DOI : 10.5333/KGFS.2003.23.1.001
This study was determined to the growth characteristic, yield and chemical content of Azuki bean(Vigna angularis W.F.
) based on five phosphate rates (0, 40, 50, 120, 160, 200kg/ha) from May, 2002 to August, 2002 in Jeju province. Plant height was 80.7cm at 0kg/ha of phosphate level md, as phosphate rates were increased to 160kg/ha and 200kg/ha, lengthened 88.8cm and 88.9cm, respectively, but between the two phosphat levels were no significance(P＞0.05 or 0.0l). Numbs. of branches and leaves per plant, stem diameter, and weight of leaves and stems per plant were the same response with plant height. Fresh forage, dry matter, crude protein, and TDN(total digestible nutrient) yield at the control were 23.8MT/ha, 3MT/ha, 0.5MT/ha and 1.8MT/ha, respectively, at the 200kg/ha plot were 47.3MT/ha, 7.2MT/ha, 1.3MT/ha, and 4.7MT/ha, respectively, as phosphate rate was increased. As phosphate rate increased from 0kg/ha to 200kg/ha, the content of crude protein, crude fat NFE(nitrogen free extract) and TDN increased 15.2%~18.6%, 3.4%~4.5%, 41.4%~45.5% and 58.3%~65.5%, respectively, whereas the content of crude fiber and crude ash were decreased 31.5%~24.8% and 8.1%~6.6%, respectively.

This study was conducted at a volcanic ash soil in the Experimental Farm of Cheju national university from May 1, 2000 to August 25, 2000 to determine the optimum frequency of split N application for. forage production of Jeju Italian millet(Setaria italica Beauvis). N .rate was applied with 200kg N/ha, and frequencies of the split application were 1. 2, 3, 4 and f times. Days to heading was 87 days in the N applied plot all at once, was delayed to 93 days at the five times split-applied plot. Plant height was the greatest (143cm) at the four times split-applied plot, but above o. below that was short. Leaf length, number of leaves and nodes were a similar tendency to plant height. SPAD(Soil Plant Analysis Development) reading values rose 34.3∼36.2 as N was split-applied from one to five times. Fresh forage, dry matter, crude Protein and TDN yield at the H split-applied to four times increased 33.08∼5l.50MT/ha, 9.94∼13.36MT/ha, 0.93∼1.70MT/ha and 5.06∼7.28MT/ha, respectively, but at the five tines split-applied plot decreased to 49.33MT/ha, 12.69MT/ha, 1.65MT/ha and 6.98 MT/ha, respectively. As the increasing of N split-applied. crude protein, crude fat NFE and TDN content increased 9.4∼13.0％, 1.5∼l.9％, 44.5∼45.5% and 50.9∼55.0％, respectively, whereas crude fiber and crude ash content decreased 35.3∼31.6% and 9.3∼8.3, respectively.

The effect of rare earth(RE) at three difference levels of nitrogen on the growth and nitrate content of chicory (Cichorium intybus L.) were studied in terms of leaf size, fresh and dry weight increase, and chlorophyll and nitrate content grown in plastic pots within glasshouse. Leaf size was enlarged as the level of nitrogen applied was high, and leaf within, length, and thickness of leaf were increased by RE treatment showing significant difference at high nitrogen(N+1) plot. As the level of nitrogen applied was high, as fresh and dry weight per plant was increased significantly(p<0.05), and sprinkling cabbage with RE increased fresh and dry matter yield to 2∼12, 4∼6.2% more, respectively. Dry matter content of Chinese cabbage was increased by RE sprinkling. At all levels of nitrogen fertilized chlorophyll contents were increased by RE treatment. As the level of nitrogen was high, as the content of chlorophyll was highly increased by RE. Nitrate was accumulated more at high level of nitrogen application, but nitrate was decreased by RE application, 40% decrease at very high nitrogen plot(N+2). RE stimulated the growth of chicory with high chlorophyll content, and showed the possibility producing high quality agricultural products low in nitrate content.

This study was conducted to determine the effect of seeding times and mixture rates of oat and forage rape on the growth characteristics and forage yields during rest periods from March to June after the harvest of potatoes in potato cultivation fields located in the areas about 600m above the sea level in Jeju. The experiment was a split plot desist with seeding times(early, middle and late March) sown . at intervals of ten days from early March to late March as the nam plots and mixture rates as subplots, consisted of oat single(150kg/ha), forage rape single(15kg/ha), oat/rape mixtures 75 : 25% (112.5kg/ha of oat and 3.75kg/ha of rape), oat/rape mixtures 50 : 50％(75kg/ha of oat and 7.5kg/ha of rape) and oat/rape mixtures 25 : 75％(37.5kg/ha of oat and 11.3kg/ha of rape). The germination and establishment of eat and rape were not significantly different among seeding times and mixture rates. The plant heights were higher when seeded middle March compared to seeding times of early and late March. The growth stage of the oats seeded early March was dough stage, while that of oats seeded middle or late March was milk stage. The dry matter yields per ha were higher(p<0.05) when seeded middle March than those of seeding time of early and late March. The crude protein contents of rape single, mixtures and oat single treatments were 15.9, 12.4∼14.5 and 8.5％, respectively.
