The key point is the key point or important point of something. A collection of lectures by the late management giant Kazuo Inamori comes to mind. In his later years, he talked a lot about Buddhism, which may be a little off-topic for people looking for the essentials of management. However, there are many hints here and there. He says that managers need a philosophy. It seems that you need a strong will to want to be like this. If you think it should be this way or have that kind of strength, it will break. To this end, he says that starting from an altruistic and humanly correct axis, rather than from a selfish axis, is a necessary condition for having a long-lasting and strong heart. Mr. Inamori founded Kyocera and KDDI and grew them into large companies worth over 1.5 trillion yen and 4.9 trillion yen, respectively. When he became chairman of bankrupt JAL, he led it to re-listing in just two years and eight months. His accomplishments don't stop there. In addition to serving as the president of Seiwa Coaching school, a study group for small and medium-sized business owners, he also founded the Kyoto Prize, an international award originating from Japan, and was instrumental in honoring people who have made great contributions to human society.

The Yumepirika Rice Contest has been held since 2015. The production areas (regional gold medals) that have won the seven regional preliminaries in advance advance to the final judging panel, where the “best gold medal” is decided. The 2022 judging was very close as in previous years, but JA Youtei (Rankoshi area) was selected. The Yumepirika rice, which won the Grand Prize, is affixed with the “Supreme Gold Prize Yumepirika Sticker” and is available only in Hokkaido from early December. In addition, it seems that the Hokuren Agricultural Cooperative Federation EC site will also handle 5 kg bags. Yumepirika rice, which won the district gold prize, will be on general sale from February 2023. The “Hokkaido Rice New Brand Formation Council” will hold the “Yumepirika Contest 2022” in Sapporo on November 21st. “JA Youtei (Rankoshi district)” from Shiribeshi district won the highest gold award for Yumepirika rice produced in 2022. In the Shiribesu district, JA Yotei won the highest gold award for the first time in 2018, and it seems that it is the first time for a single cooperative to win the award for the second time. Shiribeshi is located in the western part of Hokkaido and consists of 20 municipalities. Although it is a name, the Taiho Code (instructed and compiled by Emperor Monmu and completed in 701. It means that a centralized state system centered on the emperor was completed) followed the province-district-neighbourhood administrative divisions (ritsuryo system: Local administrative organization after the Taika Reform. According to the Ritsuryo codes, the whole country was divided into more than 60 provinces, and the provinces were divided into counties, and the counties into village. A village was defined as 50 households, and a county consisted of 2 to 20 ri（1000 / 33 cm ≒ 30.3 cm, about 3.9 km）. The capital sends a provincial governor (under the ritsuryo system, any of a group of officials, esp. the director) to the country, and the county appoints a powerful local family as the district governor (under the ritsuryo system), and the village is there. He selected an influential person from the village and made him the head of the village.) and the end of the Boshin War（In January 1868 (Keio 4 / Meiji 1), starting with the “Battle of Toba-Fushimi”, the “former shogunate army” led by the 15th shogun “Yoshinobu Tokugawa（1837-1913: In 1866, he became the 15th shogun at the age of 29 after the death of the 14th shogun, Iemochi. Even though he became a shogun, he was active mainly in Kyoto instead of Edo and tried to cooperate with influential feudal lords. However, in the following year, 1867, he relinquished his government to the Imperial Court as conflicts with influential domains such as the Satsuma Domain spread and the weakening of the Edo Shogunate became apparent.）” and the Satsuma and Choshu domains. A series of wars fought by the “New Government Army”）. One of the regional divisions enacted soon after, the country’s name is derived from the sound of Shiribeshi, where Abe no Hirafu (575-664) established a county territory, and the Ainu language of the Shiribetsu River flowing through Shiribeshi Province. It is said that the name was given by taking a picture of “Siri Phet” (mountain / river) and transliterating it. The purpose of JA Youtei’s activities was the “International Year of the Potato 2008” (known in Japan as “2008 International Year of the Potato”), which was decided by the United Nations. The story of