금년의 우리나라 옥수수 재배면적을 종자공급량으로 추정해보면 종실용과 사일레지용을 합하여 약 32,900 ha 이며 단옥수수가 약 4,000 ha 재배될 전망이다. 이렇게 옥수수가 새로운 환금작물로 대두됨에 따라 재배방법의 보급은 물론 특히 제초제에 어려움을 느끼고 있다. 옥수수의 제초작업은 농민들의 제초제에 대한 인식과 지식의 부족으로 대부분 인력으로 수행되고 있는데 제초작업의 어려움과 최근에 더욱 심각해진 농업노동력의 부족, 노동임금의 상승 등을 고려하면 옥수수재배에서 제초제의 사용은 불가피하다.

To produce and supply the healthy potato, basic seed potatoes were produced by stem cutting, microtuberization and hydroponic culture. The total number of tubers and the total tuber weight per $\textrm{m}^2$ of potato were more in hydroponic culture as each products were 1, 152 and 4, 492g than in the stem cutting (75 and 4, 136g) or microtuberization (1, 080 and 1, 080g) using petridishes. The total yield per 10a in the field was propagated highly stem cutting > propagated microtubers > hydroponics > microtubers. The number of tubers per 10a produced by hydroponics (33, 064) was higher than any other methods. This indicated the hydroponic culture can be used in the multiplication of basic seed potatoes.

콩나물을 재배하는 과정에 있어 원료콩의 선택은 매우 중요하다. 재배장의 환경이나 내부구조, 공급지역의 소비취향, 자신의 재배방법 등을 품종결정의 이유로 삼고 있으나 결정적인 것은 재배에 이용되는 지하수질에 의하여 거의 결정된다고 봐야할 것이다. 각 지방별로 천차만별한 기후조건, 또는 지하수질, 그리고 같은 지역이라 해도 재배상 환경등이 모두 다를 수 뿐이 없는데 여기에는 어떤 콩을 사용하고 있는지 알아보자.

The field trial was performed to evaluate the rice growth and yield in different direct seeding methods after Italian Ryegrass Harvest The required time for seed emergence was for 7 ~ 8days in the tested direct seeding methods and there was high in seedling establishment in order of wet hill-seeding with iron-coated seeds > water seeding with iron-coated seeds > wet hill-seeding with soil coverage with pregerminated seeds. The rice plant height was shorter in the tested direct seeding methods than that of machine transplanting until 45day after seeding but there was not significant difference in terms of statistical analysis at 63day after seeding. The growth of tiller number in the rice plant was high in water seeding with iron-coated seeds and wet hill-seeding with soil coverage and low in wet hill-seeding with iron-coated seeds compared to machine transplanting. The yield component in the tested direct seeding methods was not significant difference in terms of statistical analysis. The milled rice yield in the tested direct seeding methods was higher 2 ~ 8% being with 4.94 ~ 5.24t/ha than that of machine transplanting but there was not significant difference in terms of statistical analysis. The percentage of head rice was low in the tested direct seeding methods compared to machine transplanting. The weedy rice was not occurred in the tested rice cultivation methods. In conclusion the direct seeding method would be recommended to be a suitable to in following by Italian ryegrass harvesting in southern area of Korea in terms of reduction in production cost and high income basis for rice growing farmers.

우리나라의 느타리버섯 재배는 70년대 후반 농촌진흥청에서 볏짚다발재배기술을 개발 보급하면서 느타리버섯 재배기술이 보편화하였으나 80년대 후반부터 점차 노동력을 절감 할 수 있는 폐면을 이용한 재배 방법으로 변화되었다. 그런데 이 폐면재배 방법은 해외에서 폐면을 대량 수입하여 사용하고 있으므로 외화낭비와 더불어 식물병균, 곤충, 잡초 등이 반입될 수도 있으며 재배기술면에서도 볏짚다발재배에 비하여 까다롭고 버섯병 발생이 쉬워 버섯재배에 실패하는 농가가 많은 실정이다. (중략)

