경제발전이란 사회함수의 맥동을 통한 생산력의 증대이며 이 궁극적 목적은 사회의 경제적 후생의 증진에 따른 국민생활의 향상에 있음은 말할 것도 없다. 국민의 생활은 경제발전과 소득의 증가에 따라서 그 양상이 달라지며 이는 지역별 또는 산업별에 따라 경제생활의 수준맥동이나 그 구조도 달라지게 마련이다. 우리 나라도 현재 100대 60 정도로 알려지고 있는 도시와 농촌의 소득과 소비생활면의 격차를 줄이고 농업생활을 향상시키는 것이 국가정책의 주요한 목표의 하나가 되어있다. 이 목표가 이루어지지 않는 한 사회의 경제적 후생의 증진에 따른 국민생활의 향상은 불가능한 것이다. W.W.Rostow는 후진국의 기형적인 경제발전을 비판하고 다음과 같이 지적하였다. 즉 「급속도의 공업화에 따른 지나친 의욕때문에 신생 독립국 가운데는 농촌발전에 중점을 둔다는 것을 마치 신식민지화가 되어 선진국가에 예속된다고 생각하는 국가가 많은 것 같다. 이러한 결과로 이들 국가의 도시는 공업화되고 현대적인 면모를 보이고 있으나 농촌은 침체내지 답보상태에 있게 된다.」 이것은 농촌이 경제발전의 기본조반이 된다는 것과 농촌과 공업이 같이 발전되어야 한다는 것을 뜻한다.

`FRP FEED BIN 선택시 가장 큰 문제점은 품질의 균일성, 강도, 후도, 재료의 안정성 등을 신뢰하기 어렵다는 것이며, 철판보다 3배 이상 고가라는 점이다. 또한 발암물질을 생성하는 FRP 용기도 문제가 된다.

These studies were carried out to investigate the characteristics of flower and correlation coefficients between some quantitative characters on wild Cymbidium virescens Lindl in Chung-nam, Korea. No. of flower stem per plant was 3.60 on average and frequency of two flower per plant was shown to be 7.14%. Length of flower stem was 17.18㎝ on average. Width and length of flower were shown to be 57.10, 32.55㎜ on average, respectively, and ratio of length about width were calculated to be 57%. The size of dorsal, lateral, petal, lip, and column was variousness. Among flower type, horizontal, drooped, and other were shown to be 7.43, 20,00, and 7.14%, respectively. Leaf width showed a significant positive correlation with width of dorsal, lateral, petal and column, and both width and length of flower were also significantly positive correlated with flower length(length of dorsal, lateral and petal).

According to the effect of temperature on the visible flower bud formation and flowering, they were promoted as ADT decreased: none of four cultivars differentiated flower bud at higher temperature such as 25C and 30C ADT. At 20C, days to flower bud formation in Snowflake 'Red Star', Malones 'Fantasy' and Yukidaruma 'King' was quitely delayed wheres days to flower bud formation at 15C was a little bit more advanced than those at 20C and more advanced in Yukidaruma 'King' and Snowflake 'Red Star' than in Golden Blossom 'Kogane' and Malones 'Fantasy'. On the basis of these results, it was found that flower bud formation of Dendrobium was accomplished by low temperature(below 15C) and the flowering and ripening of stem after occurrence of flag leaf were accelerated by high temperature. In addition, flower bud formation and flowering were markedly stimulated by BA 200ppm application, showing the additive effect with low temperature.