whether something can be done is brought up by the union president at the time. In addition, it has been decided that the G8 Hokkaido Toyako Summit will be held in July, and an international media center will be established in Rusutsu Village, which is under our jurisdiction. Therefore, 36 varieties of potatoes (for raw consumption, processing, and starch) are cultivated so that they will bloom in early July. The purpose was to improve the image as a production area, to raise interest in potatoes and understanding of agriculture. Kitakamui potato is Globodera rostochiensis (a pest that absorbs nutrients from the roots of potatoes in the soil and greatly reduces the yield. However, it is harmless to humans, but once it occurs in the field, it is completely destroyed. It is difficult to eradicate the disease in the wild, and even in home gardens, if it occurs, it may spread from the field, making it a life-or-death problem for potato farmers. In 1997, at the Hokuren Agricultural Research Institute, “Yellow Shark Potatoes” as mother and “Toya Potatoes” as father. It is a cultivar that was bred from crossbreeding and being tested for seedling individual selection the following year. Since 2004, under the system name “HP01”, it has been tested for the selection of imported potato varieties in Hokkaido, and as a result of examining its practicality as a variety, it was certified as an excellent variety in Hokkaido in 2007. JA Youtei is widely known as Hokkaido’s representative agricultural kingdom, with its fertile land permeated with underground water from Mt. Yotei. Most of the agricultural crops in the entire Hokkaido are harvested, and it seems that it is said to be “a microcosm of Hokkaido agriculture.” It seems that healthy and nutritious vegetables can be grown thanks to the cool climate unique to the highlands, where there is a large difference in temperature, which makes it difficult for pathogenic bacteria to grow, and the farming method that takes advantage of the relatively long hours of sunshine. Among agricultural production, potatoes were designated as a vegetable production area in 1974 at the foot of Mt. Yotei. It has received high praise. Potatoes, which account for one-third of the sales business of 20.2 billion yen, boast a planted area of 3,500 ha and a collection volume of about 80,000 tons, and seem to be the mainstay of JA. In March 1997, the Yotei Agricultural Cooperative Edible Potato Production Organization Liaison Council (there were about 900 producers at the time) was established in March 1997 to unify the activities of the production cooperatives that had been taken over from the former JA after the merger with JA. In order to quickly establish the “Yotei brand”, we are actively developing our business with the aim of standardizing quality at a high level, unifying standards and promoting production. Kutchan is a kanji; Chinese characters for “倶知安”. Kutchan is named after the Ainu word “Kutchani”. Kusshani is the old name of the Kutosan River, a tributary of the Shiribetsu River. Kushani is “Ku Shan Yi” from the meaning of “a place that flows out of a place like a kudzu”. This Ku Shan Yi becomes Kusshani, and further changes to Kudosani to become the Kutoyama River. On the other hand, the same Kusshani became Kuchan and became a place name, which was announced in 1893. The “kanji” was assigned by Takeshi SHIRANI（He has served as the chief of the geography section of the department, the secretary of the Ministry of Education, the secretary of the Takushoku affairs, the secretary of the internal affairs, the chief of the internal affairs secretary / minister’s secretariat Hokkaido, the director of the shrine of the Ministry of Interior and the chief of the Hokkaido section of the general affairs bureau.）, the counselor of the Hokkaido Agency at that time. The town emblem is a design of the acronym “K” of the town with the image of a snowflake and the image of a bird flapping its wings. The overlapping of snowflakes represents “contact”, the image of a fluttering bird represents “leap and dynamism”, and the blue symbol color represents “development and hope for the future”. It symbolizes “Kutchan, the town of contact”. It was enacted on July 1, 1991 to commemorate the 100th anniversary of the opening of the foundation. And this year marks the 130th anniversary. Town Flower: “yellow-flowered rhododendron” – It is an evergreen small shrub that grows naturally in the high mountains of Hokkaido and Tohoku, and has five yellow petals that can be cultivated from July to August. It was selected because it is a representative alpine plant of Mt. Yotei and the Niseko mountain range, and was considered as one of the projects commemorating the 100th