  • This experiment was carried out to compare chemical composition, TDN yield of corn-soybean intercropping and corn monocropping forage plants at different harvesting time and obtained the following results. 1. In both cropping systems, the content of chemical composition of forage were changed same pattern in growing stage. The content of crude protein in corn-soybean intercropping forage at yellow stage increased more than that of corn nonocropping forage, while the crude fat in corn monocropping forage plants increased than that of corn-soybean intercropping forage plants at mature stage. 2. The crude fiber, crude ash, ADF content of forage plants in both cropping system decreased same pattern in growing period, however, NFE content of forage increased with maturity. 3. TDN yield of corn-soybean intercropping and corn monocropping forage plants at yellow stage obtained similar results and TDN yield per 10a in intercropping and monocropping were 1006.lkg and 978.6kg, respectively. 4. Consequently, corn-soybean interaopping system could be increased crude protein yield without decreasing of dry matter yield in comparison with corn monocropping system for corn silage.

  • The soybean [Glycine max (L.) Merr.], an edible legume, has a high protein content in both its hay and grain, so it is often used as a supplement for other forages that have a deficient protein concentration. Therefore, this study investigated the forage quality and yield in the case of mixed planting of soybean and corn. The forage yield and quality were assessed for three cropping patterns: soybean mono planting, corn mono planting, and mixed planting of soybean and corn. For planting, this study used a forage corn cultivar, Kwangpyeongok, and three recombinant inbreed lines, W2, W4, and W11, selected from Glycine soja (PI483463)${\times}$G. max (Hutcheson). The mixed planting of soybean and corn produced a higher forage yield than the corn mono cropping. The crude protein and crude fat content were also increased with the mixed planting of soybean and corn when compared with the corn mono cropping. Some decrease of ADF and NDF, and increase for RFV in mixed planting of soybean and corn than corn mono cropping. Therefore, the results show that mixed planting of soybean and corn is an effective cropping system to improve the forage quality.

  • In attempt to avoid crop damage through wild bird's picking, this study was designed with aim to evaluate several pre-sowing soybean seed coatings for optimum yield in corn-soybean mixed forage. It was investigated under four cropping treatments, viz. 1) corn sole, 2) corn mixed with soybean without any coating, 3) corn with iron coated soybean and 4) corn with thiram coated soybean. Each treatment had three replicates and corn sole was control treatment. Pioneer (P1184) and crossbred ($PI483463{\times}Hutcheson$) seeds were used for corn and soybean, respectively. The trial was conducted under randomized block design from $5^{th}$ June to $23^{rd}$ September, 2015. Data were an alyzed through ANOVA technique using SAS9.1.3 software. Results depicted that survivability of soybean against wild birds damage was found better (p<0.05) in thiram coating which was higher than iron coating and control treatment but later on thiram coating had adverse effects on subsequent growth of soybean plants. Corn stalk height was decreased (p<0.05) in thiram coating, whereas corn ear height was reduced in iron coating treatment. Iron coating enhanced (p<0.05) height of soybean plant (p<0.05) better than that of thiram coating. Soybean seed coatings didn't influence dry matter yield and nutritive value in terms of total digestible nutrients yield in corn soybean mixed forage. Conclusively, although presowing thiram coating enhanced survivability of soybean plants against wild bird damage but had adverse effects on its subsequent growth. However, soybean seed coatings didn't influence yield and nutritive value of corn soybean intercropping forage.

  • Soybean (Glycine max (L.) Merill) is a very outstanding material crop with high protein and oil contents. We conducted this study to evaluate forage value and usability of soybean varieties as livestock forage. Three soybeans cultivars, OT93-26, Geomjeongsaeol, and Pungwon, were evaluated for forage use in this study, and Kwangpyeongok and Yeongwoo were used as check forage corn and rice, respectively. The whole soybean plants were harvested at the R5 (beginning seed development)- and R6 (full seed)-reproductive stages for analyzing forage usability and quality. Days to harvesting of the R5 stage-OT93-26 was the shortest among the tested crops while that of Yeongwoo was 122 days. The fresh and dry matter yields of all 3 soybeans were greater at R6 stage than at R5. Crude protein of the soybean cultivars harvested had a higher compared to the rice and corn regardless of the harvesting stage. Contents of crude fiber, neutral detergent fiber and acid detergent fiber of Yeongwoo had the lowest whereas Pungwon harvested at R5 were the highest. Among the soybeans, digestible dry matter, dry matter intake, and relative feed value of R6-harvested Geomjeongsaeol and Pungwon were high more compared to those at the R5-harvested, but in case of OT93-26 those at R6 stage were inversely measured rather than those at R5 stage. In conclusion, soybean can be used as s forage with high nutritive value for livestock. Moreover, Geomjeongsaeol can be applied to develop new forage soybean varieties with high nutritive value, and R6 stage is the optimum harvesting stage in yield and quality of the tested soybeans more than R5.

