Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 79~88
This experiment was conducted from May to August in 1997 to selected the wrn hybrids being suitable for silage at farm in the Kongju National University through the comparison of growth characteristics, forage yield and growth analysis about native and imported corn hybrids for silage production. In this experiment, trial design was a randomized block design with three replication, testing varieties were 4 hybrids (Suwon 19, Kwanganok, Whengsungok, Suwonok ) of native corn hybrids and 13 hybrids (P 3156, P 3352, P 3144w, DK 501, DK 689, DK 713, DK 729, H 643.99, H 545.64, H 645.12, HC 7466, H 644.18, H ALISEO) of imported corn hybrids. The results obtained are summarized as follows; 1. The emergence rate of H643.99 was the highest with 97.0%. In rice black streaked dwarf virus(RBSOV), the hybrid of HC 7466 was lower infected with 1.6% than other hybrids. The plant hight of P 3144w was the highest with 339 cm and the stem length of P 3156 was the highest with 261 cm. In native com hybrids, the plant height and stem length of Kwanganok were recorded with 306 cm and 235 cm, respectively. 2. Leaf number and leaf area of Kwanganok were the greatest with 16 sheet per plant and
, respectively. H 645.12 and H 545.64 had the greatest in ear to total dry matter ratio with 49.5% and 49.4%, respectively. 3. The fresh matter yield was significantly difference between growth stage, So Suwon 19 had the most level at 15 days before silking, P 3352 had the most level at silking date, Kwananok had the most level at 35 days a after silking. The fresh matter yield of native com hybrids such as Suwon 19 and Kwanganok was not apparent diffreences as compared with imported corn hybrids. 4. As the results of survey with dry weight, the quantity of dry matter accumulation were increase after silking. The varieties of P 3352, P 3156, Kwanganok, OK 713 were more quantity of dry matter production than DK 501, HC 7466. The Kwanganok of native com hybrid and Pioneer strain with high percentage of dry matter were higher dry weight than Limagrain strain. 5. HC 7466 had the largest LAR with
, H545.12 had the lowest LAR with
. P 3144 had the largest LAI, DeKalb strain including DK 713 were larger apparently than Limagrain strain including HC 7466 with 3.15. 6. The RGR of testing varieties was little difference of statistical significantly, but DK 501, and HC 7466 were lower than other corn hybrids. The CGR of native and American varieties was no apparent differences, but that of Limagrain strains were a large variation. According to the results obtained by this experiment, the eary growth such as emergence rate and RBSDV infection rate of Limagrain strains was more excellent than other strains. P 3156, P 3352, P 3144w, DK 713 and HC 7466 were suitable for silage condition such as dry matter yield, percentage of dry matter and % ear to total dry matter. The fresh and dry matter yield of native corn hybrids such as Suwon 19 and Kwanganok were not apparent differences as compared with imported corn hybrids, but percentage of dry matter was lower than other imported corn hybrids.
Effect of Chemical Drying Agents on the Field Drying Rate of Alfalfa and Rye Hay
Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 89~94
A field experiment was carried out to determine the effects of chemical drying agents at mowing on the field drying rate of alfalfa (cv. Vernal) and rye (cv. Koolgrazer) for hastening hay manuf8cture. In alfalfa; chemicals (
, 1% only water spray and control) were treated at early bloom stage in 1995. Chemicals (
, 2% and control) were applicated at different harvest stages (early heading, heading and bloom) in rye, 1996. The drying rate of alfalfa by
treatment among chemicals was higher than control, and the duration of field dry was shortened by one day with
application, but there was no difference in drying efficiency between
3%. In rye, however, no moisture reduction by chemicals was observed. The days required for field dry were 6, 4, and 3 days at warly heading heading and bloom stage respectively; regardless of chemical drying agents and conbol. The nutritive value of rye hay with chemicals at baling was very slightly higher than control, but there was no significant difference. Also, no difference of hay quality was found among drying agents. In conclusion,
can enhance the field drying rate of alfalfa hay, but the drying efficiency was not high, particularly in rye hay. Harvesting at early heading to heading stage was desirable for manufacture of high quality rye hay.
