This study is aimed at examining the usefulness of mugwort as an alternative of western herb by making widely known tomato sauce with mugwort powder added, the ingredient that has a bio-active substance. The control group showed the highest percentage of water from tomato sauce, 89.24%. The sauce with mugwort added in by 2% showed the lowest pH, 4.55. The brightness L value for chromaticity got lower significantly (p>0.001) as the amount of added mugwort increased, and red a value and yellow b value were high in the control group for 18.06 and 16.84 respectively, and got reduced as the amount of added mugwort increased. The salinity was the highest in the sauce mugwort added in by 2% for 1.02. Sugar content and reducing sugar were the lowest in the sauce mugwort added in by 2% for 9.49 and 56.01. As measuring total count change, no microorganism was found until $10^{th}$ day of storage, and was 0% $1.7{\times}10^3CFU/mL$ on the $15^{th}$ day, and no microorganism was found in the 1.5% and 2% added groups. Lastly for 60 days of storage, the control group without mugwort showed the highest microorganism count for $3.1{\times}10^8CFU/mL$ In a sensory test, color was in the 1% added group was 5.28, higher than the control group which showed 4.78, but there was no significant difference. Taste was rated most highly in the 1.5% added group for 5.65. After taste was also rated most highly in the 1.5% added group for 5.8. Overall preference was the highest in the 1% added group for 5.79. From the results, tomato sauce with mugwort added in showed the high storage capacity and was rated highly in the preference test. The possibility of the alternative of western spice and the potential to use Korean spice for other western spice were observed again.

As an essential means to the exploitation of new demands, the export of agri-food has the price-supporting effect on the domestic agri-food and its expansion can be a good way to increase farms' income. Of course, to enhance farms' income under the liberalization of the market, it is necessary to have countermeasures considering various factors. To this end, the study understood the experiences of farms doing exports and looked into ways to improve them by reviewing their motivations to export, difficulties, requirements, etc. In this context, the study conducted the purposive sampling among tomato export farmhouses in Jeongseon-gun in the export enforcement phase and executed the theme analysis. The research findings and suggestions are as follows. First, in order to enhance the level of commercialization of Jeongseon-gun tomatoes and reinforce the trade bargaining power, it is necessary to form the consensus on policy and make the scaling of the site based on the strong organization power. To this end, it requires the active role of agricultural cooperatives that take a big portion of distribution in the site and distribute its profits directly to farmhouses. Second, it is necessary to set clear target markets for Jeongseon-gun tomato export farms and set sales strategies for each target market. That is, in order to expand the export of Jeongseon-gun tomatoes, after clarifying local sales and export sales, export farmhouses should focus on quality management and secure the quantity for export. Third, to expand the export to Japan which already has the foundation for the export of Korean tomatoes, and to new export countries of China, Russia, etc., it is necessary to set the 'Two-Track Strategies for Export Market (particular item for focus and particular area for focus)' through the building of network of tomato export areas in Gangwon-do. In conclusion, to expand the export of Jeongseon-gun tomatoes, agricultural cooperatives and leaders together should build the strong organizational power with farmhouses and secure the quantities for export. And, according to the 'Two-Track Strategies for Export Market (particular item for focus and particular area for focus)', export infrastructure and export operational system should be built and to do so, the solidarity of tomato export farmhouses in Gangwon area should precede.

This study was carried out to investigate the effect of the concentration of nutrient solution on growth of tomato(Lrcopersicon esculentum Mill. cv. seokwang) in substrate culture. The substrates used in the experiment were perlite, vermiculite, and peatmoss. Tomato plants were treated with different concentrations of nutrient solution, viz. 0.5, 1.0, 2.0, 3.0, and 5.0mS/cm at seedling stage and transferred to different treatments, 1.0, 2.0, and 3.0mS/cm after transplanting in each substrate. Total fruit number, total yield, marketable fruit number, and marketable yield were much higher at 2.0-3.0mS/cm than at 1.0mS/cm in all three substrate culture. The percentage of malformed fruit was in order of peatmoss>perlite> vermiculite and Vitamin C content was vermiculite> perlite> peatmoss. In all three substrate culture, high marketable yield was shown when tomato plants grew with concentration of 2.0-5.0mS/cm at seedling stage and 2.0-3.0mS/cm after transplanting. The concentrations of nutrient solution after transplanting as well as at seedling stage had a great influence on total yield, marketable yield, and soluble solids. However total and marketable fruit number were considerably affected by the concentrations of nutrient solution after transplanting.

