In order to develop a simple and reproducible protocol for red top bentgrass (Agrostis alba L.), effect of different growth regulators was investigated for embrogenic calli induction and subsequent plant regeneration using mature seeds. MS medium containing 2 mg/L 2,4-D was optimal for embryogenic callus induction from mature seeds. The highest plant regeneration frequency (64.4%) was showed when the embryogenic callus tissues were cultured on N6 medium supplemented with 0.5 mg/L 2,4-D and 2 mg/L BA. Regenerated plantlets were grown normally when shoots transplanted to the soil. A high-frequency and efficient regeneration system from mature seeds would be helpful for molecular breeding of new variety of red top bentgrass through Agrobacterium-mediated genetic transformation.

Seed priming is an useful technique for increasing germination and early establishment of seedlings. In this experiment, the conditions for priming of pasture seeds (tall fescue, orchardgrass, alfalfa and white clover) have been optimized to ensure an early germination and more uniform growth of seedlings. The experiment was conducted in a split plot design with three replications. The main plots consisted of four different priming duration such as 2, 4, 6 and 8 days for grass, and 1, 2, 3 and 4 days for legume. The subplots were consisted of three priming temperature such as 10, 15 and
. Effects of priming duration and temperature were different in all four pasture seeds examined. The germination of primed grass (tall fescue and orchardgrass) was the highest on 6 days in priming duration, whereas that of legume (alfalfa and white clover) was the highest on 2 days. In priming temperature, the germination of primed orchradgrass increased as decreasing temperature, however that of legume increased as increasing temperature. These results suggest that seed priming induced earlier and higher germination for all four pastures tested. However, the degree of priming effectiveness on pasture species depending on the priming duration and its temperature.

This experiment was conducted at college of Agriculture and Life Science in Chungnam National University from September, 2004 to June, 2007 in order to evaluate the mixture possibility between barley and rye in the area of Daejeon. Rye (cultivar; Koolgrazer) and barley (cultivar; Daeyeon Bori) were set for the experiment. The experiment was arranged in four treatments: R100 (rye 100%), R60 + B40(rye 60% + barley 40%), R50% + B50% (rye 50% + barley 50%), and R40% + B60% (rye 40% + barley 60%). The experiment was repeated three times in the randomized complete block. The average dry matter (DM) yield for three years of R100 weighed 9,282 kg and its DM yield was higher than any other DM yield. The higher the barley seed rates are, the lower the DM yield is (p<0.05). As the barley seed rates increased 40%, 50%, and 60% respectively, its vegetative percentage tended to increase 30%, 41%, and 47%, but the barley vegetative percentage against its seed rates did bring forth somewhat low results. Compared with R100, the contents of crude protein (CP) and in vitro dry matter digestibility (IVDMD) got higher as the barley seed rates became higher, while the contents of NDF, ADF, cellulose, and lignin were lower (p<0.05). Compared with R100, the yields of crude protein dry matter (CPDM) and digestible dry matter (DDM) showed lower in the any mixed barley (p<0.05). Thus, in case of using barley mixed with rye in the area of Daejeon, it seems to be quite difficult, unless the supply of high-productive barley variety is followed, to enhance the yields of DM, CPDM, and DDM.

This experiment was conducted to compare forage production and feed value of winter forage crops at the experimental field of Livestock Division, National Institute of Animal Science from 2003 to 2004 in Jeju. The experiment was arranged in slit plot design with three replications. Main plots consisted of two cutting times, one time cutting and two times cutting. Sub plots consisted of 5 different seed combinations, T1 (Italian ryegrass), T2 (Oat), T3 (Italian ryegrass 25+Oat 75%), T4 (Italian ryegrass 50+Oat 50%), T5 (Italian ryegrass 75+Oat 25%). One time cutting showed the highest dry matter (DM) yield by 18,680 kg/ha. Tow times cutting showed the highest crude protein (CP) content by 11.97%. The all treatments have narrow range of total digestible nutrient (TDN) from 60.6% to 70.4%.

