Diverse concepts of breeding for nitrogen use efficiency. A review (2017, background): “Barraclough et al. (2010) confirmed this and concluded that grain yield, grain %N, total N uptake, and N harvest index are the most important variables to improve NUE in wheat.”
Maximum Attainable Wheat Yield and Resource‐Use Efficiency in the Southern Great Plains (2015, background): “1A) confirms the previously reported tradeoff between both variables (Barraclough et al., 2010).”
Managing the Nutrition of Plants and People (2012, neutral): “Nitrogen utilisation efficiency (NUtE) often contributes more than N uptake efficiency (NUpE) to agronomic N use efficiency (NUE) when plants are grown with a low N supply [21, 85–87].”
Five decades of selection for yield reduced root length density and increased nitrogen uptake per unit root length in Australian wheat varieties (2016, background): “…the Australian wheat phenotype is unique, as selection for yield in bread wheat in UK and Argentina, and durum wheat in Italy has had little or no effect on nitrogen uptake (Austin et al. 1980; Slafer and Andrade 1993 Giunta et al. 2007; Barraclough et al. 2010; see review by Sadras et al. 2016).”
Breeding for increased nitrogen‐use efficiency: a review for wheat (T. aestivum L.) (2016, background): “Numerous studies detected significant G 9 N interactions for agronomic traits (e.g. Ortiz-Monasterio et al. 1997, Le Gouis et al. 2000, Laperche et al. 2006a, Barraclough et al. 2010, Cormier et al. 2013), meaning that the genetic values of varieties differ between N levels.”
Prospects of doubling global wheat yields (2013, background): “Proportionally however, the larger N-inputs are not matched proportionally by increase grain N, resulting in a lower overall nitrogen use efficiency (Barraclough et al. 2010).”
High Throughput Field Phenotyping of Wheat Plant Height and Growth Rate in Field Plot Trials Using UAV Based Remote Sensing (2016, methodology): “This study used data collected over the Defra-funded WGIN (Wheat Genetic Improvement Network) Diversity Field Experiment conducted at Rothamsted, which is testing the influence of four different nitrogen fertiliser treatments (0, 100, 200, 350 kg N ha−1) on 25 varieties of wheat, with each treatment”
Synergistic Effect of Sulfur and Nitrogen in the Organic and Mineral Fertilization of Durum Wheat: Grain Yield and Quality Traits in the Mediterranean Environment (2018, background): “In fact, if on the one hand it has been proved that nitrogen positively affects grain yield and quality, on the other hand N fertilizer management is pivotal to avoiding N losses caused by leaching, runoff, denitrification or volatilization [11,16,17].”
Quantifying how winter wheat crops accumulate and use nitrogen reserves during growth (2012, background): “However, current elite varieties only ake up a limited proportion of this applied N, typically 50–60% or winter wheat (Bloom et al., 1988; Barraclough et al., 2010) nd large amounts of N are lost to the environment.”
Nitrogen partitioning and remobilization in relation to leaf senescence, grain yield and grain nitrogen concentration in wheat cultivars ☆ (2014, background): “However, in an examination of 39 UK varieties, Barraclough et al. (2010) found that NUtE explained more of the variation in grain yield than NUpE at 5 N rates.”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, neutral): “Nitrogen was applied at three levels (100, 200 and 350 kg N/ha) (Barraclough et al., 2010). Ears were tagged at anthesis and whole caryopses were harvested from the middle part of the ear at 14, 21, 28 and 35 days post-anthesis (DPA) and frozen at −80 °C for RNA extraction. RNA was extracted using a”