The investigation of the effect of the deep sea water in different concentration (0%, 10%, 20%, 30%, 40%) on the inhibition of growth, fresh weight, dry weight of the tomato, hot pepper, cucumber plug seedlings were conducted. As the concentration of the deep sea water was higher, the greater inhibition was noticed. The height were decreased at the rate of 8%, 25%, 32% in tomato, 9%, 26%, 27% in hot pepper, and 21%, 50%, 58% in cucumber plug seedlings as compare to local check. The fresh weights were decreased highly, as the concentration of the deep sea water increased. Tomato seedlings showed the decrease rate of 12%, 23%, 33% at above the ground part of plants, and 2%, 30%, 52% at under the ground parts. Likewise, Hot pepper seedlings showed the decrease rate of 1.1%, 5.7%, 15.4% at above the ground part of plants, and 22.1%, 25%, 47.1%, respectively at under the ground parts. The fresh weight of cucumber was decreased at the rate of 8.1%, 36%, 51% in the above the ground, and 6.2%, 11%, 65% at the under the ground parts. In tomato, hot pepper, and cucumber seedlings, the dry weight was decreased as the concentration of deep sea water was increased. Thirty percent of deep sea water treatment reduced the dry weight of the seedlings as half of the control seedlings. One of the important factors of the seedling quality is compactness. Compactness was highest at 20% deep sea water in all the three crop seedlings.

Overhead and sub-irrigation of deep sea water to tomato seedlings reduced the height as 50% and 58% than control plants. In the same treatment with surface sea water and NaCl water, the reduced rate in tomato seedlings' height were 49% and 56% in overhead irrigation, and 47% and 57% in sub-irrigation, respectively. Most effective method for the inhibition of the growth of the seedling was sub-irrigation method, which supplied water through the roots. No significant difference was observed on fresh weight of the upper part of tomato and cucumber seedlings, though the sub-irrigation reduced the fresh weight than the overhead irrigation. The reduced rate of fresh weight of seedlings by overhead irrigation was by 38% and sub-irrigation by 49% as compared to control. Similarly dry weight of upper and under soil parts of seedlings showed same trend of results thereof as fresh weight. This result can be traced to reduction of growth caused by salts in the water. In stem diameter of seedlings no significant difference was observed between two irrigation methods, even though both deep sea and NaCl water reduced stem diameter, as compared to control water. Overhead irrigation can be chosen by seedling producers because of better seedling quality by using TH ratio. Seedling compactness were not noticed in both the overhead and sub-irrigation. Sub-irrigation was found more effective method far the inhibition of height and compactness of tomato seedlings. Higher the concentration of NaCl, deep sea, and surface sea water, lesser the growth in height, fresh and dry weight, stem diameter, and leaf area was obtained. No significant difference was found, though sub-irrigation suppress the growth of seedlings.

This study was conducted to investigate the physicochemical and quality characteristics of alcohol fermentation of tomato. For yeast, Saccharomyces bayanus Lalvin EC-1118 displayed the highest alcohol content (11.8%), whereas titratable acidity and pH did not differ significantly between different yeasts. Alcohol fermentation conducted at higher temperature ($25^{\circ}C$) resulted in higher alcohol content and lower sugar level. The highest alcohol content was produced using 11.4% sucrose and 11.1% fructo-oligosaccharide. These two saccharides were suitable for tomato alcohol fermentation. Lycopene levels were similar regardless of sugar type, and were approximately 4.2 mg%. To improve lycopene content, three types of fruit wine with low-dose lycopene (LDL), medium-dose lycopene (MDL), and high-dose lycopene (HDL) were made. Their alcohol contents were not significantly different (10.0~10.8%). Lycopene contents of LDL, MDL, and HDL wine were 4.25 mg%, 11.40 mg%, and 20.45 mg%, respectively. Therefore, HDL tomato wine should be manufactured.