This experiment was conducted to compare the agronomic characteristics, productivity of silage com and barley cropping, forage sorghum and barley cropping in accordance with Drainage Culvert Spacing at poorly drained paddy field in National Institute of Animal Science, at Seonghwan in Korea, March 2006 to May 2007. The emergency and flowering date were no different among treatments. Emergency rate and flowering date were 90% and July 26 in silage com, 91% and July 21 in forage sorghum, 92% and April 27 in barley, respectively. Dry matter yield was high in line with 3 m drainage culvert spacing (24,389 kg/ha) > 5 m (23,543 kg/ha) > 7 m (21,527 kg/ha) > 0 m (14,132 kg/ha). In cropping systems, dry matter yield of forage sorghum and barley (22,111 kg/ha) was higher than silage com and barley (19,684 kg/ha). Crude protein and TDN yield were high in line with 3 m (2,365 and 15,394 kg/ha) > 5 m (2,255 and 14,513 kg/ha) > 7 m (1,884 and 13,747 kg/ha) > 0 m (995 and 8,682 kg/ha). In cropping systems, crude protein and TDN (total digestible nutrients) yield of forage sorghum and barley cropping system (2,165 and 13,582 kg/ha) was higher than silage com and barley cropping system (1,576 kg/ha and 12,482 kg/ha), respectively. Consequently proper drainage culvert Spacing at poorly drained paddy field was 5 m with forage sorghum and barley cropping system.

No comprehensive tillage system of corn (Zea mays L.) has been conducted in Korea. Therefore, this experiment was carried to determine soil characteristics, weed and forage production in tillage system of corn. Plot was allotted to one of four treatments in a randomized block design using tillage system. The four treatments were (T1) conventional tillage, plow and rotary till, (T2) rotary till, (T3) disk till, and (T4) no-till system. In soil characteristics before planting and after harvest of corn, pH and organic matter at planting date was higher than at harvest date, however, there were no difference among tillage system. Days from planting to silking of no-till was the longest among tillage system. Lodging resistance of disk and no-till were higher than conventional and rotary till due to its thicken stem diameter. Main weed in corn field are barnyard grass (Echinochloa crusgall), velvetleaf(Abutilon avicennae), crabgrass (Digitatia saguinalis), and redroot pigweed (Amaranthus retroflexus). Weed population was lower in no-till than others tillage system. Dry matter (DM) content and ear percentage of conventional and rotary till were higher than others in corn field. However, DM and total digestible nutrients (TDN) yields of disk and no-till were higher than those of conventional and rotary till. Therefore, disk and no-till are more suitable in corn silage system because of high lodging resistance and forage yield, and low weed population.

This experiment was conducted to investigate the selection of regional double cropping system for production of organic forage in southern region of Korea. The species of forage crop used in this experiment were com, sorghum
sudangrass hybrid and japanese millet for summer crops and rye and Italian. ryegrass for winter crops. In organic cultivation condition, sorghum
sudangrass hybrid showed higher DM (dry matter) and TDN (total digestible nutrient) yield than that of com. Dry matter yield of com which cultivated in organic condition decreased to about 35% that of control because of weed. In winter crops, DM and TDN yield of rye is similar to that of Italian ryegrass. We could not find out the difference of nutrient value between each treatments. It means that the amount of nutrient is affected by DM productivity of each crop. The result of this study indicated that sorghum
sudangrass hybrid (summer crop) and rye (winter crop), sorghum
sudangrass hybrid (summer crop) and Italian ryegrass (winter crop) cropping system could be recommended as producing high yield of organic forage in southern region of Korea.

