This study was carried out to investigate the difference of the content of soil chemical components and growth characteristics in five years old ginseng affected by application of manure in paddy-converted field. As all livestock manure regardless of kinds increased along with the whole soil chemical component, including the pH and EC in 2008. Change in the EC of control plot was slightly increased but not exceeded 1 ds/m over the years. However, the changes in the EC of livestock manure regardless of kinds and amounts were highly increased and irregularly exceeded 1.5 ds/m in 2012. The 5 years old ginseng root fresh weight, treatment of fertilizing pig manure compost 4 ton per 10 areas (PMC 4t on/10a) and fowl manure compost 4 ton per 10 areas (FMC 4 ton/10a), were superior to the others. But there were no difference between PMC 4 ton/10a, FMC 4 ton/10a and control. The standing crop rate 39.6%, treatment of fertilizing cattle manure compost 4 ton per 10 areas (CMC 4 ton/10a), was best in all livestock manure. However that was relatively lower than control. Physiological disorder occurrence rates of livestock manure related with leaf and root of ginseng were also higher than that of control. If excessively using non-decomposed livestock manure, It would be caused physiological disorder in many ways. It is a big problem to be producing the quality ginseng. More research is needed to find out the economic and effective fertilizer.

Morphometric changes in the Ussurian bullhead, Leiocassis ussuriensis, and the Korean bullhead, Pseudobagrus fulvidraco, were observed during the early period of growth. Yolk length, yolk height, and yolk volume in the two species decreased within 9 days post-hatching (DPH) (p<0.05). The body lengths and body heights of both species increased gradually to 150 and 130 DPH, respectively (p<0.05). The horizontal distance between the anteriormost extension of the head and the anterior insertion of the pectoral fin, the anteriormost extension of the head × the verticality position of the anterior insertion of the primary dorsal fin rays, and the anterior insertion of the primary dorsal fin × the anterior insertion of the pectoral fin were greater in the Korean bullhead than in the Ussurian bullhead (p<0.05). However, the relative sizes of the head region, pectoral fin, ventral fin, and anal fin were greater in the Ussurian bullhead than in the Korean bullhead (p<0.05), and relative body depth and the size of the outer-mandible barbel were greater in the Korean bullhead than in the Ussurian bullhead (p<0.05). The growth curves of the morphometric characteristics of both species were divided into three types.

This study was carried out to have the basic and applied information to develop the cultivation methods and models and to increase the productivity of high-quality ginseng. Plant height was dramatically increased from one year old to four years old, and then it was grown up very slowly. Stem length was shown similar tendency as the plant height did. Its range were from 9.4 cm in one year old to about 42.4 cm in four year-old ginseng. The leaf area was clearly increased until four years old, 10.1cm2 in one year old to 204.9cm2 in four years old, while it was slightly increased after four years old. Root length was continuously increased from one year old until four years old, and then it was grown up very slowly. Tap root length which was measured was appeared about 8 cm from three years old to six years old, showing not much different among the year-olds. The root diameter was continuously increased from one year old to six year-old ginseng, about 2.9 mm and about 19 mm, respectively. The moisture content was higher on the shoot than that on the root. It was slightly decreased as they were getting old. In shoot part, the rate of leaves and stems based on dry weight was about 1 : 1. In the root, the dry weight of tap root was heavier than that of lateral root. The dry weight of shoot was decreased after four years old, while it of the root was continuously increased until six years old, resulting the production of ginseng root. Based on the results of this study, growth characteristics of shoot and root of ginseng were dramatically increased from one year old to four years old and then their growths were appeared different between shoot and root, showing not much growing in shoot and keep growing in root.

The management and control of mineral nutrients is one of most important techniques to increase the productivity and the quality of Korean ginseng. The mineral nutrients are measured with different plant tissues and different growth stages of 2-year-old ginseng grown under hydroponic culture with two different temperatures. The content of N, P, Ca, and Mg were higher at low temperature in both leaves and roots than those at high temperature. However, the content of K was high in leaves at low temperature compared to that of high temperature, while it was not significantly different in roots. The uptake amounts of N and K was higher throughout the experimental period at low temperature in both leaves and roots than those at high temperature. However, the uptake amount of P was not clearly different between two different temperatures and among six different growth stages. The uptake amount of N, P, K was generally decreased in leaves from June to August, while it was increased in roots. The relationship between dry weight and mineral nutrients in leaves was appeared positive with N, K, Ca, and Mg, but negative P. In roots, N, K, Ca, and Mg were negative, showing that was positive with only P. Comparing the correlation coefficients among mineral nutrients in leaves, N and K were significantly positive correlation each other. P was significantly positive correlation with Na and Zn. In case of roots, N was highly significant positive correlation with K, Mg, and Mn, but P was negatively correlated with Ca, Cu, Na, Fe, and Zn.

