\u3000This result suggests that even if the bagged fertilizer is placed where it is not in direct contact with the string, the roots will grow in response to the solution concentration and the above-ground parts will grow normally. Therefore, we investigated the growth, yield, and leaching of fertilizer nutrients by placing bagged fertilizers \"on the string,\" \"next to the string,\" and \"under the seedlings\" at planting time. In addition, we investigated whether placing the bags on the opposite side of the aisle from the string insertion slot is reasonable in terms of cultivation management (Figure 4, see photo), and whether this would cause problems with fruit growth and quality.<\/p>\n\n\n

\u3000Even if the fertilizer bags can be removed at the end of harvest, the treatment alone does not ensure stable fruit production in successive cropping. In particular, disinfection of the culture medium is necessary for continuous cropping of melons, and solar disinfection has been used for the past four years to avoid soil diseases.<\/p>\n\n\n\n

\u3000Although the bag treatment of this method should also have resulted in a non-uniform solution concentration and partially high EC values, no differences in yield, fruit acidity, or incidence of greenback fruit occurred, probably because the monovalent ion K is absorbed selectively and efficiently.<\/p>\n\n\n\n

\u3000The above results indicate that the fertilizer bag does not need to be placed \"on the string,\" and that there is no difference in yield or quality whether the bag is placed \"next to the string\" or \"under the seedlings,\" suggesting that it does not matter where the bag is placed within a limited growing container. The results also strongly suggest that the planting hole treatment of fertilizer with regulated fertilizer, which has been reported for many crops, can be applied to tomatoes as well.<\/p>\n\n\n\n

\u3000The root division method described at the beginning of this paper and the questions posed in this Arabidopsis experiment suggest that the nutrient-sensing capacity of plant roots is extremely high and that fertilizer does not need to be mixed in homogeneously. It is evident that the information of excess or deficiency of nutrients is transmitted to each root via the above-ground portion to ensure the survival of the plant as an individual. Although some nutrients leached from the bag remained in the medium, the EC value did not exceed 0.4 at a sand:water ratio of 1:2. This is close to the value obtained when growing vegetable seedlings, and will not be a problem in the next crop. After harvest, the fertilizer bag taken out of the medium is placed in a bucket, and the fertilizer that is dissolved in water can be used as a culture solution for other vegetable seedlings.<\/p>\n\n\n\n

\u3000In addition, oidium as an above-ground disease and oidium whitefly and spider fly as insects are problematic, but the greenhouse temperature can reach 55\u00b0C or higher when the greenhouse is sealed, and these diseases and insects can be strongly controlled as long as no external invasion is allowed after disinfection. Thus, solar disinfection of greenhouses is an indispensable technology for the stable production of tomatoes and melons in this method.<\/p>\n\n\n\n

\u3000The \"yam\" is a brand-name agricultural product of Hyogo Prefecture, grown mainly in the Tanba region of Hyogo Prefecture since ancient times.
\u3000It is said that cultivation began in this area in the early Edo period. Because Tamba City is a basin surrounded by mountains, there is a large temperature difference between day and night from fall to winter, and deep morning fog occurs. The \"yama-no-imo\" grown here is also called \"kiri-imo\" (sweet potato grown in the mist).<\/p>\n\n\n

\u3000The \"yam\" does not grow wild like the yam, but is a cultivated crop. Soil conditions are important for the growth of yam, and the soil in the Tamba region is considered suitable for this purpose. The \"yam\" of the Tamba region is sticky, and when grated, its stickiness is much stronger than that of other types of potatoes.<\/p>\n\n\n\n

\u3000Slow-release fertilizer \"CDU Kasei S555\" is used for \"yam\" cultivation by JA Tamba Hikami.
