogen (NO 3 -N) content and soil Time Domain Reflectometry (TDR) value in the study field were also interpolated through the OKA method. The fluorescence parameter maps, soil NO 3 -N and soil TDR maps obtained from the OKA output were compared with the wheat GPC and GPC yield maps in order to assess their relationships. The results of this study indicate that the NBI spatial variability map in the late stage of wheat growth can be used to distinguish areas that produce higher GPC.

“…Even though higher NUtE values could be explained according to Montemurro et al (2006) as a result of increased post-anthesis nitrogen uptake from the soil, the higher NUtE recorded in the CULTAN treatment could be explained rather by tendency to lower grain protein content in the CULTAN treatment compared to the conventional one which is in accordance with the findings of Albrizio et al (2010) and Sedlar et al (2013).…”

The influence of the injection of nitrogen fertilizers with the CULTAN system (Controlled Uptake Long Term Ammonium Nutrition) on nitrogen uptake by winter wheat (Triticum aestivum L.) was observed at small-plot field experiments under conditions of the Czech Republic (central Europe) during 2007-2013. The CULTAN system consisting in the injection of all the nitrogen in one dose was compared with conventional broadcast surface fertilization which is carried out in three partial nitrogen doses. The total nitrogen dosage was 150 kg N.ha -1 . If the CULTAN fertilization was carried out at the beginning of tillering of winter wheat (BBCH 22) instead of at the end of tillering (BBCH 29), the CULTAN-treated winter wheat did not suffer from nitrogen deficiency at the BBCH 45 (boot stage) and BBCH 51 (beginning of heading) growth stages. Nitrogen utilization efficiency and biomass production efficiency were significantly higher with the CULTAN treatment compared to the conventional fertilization whereas nitrogen uptake efficiency tended toward lower values with the CULTAN treatment. Nitrogen use efficiency (NUE), post-heading nitrogen uptake, the contribution of nitrogen translocation to the total nitrogen in grain, the partial factor productivity of nitrogen as well as grain yield were not significantly influenced by the CULTAN system. Prolonged nitrogen uptake from the soil with the CULTAN treatment resulting in delayed plant senescence was not confirmed. Neither an application of sulphur-containing fertilizer nor the increased dosage of nitrogen (200 kg N.ha -1 ) positively affected the studied parameters.

“…Similar to our reults, the increase in WUEET with N fertilization has been reported by Albrizio et al (2010). The decrease in WUEET with the highest levels of N (210 kg N ha -1 ) at all levels of irrigation could be ascribed to the decrease in grain yield with excessive levels of N fertilization.…”

Little information is available on the role of optimized application of irrigation and N on crop N recovery and NO3-N build up and movement in soil profile. A field experiment was carried out to evaluate the effects of irrigation and N management practices on wheat yield, water and fertilizer use efficiency and NO3-N distribution in soil. The treatments included were three levels of irrigation; 0.7, 1.0 and 1.3% of the estimated evapo-transpiration (ETc) and four levels of N; 0, 110, 160 and 210 kg N ha -1 in split plot design. The N was applied either in two splits (50% at sowing + 50% at maximum tillering) or three splits (50% at sowing + 25% at maximum tillering + 25% at spike initiation). Nitrogen applied at 110 kg ha -1 in three splits produced higher wheat yield, N recovery and water use efficiency (WUE) than two splits. Further, application of N in three splits had considerably lesser accumulation of NO3-N in soil as compared to two splits. A significant irrigation effect was observed on grain yield, N recovery and WUE. The highest levels were achieved with water application according to crop water requirement (1.0 ETc). The deficit irrigation produced significantly lower grain yield (3.15 t ha ). Deficit irrigation resulted in higher build up of NO3-N in surface soil. In contrast, excessive irrigation resulted in greater concentration of NO3-N in lower depths of soil. The results from this research show that there is great potential for decreasing N leaching and increasing wheat crop yield and N use efficiency thorugh controlled irrigation and N application according to crop demand.
