Effect of ammonium and nitrate ratios (0:100, 25:75, 50:50 and 75:25) on nutritional quality of flowering Chinese cabbage (Brassica campestris L. ssp. chinensis var. utilis Tsen et Lee) with 3 cultivars were studied in hydroponics. The results indicated that, with the increasing of ammonium proportion in nutrient solution, the soluble sugar content in product organ of flowering Chinese cabbage increased gradually, but Vc content decreased gradually. Enhancement of ammonium by 25% or 50% in nutrient solution increased the soluble protein content in leaf significantly, while it increased gradually in stalk with the increasing of ammonium proportion. Free amino acids in product organ of flowering Chinese cabbage were improved significantly by enhancement of ammonium in nutrient solution. Integrated nutritional quality of flowering Chinese cabbage in 25% ammonium enhancement treatment was better than others under hydroponics condition.

Spinach is a leafy vegetable containing a plethora of bioactive compounds. Our study aimed to evaluate the physiological (i.e., JIP-test) and phytochemical response of spinach baby leaves grown with regular or mildly saline (40 mM NaCl) nutrient solution and irradiated by four light-emitting diodes (LEDs) with broad spectra. T1 (highest red and far-red, low blue) and T3 (high red, balanced blue, green and far-red) led to a better developed photosynthetic apparatus compared to T2 (red peak in 631 nm) and T4 (highest blue and green), highlighted by PIABS and its structural components: RC/ABS, φP0, ψE0, and ΔVIP. Elevated salinity only affected the latter parameter. T1 induced the maximum yield production but also the highest nitrate content which was far below the maximum level permitted by European legislation. Regardless of salinity level, T3 enhanced total phenol, chlorophyll, and carotenoid content. T2 and T4 led to inferior nutritional quality. Non-saline nutrient solution promoted the chlorophyll and carotenoid contents and the antioxidant potential, regardless of light treatment. By contrast, soluble sugar content was enhanced by saline nutrient solution. Our study shows that physiology and nutritional quality of spinach baby leaves can be manipulated by small interplays in the light spectra and salinity level.

The interacted effects of photoperiod and nutrient solution concentrations (NSCs) on nutritional quality and antioxidant and mineral content in lettuce were investigated in this study. There were a total of nine treatments by three photoperiods (12 h/12 h, 15 h/9 h, and 18 h/6 h), with a combination of three NSCs (1/4, 1/2, and 3/4 NSC). The contents of photosynthetic pigment, mineral element, and nutritional quality were markedly affected by the combination of photoperiod and NSC. The highest leaf number and plant weight were found in lettuce under the combination of 18–0.25X. There was a higher content of photosynthetic pigment in treatment of 15-0.25X. Shorter photoperiod (12 h/12 h and 15 h/9 h) and NSC (1/4 and 1/2 NSC) contributed to reduced nitrate contents and higher contents of free amino acid, soluble protein, and vitamin C. Longer photoperiod and lower NSC could increase soluble sugar content. The content of total P, K, and Ca exhibited a similar trend under the combination of photoperiod and NSC, with a higher content at 3/4 NSC under different photoperiods. Lower contents of total Zn and N were found under longer photoperiod. Moreover, higher antioxidant contents, including 2, 2-diphenyl-1-picrylhydrazyl (DPPH), value of ferric-reducing antioxidant power (FRAP), flavonoid, polyphenol, and anthocyanin were observed under shorter photoperiod, with the peak under 12-0.50X. Generally, 12-0.50X might be the optimal treatment for the improvement of the nutritional quality of lettuce in a plant factory that produced high-quality vegetables.

