Objectives : In this report, we were studied the current status and future about cultivation of medicinal plants in Japan. Methods : To analysis the management and production of medicinal crops in Japan, variation of importation and cultivation of four medicinal crops such as Angelica acutiloba Kitagawa, Cnidium officinale Makino, Paeonia lactiflora Pallas and Rehmannia glutinosa Liboschitz var. purpurea Makino within 22 years ($1981{\sim}2002$) were investigated. Also we analyzed the herbal drug market in Japan using literature. Results : In the results, cultivated area and amount of Angelica acutiloba Kitagawa and Paeonia lactiflora Pallas reduced more than 50% within 22 years ($1981{\sim}2002$). Production decrease of medicinal crops is alloting through contract production in China. The cultivation of Rehmannia glutinosa Liboschitz var. purpurea Makino is enforcing minimum procluction for seed security. Conclusion : We hope that this report stimulates research to investigate for the establishment of cultural practices in Korea.

본 연구는 기후변화에 따른 전국 맥종별(겉보리, 쌀보리 등) 생육 및 수확량, 보급종자 지역 등을 2019년과 2020년에 조사하여 재배한계지를 알아보고자 수행하였다. 2019년과 2020년에 쌀보리 및 겉보리 보급 종자는 우리나라 전역에서 보급되는 것으로 조사되었다. 맥류 재배시 품종과 보급종자 사용율은 맥종 및 지역별로 다르게 나타났다. 즉 2020년과 2021년에 지역별로 겉보리 보급종자는 0~100% 사용되었다. 2019년과 2020년 전국 쌀보리 평균 파종일은 10월 17일~11월 9일이었고, 겉보리 경우 10월 26일~11월 13일이었고, 맥주보리 10월 19일~11월 5일이었고, 쌀귀리는 10월 3일~11월 1일이었다. 즉 맥류 파종일은 연도 및 지역별 차이를 보였다. 즉 쌀보리의 경우 전남에서는 12월 12일까지도 파종한 농가가 있었다. 전국 맥종별 재배지역의 10a당 수량은 주산지와 재배한계지간에 차이를 보였다. 일부 재배한계지인 강원도 재배지역에서는 수확이 불가능하였다. 기후변화 시나리오에 의해 1월 최저온도에 의해 -10℃ 이하로 겉보리, -8℃ 이하로 쌀보리, -4℃이하로 맥주귀리와 쌀귀리 맥류 안전지대로 본 경우 한국의 최근 20년(2002-2021) 1월 최저평균 온도에 의하면 이들 온도지역에서 맥류가 재배가 가능한 것으로 나타났다. 또한 지역별로 맥류 보급 종자로 볼 때 우리나라 전역에 맥류 재배가 가능할 것으로 판단되나 실제로 맥류 생육과 수확량에 관한 실태 조사의 경우에서 일부 강원 지역 등에서는 작황불량으로 수확이 불가능한 지역도 있었다. 따라서 기후변화에 따른 맥종별 재배한계지 설정은 재배지의 생육 및 수량 등의 영향평가 등에 의해 재추정 되어야 할 것으로 판단된다.

An exploratory survey was performed to assess the present status of distribution and production of coconut palm (Cocos nucifera Linn.) in the rural landscape of Meghna floodplain of Bangladesh. A multistage simple random sampling technique was adopted to identify the study area and respondents. A total of 50 households were selected randomly for the study. Traditional knowledge on cultivation, management, and production of coconut palm was emphasized. Marketing of coconut palm products and income derived from coconut palm cultivation was taken into consideration. Perceptions of farmers, traders and professionals were described in due context of opportunities and constraints of coconut palm cultivation. Coconut palm cultivation was found to play an important role in household economy in rural Bangladesh sharing considerable contribution to the total income. About 10% of their total annual income was reported to come from coconut husbandry. Highest number of the coconut palms, 24%, was found to grow in the homestead compounds and in the pond banks. About one-third lands of the households were found to be covered by the coconut palms. Maximum, 19%, coconut palms were found in the 16-20 years age-class. Production of coconut was found highest at the age-class 11-15 years. The study found some important opportunities and constraints of coconut farming in rural Meghna floodplain area of Bangladesh. The results of this study would be useful for the rural development practitioners in Bangladesh.