anniversary of the opening of the foundation in 1991. Town Tree: Acer pictum Thunb. Subsp. Mono (Maxim.) H. Ohashi, 1993-It is a deciduous tree of the Aceraceae family, and in the fall, seven constricted leaves turn yellow. Selected because it is widely distributed around the town and was used as a material for skis in the early days of skiing. Widely used in parks and roadside trees. It was examined together with Machihana, and was announced and enacted on December 11, 1998. Image character: Jyagata-Kun-The design is for potatoes to ski, with potatoes wearing blue skis and green ski caps. The triangular ski cap is a Sho-chan hat, which was unveiled on August 3, 1991, in the image of Mt. Yotei. “Niseko Town, Abuta District” is 140 degrees 48 minutes east longitude and 42 degrees 52 minutes north latitude. Located in the western part of Central Hokkaido, almost in the center of the Shiribeshi jurisdiction. Surrounded by the mountains of Mt. Yotei (1,898 m), a national park in the east, and Niseko Annupuri (1,309 m), a national park in the north, it forms a hilly basin with many wavy slopes. The Shiribetsu River (the clearest river in Japan in 2004) flows in the center of the town, and small and medium-sized rivers such as the Konbu River, Nisekoanbetsu River, and Makkari River flow into it. It has an inland climate, with an average temperature of 6.3 degrees Celsius, and the deepest snowfall in winter can reach as high as 200 cm. It is within 120 minutes by private car from Sapporo City and Chitose Airport, and about 90 minutes by private car from Otaru City. Niseko means “a steep cliff” in the Ainu language. Also, “Nupuri” means “mountain” in the Ainu language, and the mountain “Niseko Annupuri” with a ski resort means “mountain with a steep cliff (and a river below it)” in the Ainu language. It seems to be. 1895 Entered Nishitomi, the first immigrant of Town. 1897 Separated from Abuta Village and entered the area of Makkari Village. Even as of 1901, the branch village became independent from the neighboring village, Makkari Village. Named “Katamura” from Makkari Village character Makkari Betsuta, and set up a government office in the current aza-motomachi. The town system was enforced in 1950, and the name was changed to Niseko Town in 1964. 2001 100 years since the opening of Niseko Town. This year marks the 120th anniversary of the milestone. Enforcement of “Niseko Town Town Development Basic Ordinance”. The town was separated from Makkari Village (Currently Rusutsu Village) in November 1901, and the Tocho Office was set up in the current Town district. The pioneer hoe was put down in the present Nishitomi area by the ancestors, and the town developed while confronting many difficulties under the harsh natural conditions. Overview of town history, prehistoric times : Paleolithic and Jomon period ruins are left in the town. The Paleolithic period was the final stage of the ice age, and the straits around Hokkaido were connected to the land, so it is speculated that people moved in search of food. In the Jomon period, the climate approached the current state, and the lifestyle changed from a dynamic life to a sedentary life. By this time, people are thought to have lived in the hills of the Shiribetsu River, and many ruins such as earthenware and arrowheads are left behind. Prehistoric times are revealed in the ruins. However, no records have been found from the Middle Ages (Kamakura, Muromachi period), when the Ainu society and culture were formed, to the latter half of the Edo period, and the actual situation remains unknown. Fascinate. More than 13,000 years ago, when tools were made mainly from stone and used on a daily basis to carry out daily life, pottery was used as a container and had a diverse cultural structure. It refers to the era from 1000 years ago to 2300 years ago. The town is located in the area called “Shiribeshi”, and the name was given by the pioneer ambassador in 1869, adopting the idea of Takeshiro Matsuura. Mr. Takeshiro investigated the basin of the Shiribetsu River twice at the end of the Tokugawa shogunate, and considered Mt. It is said that he called “Yotei”. In addition, it is said that the country name of this region was “Shiribeshi”. In the early Edo period, the river flow was strong upstream from the vicinity of Niseko Town, and it seems that there were no Ainu settlements because it was difficult to fish for salmon and trout. However, when I learned that this basin had abundant resources, I came to work during the fishing season. The Japanese clerk is Japan’s first Chokusenshu history book, completed in 720? It is said that when Abe no Hirafu-Ko, who was the national guard of the Hokuriku region, led the Navy to conquer Ezo, he set