“…It has been shown that a limited N supply constrains crop production globally by influencing the crops' growth and development [20,38]. For example, N deficiency can decrease barley yield, shorten the growth period and also decrease total biomass, the N content of organs and a series of enzyme activities [39][40][41].…”

Nitrogen (N) stress seriously constrains barley (Hordeum vulgare L.) production globally by influencing its growth and development. In this study, we used a recombinant inbred line (RIL) population of 121 crosses between the variety Baudin and the wild barley accession CN4027 to detect QTL for 27 traits at the seedling stage in hydroponic culture trials and 12 traits at the maturity stage in field trials both under two N treatments, aiming to uncover favorable alleles for N tolerance in wild barley. In total, eight stable QTL and seven QTL clusters were detected. Among them, the stable QTL Qtgw.sau-2H located in a 0.46 cM interval on the chromosome arm 2HL was a novel QTL specific for low N. Notably, Clusters C4 and C7 contained QTL for traits at both the seedling and maturity stages. In addition, four stable QTLs in Cluster C4 were identified. Furthermore, a gene (HORVU2Hr1G080990.1) related to grain protein in the interval of Qtgw.sau-2H was predicted. Correlation analysis and QTL mapping showed that different N treatments significantly affected agronomic and physiological traits at the seedling and maturity stages. These results provide valuable information for understanding N tolerance as well as breeding and utilizing the loci of interest in barley.

“…The grain yield is a principle criterion for evaluating efficiency of various treatments because ultimate effects of (Kaur and Satyavan, 2020). It was attributed to its better genetic growth parameters which intercepted higher solar radiation and leads to more photosynthesis that positively affected the translocation of assimilated photosynthates from source to sink and resulted in higher grain yield.…”

A field experiment was conducted during the winter (rabi)season of 2017–18 and 2018–19 at the Chaudhary Charan Singh Haryana Agricultural University, Hisar, to study the effect of saline water irrigation on growth indices in 4 varieties (‘BH 902’, ‘BH 946’, ‘BH 885’ and ‘DWRB 101’) of barley (Hordeum vulgare L.) at different nitrogen levels (0, 30, 60 and 90 kg/ha). The results showed that, during early growth period both 6-row barley varieties ‘BH 902’ and ‘BH 946’ recorded significantly higher crop-growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR), specific leaf weigth (SLW) and leaf-area duration (LAD) than both 2-row barley varieties ‘BH 885’ and ‘DWRB 101’, whereas ‘BH 885’ and ‘DWRB 101’ varieties attained higher values of RGR and NAR after 90 days after sowing (DAS). The CGR and LAD recorded maximum values between 61 and 90 DAS, while RGR and NAR showed the highest values up to 30 DAS irrespective of varieties and nitrogen levels. Application of 90 kg N/ ha significantly enhanced the CGR up to 90 DAS, RGR up to 30 DAS and LAD up to 120 DAS, while NAR values were significantly increased up to 60 DAS with 30 kg N/ha and SLW up to 90 DAS with 60 kg N/ha. The RGR, NAR and SLW were significantly decreased with the application of different nitrogen levels between 91 and 120 DAS as compared to the control. The variety ‘BH 946’ gave the highest grain yield of 5.15 t/ha, being 5.1, 7.3 and 14.7% higher than ‘DWRB 101’, ‘BH 902’ and ‘BH 885’, respectively. Different varieties responded to N application only up to 60 kg/ha. Grain yield of barley was positively correlated with CGR, SLW and LAD but negatively with RGR.

“…Many researches have confirmed the important role of nitrogen fertilizer in the formation of plant growth characteristics, especially number of shoots, plant height, and the ratio of leaves to stems [5,6]. The nitrogen enters the structural construction of many vital compounds such as amino acids, protein, nucleic acids and secondary compounds.…”

A field experiment was carried out in Babylon Governorate, Al-Qasim Green University - College of Agriculture -in the fields Continue of the Field Crops Department during the winter agricultural season at 2022-2023 to study the response of three cultivars of black barley “Zanbaka”, “Mosul 1” and “Local Black” to add nitrogen fertilizer at level of 0, 60 and 120 kgNha-1, the combinations of treats were distributed in a factorial experiment according to Randomized Complete Block Design (RCBD) with three replicates. The data were collected and analyzed according to the variance analysis table and the averages were tested according to least significant difference (LSD) at probability level 0.05. The results showed a significant superiority of “Zanbaka” cultivar in the appearances of main stem height and number of grains in spike, while cultivar “Mosul 1” were significantly superiorin flag area, total chlorophyll, number of spikes, weight of 1000 grains, biological yield, and total grain yield (3.44 tons ha-1), while the fertilizer at level 60 kgNha-1 significantly superior in flag area, total chlorophyll, number of spikes, number of grains, weight of 1000 grains, biological yield, and total grain yield (3.82 tons ha-1). It was significantly superior to the intervention treatment, Zanbaka x 120 kg.ha-1, in terms of main stem height. It also significantly outperformed the intervention treatment of Mosul 1 Cultivar × 60 kgNha-1 In the characteristics of the leaf area, the total chlorophyll pigments index, the weight of a thousand grains, the grain yield of 4.05 tons ha-1, and the harvest index.