감귤 중 우리나라에서 가장 많은 면적을 차지하는 온주밀감(Citrus unshiu Marc.)과 '부지화'[Shiranuhi, (Citrus unshiu ${\times}$ C. sinensis) ${\times}$ C. reticulata]를 대상으로 1981년부터 2010년까지를 기준년도로 하여 2090년까지 잠재적 재배지 변화를 예측하였다. 재배지 변화는 국가농림기상센터와 기상청에서 제공하는 기상자료와 RCP 8.5 기후변화시나리오를 바탕으로 제작된 30m 해상도를 가진 농업용전자기후도를 이용하였다. 온주밀감의 잠재적 재배적지는 기준년도에서는 대부분 제주 지역이 해당되었으며, 재배가능지는 제주 동부지역과 남해안 일부지역이 포함되었다. 2030년대에는 온주밀감 재배적지는 증가하였으며 재배가능지도 전남지역의 해안 지역을 중심으로 증가하였다. 2060년대부터는 재배적지는 제주 산간과 전남과 경남, 강원도 해안지역으로 점차 증가하고 재배가능지도 경북, 충남, 전북 지역까지 확대되었다. '부지화' 감귤인 경우 기준년도에서 재배적지는 제주 해안 지역 일부만 포함되었으며 재배가능지는 제주지역과 전남 남해안 일부 지역만 해당되었다. 2030년대 재배적지는 현재 온주밀감 재배지가 해당되었으며 재배가능지도 남해안 일부 지역까지 북상하였다. 2090년대에는 재배적지가 점점 증가하여 제주지역 전체와 전남, 경남, 강원도 해안지역이 재배적지가 되었으며 재배가능지도 점점 해안가를 중심으로 북상하였다. 이상의 결과를 종합하여 RCP 8.5 기후변화시나리오를 근거로 감귤의 재배적지변화를 예측해 본 결과 온주밀감재배적지는 감소하고 '부지화' 감귤의 재배적지는 증가하는 것으로 나타났으며, 21세기 말에는 강원도 지역까지 감귤이 재배될 것으로 예측되었다.

Optimum transplanting time for extremely early rice cultivation as an after-crop of fruit and vegetables under greenhouse conditions in the southern area was determined. Rice was transplanted on March 10, March 20, March 30, April 10 and April 20 far three years from 1998 to 2000. Meteorological computations for rice production were high for heading between early May and early July, but they were too low for heading between late July and early August. Especially the expected yield predicted with 35,000 spikelets, the average spikelets per $m^2$ for extremely early transplanting. Computation for heading between late July and early August was low by 106 kg/10a compared with that yield at heading during the same period in the field. As the transplanting date in extremely early rice cultivation was earlier) rice growth at early stages was more retarded by low temperature. Rice growth at heading stage recovered with high temperature, showing less difference for the transplanting date. Abnormal tillers occurred by 15.5∼22.2%. The contribution of 1,000 grain weight${\times}$ripened grain ratio to yield of the extremely early rice cultivation in the greenhouse was 50.6%, indicating 16% hi일or than the degree of panicle per $m^2$ on yield. The estimated optimum transplanting time on the basis of yield for the extremely early greenhouse rice cultivation ranged from March 19 to April 28, and the estimated critical transplanting date on the basis of accumulated effective temperature was March 12. Rice reduced the amount of NO$_3$-N by 97.1% and EC by 90.5% in greenhouse soil with continuous fruit/vegetables fer more than a 10-year period, and completely removed the root-knot nematodes.

In order to select the suitable soybean cultivars for paddly field cultivation, growth response and yields characters were investigated with 37 Korean domestic soybean cultivars, in Yeoncheon, Gyeonggi province. The results can be summarized as follows ; When the soybeans were cultivated in paddy field, significant differences were observed in growth responses at each growth stage and yields among the cultivars. Yields of six cultivars, such as Danbaekkong, Paldokong, Pungsannanulkong, Myeongjunamulkong, Saeolkong, and Namhaekong, were less than 200kg/10a, however, seven cultivars, such as Shinpaldalkong 2, Sohokong, Dormikong, keumkangkong, Bukangkong, Dajangkong, and Geomjeongkong 2, showed highest yields ranged from 301~385kg/10a. At V5 stage, highly positive correlation(r=091$^{{\ast}{\ast}}$) was observed between the top dry weight and leaf area while negative correlation was existed between T/R ratio and root dry weight. However, at R2 age, leaf area was correlated with both top and root dry weight while T/R ratio was correlated with leaf area and top dry weight. Thirty-seven soybean cultivars used in this experiments were classified into 3 different clusters based on 19 important agronomic characters, and genotypic properties of the cultivars were similar in each cluster. In results, high yields could be achieved by selected cultivation of suitable soybean cultivars such as Shinpaldalkong 2 which showed early maturation date and highly ripening ratio.