the rear Yotei as the administrative agency and appointed a county official according to the opinions of the two Ezo. Agricultural work during the pioneering period: In 1894, the land that had been the imperial forest was converted to a national forest. This makes it possible to cultivate. In 1895, a plot was set up, and a hoe for clearing was to be put in. Unlike other areas, the town is characterized by the fact that it has been cultivated by farms invested by capitalists in Honshu and group settlers, and among them, the nationally famous farm is “Arishima Farm”. A farm reclaimed by Takeshi Arishima (Mr. Takeo’s father: Although he was a samurai of the Shimazu clan, he was promoted as a bureaucrat of the Meiji government and retired as the director of the government bond bureau of the Ministry of Finance. Served as an officer. When the State-owned Undeveloped Land Disposal Law was enforced in Hokkaido in 1897, he started a reclamation project on 350 ha of land in Kaributo Village, Hokkaido.) in 1899 after receiving a wage cut on undeveloped land. The farm was taken over by Takero in 1908, but in 1922 he declared the farm open for free and gave the farmland to the peasants free of charge. The peasants organized the “Kaributo Symbiotic Farmers’ Association（Business: Agricultural land sharing, rice cultivation, dairy farming, joint purchase / use of materials / machinery, joint direct sales to the market.）” and managed all of the farm facilities as a shared property. This will continue until the 1949 Act on Special Measures for the Creation of Homegrown Farms comes into force. This act had a great impact on the society at that time.Before the liberation, it was the office of Arishima Farm and the residence of Mr. Takeo Arishima, after the liberation it was the office of Kaributo Kyosei Agricultural Co., Ltd., and after the dissolution, it was the first “Arishima Memorial Hall”, but it was destroyed by fire in 1957. The Arishima Thanksgiving Hall was built in 1963 with the cooperation of former union members and local residents. Around 1897, Kaributo Village (now Niseko Town) was considered to be an undeveloped land in Makkari Village, so all the duties including family register affairs had to go to Makkari Village. Around 1901, the movement of residents who wanted a branch village became active, and the first residents’ convention was held on September 17. On October 16th of the same year, a notification of the branch village was issued from Hokkaido, and the branch village will be approved in a short time. Regarding the revision of the town name, there was a movement in 1936, but as a result, it ended in misfire, and in 1966, the second katakana town “Niseko Town” was born by the second movement. Located in the southern part of Mt. Yotei, which is known as Ezo Fuji, it is a pure farming village that has developed with agriculture as its core industry. The main crops are potatoes, radishes, carrots, etc. Among them, edible lily roots It boasts the largest shipment volume in Japan. It is also well known as the birthplace of enka singer Takashi Hosokawa, and the Makkari River Park, which runs through the village, has a singing “Takashi Hosokawa Memorial Statue” and is said to be a popular tourist spot. The name of the village is derived from the Ainu language “Makkaripet”: a conversion from the river surrounding Mt. Yotei. Rusutsu Village was founded in 1872 when Higashi Honganji opened a new road to Usu district and moved to Sannohe. After passing through branch villages, the current Rusutsu Village was born in 1924. With an area of 119.84 km2, National Highway No. 230 runs from Sapporo to Toyako Onsen in the center of the village. Mt. Yotei rises to the north of the village, and is adjacent to Kimobetsu Town in the northeast, Makkari Village in the northwest, Toyako Town (Former: Toya Village) in the Iburi Subprefecture in the south, and Date City (Former: Otaki Village). At the foot of Mt. Yotei, the village of Rusutsu, a plateau of green and white snow, is an endless village of happiness, thanks to the hard work of its ancestors and the blessings of abundant nature, who endured the harsh wind and snow and broke the foundation of their hometown. Established a charter in hopes of its development. Rusutsu: Mr. Takeshiro Matsuura, a Japanese man who passed through the village more than 140 years ago. The footsteps are described in the “Backward Yotei Diary” (diary on February 2, 1952). “Go to Horonutsuf (Shino) Nutsukehetsu (Genya Kitakawa to Akota territory Hen) Yutoenka (Hara) Rusochi (Miscellaneous trees), It reaches Sorioi (at the foot of Yudake) . ” (“Takishiro Ezo Diary Collection No. 2” Japanese Classic Complete Works Publishing Association) Rusutsu in the