  • This experiment was conducted to evaluate feed value and usability of soybean varieties as livestock forage. In this study, three soybean cultivars, OT93-26, Geomjeongsaeol, and Pungwon, were harvested at R5 (beginning seed development)- and R6 (full seed)-reproductive stages for analyzing feed value of soybean. Days to R5 stage harvest of OT93-26 among the three soybean cultivars was 55 days and the shortest while Pungwon took 103 days to reach at R6 stage. The R6-harvested soybeans had higher dry matter (DM) yields and crude protein (CP) content than the R5-harvested. However, both DM and CP were the highest in the R6-harvested Geomjeongsaeol. Contents of neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Pungwon harvested at R5 were the highest whereas the R6-harvested Geomjeongsaeol had the lowest. Digestible dry matter (DDM), dry matter intake (DMI), and relative feed value (RFV) of the R6-harvested Geomjeongsaeol and Pungwon were higher than those of the R5-harvested, but in case of OT93-26, those at R6 stage were low rather than those at R5 stage. However, soybean could be used as alternative forage with high feed value for livestock. Taken together, Geomjeongsaeol could be used for developing new forage soybean varieties with high feed value, and R6 would be the optimum harvesting stage for yield and quality of forage soybean.

  • The aim of this study was to evaluate different herbicides in corn-soybean intercropping for optimum growth, yield and nutritive value of forage under Korean environment conditions. Herbicidal treatments were randomly applied over five plots, viz. (1) Control treatment: no herbicide; (2) Alachlor; (3) Simazine; (4) Pendimethalin and (5) Mixture of alachlor and simazine herbicides in RCBD have three replications. Results depicted that treated herbicides exhibited significant effect over control of weeds. Simazine herbicide alone or mixed with alachlor had adverse effects on soybean but enhanced (p<0.05) corn production in terms of survivability, dry matter and digestible nutrients yield. Corn-soybean coupling and total dry matter yield were greater (p<0.05) in pendimethalin. Simazine-alachlor mixture reduced (p<0.05) soybean height. Conclusively, simazine could not be suitable for corn soybean intercropping because of having an adverse effect on soybean component. Pendimethalin could maintain growth and yield of corn and soybean both components. Effect of alachlor was comparable to that of pendimethalin.

  • Corn is basal forage for livestock species in Republic of Korea but it lacks protein and needs nitrogenous fertilizer. This study was designed with main objective to achieve optimum growth, yield & nutritive value of forage for livestock through implementing corn-soybean intercropping strategy at 17 different places under Korean condition. Two treatments; corn as monocrop (control treatment) and corn-soybean intercrop were compared under Randomized Block Design from $28^{th}$ May to $8^{th}$ October, 2015. Each treatment had three replicates in each block, whereas seventeen different places were considered as blocks. Data were analyzed through SAS-9.1.3 software. Difference between two treatment means was tested through T-test. Findings depicted that intercropping pattern could not influence (P>0.05) corn plant & ear height, corn lodged stalk No. and corn stalks number. However, corn-soybean intercropping enhanced (P<0.05) forage productivity in terms of total fresh yield ($16.4{\pm}0.7^b$ vs. $19.9{\pm}0.7^atons\;ha^{-1}$), total dry matter yield ($5.38{\pm}0.25^b$ vs. $6.41{\pm}0.31^atons\;ha^{-1}$) and total digestible nutrients yield ($3.94{\pm}0.17^b$ vs. $4.59{\pm}0.21^atons\;ha^{-1}$). Dry matter percentage in corn stalks and corn ears was not different (P>0.05) between two treatments. It was concluded that corn-soybean intercropping strategy was promising technique in enhancing forage productivity though positive symbiotic relation between two crops.