Drought is one of the major abiotic stresses in agriculture affecting major crops worldwide. Any step taken towards improvement of either crops or its growing conditions which enables the crop to produce comparable yield with less water will help substantially to combat this problem. Water regulating gel-like growth substrate called PRS claims to improve the water use of the plants and helps them to grow better and bigger with less water. To test this claim, we used two crops Pepper and Ficus to grow in pot system with and without PRS. To monitor their growth variation with detailed and precision phenotyping we used the high-throughput, non-destructive digital phenotyping platform- PhenoFab®. The continuous growth information enabled capturing of minor growth variations seen in the plants treated with and without PRS. Results reveal that no significant growth differences were found between PRS treated and non-treated plants, however the PRS treated plants needed 35% less water compared to the non-treated plants. Hence, PRS allows use of less water to grow plants.

This study was conducted to examine major growth responses, the production and partitioning of dry matter on different growth stages, and yields and to select the optimal shading material in both quality and productivity of ginseng. Two cultivars of ginseng, Cheonpoong and Geumpoong, were cultivated in the paddy soil with three different shading materials; three-layered blue and one-layered black polyethylene (TBP), blue polyethylene sheet (BPS), and aluminium-coated polyethylene sheet (APS). Plant heights were linearly increased until June 24 and then maintained with showing higher height in Cheonpoong than that in Geumpoong cultivar. Root lengths were gradually increased until October 16. They were longer in Cheonpoong than that in Geumpoong cultivar, showing slightly longer with APS compared to TBP and BPS. The ability of producing dry matter of leaves was much higher from April to June compared to those of other growth periods, whereas its ability of root was concentrated from the end of June to the end of August. Among the shading materials, the ability of producing dry matter of shoot was higher with TBP than those with BPS and APS, while its ability of root was not appeared certain tendency unlike the shoot. The yield of ginseng roots was the highest with TBP among three shading materials and it was higher in Cheonpoong than that of Geumpoong cultivar. The shading materials which affect the light intensity and the temperature would be considered as an important factor to get better quality and productivity of Korean ginseng.

For developing the site-specific fertilizer management strategies of crop, it is essential to know the spatial variability of soil factors and to assess their influence on the variability of crop growth and yield. In 2002 and 2003 cropping seasons within-field spatial variability of rice growth and yield was examined in relation to spatial variation of soil properties in the· two paddy fields having each area of ca. 6,600m2 in Suwon, Korea. The fields were managed without fertilizer or with uniform application of N, P, and K fertilizer under direct-seeded and transplanted rice. Stable soil properties such as content of clay (Clay), total nitrogen (TN), organic mater (OM), silica (Si), cation exchange capacity (CEC), and rice growth and yield were measured in each grid of 10~times10m . The two fields showed quite similar spatial variation in soil properties, showing the smallest coefficient of variation (CV) in Clay (7.6~%) and the largest in Si (21.4~%) . The CV of plant growth parameters measured at panicle initiation (PIS) and heading stage (HD) ranged from 6 to 38~% , and that of rice yield ranged from 11 to 21~% . CEC, OM, TN, and available Si showed significant correlations with rice growth and yield. Multiple linear regression model with stepwise procedure selected independent variables of N fertilizer level, climate condition and soil properties, explaining as much as 76~% of yield variability, of which 21.6~% is ascribed to soil properties. Among the soil properties, the most important soil factors causing yield spatial variability was OM, followed by Si, TN, and CEC. Boundary line response of rice yield to soil properties was represented well by Mitcherich equation (negative exponential equation) that was used to quantify the influence of soil properties on rice yield, and then the Law of the Minimum was used to identify the soil limiting factor for each grid. This boundary line approach using five stable soil properties as limiting factor explained an average of about 50~% of the spatial yield variability. Although the determination coefficient was not very high, an advantage of the method was that it identified clearly which soil parameter was yield limiting factor and where it was distributed in the field.