text is said to be the origin of the name of Rusutsu today. One of the first people to settle in the village, Kazaemon Abe, moved to the village with Kuninari Date in April 1871 as a clan of the Sendai domain, and in 1872 he handled the station in Kimobetsu. He is said to be the first person to settle in village on record. Large farm management: In 1888, Bunzo Hashiguchi entered Rusutsu Village and moved to the United States at the age of 22 to study agriculture. He aimed to manage a large American farm and dreamed of a model farm by importing all the machinery from San Francisco. Abandoned the business due to labor shortage and inconvenient transportation, and in 1892 Yasuaki Kato took over the farm with Mr. Bunzo’s dream. Mr. Bunzo and Yasuaki Kato could not realize the concept of large farm management, but they left a big mark on Rusutsu agriculture and were the first to put a hoe in the village. In 1891, the predecessor of National Highway No. 230 started construction on the road from “Abuta” to Sapporo via Toya, Rusutsu, Nakayama Pass, and Jozankei, and was completed in 1895. This road played a major role in agricultural development at the foot of Mt. Yotei. The JA Yotei jurisdiction is located in the central and southern part of the Shiribeshi branch office jurisdiction in southwestern Hokkaido. In this position, there is the Conide-type independent peak “Mt. Yotei”, which is the symbol of this JA, and the countryside spreads around it, and you can see “Mt. Yotei”, one of the 100 famous mountains in Japan, from each area. The climate is generally warm and sunny from spring to summer, but in winter it is affected by the northwest monsoon, and there is a lot of snowfall, with heavy snowfall extending from mid-November to mid-April, especially in the foothills of Yotei. , It is one of the most heavy snowfall areas in Hokkaido. In local agriculture, a wide range of production such as rice farming, upland farming, vegetables, and livestock farming is carried out, and various management forms suitable for climate, soil, and climate conditions are formed. The Yotei Agricultural Cooperative is located in the southwestern part of the foot of Mt. Yotei in the Shiribeshi jurisdiction and consists of 9 towns and villages. It was established in March 1997 as a merged agricultural cooperative of 8JA. The head office is located in Kutchan Town, and there is “Mt. Yotei” in the center of the area, and the agricultural land spreads around it. Among agricultural productions, Jingle bells were designated as a vegetable production area as the “Mt. Yotei” area in 1974, and as a result of vigorous production promotion since then, they are now the main production area for edible horse bells in Hokkaido. It has been highly evaluated. Jingle bell, which accounts for one-third of the sales business, boasts a planted area of 3,500 ha and a collection volume of about 80,000 tons, and is a major pillar of JA. After the merger of JA, the “Yotei Agricultural Cooperative Edible Horse Bell Production Organization Liaison Council” (about 900 producers) was established in March 1997 to unify the production union activities inherited from the former agricultural cooperative. Toward the early establishment of the “Yotei brand”, we have been actively engaged in business with the aim of achieving high quality leveling, standardization and production promotion. Cultivation workshops, quality standards, acceptance handling standards, consumer area market research, etc. meet more than 20 times a year and consist of tireless efforts. Raw edible horse bells at the foot of Mt. Yotei are famous all over the country for their good taste, and even after the merger of JA, we focused on early shipment before the August bon, and long-term leveling by early shipment, the largest raw edible horse bell in Hokkaido. We have built a planned shipping system of 80,000 tons. It is sought after as a “Reliable Production Area” from mass retailers such as Keihanshin and Kanto. The producer proved that the crops were cultivated and harvested safely by observing the standards stated in the cultivation calendar such as daily control and fertilization by the efforts of all the members of the production history book, and in JA, before shipping. It is said that it is working to create a production area that is trusted by consumers by voluntarily conducting residual inspections of pesticides. In addition, a compost intensive treatment facility and a compost house have been developed to effectively utilize organic resources in the area and to build a function to circulate them. For that purpose, we will analyze the soil and compost components of the fields that require compost input, promote the systematization of compost input