Train of chemical and biological processes was investigated to treat leachate from industrial waste landfill. Organics and nitrogen concentrations of landfill leachate studied in this research were high and their BOD/COD ratio was 0.3. Biological process should be combined with chemical process for optimum treatment of leachate. PAC(Polyaluminium chloride) was the best coagulant among three chemicals tested, and the optimum condition of PAC coagulation was pH 6 and 1,250 mg/L of dosage. When SBR was operated for simultaneous removal of organics and nitrogen, removal efficiency of COD and T-N reached over $82\%,\;71\%,$ respectively and time distribution of 2/4/2/1 was most effective for one cycle of anoxic/aerobic/anoxic/aerobic.

This study was carried out to investigate the optimum application time of basal fertilization in direct-seeded rice on flooded paddy surface at medium saline soil in southwestern reclaimed saline area which is Munpo series and have 0.3 or more soil salinity. The nitrogen fertilizer level were 14, 17, 20kg per 10a, and the basal fertilization were applied before sowing, 10, 20, 30 days after sowing along with topdressing at tillering stage, respectively. The summarized experimental results are as follows. Seedling stand was proper when basal fertilization was applied before sowing, but lower than appropriate seedling stand when basal fertilization were applied 10, 20, 30 days after sowing along with topdressing at tillering stage. The rice yield were 509-541kg/10a when 14-20kg/10a basal fertilization was applied before sowing, and 368-481kg/10a when basal fertilization were applied 10, 20, 30 days after sowing along with topdressing at tillering stage. Considering the yield and salt injury at medium saline soil in southwestern reclaimed saline area, the application of basal fertilization before sowing was superior for improving seedling stand, and 14-20kg/10a fertilization rate was allowable.

This study was carried out to investigate the proper interval of water exchange according to nitrogen fertilizer level at medium saline soil which are 0.3 or more soil salinity in southwestern reclaimed saline land. The nitrogen fertilizer level were 14, 17, 20kg per 10a, and the interval of water exchange were every 3, 6, 9 days after transplanting. The summarized experimental results are as follows. The salinity were maintained as low when the interval of water exchange were every 3 or 6 days after transplanting, but salinity was highest at rooting stage, and decreased from that, so salinity were about 0.3 at panicle initiation stage or ripening stage when the interval of water exchange was every 9 days after transplanting. The rice yield were 537-552kg/10a when the interval of water exchange was every 3 days with 17-20kg/10a nitrogen fertilizer level, and 519-533kg/10a when the interval of water exchange was every 6 days with 17-20kg/10a nitrogen fertilizer level, but decreased outstandingly in the other treatments. Considering the yield and salt injury at medium saline soil at southwestern reclaimed saline land, proper nitrogen fertilizer level was 17-20kg/10a when the interval of water exchange were every 3 or 6 days after transplanting.

Field experiment was carried out to identify the optimum time of basal application of nitrogen in Southwestern reclaimed saline land. Nitrogen application before seeding and 10, 20 & 30 days after seeding were evaluated with three nitrogen application levels(140, 170 & 200 kg/ha) in Munpo soil series having 0.1~0.2% of soil salinity. Nitrogen was split-applied with forestage; basal, tillering stage, flowering initiated stage and ripening stage by a ratio of 50-20-20-10%. Results reveled that seedling stands were considerably higher when basal nitrogen applied before seeding as compared to after seeding. Grain yield increased with increase of nitrogen application before seeding. Grain yield was the highest when nitrogen application was 170~200 kg/ha before seeding. Therefore, it is recommended that the optimum nitrogen application level was 170~200 kg/ha before seeding in direct seeded rice in southwestern reclaimed saline land for maximum plant establishment and grain yield.

Boseogchal is a new japonica rice cultivar developed from the three-way cross of Hwayoung, Tamjin and Sinseonchaltransplanting to harvesting. This cultivar shows multiple resistant reactions to the bacterial blight (K1 race), leaf blast and stripevirus disease. Boseogchal yielded about 5.21 MT/ha in milled rice under the standard fertilizer level of the ordinary transplantingcultivation. Boseogchal is adaptable to the middle plain of Honam area in Korea.

Hyun-Su Park,Ki-Young Kim,Woo-Jae Kim,In-Bae Choi,Man-Gee Baek,Ki-Yong Ha,Hyun-Jung Kang,Mun-Sik Shin,Jae-Kwon Ko 한국작물학회 2010 한국작물학회 학술발표대회 논문집 Vol.2010 No.04
Currently, more than 33 resistance gene against bacterial blight(BB) have been identified and used to develop resistant cultivar. IRRI developed near isogenic lines carrying monogenic resistance gene and pyramided genes, IRBB lines. This study was conducted to identify the response of resistance gene to Korean bacterial blight races(K1, K2, K3, and K3a) in IRBB lines. Xa1(IRBB1) was resistant to K1 race and Xa2(IRBB2) was resistant to K1 and K2 race. Xa3(IRBB3 and IRBB203) exploited in many breeding programs in Korea were resistant to K1, K2, and K3 race but susceptible to K3a. Xa4(IRBB4 and IRBB204), xa5(IRBB5 and IRBB205), Xa7(IRBB7 and IRBB207) were resistant to four races. xa8(IRRR8) and Xa11(IRBB11 and IRBB211) showed same reaction of Xa2, resistant to K1 and K2. Xa10(IRBB10 and IRBB210), xa13(IRBB13), Xa14(IRBB14 and IRBB214) showed same reaction of Xa1, resistant to K1. Xa21, identified from the wild rice, Oryza longistaminata, is highly resistant to a broad spectrum of Xoo races. In this study, Xa21 was resistant to K2, K3, and K3a but susceptible to K1 widely spreading in Korea. So, Xa21 may be vulnerable to Korean bacterial blight. But pyramided lines with Xa21 showed high level of resistance to all races of Korea. Pyramided lines with Xa4 which conferred durable resistance in many commercial rice cultivar, xa5 which provides recessive resistance, and other resistance genes showed high level of resistance to Korean bacterial blight races.
