“…The effect of nitrogen treatments on the yield of tomato fruits was not consistent between the years, and environmental factors may have been the main reason for the lack of this consistency across years. A review reported that the effects of recommended nitrogen rates for tomato fruits varied significantly depending on experimental purposes and environmental factors [ 42 ], an observation that is in agreement with our findings. Plants grown in Year 1 exhibited a higher yield compared with Year 2.…”

“…Arias et al [ 40 ] and Akbudak et al [ 41 ] found positive correlations between a* (red hue) and the lycopene content of tomato fruits at different ripening stages. A positive effect of nitrogen fertilization on the red colour of tomato fruit, related to the increment of lycopene concentration, has also been recorded [ 40 , 42 ]. Applications of nitrogen levels five times above the standard dose increased the colour index a* compared to standard and unfertilized treatments [ 37 ].…”

Tomatoes (Solanum lycopersicum L.) of the variety Elpida were grown under standard Mediterranean greenhouse conditions during the spring season at three different nitrogen levels (low 6.4, standard 12.8, high 25.9 mM/plant), which were replicated during two consecutive years. Application of high nitrogen significantly increased the colour index a* (p < 0.001) but did not significantly affect yield or quality. The variety exhibited prolonged postharvest storage at room temperature (median survival time of 93 days). The maturation process was delayed by harvest at the breaker stage (2.5 days, p ≤ 0.001) or by super-optimal temperatures in the second year of experimentation (10 days, p ≤ 0.001). The colour indices L* and a* and the hue angle (a/b*) were positively correlated with the sum of total carotenoids, while differences in b* depended on the year of cultivation. The sustainability of this type of tomato production can be improved by reducing the nitrogen supply to less than the current standard practice, with minimal risk or negative effects on yield and quality of tomatoes.

“…Therefore, the application of 5% or 10% CT will introduce massive amounts of various elements to the soil and plants [e.g., 5% CT application rate (tonnes ha −1 ): C, 13-27; K, 1; N, 0.4-0.6; P, 0.05; Ca, 0.4; and Mg, 0.5). The supplements of 5% CT in our study were higher than the required nutrients for plants and higher than the supplements applied in many other studies, except P (Ward 1964;Kanai et al 2011;Cheng et al 2021). Surprisingly, our results indicated that these nutrients in tomato leaves only slightly increased with 5% CT treatments and significantly increased with 10% treatments.…”

Coal tailings as a soil conditioner: evaluation of tailing properties and effect on tomato plants

et al. 2022

The global coal industry yields a vast amount of tailings waste, and the utilisation of these tailings necessitates innovative efforts contributing to the United Nations Sustainable Development Goals. One of such novel initiatives is to reuse coal tailings (CT) safely, ecofriendly, and cost-effectively in agroecosystems as a soil conditioner to enhance the productivity of lands. This study aimed to evaluate the potential utilisation of coal tailings waste in the soil amelioration to improve plant performance. The physico–chemical characteristics of coal tailings from two Australian mining sites (CT1 and CT2) showed that the tailings samples are alkaline with loamy and loamy sand textures, respectively. The tailings have ~ 3% of macronutrients, high carbon (C), and low heavy metals and metalloids (As, Cd, Se, Cu, Zn, and Pb). The germination rate of tomato seeds was improved in the low-rate CT treatment. Greenhouse tomato plants exhibited an increase in leaf’s K, Ca, and Mg contents in CT1 and CT2 treatments. More importantly, the CT treatment-induced accumulation of heavy metals in plants was mostly insignificant in both CT treatments. Therefore, we highlight the potential application of coal tailings as a soil conditioner because of the beneficial effect of improved carbon and nutrients (N, P, K, Mg, and Ca) in tomato leaves. Further amendment of the coal tailings should focus on the adjustment of pH and the addition of other beneficial materials for the improvement of soil properties for crops in both the greenhouse and the field.

“…Tomato ( Solanum lycopersicum ) is a highly demanding vegetable in terms of N and water supplies ( Zotarelli et al, 2009 ; Ayankojo et al, 2020 ) with an estimated uptake ranging from 200 to 400 kg N/ha based on pedological conditions ( Zhang et al, 2011 ; Cheng et al, 2021 ), and a daily uptake of up to 1.8 L plant –1 , depending on solar radiation and temperature ( Hanping et al, 2017 ). In the past two decades, the global production grew from 109⋅10 6 tons in 2,000 to 186⋅10 6 tons in 2020 ( FAOSTAT, 2021 ), on a total surface that increased by 31% in the same period, up to 5 million hectares, which represents, to date, the largest world cultivation area among vegetables.…”

The agricultural scenario of the upcoming decades will face major challenges for the increased and sustainable agricultural production and the optimization of the efficiency of water and fertilizer inputs. Considering the current and foreseen water scarcity in several marginal and arid areas and the need for a more sustainable farming production, the selection and development of cultivars suitable to grow under low-input conditions is an urgent need. In this study, we assayed 42 tomato genotypes for thirty-two morpho-physiological and agronomic traits related to plant, fruit, and root characteristics under standard (control) and no-nitrogen fertilization or water deficit (30% of the amount given to non-stressed trials) treatments in two sites (environments), which corresponded to organic farms located in Italy and Spain. A broad range of variation was found for all traits, with significant differences between the applied treatments and the cultivation sites. Dissection of genotypic (G), environmental (E), and treatment (T) factors revealed that the three main factors were highly significant for many traits, although G was the main source of variation in most cases. G × E interactions were also important, while G × T and E × T were less relevant. Only fruit weight and blossom end rot were highly significant for the triple interaction (G × E × T). Reduction of water supply significantly increased the soluble solid content in both locations, whereas both nitrogen and water stress led to a general decrease in fruit weight and total yield. Despite so, several accessions exhibited better performances than the control when cultivated under stress. Among the accessions evaluated, hybrids were promising in terms of yield performance, while overall landraces and heirlooms exhibited a better quality. This suggests the possibility of exploiting both the variation within ancient varieties and the heterosis for yield of hybrids to select and breed new varieties with better adaptation to organic farming conditions, both under optimal and suboptimal conditions. The results shed light on the strategies to develop novel varieties for organic farming, giving hints into the management of inputs to adopt for a more sustainable tomato cultivation.