This study was conducted to establish the environment-friendly cropping system of soybean in paddy field with different soil textures. When the soybean was cultivated in paddy fields, growth responses of testing cultivars varied depending on soil texture and cultivation method. Growth responses of soybean in sandy loam tended to be better than those in clay, however the effect of high ridged cultivation was distinguished in clay loam. Especially, formation of rhizome nodule was significantly different depending on soils ; more numerous rhizome nodules were formed in sandy loam compared to that in clay. Plant heights of Taekwangkong and Eunhakong were highest in clay and sandy loam, respectively, while the number of pods and branches of Eunhakong were most in both soils. In clay paddy field, growth responses of Eunhakong were best among the testing cultivars, however high ridged cultivation was more appropriate to the cultivar compared to level row cultivation regardless of soils. Taekwangkong showed the highest leaf area indexes during whole growth stages. Leaf development of Daewonkong was suppressed in clay at early growth stage, while it significantly increased as growth stages progressed. Most retard leaf development was observed in early maturity cultivar, Hwaseongputkong, since it seemed to be seriously damaged by excess-moisture injury in both soils. Comparing the dry weight of top plants and roots, plant growth was more affected by soil texture than cultivation methods at early vegetative growth stage, via verses at R2 or R5 stages. In yield characters and yields at R8 maturity stage, pods number of Eunhakong was significantly higher than those of Daewonkong and Taekwangkong estimating to 107 and 124 in clay and sandy loam, respectively. The ratio of ripened seeds was highest in sandy loam in combination with high ridged cultivation, while the lowest in clay with level row. The yields of Deawonkong and Eunhakong were higher compared to other testing cultivars ranged from $l82{\sim}286kg/ha$ depending on soils and cultivation methods. In results, growth responses and yields of testing cultivars tended to be higher in sandy loam in combination with high ridge compared to clay with level row.

This study was undertaken to survey the pesticides used under the greenhouse cultivation of 9 vegetable crops including cucumber, tomato, strawberry, eggplant, hot pepper, paprika, lettuce, perilla leaves and green onion in the Southern area during the period of 2003-2004. The total number of farmers investigated was 202 which consisted of 124 conventional growers and 78 environment-friendly growers. The farmers were requested to record with respect to the crop's name, cultivation acreage, growing practices (conventional/environment-friendly), use purpose, pesticide kinds, usage quantity and application time of pesticides. The average usage quantity of pesticides for the 9 crops was 3.30 kg ai/ha in conventional growing and 0.47 kg ai/ha in environment-friendly growing. The average application time of pesticides was 11 times in conventional and 2 times in environment-friendly growing, with more than 90% cases as a foliar application. The number of active ingredients of pesticides was 34 in conventional and 10 in environment-friendly growing on the average per crop. The purpose of pesticide application was as a fungicide in 56% cases and as an insecticide in 43% cases.

건고추 재배에 있어서 여러 차례에 수확하는 관행의 방법을 단 한 차례에 수확(일시수확)하려면, 적과의 착과수를 증가시키고 착과시기를 집중할 수 있는 방법이 모색되어야 할 것이다. 그러기 위해서 고추가 유한화서이면서 일시에 적과로 성숙되는 특성을 가진 품종이 우선 개발되어야 하지만, 재배방법이나 약제처리에 의한 착과 및 착색을 조절하는 방법도 시도되어야 한다. (중략)

Trees, cultivated in containers, are appropriate in soil deformation such as road sites with cutting and filling. This study tested the effectiveness of trees produced in containers for early rootage in street tree transplantation. For the study, Korean Mountain Ashes(Sorbus alnifolia) were used for experimental groups. The groups were categorized into three categories: trees cultivated in containers with mulching treatment(group A), trees cultivated outdoors with mulching treatment (group B), and trees cultivated in containers with weeding treatment(group C). Each group consisted of ten trees of the same size and transplanted to the experimental site. In order to compare each group's rootage, the study was carried out with the chlorophyll fluorescence method by the analysis of photochemical reaction. As a result of the study, group B had the lowest the maximum fluorescence amount(P). The amount of fluorescence increased by OJ transition of the process, and appeared to reduce the photosystem II electron transport efficiency. In photosystem II, electron transfer energy flux through photosystem I(RE1o/RC, RE1o/CS) was also reduced by more than 20% in group B. These results may imply that transplantation of container-cultivated trees with mulching treatment provides the most rapid rootage among the groups. The weeding treatment is also more effective than mulching treatment for rapid rootage of street trees.

To evaluate growth adaptation of the soybean in paddy field, five soybean cultivars were grown in Yeoncheon with two cultivating methods, level row and high ridge. Growth characters of the top plants, such as stem lengths, numbers of branches, diameters of stem, were higher under high ridge than under level row. However, the differences among the cultivars were bigger than those between the cultivation methods in each cultivar. Comparing the growth of top plants, dry matters in level row were higher than those in high ridge in V5 stage, however, via verses as growth progressed with significant differences among the cultivars. Roots were more developed under high ridge than those under level row during whole growth stages, such as V5, R2, and R5 stages. T/R ratio in level row was significantly higher than that in high ridge with significant differences among the cultivars.
