“…Benefits of green manuring can be increased with additional use of organic, biological, or other fertilizers [31][32]. Green manure and biological fertilizers improve soil structure, increase water-holding capacity, and enhance microbial activity in the soil, reduce chemical residues, increase environmental sustainability, and create a basis for the increase of crops antioxidant activity [33][34][35][36].…”

Background: Green manure fertilizers play a great role in increasing fertility, soil quality and nutrient supply of crops. Additionally, biofertilizers with various strains of fungi increase the availability of biologically active elements for plants. The combined use of green manure and biological fertilizers is of great interest for increasing the content of bioactive components and the functional activity of food.Objective: The main goal of the research was to evaluate the effectiveness of the combined use of various green manure plants and biological fertilizers on the content of bioactive components (total sugars, dry matter, ascorbic acid, B vitamins and macro and micronutrients) in eggplants in the context of increasing food functionality. Methods: Plants from the Fabaceae L. family (beans, peas, and soybeans) were used as green manure. The experiment was set up by a block-randomized method in 4 replications. Biofertilizers were applied at the beginning of intensive growth and at the beginning of the fruiting stage. Soil analysis and content of macro- and micronutrients (Potassium, Calcium, Magnesium, Phosphate, and Iron) in eggplant fruits were done with a spectrophotometry system. Results: Green manure crops and their combination with biofertilizers contributed to an increase in content of vitamin C, Vitamin B1, macro-micronutrients (calcium, potassium, phosphorus, magnesium, and Iron) in all treatment options. The higher yield was recorded in variants with the use of Organit N’ and ‘Organit P’.Conclusion: The concurrent application of green manure and biofertilizers leads to an enhancement of the functional properties of eggplant fruits. This improvement is attributed to the enhanced soil quality and increased levels of nutrients and bioactive compounds, including vitamins C and B1.The positive effect of the applied technology on the eggplant fruits’ qualitative particularities, productivity and functionality creates a basis for recommending the use of tested fertilizers to producers and will serve as a starting point for evaluating the proposed green technology on other crops.Keywords: soya, bean, pea, vitamin C, vitamin B 1

Codonopsis lanceolata (S. et Z.) Trautv. is mainly cultivated in Korea and China as a medicinal crop. C. lanceolata is difficult to produce plug seedlings in the summer, because C. lanceolata has a low germination rate and is vulnerable to high temperatures. Cold treatment is effective in breaking dormancy of seeds and increasing the germination rate. Shading cultivation can control the solar irradiance received by plants and reduce the damage by high temperatures and strong light. This study was conducted to examine the appropriate cold treatment period for the improving germination of C. lanceolata, and shading level during the summer seedling period. Cold treatment experiments were conducted for 0 (control), 1, 2, 3, and 4 weeks at 4°C before sowing. In the shading experiment, C. lanceolata was grown for 45 days with 0 (non-treatment), 45, 75% shading levels. Cold treatment for one week significantly improved the germination energy. The plant height, leaf area, and fresh and dry weights of C. lanceolata seedlings were significantly increased under the 45% shading level. Total root length, root surface area, and the number of root tips were significantly higher in shading treatment (45 and 75%) than in non-treatment. The C. lanceolata seedling's compactness and Dickson's quality index were the highest at 45% shading level. Therefore, these results recommended sowing C. lanceolata after cold treatment for one week at 4°C, and 45% shading level could stably culture C. lanceolata plug seedlings during the high temperature period.

Codonopsis lanceolata, called deodeok in Korean, has been verified for various effects, including anti-aging and antiinflammatory effects and insomnia improvement, and is one of the healthy foods that Koreans enjoy eating. In this study, the saponin content, lansemaside A content, and total saponin content of deodeok were analyzed using high-pressure sterilization and solid fermentation by mixed lactic acid bacteria. The antioxidant effect was compared to determine improved processing methods of deodeok. The lansemaside A content of deodeok samples depending on the preprocessing methods was analyzed: 2,594.10 mg/kg for dried deodeok, 2,100.93 mg/kg for steamed deodeok, and 1,151.31mg/kg for fermented deodeok. The total saponin content was found to be 7,209 mg/kg for dried deodeok and 8,605 mg/kg for steamed deodeok, showing a high saponin content. The total polyphenol content was highest for dried deodeok, steamed deodeok, and fermented deodeok. As for the antioxidant effect, it was analyzed that the effect of dried deodeok was the highest, followed by steamed deodeok and fermented deodeok; Dried deodeok had the highest value in total polyphenol content, not in total saponin content, which is considered to have a positive influence on its antioxidant effect. The content of lansemaside A was the highest for dried deodeok. When fermented deodeok is consumed, more beneficial effects on health can be expected by ingesting it with lactic acid bacteria cultured using saponins and polyphenols. Therefore, this study suggests the possibility of manufacturing products suitable for the needs of consumers, such as the flavor of deodeok, according to the processing methods.