based on the soil diagnosis fertilizer application design, and promote sustainable circulation as a production base for edible horse bells. We are promoting type farming. The harvest of the early-maturing variety “Toya potato” has reached its final stage, and the harvest of the advanced cultivation “Baron potato”, which began in early August, has reached its peak, and 5,000 to 15,000 cases per day are shipped to prefectures. Kitakamui potato, the type is intermediate type, and the stem length is slightly shorter than that of ‘Baron potato’. The stem thickness is medium, the stem color is green with reddish-purple secondary colors distributed in a mottled pattern, the stem wings are slightly wavy, and the number of branches is small. The leaf color is lighter green than that of ‘Baron potato’, and the leaflets are medium-thin and large in size. The number of flowers is rather large and the flower color is white. The amount of pollen is slight, and the number of results is nothing. The length of the ventral ramus
is short, the depth of the root growth of the potato is shallow, and the grains of the top potato are somewhat regular. The shape of the potato is spherical, the skin color is white-yellow, and the epidermis is medium. The number of eyes is small, and the depth of the eyes is slightly shallower than that of ‘Baron potato’. The flesh appears to be white. In addition, the dormancy period is a little long, the initial growth is a little fast, and the withering period belongs to wase like ‘Baron potato’. The number of top potatoes per plant is about the same as that of ‘Baron potatoes’, and the average weight of each top potato is slightly larger than that of ‘Baron potatoes’. The starch value is low and it seems to be lower than ‘Baron potato’. Potato cyst nematode resistance gene H1 has the effect of inhibiting the maturation of larvae in the root. Ro1 seems to be the only potato cyst nematode occurring in Japan. 4 groups of DNA markers targeting PCN resistance genes H1, Gro1-4, and Gpa2 distinguish the presence or absence of 3 types of resistance genes. N146 and N195 are markers designed to sandwich H1 by Takeuchi et al. (2008), and it seems that if both markers are amplified, they almost certainly have H1.) and have “strong” resistance, potato common scab (As the name suggests, scab-like lesions appear on the epidermis of potatoes. The lesions are mainly brown, about 5 to 10 mm in size, and generally have almost no unevenness. In addition, there are large ones with a depressed center. These lesions and cushion-like raised lesions are often seen, and it seems that these lesions may coalesce and cover a wide area.) Resistance is weak, plague field resistance and Potato virus Y (in Japan There seem to be three strains of pathogenic viruses that have been confirmed: the common strain (PVY-O), the barley strain (PVY-N), and the tuber barley strain (PVY-NTN). PVY-O is mosaic type depending on the cultivar. In the mosaic type, the leaves become a little deciduous at first, then mosaic-like spots appear, the leaf margins are wavy, and the stems atrophy (Baron Potato, May Queen, Benimaru, etc.). The symptoms are often seen in the middle leaves, but the progress of the disease is relatively slow. However, when co-infected with PVX, it exhibits a remarkable curly leaf mosaic, a so-called “foliage mosaic disease”. It seems that the barb type produces clear streaks on the leaf veins and stems, and in severe cases, the plant dies (Norin No. 1 Potato, Toyoshiro, etc.) PVY-N symptoms are generally associated with PVY-O. It is considered to be mild in comparison, and detected in many Baron potato plants that appear to be symptom-free. It seems difficult to distinguish between PVY-O and PVY-N by symptoms.) Disease resistance is weak, tuber rot (At the ground, the disease mainly affects the leaves, and if it spreads violently, the entire field may wither. The plague also affects tubers, producing blackish dents on the surface, and the inside is brick-colored to brown. It also prefers moist climates and the conidia of the pathogen are washed away by rainfall and irrigation water. The damage spreads quickly to surrounding foliage. So be careful when it rains a lot.) resistance is rather weak. The central cavity is slightly smaller than that of ‘Baron potato’, the brown heart rot is slightly larger than that of ‘Baron potato’, and the secondary growth seems to be as slight as ‘Baron potato’. Phytophthora infestans (dark green wet lesions spread fan-like on the leaves and frost-like spots on the underside of the leaves). White mold (spores, etc.) occurs. When rainfall continues, it spreads all over the field. The disease progresses to tubers (potatoes), and it seems that the surface