The study was carried out to determine the optimal electric conductivity(EC) of nutrient solution on semi-forcing culture of tomato variety groups in hydroponics. Eight varieties of cherry tomato('Mini Carol', 'PePe', KoKo', 'Dadaki', 'Suncherry Extra', 'Popitsuto', 'Fire Fly', and 'Chelsea Mini'), two varieties of pink color tomato('House Momotaro' and 'Kanpuku'), and two varieties of red color tomato('Red Giant' and 'Apollo') sowed January 8 and harvesting them from April 28 to July 21. The experiment was carried out plastic house condition. Culture medium of hydroponics mixed with perlite 7 and charcoal 3(v/v). The composition of macro nutrient in Yamazaki's tomato solution was as follows: N 7 meq, P 2 meq, Ca 3 meq and Mg 2 meq/liter. The treatment EC was 1.4, 1.7, 2.0, and 2.3mS/cm. EC of planting stage was 0.3mS/cm less than treatment EC and gradually increased to treatment EC(increase 0.1mS/cm every 15 days). EC of last harvesting time 3 weeks ago was 0.1mS/cm less than treatment EC. 1. Plant height of 'Mini carol', 'PePe', 'KoKo' and 'House Momotaro' at 30 days after transplanting was increased by 1.4mS/cm more than 1.7, 2.0 and 2.3mS/cm in nutrient solution, and 'Dadaki', 'Fire Fly', 'Chelsea Mini' and 'Red Giant' was increased by 1.7mS/cm more than 1.4, 2.0 and 2.3mS/cm in nutrient solution, and 'Popitsuto' was increased by 2.0mS/cm more than 1.4, 1.7 and 2.3mS/cm more 1.4, 1.7 and 2.0mS/cm in nutrient solution Stem diameter of tomatoes was thickened on increasing the concentration of nutrient solution at after fifth cluster. 2. Total fresh yield of cherry variety group and pind color tomatoes was increased by 4∼26% and 3∼25% on 1.4mS/cm more than 2.3mS/cm in EC of nutrient solution, respectively. 'Red Giant' of red color group was increased by 9% on 2.0mS/cm more than 2.3mS/cm in EC of nutrient solution, and 'Apollo' of red color group was incresed by 11% on 2.3mS/cm more than 1.4mS/cm in EC of nutrient solution. Marketing yield of cherry variety group and 'House Momotaro' of pink color tomato was increased by 14∼44% and 47% on 1.4mS/cm more than 2.3mS/cm in EC of nutrient solution, respectively. 'Kanpuku' of pink color group was increased by 11% on 1.7mS/cm more than 2.3mS/cm in EC of nutrient solution, and 'Red Giant' of red color group was increased by 21% on 2.0mS/cm more than 2.3mS/cm in EC nutrient solution, and 'Apollo' of red color group was increased by 3% on 2.3mS/cm more than 1.4mS/cm in nutrient solution. 3. The appearance ratio of small fruit was increased by 2.3mS/cm more than 1.4, 1.7 and 2.0mS/cm nutrient solution of cherry tomato group, and by 2.0mS/cm more than 1.4, 1.7 and 2.3mS/cm in nutrient solution of 'House Momotaro'·'Kampuku'·'Apollo', and by 2.3mS/cm more than 1.4, 1.7 and 2.0mS/cm in nutrient solution 'Red Giant'. 4. Average fruit weight was increased by 1.7mS/cm more than 1.4, 2.0 and 2.3mS/cm in nutrient solution of cherry tomato group, 'Kanpuku' and 'Apollo', and by 1.4mS/cm more than 1.7, 2.0 and 2.3mS/cm in nutrient solution of 'House Momotaro' and by 2.0mS/cm more than 1.4, 1.7 and 2.3mS/cm in nutrient solution of 'Red Giant'. Soluble solids was significant on tomato varieties. By increasing the concentration of nutrient solution, soluble solids increased. 5. Firmness of fruit was increased 'Chelsea Mini'(Fruit equator : 0.62∼0.64kg/㎠) among the cherry tomatoes and 'Apollo'(Fruit equator : 0.65∼0.69kg/㎠) among the non-green back tomatoes.

These studied were carried out to understand factors affect to somatic embryogenesis through culture of immature embryo segment of radish. Results are summarized as follows: 1.Though compact calli were formed in MS media, there were not in 1/2MS media or 1/4 MS media.Direct embryogenesis was not detected in MS media but foundat in 1/2MS media. 2.Supplement of 2, 4-D 1 mg/L had an effect on induction of compact callus. 3.Some compact calli were induced from upper part segment of hypocotyl and lower part segment of cotyledon but not from lower part segment of hypocotyl. Somatic embryos were induced directly from lower part segment of cotyledon. 4.Pretreament of 35℃ for I day increased compact callus induction rate. 5.The frequencies of compact calli were formed from Taebaek variety were bigber than Kungjung. Compact callus from both varieties developed into embryos by subculture in growth regulators free media. 6.The frequency of comact callus was formed was 10% in dark condition but not in light condition. 7.Through subculture in growth regulators free media, 40% of compact callus developed into embryos but loose callus didn't.

This study was aimed to determine the effect of basal application of Effective Microorganisms (EM) on the grow and yieldof cucumber. For treatments, the EM was applied to soil with fertilizer composed with N-P2O5-K2O-manure (24.0-16.4-23.8-2,000kg) in the 1.0 strength (defined as EM+1S), 2/3 strength (defined as EM+2/3S), 1/2 strength (defined as EM+1/2S), without fertilizer (defined as EM), or only fertilizer in the 1.0 strength (defined as 1S). In result, there was no significant differences of organic substance content and pH with the EM treatment. While the EC (Electric conductivity) concentration was decreased, plant-available P (phosphorus) was markedly increased. Chlorophyll content was highest in thetreatment of EM+standard application rate for both semi-forcing and retarding culture. In contrast, no significant difference was found in plant height and internode length under the fertilizer treatment. Weekly harvested number of cucumber was highest at the treatment of EM+standard application for the semi-forcing culture, while it was 3.6 at the EM+1/2 application for the retarding culture. Weekly yield was greatest at the EM+standard application treatment and decreased with the decrease of fertilizer application rate. In addition, weekly yield was significantly reduced in the treatment of EM . There was no significant difference in yields by production time with the fertilizer applications?. Yield was increased with temperature for the semi-forcing culture, while consistent pattern was maintained for the retarding culture.
