“…Our results are in accordance with results found in Italian tomato cultivation [51] and even in experimental trials performed in California [21]. Finally, similar results were also highlighted for durum wheat and broccoli cultivated in Southern Italy by Tedone et al [52] and Conversa et al [53], respectively. Both authors reported that high nitrogen applications are required to achieve the highest values in terms of vegetation nutritional status and dry matter in both durum wheat and broccoli.…”

Processing tomato is an important worldwide horticultural crop. It is generally grown in high-input systems; nevertheless, plant responses to nitrogen fertilization, in terms of the effects on dry matter production and allocation to different plant organs, have yet to be investigated in depth. Moreover, information on the crop marginal net return and global warming potential (as an index of the environmental impact of crop cultivation) at different nitrogen rates is still scarce. Therefore, the aim of this work was to study the effects of different nitrogen rates (0, 50, 100, 150, 200, and 250 kg of N ha−1) on the agronomic, economic, and environmental aspects of processing tomato grown under conventional management in the Mediterranean area. The results of the two-year trials indicated 200 kg of nitrogen ha−1 as the best rate, ensuring the highest values of marketable and total yields, brix ton ha−1, and marginal net return and the lowest global warming potential per ton of marketable yield. However, since plants fertilized with 200 kg of N ha−1 did not record the highest values of nitrogen use efficiency and nitrogen uptake efficiency, our finding suggest the possibility to select better-performing cultivars for these physiological parameters by adopting specific tomato breeding programs.

“…Inappropriate N administration can reduce crop production and NUE, resulting in increased fertilizer losses and in reduced tomato crop sustainability [46][47][48][49][50][51][52][53][54][55][56][57][58]. NUE is a complex physiological parameter depending on plant genetic background and affected by environmental factors.…”

“…The increase in nitrogen dose decreased the agronomical efficiency, physiological efficiency, apparent recovery and nutrient use efficiency may be because of comparatively low uptake and low grain yield and biological yield this fact can be explained by law of diminishing return. Similar results have been reported by Tedone et al (2014).…”

An experiment was conducted at CCS Haryana Agricultural University, Hisar during rabi 2010-11 and 2011-12, consisting of three irrigation frequencies viz. one irrigation at CRI, two irrigations at CRI and heading and four irrigations at CRI, late tillering, heading and milking in main plots and five nitrogen levels (0, 50, 100, 150 and 200 kg N/ha) in sub-plots in strip plot design with four replications. Grain yield and NUE increased significantly with increased irrigation levels. Increase irrigation frequency increased the N (33.4 and 31.3 %), P (42.2 and 42.3 %) and K (26.7 and 25.1 %) uptake over one irrigation during 2010-11 and N (16.0 and 15.9 %), P (19.4 and 20.7 %) and K (11.2 and 13.5 %) during 2011-12. Increased nitrogen dose increased the protein content, hectolitre weight, sedimentation value and grain yield over control. Maximum and minimum nutrient uptake was recorded with 200 and 0 kg N/ha.

“…Durum wheat is widely cultivated in the Mediterranean, under rainfed conditions using conventional tillage (CT) and high input of synthetic N fertilizers. In Italy, durum wheat is important for the economy by providing the semolina to produce pasta, being Italy the largest supplier and exporter in the world [1]. Since more than two thirds of durum wheat production comes from the Italian southern regions [2], cropping strategies that optimize input use and increase the efficiency of fertilizers must be developed, especially in the dry regions.…”

A field experiment was conducted in Southern Italy to study the response of durum wheat (Triticum turgidum L. var. durum) grain yield and quality traits to a no-tillage (NT) system and different nitrogen N fertilizer rates (30, 60, and 90 kg N ha −1 ). The NT system was evaluated and compared to conventional (CT) and reduced (RT) tillage within continuous wheat (WW) and faba bean-wheat (FW) crop sequences over 3-years (2010-2012). The results showed a promising grain yield increase (30%) in the last year. The effect of the N rate on protein content was significant, while productive parameters were not significantly influenced due to both weather conditions and the previous crop. Tillage effect was significantly (p ≤ 0.05) positive on grain yield, yield components and quality parameters, especially in NT system, and was more pronounced when accompanied with faba bean in the rotation system. Despite producing a lower grain protein content (13%) compared to other systems, NT produced good semolina quality (with higher hectoliter weight and lower percentage of broken and shriveled grains). This study provides useful information for farmers on how to produce a satisfactory yield and good grain quality with minimum inputs, helping to design sustainable strategies for durum wheat cultivation in the dry regions.
