  • In order to select the best varieties and cultivation methods for the production of domestic wheat for Hodugwaja(a walnut shaped confection), we carried out a 3-year experiment (2015~2017) to investigate the effect of different factors (crop variety, planting date, nitrogen fertilization) in a double cropping system (wheat then rice) on crop yields in the Cheonan area. Rice is the second crop in the system, and requires an accumulated temperature for 40 days of about $840{\sim}930^{\circ}C$ to ensure ripening. Transplanting dates for rice between June 29 and July 6 were suitable; transplanting on or after July 13 does not ensure ripening. The daily hours of sunshine ranged from 6.3 to 6.5 hours, which were slightly higher than the optimum of 6.0 to 6.1 hours. The higher the nitrogen fertilizer treatment, the higher culm length, and spike length of wheat. The yield of wheat per 10a tended to increase as the amount of nitrogen fertilizer increased. Wheat yields were highest for the Sooan variety, followed by Goso, followed by Keumgang. The number of days from transplanting to heading of rice were shortest for the Jopyeong variety followed by Unkwang, followed by Haedam. The yield of milled rice per 10a increased as the transplanting date was earlier and the transplanting date of June 9 showed the average yield of more than 500 kg in three varieties. From the results of the experiment, we recommend the Goso wheat variety and the Haedam rice variety for growing in a double cropping system under the climatic conditions of the Cheonan area.

  • The green manure crops such as rye, hairy vetch and scotch oat were applied to reduce the injury by continuous cropping system(CCS) of sesame(Sesamum indicum L.) cultivation, which manure crops was sowed in latter-September or mid-October and returned to soil in the next year of May. The growth and yields were increased as 33%(65.0kg/10a) in the rotational cropping system(RCS) compared to continuous cropping system of 48.9kg/10a. In the CCS of sesame, it was increased as $10{\sim}15%$ in the green manure crop cultivation, and rye cultivation was the most effective crop to reduce the injury of continuous cropping in the green manure crops. The RCS displayed lower disease outbreak and Fussarium oxysporum density in the soil compared with the CCS, and the green manure crop showed good effect in the CCS of sesame. In the RCS, the porosity was most high in the RCS and CCS of rye cultivation, while rye and hairy vetch was effective way to reduce the injury of continuous cropping. The outbreaks of wilt disease and phytophthora blight were increased as the CCS years, however displayed lowest outbreaks of disease and the yields showed highest in the rye cultivation.

  • This experiment was conducted to investigate the selection of regional double cropping system for production of organic forage in middle part of Korea. The species of forage crop used in this experiment were corn, $sorghum\;{\times}\;sudangrass$ hybrid and japanese millet for summer crops and rye and Italian ryegrass for winter crops. $Sorghum\;{\times}\;sudangrass$ hybrid showed higher DM (dry matter) and TDN (total digestible nutrient) yield than that of corn. Dry matter yield of corn decreased to 56% that of control because of weed. In winter crops, DM and TDN yield of rye is higher than that of Italian ryegrass. Rye was more adequate to produce organic forage in middle part of Korea. 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 $sorghum{\times}sudangrass$ hybrid (summer crop) and rye (winter crop) cropping system could be recommended as producing high yield of organic forage in middle part of Korea.

  • The provision of information on the profitability and efficiency during the transition from growing rice to substitute crops is an essential task for the proliferation and settlement of the production adjustment system. First, the profitability of the soybean + barley cropping system was analyzed. The average income of the farms with the soybean + barley cropping system surveyed was 868,000 Won, with an income proportion of 55.1%. With earned income that is approximately 1.7 times higher than that of growing only rice, it is determined to be more profitable. Then, the efficiency of the farms was analyzed through DEA analysis. The efficiencies of the farms were found to include the CCR model (0.927815) and the BCC model (0.97544). It was also found that there are 10 CCR and 14 BCC results with an efficiency value of 1. With an efficiency value of more than 0.9 on average, it can be deemed as efficient management in general. In addition, by presenting a proposal for the improvement of inefficient farms, the target value was provided in order for inefficient farms to become efficient farms.