This study was carried out to evaluate the effect of application of cattle manure and chemical fertilizer on dry matter productivity and nutritive values of rye and hairy vetch according to two different sowing methods such as single or mixed-sowed cultivation. Dry matter and TDN yields for rye single culture, and rye and hairy vetch mixed culture were 7.2 and 4.0 ton/ha, and 8.0 and 4.4 ton/ha, respectively. They were significantly (p<0.05) higher than that (4.5 and 2.7 ton/ha) of hairy vetch single culture. Moreover, plots produced by mixed-sowing cultivation had a higher crude protein (CP) as 7.7% than that of only rye plot, and higher TDN and RFV as 55.8 and 79.4%, respectively. Within rye alone plots, completely cattle slurry application produced significantly higher annual DM and TDN yields (7.4 and 4.1 ton/ha) than those of P+K fertilization (7.2 and 3.9 ton/ha) as a chemical fertilizer and non-fertilizer (5.5 and 3.1 ton/ha). Cattle slurry application plot revealed 75.52 and 78.97% of N+P+K fertilization plot for annual DM and TDN, respectively. Within mixed-sowing cultivation with rye and hairy vetch, completely cattle slurry application produced 7.6 ton/ha DM and 4.5 ton/ha TDN, showing 79.50 and 86.77% of N+P+K fertilization plot, respectively. Furthermore, the CP content for cattle slurry plots was 8.5%, which was significantly (p<0.05) higher than those of other plots, and it was also highest in TDN (58.3%) and RFV (86). Overall, rye mixed-sowing with hairy vetch rather than rye alone sowing reduced DM yields, but leaded to enhancement of feed value and nutritive yields. And also, it would be expected that cattle slurry application in comparison with chemical fertilizers might result in reutilization of resources, improved forage quality and, extended harvest period by preventing feed value from rapidly deteriorating.

This study was conducted to investigate the effects of the type of swine manure on herbage productivity, the properties of soil and environmental pollution in mixed grassland. The field experiment was carried out on Livestock Breeding Station, Chonbuk in Korea from Nov. 2002 to Nov. 2005. Experimental plots were consisted of the types of swine manure, such as additional swine manure fermented with sawdust (SMFWS)+urea 50% and swine slurry (SS)+urea 50%. And then, chemical fertilizer (Urea) is used as control. DM yields of herbage were not different between chemical fertilizer and the type of swine manure. Feed values (CP, NDF, ADF, TDN) were not different between chemical fertilizer and swine manure treatments. After finishing with the experiment, Organic matter contents in soil increased. Organic matter, available phosphorous and Ca contents in swine manure treatment were higher than those of chemical fertilizer (p<0.05).
-N concentrations in leaching water in the mixed grassland was hardly influenced by application of swine manure and urea, whereas
-N levels in leaching water were less than 5 ppm.

This trial was conducted to investigate effects of different feeding types of conventional or total mixed rations (TMR) provision on feed intake, nutrient digestibility, nitrogen retention and blood metabolite characteristics in different breeds of native and cross bred Korean black goats. Ten Korean native male goats and 10 Korean crossbred black male goats (Korean native
Australian feral crossbred, 50:50), average 18 kg of BW, were used in this trial, and each breed of Korean black goats was separated into conventional and TMR diets treatments in a randomized complete block design. Conventional diet was based on forages and commercial diet. All animals were housed in individual metabolism crates and were fed ad libitum. Water was available at all times. Experimental period totally lasted for 38 days, consisting of 14 days of adaptation, 10 days of preliminary period and 14 days of sample collection period. Daily dry matter intake was significantly (p<0.05) higher in TMR treatments of the crossbred goats. Within breeds, crossbred rather than native-bred consumed more highly, and within the feeding type, TMR diets were more fed in comparison with conventional diet. Average daily gain ranked the highest in crossbred : TMR, followed by crossbred: conventional diet, native-bred: TMR, and native-bred: conventional diet (p<0.05). Dry matter digestibility was significantly (p<0.05) higher for TMR than for conventional diets, and it was higher in crossbred than in native-bred Korea black goats. Nitrogen retention was highest in TMR treatments of crossbreed, whereas it was lowest in conventional diet of native breed (p<0.05). Plasma glucose and urea nitrogen concentrations were significantly (p<0.05) higher in crossbred than in native-bred Korean black goats. Overall, the results indicated that feeding total mixed ration to crossbred rather than native-bred Korean black goats had more favourable influences on their performances, intakes, digestibility, nitrogen retention and blood metabolite characteristics. In conclusion, it is conceived that the results may contribute to economical benefit to farms producing Korean black goats together with establishment of an efficient feeding management system.