of the potato is dark and the inside is brown. Water-soaked soft rot lesions appear on the bottom leaves. This seems to be different from other bacterial diseases. The rot spreads quickly and reaches the main stem. After that, dark brown rot progresses from the base of the petiole up and down, and the vascular bundles. It seems that the pith turns brown, and eventually the pith becomes hollow and dies. In addition, it seems that there are many cases of infection and rot from wounds on the foliage caused by agricultural work. New tubers first have small reddish-brown spots on the dermis. Under high temperature and high humidity, the surrounding area becomes brown and indistinct spots, and the lower part melts into a creamy soft rot. If the soil is a little dry, the vascular bundles tend to turn brown, so it seems important to have a good balance between good drainage and water retention. In addition, when there is a lot of fertilizer, brown heart rot (small brown circular to irregular necrotic parts are scattered inside the vascular rings of tubers. Discolored parts do not seem to soften even when heated. This symptom is small. It is more likely to occur in larger potatoes, but it seems that there is almost no abnormality in appearance. In general, it occurs during growth, and there is no occurrence or progress during storage, and it seems that there is no problem even if it is used as a seed potato.) Be careful not to overfertilize as it becomes easier.
The plateau climate at the foot of Mt. Yotei, which is suitable for growing potatoes, and long-term storage produce sweet and delicious Kitakamui potatoes. The pulp is white and the flesh is soft, so the core does not easily remain after heating. From Mt. Yotei, there is a famous spring water spot near the trailhead of Makkari Village. Fukidashi Park is famous as “Blow Spring Water of Kyogoku”. This is located almost on the opposite side of Mt. Yotei. Both springs come from Mt. Yotei, and rain and melted snow that fall on the mountain are filtered (a mixture of liquids and gases mixed with solids) through many fine holes over the course of several decades. It is then passed through an open, filter medium, an operation that separates solid particles from liquids and gases), and is reborn as mineral-rich water.
The main cause of the phenomenon called central cavity disease is the sudden enlargement of the potato, which causes a cavity due to insufficient supply of carbohydrates and other substances necessary for growth. It occurs when rapid hypertrophy results in an inadequate supply of nutrients necessary for growth, such as starch, to the core. It seems that the main causes of rapid enlargement are excessive fertilizer, temperature at the time of enlargement, amount of rainfall, and too wide spacing between plants. Physiological disorders that are likely to occur in varieties such as Baron potatoes, but tend to be rare in varieties such as May Queen and Kitaakari. Since sorting is carried out using sensors at the production site, it is rare for produce to be shipped with a central cavity.
In Hokkaido’s Shiribeshi region, one of the famous potato production areas, many farmers use copper fungicide No. 22533 “Cocide® 3000”. Speedy drug solution preparation. Due to formulation improvement, it seems that the smoothness and fluidity have improved. A copper agent that is easy to measure and easy to handle even when preparing chemical solutions. Excellent preventive effect against a wide range of diseases. Copper ions have an excellent preventive effect against a wide range of diseases. It seems to be effective against not only diseases caused by fungi (mold) but also bacterial diseases. DF agent with less dirt. Since the fine particles of the active ingredient spread evenly and evenly on the surface of the crops, the sprayed liquid hardly leaves marks on the crops. For this reason, it is a copper agent that is easy to use even for crops during the harvest season. (If calcium carbonate is added, stains may remain.) Adoption of new technology is environmentally friendly. Adopts a new technology that exhibits sufficient sterilization effect as before with less copper content. Supports sustainable agriculture by minimizing copper accumulation in the soil. Ingredients: Cupric hydroxide 46.1% (30.0% as copper). Toxicity: Ordinary substances (a common name for substances that do not fall under the category of poisonous and deleterious substances). A copper wettable powder that complies with the organic JAS method. Suitable for special cultivation and organic cultivation. It seems that the main component is cupric hydroxide, which is very effective and stable among copper agents. A drug with relatively little phytotoxicity.