Short-Term Effect of Mineral Nitrogen Application on Reed Canarygrass (Phalaris arundinacea L.) in Uncultivated Rice Paddy
Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 95~106
A study was made to estimate the economic level(Necon.) of mineral nitrogen and a cutting frequency for the dry matter production of reed canarygrass(Phalaris arundinacea L.) in uncultivated rice paddy during the harvested years in 1993~1995. Annual mineral nitrogen was applied at the levels of 0, 90, 180, 270 and 360 kg
in 3 cuttings, 0, 120, 240, 360 and 480 kg
in 4 cuttings, and 0, 150, 300, 450 and 600 kg
in 5 cuttings, respectively. The results were summarized as follows; 1. The dry matter yields of all cutting frequencies in 1993 were significantly higher than in the other hay years. Mean dry matter yield were 14.40, 13.88 and 15.98 tons
in 3, 4 and 5 cuttings, respectively. 2. Significantly higher matter yields were obtained as 15.37 and 15.80 tons
at the level of 120 kg
in 3 and 4 cuttings, and 14.02~14.08 tons
levels of 90~120 kg
in 5 cuttings, respectively. 3. Higher efficiencies of dry matter production in response to mineral nitrogen application were recorded as 29.7 kg at level of 90 kg
in 3 cuttings, 19.6 kg at level of 240 kg
in 4 cuttings, and 20.1 kg at level of 150 kg
in 5 cuttings, respectively. 4. Significantly higher matter yields appeared as 5.02 tons
at 2nd cut in 3 cuttings, 3.94~4.37 tons
at 2nd and 3rd cut in 4 cuttings, and 3.81~3.58 tons
at 2nd and 3rd cut in 5 cuttings, respectively. 5. The highest values of relative dry matter yield were 40.4% for 2nd cut in 3 cuttings, 34.9% for 3rd cut in 4 cuttings, and 31.5% for 2nd cut in 5 cuttings, respectively. 6. The estimated marginal dry matter yields(Ymar.) were 13.8~14.7 tons
at ranges of economic N level of 228.5~291.9 kg
in 3 cuttings, 13.8~14.2 tons
at ranges of 293.5~335.7 kg
in 4 cuttings, and 12.2~12.8 tons
at ranges of 237.5~302.5 kg
in 5 cuttings, respectively. 7. Maximun dry matter yields(Ymax.) were 17.0 tons at the level of limiting N(Nmax.) of 558.9 kg
in 3 cuttings, 16.1 ton at level of limiting N of 531.4 kg
in 4 cuttings, and 13.9 ton at level of limiting N of 546.3 kg
in 5 cuttings, respectively. 8. Economic N level in all cuts were in the ranges of 42.6~123.8 kg
in 3 cuttings, 27.3~144.1 kg
in 4 cuttings, and 9.3~159.4 kg
in 5 cuttings, respectively. 9. The proper cutting frequency for matter production of reed canarygrass was 3 cuttings during the h harvested years in 1993~1995, due mainly to the higher efficiency of N for the dry matter production.
Effects of Herbicide Application Method on Abutilon avicennar Control and Corn Yield
Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 107~112
This experiment was carried out to investigate effects of herbicide application method on Abutilon avicennae control and corn yield at the forage experimental field, grassland and forage crop division, National Livestock Research Institute, RDA, Suwon from 1996 to 1997. The experiment was arranged in a randomized block design with three replication. The herbicide application consisted of control, 2-3 leaf stage(Dicamba), 5-6 leaf stage (Dicamba) and soil treatment(Pendimetha1in). The hybrid of corn used in this experiment was P 3352. The results obtained are summarized as follow; 1. The plant and ear height was the lowest at control. Tasseling and silking date were delayed 3-4 day at control. The length and weight of ear were the highest at Dicamba treatment in 2-3 leaf stage. 2. The herbicide injury of corn was detected slightly after 10-20 day but the injury was recovered soon. The weed control efficiency was 96.7 and 81.8% at Dicamba treatment in 2-3 and 5-6 leaf stage, respectively. 3. The fresh and dry matter yield of Dicamba treatment in 2-3 leaf stage was higher than that of control by 36%, but no significant difference was found among herbicide application method. 4. Herbicide application method had little effect on the ADF, NDF and CP contents, but the CP and IVDMD of ear were higher than that of stover. The results of this experiment indicate that the application of Dicarnba in 2-6 leaf stage of corn will remove almost all of A butilon avicennae and increase DM yield of corn.