  • One of the challenges to increase milk production in a large pasture-based herd with an automatic milking system (AMS) is to grow forages within a 1- km radius, as increases in walking distance increases milking interval and reduces yield. The main objective of this study was to explore sustainable forage option technologies that can supply high amount of grazeable forages for AMS herds using the Agricultural Production Systems Simulator (APSIM) model. Three different basic simulation scenarios (with irrigation) were carried out using forage crops (namely maize, soybean and sorghum) for the spring-summer period. Subsequent crops in the three scenarios were forage rape over-sown with ryegrass. Each individual simulation was run using actual climatic records for the period from 1900 to 2010. Simulated highest forage yields in maize, soybean and sorghum- (each followed by forage rape-ryegrass) based rotations were 28.2, 22.9, and 19.3 t dry matter/ha, respectively. The simulations suggested that the irrigation requirement could increase by up to 18%, 16%, and 17% respectively in those rotations in El-Nino years compared to neutral years. On the other hand, irrigation requirement could increase by up to 25%, 23%, and 32% in maize, soybean and sorghum based rotations in El-Nino years compared to La-Nina years. However, irrigation requirement could decrease by up to 8%, 7%, and 13% in maize, soybean and sorghum based rotations in La-Nina years compared to neutral years. The major implication of this study is that APSIM models have potentials in devising preferred forage options to maximise grazeable forage yield which may create the opportunity to grow more forage in small areas around the AMS which in turn will minimise walking distance and milking interval and thus increase milk production. Our analyses also suggest that simulation analysis may provide decision support during climatic uncertainty.

  • This study was carried out to select superior soybean cultivars for forage production for soybean forage production in Jeju. The results obtained are summarized as follows; Eighteen soybean cultivars were grown from May 11 to September 11 in 2002 in Jeju to select superior cultivars for forage production. Days to flowering was shortest(58 days) for Seokryangkong and Keunolkong, and longest(93 days) for Danpaheukdu. Days to flowering for other cultivars ranged from 65 to 69 days. Pureunkong and Namhaekong had greater heights(129.3 and 124.6 cm, respectively) while Keunolkong, Hwaeomkong and Seokryangkong had shorter heights. The number of branches per plant was gratest for Sobaekkong, Manrikong, Pungsankong, Kwangankong and Geumgangkong. The number of leaves per plant was geatest for Sobaekkong, Iksankong and Namhaekong. Rueunkong and Jangmikong had thicker stems. Fresh forage yield was greatest for Iksankong, Sobaekkong and Namhaekong(39.5, 39.3 md 38.0 MT/ha respectively). DM yield of forage was featest for Baekunkong, Hnrunkong and Danpaheukdu. Danwonkong, Dawonkong, Seokryanfong and Pungsankong had ueatest forage crude protein content. Duyukong and Kwangankong had featest forage crude fiber content. Jangmikong and Keunolkong had feater crude fat content, while Sobaekkong and Kwangankong had greater crude ash content. Namhaekong, Seokryangkong, Keunolkong and Jinpumkong had greater NFE contents ranging 40.0 to 43.5 and TDN was featest in Keunolkong, Danpaheukdu, Namhaekong and Seokryangkong had greater NFE contents ranging from 59.8 to 60.9%. The best cultivars in Jeju for forage soybean appear to be Namhaekong, Danpaheukdu md Baehukong on the basis of crude protein, TDN, and dry matter yields.

  • Soybean [Glycine max (L.) Merr.), mungbean [Vigna radiata (L.) Wilcz.], cowpea [V. unguiculata (L.) Walp.], adzuki bean [V. angularis (Willd.) Ohwi & Ohashi], maize [Zea mays L.], sorghum [Sorghum bicolor (L.) Moench], sorghum $\times$ sudangrass [So bicolor intraspecific hybrid], and Japanese millet [Echinochloa crusgalli var. frumentacea (Link) W.F. Wight] were grown at two planting dates (18 June and 15 July) at Cheju in 1997 to select the best forage legumes adapted to Cheju Island for grass-legume forage rotation. Averaged across planting dates and cultivars, dry matter (DM), crude protein (CP), and total digestible nutrient (TDN) yields were 5,646, 1,056, and 3,637 kg/ha for soybean, 4,458, 676, and 2,661 kg/ha for mungbean, 3,289, 553, and 2,055 kg/ha for cowpea, 3,931, 674, and 2,489 kg/ha for adzuki bean, 12,695, 969, and 7,642 kg/ha for maize, 17,071, 1,260, and 8,857 kg/ha for sorghum, 16,355, 1,163, and 8,543 kg/ha for sorghum $\times$ sudangrass hybrid, and 8,288, 929, and 4,091 kg/ha for Japanese millet. Soybean was higher in CP, ether extract (EE), and TON content but was lower in nitrogen free extract content compared with the three other legumes. The legumes had much higher CP (13.7 to 21.9%), EE (2.42 to 6.23%), and TDN (58.7 to 69.9%) content but lower in crude fiber (CF) content (17.3 to 25.3%) than did the grasses tested except maize which had relatively lower CF content but higher TDN content. These results suggest that soybean could be the best forage legume for grass-legume forage rotation in the Cheju region.
