“…The application of slow and controlled release fertilizers reduces environmental pollution in terms of hazardous gaseous emissions and water eutrophication (Azeem et al 2014) and simultaneously enhances nitrogen use efficiency (Ladha et al 2005) which is an important presupposition for the increased profit of production (Beatty et al 2010;Gaju et al 2011). However, the use of these fertilizers is substantially limited by their higher cost (Zebarth et al 2009).…”

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.

“…So, split N application regimes result in considerable boost in NUE, production, and resultantly RUE by reducing losses and improving uptake [41]. It is a rising concern that most of the available or applied N is lost, thereby reducing NUE, which is just 29% for cereals in developing agrarian economies [55,56]. This research study was carried out to validate the influence of split N application on biomass accumulation, grain yields, and resource use efficiencies such as NUE and RUE for C 3 winter and C 4 summer cereals.…”

Abstract:Resources are limited, thus improving resource use efficiency is a key objective for cereal-based cropping systems. This field study was carried out to quantify resource use efficiencies in selected C 3 and C 4 cereals under split nitrogen (N) application regimes. The study included the following treatments: six cereals (three C 3 : wheat, oat, and barley; and three C 4 : maize, millet, and sorghum) and four split N application regimes (NS 1 = full amount of N at sowing; NS 2 = half N at sowing + half N at first irrigation; NS 3 = Results revealed that C 4 cereals out-yielded C 3 cereals in terms of biomass production, grain yield, and resource use efficiencies (i.e., radiation use efficiency (RUE) and nitrogen use efficiency (NUE)), while splitting N into three applications proved to be a better strategy for all of the selected winter and summer cereals. The results suggest that C 4 cereals should be added into existing cereal-based cropping systems and N application done in three installments to boost productivity and higher resource use efficiency to ensure food security for the burgeoning population.

“…Many studies on genetic variation for NUE in various crops reported large interactions between genotype and N stress and other environmental conditions (Cabrera-Bosquet et al 2007, Anbessa et al 2009, Beatty et al 2010, Wei et al 2012, Chen et al 2013). The investigations of Bouchet et al (2014), using an oilseed rape mapping population are a good example of such studies in which they determined genomic regions (Quantitative Trait Loci (QTLs)) associated with yield and assessed their stability under contrasting nitrogen nutrition regimes.…”

“…The definition of NUE applied in this study is the yield produced per unit of added N (Dresbøll and Thorup-Kristensen 2014). NUE is already an important target for breeding research in many crops such as wheat (Cabrera-Bosquet et al 2007), barley (Anbessa et al 2009, Beatty et al 2010, rice (Wei et al 2012, Chen et al 2013, and oilseed rape (Koeslin-Findeklee et al 2014).…”