This experiment was conducted to establish the cultural method of triticale(Triticum Secalotriticum Saratoviense Meister) as a whole crop silage by evaluating the effect of seeding date and nitrogen fertilization rate on forage yields and feeding value. Heading date, flowering date, and the dough stage of development came significantly earlier as triticale was seeded earlier. Soilage, dry matter yields and percent dry matter significantly varied with seeding dates and crude ash, NFE and TDN. However, TDN yield was significantly reduced by delayed seeding. Macromineral contents were not affected by seeding date. Soilage, dry matter yield, and percent dry matter significantly increased as nitrogen fertilization rate increased. The contents of crude protein, crude fat, crude ash, NFE, TDN and TDN yield also significantly increased. In contrast, crude fiber content of triticale decreased with increasing N fertilization rate.
Study on No-tillage Silage Corn Production with Legume Hairy Vetch (Vicia villosa Roth) Cover II. Changes of yield and nitrogen upake of corn by N fertilizer and hairy vetch cover
Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 123~128
Legume winter cover crop hairy vetch(Vicia villosa Roth, HV) can supply mineral nitrogen for silage corn by HV cover killed. The purphose of this study was to understand changes of soil mineral N, yield and N uptake of silage corn by N level (0, 135kgFN/ha) and cover cmp(no cover crop: NCC, hairy vetch cover crop: HVC) at field of Crop Experiment Station in 1996. HV growth decreased soil mineral N concentration before seeding corn, but killed HV cover increased concentration of soil mineral N at surface soil (0~7.5cm) at six-leaf stage of corn. Total dry matter(DM) and N uptake of corn averaged over N level was more decreased in HVC than in NCC at silk stage, but N uptake of corn after silk was more increased in HVC than in NCC by N mineralized fiom HV killed, especially in OkgFNJha. N fertilization increased total DM and and N uptake of corn averaged over cover crop, especially more increased the DM and N uptake before silk stage. Early application of N fertilizer was recommendable in netillage silage corn using hairy vetch cover crop.

Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 129~132
Birdsfoot trefoil grows wild in some parts of Korea, but specific information is lacking as to its growth characteristics, nutritive value and dry matter production potential. The objective of this study was to evaluate the usefulness of wild birdsfoot trefoil(Lotus cornicubus L.) as a forage. Wild birdsfoot trefoil and Au Dewey were field sown at Keongsan, Keongbuk in the spring of 19%. Emergence for Au Dewey was better than for wild birdsfoot trefoil. It was observed that the flowering date of the wild birdsfoot trefoil was similar to Au Dewey. Regrowth of Au Dewey was better than that of the wild birdsfoot trefoil at each harvesting. AAer the last harvesting date, October 1, there was no regrowth of the wild birdsfoot trefoil, but regrowth of Au Dewey measured IOcm. Weed infestation in the wild birdsfoot trefoil plots was higher than in the Au Dewey plots. The dry matter yields were significantly(P< 0.05) higher for Au Dewey than for the wild birdsfoot trefoil.

Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 133~142
This study was conducted to investigate the effects of antagonistic bacteria and pathogenic fungi on the growth of tall fescue(Festuca arundinacea Schreb.) in continuous cropping soil(CCS) and non-continuous cropping soil(NCCS). Tall fescue was established by seeding into pots of 11 cm in diameter and 9 cm in depth containing 1 : 1 mixture of soil and vermiculite, and cultivated at pots with antagonistic bacteria and pathogenic fungi in a vinyl house. The bacteria used in this study were Bacillus subtilis and hsants. B. subtilis was isolated and identified kern forage rhizosphere soil and fusants were isolated through cell hsion from B. subtilis and B. thwingiensis. B. subtilis was named as B. subtilis 101 and hsants were named as F-3, F-7 and F-8. In dark culture experiment, tall fescue inoculated with the antagonistic bacteria lived longer than that of control in both CCS and NCCS. However, tall fescue of CCS lived shorter than that of NCCS. Dry weight of tall fescue inoculated with the antagonistic bacteria was higher than that of tall fescue inoculated with pathogenic hngi in both CCS and NCCS(P< 0.05), and the antagonistic bacteria showed positive effects on the growth of tall fescue. However, Dry weight of tall fescue was decreased by the inoculation of the pathogenic b g i in both CCS and NCCS(P< 0.05).

Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 143~150
Six field bean (GI-vcine soza S and Z ) plants were examined for their genetic polymorphisms and intraspecific variations using randomly amplified polymorphic DNA(RAPD) markers. In RAPD analysis of 5 random primers (Rp-1, Rp2, Rp-3, Rp-4, Rp-5), 30 of total 155 bands obtained kom 5 primers were polymorphic and sizes of polymirphic band ranged between 0.5 and 3.0 kb. Number of bands amplyfied per primer was varied from 2 to 11 and average number was 6.0. Genetic variation of intraspecies in the samples of six region was ranged behveen 11 to 25 percent, and genetic similarity among intraspecies was ranged from 0.69 to 0.78. In pairwise genetic similarity test of six field bean plants, Mun and Hoj showed highest coefficient of genetic similarity as 0.67, whereas Sin and Hoj was lowest as 0.45. According to the genetic similarity, the level of intraspecific variation is higher than that of regional distance in GI-vcine soza.
A Comparative Study on the Nutritive Value of Festulolium braunii ( Fstuca pratensis Huds.
Lolium multiflorum Lam. )
Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 151~156
This study was conducted to evaluate the forage yield and quality of Fesrulolium bmunii(Festuca prafensis Huds. x Lolium multiflomm Lam.) as a forage sources. The experiment was arranged in a randomized block design with four replications from Sep. 1995 to May 1998 at Chungnam University. Treatments consisted of two forage species, Festulolium bmunii(Pau1ita) and Dactylis glomerc;d4Potomac). The dry matter yields, nutritive value, N and energy balance were observed. The yields of DM, CPDM and DDM per area(ha) were higher for Potomac (P< 0.01) than for Paulita. The content of CP showed no difference between Potomac and Paulita, but NDF, ADF and lignin contents of Paulita were absolutly lower than those of Potomac (P<0.05). The retained N and energy were also high for Paulita compare to for Potomac. It could be suggested that Paulita has higher potential for improvement of the forage quality than Potomac and it have a potential to provide as a forage sources.

Journal of The Korean Society of Grassland and Forage Science, volume 18, issue 2, 1998, Pages 157~162
This experiment was carried out to investigate the effects of harvesting date and additives on the quality of fall sown oat(Avena sativa L.) silage at the department of animal resources science, college of life resources science, Woosuk University, Wanju &om August, 1997 to March, 1998. The experiment was arranged in a split plot design with three replications. The main plots consisted of the harvesting date such as 15 Oct., 23 Oct. and 2 Nov. and different additives as subplots(control, wheat bran, formic acid, lactic acid bacteria, and wilting). The results otained are summarized as follow : The fiesh and dry matter yield of oat were increased by harvesting date delayed, then fiesh and dry matter yield at 2 Nov. were highest as 36,733 and 7,29Okg/ha, respectively. The dry matter content of oat silage was increased significantly by harvesting date delayed(P< 0.05), and DM content of wheat bran and wilting treatment was high at every harvest date. The DM loss was lower in LAB, formic acid and wheat bran treatment, but on significant difference was found among harvesting date(P< 0.05). Average pH of silage harvested at 23 Oct. was lowest as 4.06, and the quality(CP, NDF, ADF, and IVMDM) of oat silage was decreased by harvesting date delayed. The content of acetic acid was no difference among harvesting date, but butyric acid was decreased and lactic acid was increased at 23 Oct. harvest. The result of this study indicate that oat harvested at booting-heading stage of maturity with wilting wheat bran, and LAB could be recommended as producing high quality of oat silage.