  • Importance of climate change and its impact on agriculture and environment has increased with the rise Green House Gases (GHGs) concentration in the atmosphere. To slow down the speed of climate change many efforts have been applied in industrial sectors to reduce GHGs emission and to enhance carbon storage. In agricultural sector, many researches have been performed on GHGs emission reduction, but few on the role of carbon sink. In this study, we investigated carbon balance and soil carbon storage in agricultural field in the barley-red pepper and barley-soybean cropping system. With the system for automatic measuring of carbon dioxide, net ecosystem production(NEP) was estimated to be $6.3ton\;CO_2\;ha-1$ for N-P-K chemical fertilizer treatment plot and $10.6ton\;CO_2\;ha^{-1}$ for N-P-K chemical fertilizer with swine manure treatment plot in the barley-soybean rotation cropping. In the barley-red pepper rotation cropping, it was $12.0ton\;CO_2\;ha^{-1}$ for N-P-K chemical fertilizer treatment plot and $13.2ton\;CO_2\;ha^{-1}$ for N-P-K chemical fertilizer with swine manure treatment plot. Soil carbon storage rate was estimated to be $0.7ton\;C\;ha^{-1}$ for the barley-soybean cropping system and $0.5ton\;C\;ha^{-1}$ for barley-pepper cropping system. In appeared that agricultural lands may contribute to the greenhouse effect as a potential carbon sink preserving carbon into soil.

  • The effects of paddy-upland rotation and cropping system on the mineralization of soil organic nitrigen, on the change of organic matter and available phosphorus content in the soil, and on the rice yield and nutrients absorption were studied in Seokcheon fine-sandy loam soil. 1. In the incubation test mineralzed soil nitrogen and the nitrogen extracted by pH 7 phosphate buffer solutions were higher in the soils from every and two year rotation systems than continuous rice cultivation. In terms of cropping system potato-chiness cabbage-rice increased them more than soybean-rice system. 2. The change of soil organic matter and available phosphorus contents were not much in continuous rice cultivation, while in rotation system they decreased as the paddy-upland rotation frequency decreased. In terms of cropping system they decresed more in potato-Chinese cabbage-rice system compared with soybean-rice systems. 3. The rice yield was higher in the paddy-upland rotation system than that of continuous rice cultivation. However, the effects were decreased gradually every year, as shown by 26~20, 17~5, and 5~4% yield increase for first, second, and third year, respectively, in potato-Chinese cabbage-rice and soybean-rice system compared with continuous rice cultivation. 4. All the absorbed nutrient contents increased in every and two year rotation system compared with continuous rice cultivation. In terms of cropping system potato-Chiness cabbage-rice system increased them more compared with soybean-rice system.

  • A new demand for vegetable peanut (Arachis hypogaea L.) in Korea has increased farmers interest in growing vegetable peanut. Compared to grain peanut production, vegetable peanut production enables the growth period to be shortened by 20 or 30 days and farmers to adopt various cropping systems and to return crop residues in the soil. With the purpose of establishing desirable cropping systems for sustainable vegetable peanut production, three field experiments were conducted from 2000 to 2001 at Milyang, the southeastern part of Korea. Main focuses were given into the effect of cropping systems for vegetable peanut production on each crop's yield and soil sustainability. The cropping systems investigated were single vegetable peanut, peanut-radish-green barley, peanut-barley, and peanut-garlic cropping system, with or without crop residue incorporation in the soil. Among the cropping systems investigated for sustainable vegetable peanut production, peanut-only and peanut-radish-green barley cropping systems showed vulnerable to diseases and lodging while peanut-barley and peanut-garlic cropping systems showed higher stability in response to diseases and lodging, consequently leading to higher yield potential of vegetable peanut production. In the peanut-barley cropping system, both barley and peanut residues returned to the soil played an important role in soil improvement as well as in significantly increased grain yield of peanut and barley. A particular notice was taken to the pronounced increase in Trichoderma population and the amount of nitrogen mineralization induced by the returned barley residue. Soil structure, compactness, pH, and fertility were positively influenced by the returned crop residues, which apparently increased sustainability in vegetable peanut production systems.

  • This study was evaluated to compare annual productivity and feed value of Italian ryegrass and summer forage crops at paddy field in middle region of Korea. Italian ryegrass (Kowinearly) was used as winter forage crop, and forage rice (Youngwoo) and barnyard millet (Jeju) were used as summer forage crops. Each crop was cultivated using the standard forage cultivation method. The plant height, dry matter yield, crude protein content, and total digestible nutrient content of Italian ryegrass were 90.6 cm, 7,681 kg/ha, 9.2%, and 63.8%, respectively, and it was no significant difference by summer forage crops (p>0.05). The plant height of summer forage crops was the higher in barnyard millet than in forage rice (p<0.05). The dry matter, crude protein, and total digestible nutrient yields of summer forage crops were the higher in forage rice than in barnyard millet (p<0.05). Also, the feed value of summer forage crops was higher in forage rice than in barnyard millet. In conclusion, the combination of Italian ryegrass-forage rice was the most effective cropping system for annual forage production with high-yield and high-feed value, and it was considered the combination of Italian ryegrass-barnyard millet was good cropping system for annual forage production through reducing labor and cultivating stable at paddy field in middle region of Korea.