Vegetables form major part of human dietary/nutritional needs. It provides the necessary vitamins and minerals as well as antioxidants to boost immunity. Different vegetables however have different benefits and require different growing conditions. This study investigated the effect of two growing conditions (Screen-house and open field) and soil amendments; Mexican sunflower compost (MSC; applied at 0, 5, 10 t/ha) and NPK 15:15:15 (applied at 0, 50 and 100 kg N/ha) on the growth performance, yield, and nutritional quality of five selected vegetables (Amaranthus cruentus, Celosia. argentea, Solanum macrocarpon, Solanum nigrum and Solanum incanum). Each treatment was replicated three times and experiment arranged in completely randomized design, Compost was applied a week before seed sowing vegetables grown in the screen-house generally performed better than the open field in terms of leaf area and chlorophyll content. The response however varied based on the vegetable and the soil amendments. Solanum species, performed better than Amaranthus under screen-house than open field. Chlorophyll in the leaf responded positively to NPK fertilizer under screen-house conditions while growth parameters such as plant height, stem girth, number of leaves under screen-house and field conditions varied depending on the vegetables. The number of leaves and leaf area increased with soil amendments. Moisture, crude protein and ash contents were reduced under open field compared to screen-house. The zinc and iron contents of the vegetable leaves showed that addition of compost was superior to NPK and screen-house better than open field. It can be concluded that vegetables grown in the screen-house performed better in their respective growth parameters than vegetables are grown under the open field.

Biomass and quality index of Chinese cabbage were investigated under the following treatment, control (CK), 25% biogas slurry + 75% fertilizer (Z-25%), 50% biogas slurry + 50% fertilizer (Z-50%), 75% biogas slurry + 25% fertilizer (Z-75%), and 100% biogas slurry (Z-100%). The results indicated that Z-25% significantly increased shoot height and fresh weight. But shoot height and fresh weight significantly decreased in a time-dependent manner when the concentration of the biogas slurry was greater than 50%. Vitamin C, soluble sugar, protein, and nitrite were measured to evaluate the effect of biogas slurry on the quality of Chinese cabbage. Z-25% treatment could remarkably increased the content of dehydroascorbate (DHA) and total Vc, whereas did not significantly affect reduced ascorbate (AsA) content compared to the CK for 60 d. The content soluble sugar and protein were significantly enhanced under Z-25% treatment. In addition, Z-25% effectively reduced nitrite content in Chinese cabbage. Biogas slurry with concentration more than 50% could not promote quality index of Chinese cabbage. To sum up, biogas slurry of water hyacinth could improve the growth and quality of Chinese cabbage under the optimal applied concentration.

Nitrogen plays a vital role in the growth, development and nutritional quality of Chinese chive, which is an important leafy vegetable. The effects of improved Hoagland nutrient solutions on the nutritional quality and physiological characteristics of three Chinese chive cultivars (Saisong, Pingjiu No. 4 and Pingjiu No. 8) were investigated by modulating the ratio of nitrite nitrogen (NO<sub>3</sub><sup>&ndash;</sup>-N) to ammonia nitrogen (NH<sub>4</sub><sup>+</sup>-N). Improved Hoagland nutrient solutions with NO<sub>3</sub><sup>&ndash;</sup>-N to NH<sub>4</sub><sup>+</sup>-N ratios of 50:50 and 75:25 could effectively promote the accumulation of soluble protein, soluble sugar, vitamin C and proline; decrease the malondialdehyde content; and induce the superoxide dismutase and peroxidase activities of the three cultivars. It is strongly suggested that NO<sub>3</sub><sup>&ndash;</sup>-N to NH<sub>4</sub><sup>+</sup>-N ratios of 50:50 and 75:25 improve nutritional quality and promote growth and are thus suitable for Chinese chive growth under hydroponic culture.

Nitrates Content

The evaluation of nutritional quality of Chinese cabbage and the effects of cultivar, weed incidence, plant density and growing season were observed in integrated cultivation system. Mean contents of analysed compounds were as follows: 6% of dry matter, 10% of crude fibre, (in mg/kg of f.m.): 2,199 mg K, 289 mg Ca, 146 mg Mg, 111 mg Na, and 316 mg of vitamin C. Mean content of nitrates reached the value of 647 mg/kg. A significant effect of cultivar on the content of all observed substances in cabbage heads excluding magnesium was thus confirmed; however, a decrease of nitrates was found in the treatment with higher plant density. Weed cultivation caused slightly (insignificantly) higher nitrates content in cabbage heads by 100 mg/kg. Growing season showed a significant effect on content of some evaluated compounds. Integrated cultivation of Chinese cabbage could be an adequate approach to ensure nutritionally valuable products with low nitrates content.