논 재배에 적합한 콩 품종을 선발코자 황금 콩 등 국내 육성 37개 콩 품종을 공시하여 품종간 생육반응과 수량성의 차이를 조사한 결과는 다음과 같다. 1.토양수분함량이 높은 논에서의 콩 재배 시 생육단계별 콩 품종별 주요형질의 생육반응은 매우 다양한데, 특징적인 생육반응은 초기생육이 지연되거나 지하부의 발달이 늦은 반면 지상부가 과번무하여 T/R율이 높아지는 경향이 있으며, 품종간 수량성에 있어서도 팔도콩이 134kg/10a 그리고 도레미콩이385kg/10a 차이가 매우 컸다. 2. 생육초기인 V5 stage와 개화성기인 R2 stage의 엽면적은 지상부 및 지하부 건물중과 각각 고도의 상관관계 (r=0.46**~~0.91**) 를 보였으며, T/R율의 경우 V5 stage에는 지하부 건물중과 부의 상관관계(r=-0.37*) 를 보인 반면 R2 stage에는 엽면적(r=0.46**) 과 지상부 건물중(r=0.65**) 과 유의성 있는 상관 관계가 성립되었다. 3. 수량성은 100립중과 상관관계를 보인 반면 등숙율 포함한 V5 및 R2 stage에서 조사된 다른 형질과는 유의성 있는 상관을 보이지 않았다. 4.농업적 주요형질의 생육반응을 기초로 군집분석 한 결과 공시품종들은 크게 3개 군으로 구분되는데,동일 군의 품종들은 생육습성 등 유전적 유사성은 높았으나 수량성은 다양하였다. 5. Group 1에는 새올콩등 9품종이 포함되는데, 생육초기부터 개화성기까지의 생육이 늦은 반면, T/R율이 낮고 등숙이 양호하여 평균 257kg/10a의 수량성을 보인다. Croup 2는 팔도콩 등 12품종이 포함되는데, 지상부의 생육이 과번무하여 T/R율이 높고 등숙이 불량하여, 평균 230kg/10a의 수량성을 보였다. Croup 3에는 진품 콩 등 16품종이 포함되는데, 대부분 중만생종이며, V5~~R2 stage의 생육이 왕성하고 T/R율은 비교적 낮고, 등숙울 또한 비교적 높아 평균 수량성이 270kg/10a로 가장 높았다. 6. 본 연구결과를 토대로 Group 3에 속하는 품종 또는 301~~385kg/10a 의 높은 수량성을 보이는 신팔달콩2호, 소호콩, 도레미콩, 금강콩, 부광콩, 다장콩 및 검정콩2호 등의 품종을 선별하여 재배한다면 논의 적정 경지면적 유지에 의한 국내 쌀 수급안정 및 안정적인 콩 자급율 향상을 기대할 수 있을 것이다.

콩의 논 재배시 생육반응은 밭에서와는 다른 결과가 예상되므로, 논재배 콩의 휴립조건에 따른 생장분석을 분석 하고자 화엄 풋콩 등 5품종을 고휴와 평휴로 재배하여 생육반응을 분석한 결과는 다음과 같다. 휴립조건에 따른 콩의 지상부 생육은 경장의 경우 전 생육기에서 평휴재배시 높은 경향을 보이지만, 분지수와 경직경은 생육 후기로 갈수록 고휴조건에서 큰 경향을 보였다. 그러나 지상부 생육은 재배조건에 따른 차이보다, 품종간 차이가 보다 뚜렷하게 나타났다. 논에서 휴립 조건에 따른 생육단계별 콩의 지상부생육은, 생육초기인 V5 stage에서는 평휴재배시 건물 생산능력이 고휴재배시 보다 높았으나, 생육이 진전될수록 고휴로 재배할 때 건물중 생산이 높았으며, 전 생육기간 동안 품종별 차이가 뚜렷하였다. 재배조건에 따른 콩의 논에서의 지하부의 생육은, V5, R2 및 R5 stage 등 전 생육기간동안 고휴 재배시 지하부의 생육이 평휴재배조건 보다 왕성하였으며, 재배방법에 따른 고휴재배 효과는 나타나지 않았으나, 품종간 차이는 컸다. T/R율은 평휴로 재배할 경우 높았고, 재배방법에 따른 고휴재배 효과는 나타나지 않았으나, 품종간 차이는 인정되었다.
