SUMMARYLimited information is available concerning the influence of nitrogen fertilization jointly on yield response, nitrogen use efficiency (NUE) and grain quality of durum wheat under semi-arid Mediterranean conditions. The study focused on evaluating, through a systematic study, over three seasons in southern Italy the effects of three nitrogen fertilization rates (0, 80 and 160 kg N ha−1– N0, N80and N160), on grain yield, yield components, nitrogen efficiency indices and grain quality characteristics of three durum wheat genotypes (‘Creso’, ‘Trinakria’ and ‘Line 25’) from different breeding eras to achieve a more sustainable fertilization management of the durum wheat crop. We found that nitrogen fertilization at 80 kg N ha−1was able to maximize the yield performances (2.1 t ha−1year–1) of the crop and keep NUE index at an acceptable level (16.3 kg kg−1). On the other hand, nitrogen fertilization at 160 kg N ha−1improved grain quality measured through protein (up to 14.3%) and dry gluten concentration (up to 12.8%), but had a detrimental effect on grain yield and nitrogen efficiency. Among the genotypes studied, ‘Trinakria’ showed the greatest potential to utilize nitrogen fertilization to improve grain yield and NUE (at N80) and quality (at N160), ‘Line 25’ made good use of N80both for yield and quality, whereas ‘Creso’ proved wholly unresponsive to nitrogen. The effect of N fertilization on grain yield and N use efficiency depends on rainfall distribution, giving the best results when about 80% of total rainfall occurred from sowing to heading. Overall, our data show that in seasons with regular rainfall in quantity and distribution, combining no more than 80 kg ha−1of nitrogen fertilization with genotypes characterized by a more efficient response to nitrogen, is a useful tool to improve the agronomic and quality performance of the crop, ensuring, at the same time, a more environment-friendly nitrogen fertilization.

In order to determine the nitrogen use efficiency of plantlets in vitro under different nitrogen source, near infrared spectroscopy technique and image analysis technique with multi-references were used to obtain the successive information of nitrogen consumption. The Logistic and nonlinear hyperbolic equations were used for fitting the relationship of biomass of plantlet in vitro and culture time, nitrogen utilization of plantlets and culture time, and nitrogen utilization of plantlets and biomass of plantlet in vitro. The models of growth prediction, nitrogen utilization and nitrogen use efficiency of plantlets in vitro were established. The nitrogen use efficiency of Atractylodes lancea plantlets in vitro sub-cultured in different nitrogen source and levels were measured, which decreased with the increase of culture time. Ammonium (0.096 g L-1) / nitrate (0.555 g L-1) was the preferred nitrogen sources combination for the growth of Atractylodes lancea plantlets in vitro.

Wheat requirement of nitrogen for plant growth, and crop yields and quality depends upon substantial N inputs. Therefore, a field experiment was carried out at Gimbichu district in 2017 and 2018 main cropping season with the objective of evaluating the overall performance of applying slow-release/UREAstable fertilizer over the conventional urea fertilizer for durum wheat production, and to determine optimum rates of slow-release urea fertilizer for wheat productivity. The treatments consisted of Control, 90 kg N ha-1 from conventional urea applied in split, 90 kg N ha-1 from UREAstable applied once at planting, 90 kg N ha-1 from UREAstable applied in split, 45 kg N ha-1 from UREAstable applied once at planting, 45 kg N ha-1 from UREA stable applied in split form, 135 kg N ha-1 from UREA stable applied in split form, 135 kg N ha-1 from conventional UREA applied in split form and 135 kg N ha-1 from UREAstable applied once at planting. The results revealed that plant height, spike length, Tiller number, grain yield, biomass yield, harvest index and grain and straw uptake were significantly (P<0.05) affected by the application of slow release and conventional urea fertilizer. The highest spike length (3.8cm), Tiller number (2.1), grain yield (2205 kg ha-1), biomass yield (6968 kg ha-1) and nitrogen grain straw uptake (35.6 kg N ha-1) were recorded from 135kg N ha-1 urea stable fertilizer applied in split form followed by application of 135 kg N ha-1 conventional urea fertilizer applied in split form. While, maximum straw nitrogen uptake was obtained from application of 135 kg N ha-1 conventional urea fertilizer applied in split form. Therefore, taking the findings of the present study consideration it may be concluding that farmers can use 135 kg N ha-1 UREAstable fertilizer to improve nitrogen use efficiency and productivity of wheat in the study area in addition to conventional urea fertilizer. However, further research may be required at various locations to come up with an inclusive recommendation.

In wheat, the increase in nitrogen use efficiency (NUE) and optimization of the nitrogen doses to be used are both very important aspects for improving sustainable and productive agriculture. The aim of this study was to investigate, under rainfed Mediterranean conditions, the influence of strobilurin treatment and N fertilization on durum wheat N use efficiency for yield (NUEy) and protein (NUEp) and on the contribution of their components, nitrogen uptake efficiency (UPE) and nitrogen utilization efficiency (NUtE). Two durum wheat cultivars (Saragolla and Sfinge) were grown for two years in field conditions under five nitrogen treatments (60 kg ha−1 N60; 90 and 120 kg ha−1 given two and three times; N90, N90T3, N120 and N120T3) comparing a control without strobilurin treatment (ST0) and one application of strobilurin (STaz). In Sfinge, STaz caused a decrease in UPE and NUEp and an increase in NUtE and NUEy. In Saragolla, the opposite behavior was observed. Moreover, strobilurin positively affected the contribution of UPE and negatively that of NUtE to NUEy only in Saragolla. Furthermore, strobilurin determined higher NUEy and NUEp values under most of the N treatments adopted in the drier year. With this study, we supported the hypothesis that in Mediterranean conditions, the possibility of reducing N rate application from 120 to 90 kg ha−1 with a strobilurin-based treatment, even in the absence of fungal diseases, could represent a useful agronomic strategy for durum wheat grown under drought conditions as those predicted under the ongoing climate change.
