A wide diversity of liquid fertilizers and composts produced from the livestock manure in Korea is commonly applied to agricultural lands as an alternative of chemical fertilizers. However, their effects on the crop production and environmental impacts are still vague. The current study was conducted to understand the effects of the pig manure-based liquid fertilizer on the growth of Zea mays L. and soil properties. Four different liquid fertilizers were treated to each cultivated upland plot located in Gyeong-gi province, Korea while no fertilizer (control A) and a chemical fertilizer (control B) were treated to separate plots for comparison. The liquid fertilizer treatment did not make a significant difference in the fresh weight of Zea mays L. compared to the controls. This is probably due to the nutrient residues carried over from the last year fertilization. Electric conductivity (EC) and organic matter contents in soils were increased right after the liquid fertilizer treatments compared to the controls. However, soil pH was maintained as the same as the level of control A. A long-term effect of the continuous treatment of the manure based liquid fertilizer will be carried out in the successive study.

pRLYS1 containing intact rbcL gene of maize (Zea mays L. cv Golden X Bantam T-51; Zm-A) was digested with several restriction enzymes to construct subcones carrying promoter region of rbcL. The DNA fragments of 0.20, 0.19, 0.92 and 1.55 kb among the EcoRI digests, the EcoRI-DdeI digests, the AvaI digests and the EcoRI-BamHI digests of pRLYS1 were subcloned into pBluscriptSK＋and named pRLPS2, pRLPS3, pRLPS14 and pRLPS35, respectively. Four subclones contain the 1.92 kb portion from 136 nucleotide downstream to 1780 nucleotide upstream from the ATG initiation codon of rbcL gene. pRLPS2 (-29 to -229) and pRLPS3 (-239 to -420 from the ATG) were sequenced. When nucleotide sequence of Zm-A was compared with sequence of rbcL promoter region of a different cultivar of maize (Zea mays L. cv WFG TMS X BS7; Zm-B), the difference rate between two cultivars was 4.3%. The mean of sequence divergence between Zm-A and three grass species in the same tribe, Andropogoneae, in the upstream region from 29 to 420 of ATG was 1.8%, whereas between Zm-B and above-mentioned three species was 5.4%. Therefore, Zm-A seems to evolutionarily closer to three other species in Andropogoneae tribe than Zm-B is.

Several kinds of medicinal plants are used as diuretics in folk medicines and oriental drugs. The diuretic action of water extracts of the ten kinds of crude drugs, such as Pachyma hoelen $R_{UMPHIUS}$ Zea mays L., Akebia quinata $D_{ECAISNE}$, Alisma orientale Juzepezuk, Atractylodes koreana $N_{AKAI}$, phytolacca americana L., Achyranthes japo-nica $N_{AKAI}$, Juncus decipiens $N_{AKAI}$, Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$ was examined in mouse and compared with aminophylline as a control the following results were obtained. The urine volume was found to be remarkably increased by the Pachyma hoelen RUMPHIUS, Phytolacca americana L., Prunella asiatica $N_{AKAI}$ and Artemisia capillaris $T_{HUNBERG}$, moderately increased by the Akebia quinata $D_{ECAISNE}$, Achyranthes japonica $N_{AKAI}$ and Juncus decipiens $N_{AKAI}$, and slightly increased by Zea mays $L_{ENNE}$, Alisma orientale $J_{UZFPEZUK}$ and Atractylodes koreana $N_{AKAI}$.

The growth characteristics and yield per unit area of two cropping systems, corn monoculture and 'wrnsoybean intercropping, were compared and the obtained results were as follows; 1.The two cultivation systems were not significantly different in leaf length, leaf width and length of internode at harvesting time. 2.The weight of stalk and the leaves of a plant were decreased with maturity, while the weight of ear was markedly increased. The patterns of relative ratio of each components were essentialy same in each cultivation systems. In corn monoculture, the percentages of stalk, leaf, and ear at final harvesting stage were 22.9, 13.7, and 63.4 and in corn-soybean intercropping, they were 21.8, 10.9, and 67.3 respectively. 3.Dry matter yield per unit area (kg/lOa) of intercropped corn at yellow stage was similar to that of monocultured corn (1, 483 kg/ 10a vs 1, 509 kg/ 10a). At ripe stage, however, the dry matter yield of intercropped plant was more than that of monocultured (1, 679 vs 1, 660 kg/ 10a). 4.The same pattern was observed in organic matter yield.

This study was designed to investigate the effects of antagonistic microorganism, Bacillus subtilis, on the growth of forage seedlings in repeated cultivation soils and unrepeated cultivation soils. The field experiment was wnducted in pots in a vinyl house using repeated and unrepeated cultivation soils. Forage types were 'Suwon 19' wrn(Zea mqs L.), 'Califbmia' white clover(Tr~oIium repens L.) and 'Fawn' tall fescue (Festuca arundianacea Schreb.). Samples of white clover and tall fescue were taken h m each pot at 36 days after seeding. Samples of wm were examined at 50 days after seeding. The most active antagonistic bacterium was isolated h m forage rhizosphere soil, and selected by reference to it's antagonistic ability on the growth of pathogenic fungi, Rhizoctonia solmi and Fusarium oxyspomm, and it was identified as Bacillus subtilis. This strain strongly suppressed the growth of fungal pathogens among isolated rhizobacteria. The dry weight of forage shoots and roots cultivated in unrepeated cultivation soils was higher than that cultivated in repeated cultivation soils. The dry weight of forage was positively affected by the inoculation of the antagonistic bacterium, Bacillus subtilis, in both repeated cultivation soils and unrepeated cultivation soils. In conclusion, the growth of forage was more affected by the inoculation of the antagonistic bacterium in unrepeated cultivation soils than that in repeated cultivation soils, and bacterization of forage with B. subtilis resulted in an inrreased yield.

Effects of addition of soil ameliorants on the growth and nutrient absorption of Zea mays, Miscanthus sinensis and Phytolacca americana were investigated. Acid soil from Yeocheon Industrial Complex were used for the control plot (AS). We made two treatment plots, acid soil + lime (AS + L) and acid soil + dolomite (AS+D). Ration of acid soil : soil ameliorants in freatment plot was 50 : 1(V:V). Acid soil and soil ameliorants were mixed thoroughly before use. Shoot length of corn in AS+L and AS+D was considerably increased by 141% and 137%, respectively, compared with that in AS. Pokeweed in AS+L and AS+D also increased by 183% and 152%, respectively, compared with that in AS. However, growth of Miscanthus sinensis showed slight difference between the control and the treatment plots. Biomass of corn and porkweed in the treatment plots were also greater than those in the control plots. During the growth experiment with corn, concentrations of Ca and Mg in soil were increased and A1 decreased with increased soil pH in the treatment plots. Amount of aluminum absorbed by corn in the control plot was greater than that in the treatment plots. In case of Miscanthus sinensis, however, aluminum absorption in the control plot was lower than those in the treatment plots.
