“…Water stress imposed during the grain filling period of wheat, especially at the early filling stage, usually results in a reduction in grain weight (Zhao et al, 2009). Further, Pierre et al (2008) andEL Sabagh et al (2015) reported that water deficit stress has a negative effect on grain weight. Protein content is more strongly influenced by environment (Mikhaylenko et al, 2000).Variations in flour quality in a hard-grained were related to changes in protein composition from drought stress during grain filling (Gooding et al, 2003).…”

Maize is considered one of the most essential dietary components in human food and animal feeding. The objectives of the present study were to quantify the effects of drought stress on qualitative traits of maize at grain-filling stages. Hybrids maize seeds were grown by applying full and water stress conditions during the grain filling stage. Various nutritional properties (crude oil, starch, grain protein content) were determined in 2014 and 2015 at the second crop growing season in Adana, Turkey. Based on the results of this study, genotype and environment were found to influence all quality traits significantly. Further, result of study suggest that water stress caused a significant reduction in major quality traits. Grain weight and grain quality yield as well crude oil, protein and ash yield were significantly decreased due to water deficit condition in the both growing seasons. Significant differences were observed among hybrids in respect of all measurements due to irrigation regimes. The genotypes, Sancia and Calgary were tolerant by producing higher grain weight. Accordingly, grain qualities of 71May69, Aaccel and Calgary maize hybrids were less affected under drought stress.

“…These processes can involve the source and sink relationships at certain crop stages (Bancal 2009), critical N dilution and crop N deficiency issues (Justes et al 1994;Lemaire and Gastal 2009), dependence of mineral nutrient stoichiometry on biomass production (Greenwood et al 2008), root characteristics related to the N metabolism and NUE Garnett et al 2009;Pedersen et al 2010), or the genes affecting aspects of NUE including N retranslocation and conservation (Waters et al 2009;Habash et al 2007;Fontaine et al 2009). Other research mainly focuses on grain quality, which is affected by soil N availability (Kindred et al 2008;Saint Pierre et al 2008). One particular physiological process has been discussed frequently in the context of NUE: There is great hope to increase the NUE of crops through enhanced efficiency of the photosynthetic system, for example by modifying or selecting for variation in RuBisCO activity.…”

Assessment of nutrient use in annual and perennial crops: A functional concept for analyzing nitrogen use efficiency

2010

The use of more nutrient-efficient crops is important for maintaining yields while enhancing environmental sustainability. Various approaches are being applied to evaluate aspects of plant nutrient use efficiency, among them ecological concepts based on accumulation and losses of biomass and nutrients, agronomic concepts with a major focus on agricultural crops and harvested products, and physiological approaches assessing single physiological processes important for nutrient use. Unfortunately, the various approaches are often not compatible. Here we propose, with the example of nitrogen (N) use efficiency (NUE) of cereals, to integrate the functionally important components of NUE in a common conceptual framework. We link productivity to N in crops and seeds and consider the whole life-cycle of the crop (including seeds). Three major components of NUE are separated: The N uptake efficiency, grain-specific N efficiency and grain N concentration. The three components combine to a measure of overall NUE in terms of the N yield in harvested grain per unit of N in seed grain or soil N. The concept can be applied for both annual and perennial plants, which is demonstrated with the examples of winter wheat and a perennial energy crop (Salix) grown in Central Sweden.

“…Baking products of superior quality require standardized improver wheat flour characterized by high protein (GPC) and gluten contents, strength of dough (W) and dough stability (Foca et al, 2007). In South Europe, superior quality common wheat (Triticum aestivum L.) flour is mainly obtained by adopting detailed crop practices, since the various pedo-climatic conditions can influence the growth of plants in an irregular way and thus lead to a variable response in the formation and accumulation of the reserves in kernels (Dupont and Altenbach, 2003;Saint Pierre et al, 2008;Troccoli et al, 2000).…”

Effect of late-season nitrogen fertilization on grain yield and on flour rheological quality and stability in common wheat, under different production situations

The increasing demand for a high and homogeneous technological quality of common wheat (Triticum aestivum L.) points out the necessity of improving wheat with by a higher protein (GPC) and gluten content, strength of dough (W) and dough stability. Among the current crop practices, late-season nitrogen (N) fertilization, from heading to flowering, is generally considered the practice that has the most effects on the storage proteins and technological quality of the grain. In order to explore the influence late-season N application can have on the dough properties and on the formation of homogeneous lots in more detail, a research was set up between 2007 and 2013, over 6 growing seasons at different sites in North West Italy using the Bologna cultivar in each of the trials. Three different late-season N fertilization strategies were compared: T1, control without a late distribution of N; T2, foliar N fertilization at flowering; T3, top-dress granular soil fertilization at the beginning of heading. A randomized complete block experimental design with four replicates was adopted. The grain yield, GPC, W and P/L indexes were analyzed. Moreover, the rheological and enzymatic properties of the samples were studied using a Mixolab ® analyser (Chòpin Technologies, Paris, France).Grain yield was found to be unaffected by the fertilization treatments, while the late N application (T2, T3) significantly increased GPC. Only the granular N fertilization (T3) increased the W index compared to T1, while the P/L index was not affected by any of the fertilization strategies. Furthermore, the T3 strategy was always more effective in reducing the variability of the W index than the T2 and the T1 strategies. Water absorption and dough development time were higher in T3, than in T1, while intermediate results were reached for T2. The effect of late-season N fertilization was also significant on the starch behaviour of the dough, as an increase in starch gelatinization and retrogradation was observed. In short, the top-dress granular N fertilizer applied at the beginning of heading (T3) led to a more constant increase in GPC and flour rheological quality than the foliar application. Moreover, the adoption of this fertilization strategy resulted in a reduction in qualitative variability under different environmental and soil conditions.