This study was conducted to enhance graft-take ratio and quality of grafted tomato seedlings by controlling temperature and humidity during the healing and acclimatization processes. Three temperature levels ($20^{\circ}C$, $23^{\circ}C$, and $26^{\circ}C$) were carried out to determine optimum temperature on four rootstocks. In addition, twelve combinations of three relative humidity levels (70%, 80%, and 90%) and four temperature levels ($17^{\circ}C$, $20^{\circ}C$, $23^{\circ}C$, and $26^{\circ}C$) were set up to evaluate the effect of relative humidity and temperature on the graft-take ratio of grafted seedlings. In the other hand, five relative humidity periods (H0, H1, H2, H3, and H4: 90% relative humidity for first 0, 1, 2, 3 and 10 days and afterwards relative humidity was reduced to 70%, respectively) were examined effect of relative humidity periods on the graft-take and quality of grafted seedlings. The higher graft-take ratios (84.0~87.4%) were showed at $23^{\circ}C$ compared to $20^{\circ}C$ and $26^{\circ}C$ in all rootstocks. Graft-take ratios decreased and number of diseased plants increased at high temperature. The graft-take ratios increased with increasing relative humidity in all temperature levels on the $3^{rd}$ and $7^{th}$ day after grafting. However, increasing relative humidity significantly increased percent of diseased plants. The graft-take ratio reduced at ($26^{\circ}C$) and ($17^{\circ}C$) temperature under all relative humidity conditions. The graft-take ratio increased with increasing period of 90% relative humidity. Maximum graft-take ratios were observed in H2 and H3 treatments. Graft-take ratio decreased with increasing 90% relative humidity for 10 days (H4). Diseased plants had not been found in H0, H1, H2, and H3 treatments. Seedling quality was improved through increasing fresh and dry weight of root, compactness, and root morphology of tomato seedlings in H2 and H3 treatments. Therefore, high relative humidity (90%) for first 2 or 3 days and afterwards reduced low relative humidity (70%) at $23^{\circ}C$ condition during healing and acclimatization promoted the graft-take and quality of grafted tomato seedlings.

This research was conducted to know the appropriate leaf number of scion for tube grafting in context with survival rate and quality of seedlings, and early yield of $1^{st}$ and $2^{nd}$ cluster of cherry tomato plants. Scions were grafted when having leaves 1~2 (LF-2), 2~3 (LF-3), or 3~4 (LF-4). The treatment LF-3 showed the highest survival rates and the best results in 6 factors among 12 seedling quality factors. In case of early yield, the treatment LF-2 showed higher yield than others with the big difference. Economic analysis showed that LF-3 is desirable in case of nursery while LF-2 is better in case of farmers. The compromising solution is that farmers buy a little expensive seedlings grafted at the leaf stage of 1~2 from nurseries in terms of win/win strategy.

We studied the residual patterns of two fungicides, dichlofluanid and iprodione, in cherry tomato greenhouse after applying with the recommended and double dose. Also, the degradation patterns during storage periods of up to ten days were compared between at room temperature (20$^{\circ}C$) and at cold temperature (4$^{\circ}C$). Removal rates of fungicides by washing with tap-water and detergent solution (0.1%, 0.2%) were measured. Half-lives of dichlofluanid and iprodione in greenhouse cherrytomato were 2.2$\sim$3.5 and 3.3$\sim$5.4 days, respectively. During the storage period, the residues were dissipated more slow. Removal rates were 62.8$\sim$80.3% by tap-water, 60.4$\sim$83.1% by 0.1% detergent solution, and 65.3$\sim$77.6% by 0.2% detergent solution. So, we can predict of terminal residues from cultivation period to marketing, storage and consuming.

The present paper reviews the findings of different research studies on the effect of natural ingredients in the Japanese quail (Coturnix coturnix japonica) diet on carcass characteristics and meat quality. The results show a relationship between the type and concentration of ingredients used in diets and carcass characteristics and meat quality. The inclusion of medicinal herbs (thyme, black seed, and mint), plants (canola), seeds (chickpea), spices (cinnamon and coriander), worms (earthworms), bee products (propolis), phytochemicals (lycopene), and edible fungi (common mushrooms) in the diet improved carcass quality characteristics compared to the control diets (basal diets). The inclusion of medicinal herbs (spearmint and green tea), spices (cinnamon), vegetables (tomato), plants (verbena and canola), seeds (marijuana), and edible fungi (oyster mushrooms) improved meat quality. In conclusion, the use of ingredients of natural origin in the diet of Japanese quail improves carcass quality characteristics and meat quality.
