“…N up increased with a greater soil N availability and the corresponding increase in the yield, as observed on numerous species including wild rocket [48,74,75]. The NUE, on the other hand, was higher with the lowest nitrogen rate, as previously reported on wild rocket [42,48] as well as on other species [76].…”

Wild rocket (Diplotaxis tenuifolia L. DC) is an emerging vegetable which market requires high-quality standards that can be obtained through appropriate cultivation techniques such as the right level of nitrogen and the application of biostimulant substances. These include strobilurins, marketed mainly as fungicides that can have complementary positive effects on the yield, quality and resources’ use efficiency of many crops. For this reason, a trial in an unheated greenhouse, in Southern Italy, to evaluate the possibility of using Azoxystrobin to improve the production of wild rocket subjected to different nitrogen inputs, was carried out. Two N levels (40 and 140 kg ha−1), Azoxystrobin-based biostimulant (Azo+) and control without Azoxystrobin (Azo−) were compared. The yield, morphological characteristics, nitrogen and water use efficiency (NUE, WUE), antioxidant activity, the content of dry matter, chlorophyll, carotenoids, phenols, and nitrates were assessed. A higher N level resulted in a 16.3% yield increase that was matched by a 12.5% reduction in NUE, 15.8, 7.3, and 16.1% increases in yield WUE (Y_WUE), biomass WUE (B_WUE), and irrigation yield WUE (IY_WUE), respectively, and a worsening of some qualitative characteristics such as a 8.5% rise in nitrates, and a decline by 11.5, 10.1, and 26.1% in the carotenoids, phenols, and antioxidant activity, respectively. Azo+ increased the yield by 10.3%, NUE by 8.9%, and Y_WUE, B_WUE, and IY_WUE, by 13.9, 9.1, and 13.8% respectively. Moreover, Azo+ improved some qualitative characteristics such as total phenols (+9.4%), chlorophyll (+15.2%), carotenoids (+9.7%), and antioxidant activity (+17.4%), while it did not affect the nitrate content. Azoxystrobin can be an additional tool available for farmers to ensure high-quality standards of wild rocket.

“…The result corroborates the claim that crop management is an important factor in the quality of vegetables, especially related to nitrate accumulation (LIU et al, 2014;STAGNARI;GALIENI;PISANTE, 2015;AHMED et al, 2017). N rate is one of the main factors that promotes higher accumulation of nitrate (MAYNARD et al, 1976;CEYLAN et al, 2002). Higher solar radiation and temperature present in summer growing (Table 1) favoured lower N accumulation than in autumn cultivation.…”

Nitrogen is the second nutrient most demanded by arugula. However, the positive effect it has on yield can negatively impact the quality of this vegetable, with negative effects on human health. Two experiments (summer and autumn) were carried out to evaluate the effect of N rates (0, 50, 100, 150, 200 and 250 kg ha−1) on the arugula growth, yield and quality (nitrate content). Each experiment was set up in a randomized block design with four replications. Increasing rates of N reflected positively on leaf N content and thus, higher and desirable values of height, leaf number, leaf area and plant dry mass were obtained in both growing seasons. Consequently, the yield had significant increase, which N was maximized in summer (4.9 kg m−2) and autumn (2.6 kg m−2) and leaf N of 29.4 and 27.0 g kg−1, respectively, at rates of 250 and 213 kg ha−1 and both growing seasons. The higher rate the higher foliar nitrate content of arugula, in summer (2931.3 mg kg−1) and autumn (4218.4 mg kg−1). The foliar nitrate content in both crop season do not reach the risk level to human being heath.
