  • "Hwangkeumbora" is a new japonica rice cultivar developed from a three way cross of Jinbubyeo, Odaebyeo, Fukei126 at Honam Agricultural Reaserch Institute (HARI), NICS, RDA, in 2006. This cultivar has about 110 days growth duration from transplanting to harvesting under Korean climate condition. The milled kernel of "Hwangkeumbora" is translucent with non- glutinous endosperm. Amylose content of "Hwangkeumbora" is about 19.3%. "Hwangkeumbora" has better palatability of cooked rice compared with "Odaebyeo" and shows high resistant reaction to the blast, but susceptible to major diseases and insect pests. The milled rice yield of "Hwangkeumbora" is about 5.37 MT/ha under the standard fertilizer level of the ordinary transplanting cultivation. "Hwangkeumbora" would be adaptable for ordinary transplanting in northern plain, mid-mountainous, southern mountainous of Korea.

  • 'Sinunbong 1' is a japonica rice cultivar developed from the cross between "Sangjubyeo", high yield cultivar and 'Unbong 17', cold tolerance at Honam Agricultural Research Institute (HARI), NICS, RDA, in 2005. This cultivar has a short grain shape and about 111 days growth duration from transplanting to harvesting in Korean climate condition. This cultivar shows high resistant reaction to the blast, but susceptible to bacterial blight and strip virus. This variety has cold tolerance, compared to Odaebyeo. The milled kernels of 'Sinunbong 1' are translucent with non-glutinous endosperm. It has about 19.2% of amylose content and better palatability of cooked rice compared with 'Odaebyeo'. The milled rice yield of 'Sinunbong 1' is about 5.46 MT/ha under the standard fertilizer level of the ordinary transplanting cultivation. 'Sinunbong 1' would be adaptable to the northern plain, mid-mountainous, southern mountainous of Korea.

  • This study was conducted to find out the optimum nitrogen application rate for the stable production of rape in the newly reclaimed land located at Gangwhal region of Saemangum reclaimed land in which the soil is sandy loam (Munpo series). There were five treatments of nitrogen fertilization from zero to 60% increment based on the standard fertilization of $150kg\;ha^{-1}$. The growth of rape (Sunmang) was not affected by salt content while soil salinity was increased at blossoming season of rape. Compared to yield of standard fertilization the yield and the content of oleic acid of rape were increased by 4~26% with the increasing additional nitrogen fertilizer. The results obtained from the growth and yield of rape in this study indicated that it was possible to cultivate rape in a newly reclaimed land if soil salinity was kept below $3dS\;m^{-1}$.
