姜景璿,宋昌吉 제주대학교 1983 논문집 Vol.15 No.2

(1) The mean atmospheric timperature of Jeju area is higher than that of Seoul by 3'c and in the coldest month by 8'c, so Jeju-do is regarded as important place to cultivate subtropical plants. Such a natural state has accelerated the crop production suitable to warm region front time immemorial. Jeju-do has become a main producing district of tingerines, sweet potatos, barleys and rapes since the beginning of 1960's and Jeju-do's latest main products are wintering vegetables such as cabbages, carrots, garlics and onions. Such a term favorable to an off-crop season is developing Truck Farming. (2) A milder winter causes us to save petroleum needed to cultivate plants under vinyl plastic hot houses, where some 200cc of petroleum is needed to cultivate a tomato, some 100cc to cultivate a cucumber, some 18cc to cultivate a melon, some 200cc to cultivate a tangerine, and some 50-60cc to cultivate an eggplant. (3) A case study on sales method of carrots, garlics and cabbagges shows that 64-60% of farmers sell out a crop estimate on vegetable garden before harvesting. (4) A case study on distribution margin shows that gross margin rate is 66.2% in carrots, 77.2% in cabbages and 53.6% in garlics, and the income rate of above-mentioned products in a farmhouse is 33.8%, 22.8% and 46.4% respectively, while transporting expenses…cabbages (23.2%), carrots (12.1%) and garlics (8.7%)…are given much more weight than any other expense. (5) Japan limitted the total output of vegetables with 16 million ton of vegetables in 600,000 ha of vegetable culture area to keep the change of demand safe in 1979, but the increase of vegetable culture area, both by changing rice fields and by the propensity to consume energy, is becoming primary factors in the alteration of vegetable product stucture. (6) The amount of annual vege table consumption per headof population has changed into 110kg, and the vegetables consumed over 5kg are cabbages, onions and radishes and sweet potatos. Cucumbers are staying between 4kg and 5kg. The present propensity to consume vegetables represents multiformity, annual plants and high-grade food, with western vegetables as the central one. (7) The amout of Jepanese in agricultural, forestry and marine fields came up to $ 29,055, 000,000 in 1980. The income amount in agricultural products reaches $ 14,911,000,000 wich is equal to 51.3% of total. The income amount in fruits and vege tables reaches $ 1,420,000,000 which is equal to 95%, America holds the foremost place as importer Country of agricultural and marine producss and Taiwan the sixth place, but Korea fakes 11th place, earning $ 738,000,000 annually. The income amount from Korea in agricutural comes up to $ 152,000,000. (8) The income amount of vegetables in Japan reached $ 107,800,000,000, and the change of vegetable income (1965-1978) tells that income amount has increased the quantity by 17 times. Main articles of vegetables are frozen vegetables and salted ones. (9) No importer countries surpass America and Taiwan. The export share of fish and vegetables in Taiwan and Korea shows that Taiwan exports 24.3% of total Japanese import (2nd position) , while Korea does 2.8% (5th position). For frozen vegetables, America holds the first position, exporting 48.6% and Taiwan the 2nd position, exporting 31.4% , while for dried vegetables, Taiwan holds the first position, exporting 42.9% and Korea 5th position, exporting 2,8%. Also, for salted vegetables Taiwan exports 63.4% (1st) and Korea 3.1% (3rd), while for prepared vegetables, Taiwan exports 78% (nst) , and Korea 2% (5th). (10) The agricultural effort amount of Korea came up to $182,000,000 which corresponded to 0.9% of total export, $20,993,000,000, while the export amount of Jeju-do reached $ 593,000, corresponding to 0.3%. The raw silks of Korean agricultural products in 1975 were main export articles, corresponding to 58% of total agricultural products, but they are remarkably decreasing into 14.3%. The vegetable export share was 2.2% in 1975, but 11.8 percent increase in 1981 is a characteristic found only in the vegetable export. Thus, the fact that vegetables are given much weight in the export structure of agricultural products shows an important change and the probablility to develope in the future. Therefore, in the aspect of vegetable export, diversified studies are needed to prepare good vegetable-producing center and to foster special artfole like dried, salted, frozen, and manufactured vegetables.

ABSTRACT Two sudangrass hybrids were treated with the split application (1, 2, 3, 4, and 5 times) of 25 kg/lOa of N to determine the effects of split N application on the growth, yield and feed composition of sudangrass hybrids in Cheju. Pioneer 988 headed five days earlier than Pioneer 931 did. The number of days from planting to heading averaged across the two hybrids was delayed from 73 to 79 days as the frequency of the split N applications was increased from one to five times. At heading, Pioneer 988 was about 8cm taller than Pioneer 931 was. Plant height was increased with increasing the frequency of split N application. As the frequency of split N application was increased, stem weight, leaf weight, root length, and root weight were significantly increased. Fresh forage yield averaged the two hybrids was increased from 5,505 to 7,391 kg/lOa as the frequency of the split N application was increased from one to five times. As the frequency of the split application was increased, crude fat and crude protein contents also were increased but crude fiber content was decreased.
