  • The purpose of this study is to analyze the performance of the fig farms based on the survey data. The survey of 12 farms was conducted during the period from August to September. The result shows that the productivities of land and the productivities of labor of the developed nutriculture farms are higher than those from traditional conventional culture farms and nutriculture farms. Incomes of the developed nutriculture farms are also higher.

  • During late July 2020, a species of weevil in the genus Aclees (Curculionidae, Molytinae) was found on several fig farms in the Haenam-gun district of Jeonnam Province, Korea. The weevil was subsequently identified as Aclees taiwanensis Kôno, 1933 (Coleoptera: Curculionidae), an exotic species, probably of subtropical and tropical Asian origin, that has also been introduced to Italy and France, where it is associated with severe damage to fig trees. This is the first report of an Aclees weevil in Korea.

  • This study was performed to estimate the daily water consumption for watering livestock and home use, and to organize the water systems in the rural districts of Korea. For these purposes, 560 farms and other 40 urban families were randomly chosen and investigated about their water systems and daily water consumption seasonally from July 20 to August 31, 1973, and other 82 livestock raisers' useful data for watering livestock helped the study to assess the consumption of livestock water and compare it to that of general farms which bred some domestic animals as their sidelines. The results of data showed that the daily consumption of water was varied with the difference of districts and seasons in which the investigations were conducted. The results were summarized as follows. 1. The mean consumption of water for home use was varied with the range of 30.2-48.7 lit./day in summer and 22.4-45.2 lit./day per a person, respectively, in the rural districts, which showed that the water consumption in summer was more than in autumn. 2. The mean consumption of livestock water in the general farms approached to about 15.8-37.1 lit./day per cattle, 3.87-16.45 lit./day per a pig, and 0.19-1.03 lit./day per chicken, but it was slightly reduced in autumn; 10.89-37.09 lit./day per cattle, 3.87-12.63 lit./day per a pig, and 0.06-0.94 lit./day per chicken. The ratio of livestock water consumption to home use amounted to the range of 10-25%. 3. The mean consumption of livestock water used at the livestock raisers amounted to 134 lit./day per dairy cow, 67.4 lit./day per cattle, 43.29 lit./day per a horse, 13.24 lit./day per a pig, 0.438 lit./day per a layer, and 0.177 lit./day per a broiler, which showed that the daily water consumption for larger livestock was about two times as much as the farms, but it was approximately of the same for small ones. 4. The factors affecting the amount of water consumption for home use were statistically analyzed to find the kind of water sources and the class of water systems by the factorial arrangement method to the fundamental experimental unit, Suwon area of 100 of families, in which the former was very significant while the latter was significant. However, the standard of living and their interactions were not significant. 5. Almost 83.24% of the sampled farms used some kinds of wells as their water sources, of which 32.06% was of hard water, and of which 11.l% or 2.6% contained much of iron or organice materials, respectively, examining them by a simple technique of sensibility, 6. The resulting chart of the farm water systems was summarized as Fig. IV-6. Observating the safe distance from contamination sources, the ratio of 42.4% of sampled farms whose water sources were wells, confronted highly to the danger of contamination to their water sources. And other dangerous sources of contamination such as toilets, stalls, and compost heaps were situated nearly to the water sources, and most of them were able to make their spoiled water infiltrated into the ground. Thereafter, it was recommended to develop some protecting methods and to install some suitable faculties to clean water.

  • To investigate provincial seed Potato Production farms, a Preliminary survey on the local population of the aphids was made in Sulchon alphine area, Mooju-Goon, Chollapuk-Bo where the climatic conditions were almost same as those of Taegwanryong Kangwon-Do, where Alpine Experimental station is located. This area stands from 650 to 900 metres above the sea level and divided three location of A. B, C, by altitude. A stands at 900 metres above the sea level. B at 750 metres and C at 650 metres. A and B divided three points: Al, A2, A3, and Bl, B2, B3- and divided four points-Cl, C2, C3, C4- at the distance of 300 metres apart each other. The traps were operated from July 21 to October 31, 1969. Otherwise, the traps established at Suwon (inland) and Taegwanryong where Alpine Experimental Station. A total of some 70 species including five virus vector species were identified. The Numbers of species at 10 locations, Suwon and Taegwanryong are as follows; Al-34, A2-38, A3-29, B1-25, B2-26, B3-29, C1-27, C2-14, C3-32, C4-37, species (Table 1), Suwon-49 species (including 5 virus vectors species), Taegwanryong-22 species (including 4 virus vector species). The aphids are shown in Table 1 and the Vectors are as follows: 1. Aphis gossypii Glover 2. Aulacorthum solani (Kaltenbach) 3. Lipaphis erysimi (Kaltenbach) 4. Myzus persicae(Sulzer) 5. Phorodon humuli (Schrank) Numbers of vectors versus total aphid at each locations, including inland (Suwon) and alpine area (Taegwanryong) where Alpine Experimental Station are as Fig. 1. Of a total 8,902 aphids, 6,400 $(80\%)$ were Tetraneura sp. The number of aphids devoid of the number of Tetraneura sp. are as follows; (Numbers means mean of each locations) A; 215. B; 115, C; 176 and Suwon; 2,952, Taegwanryong; 247. Densities of aphids at the locations is lower :han those at Suwon and Taegwanryong. And density of vectors at the locations, at ranged from 11 to 37, is love. than those at inland (Suwon; 197) and alpine area (Taegwanryong; 90). Thus, this area is suitable for seed potato production as Multiplication field.
