Crop models have been used to predict vegetable crop yield, which would have a considerable economic impact on consumers as well as producers. A small number of models have been developed to estimate growth and yield of vegetables due to limited availability of growth observation data in high-quality. In this study, we aimed to analyze the protocols designed for collection of the observation data for major vegetable crops including cabbage, radish, garlic, onion and pepper. We also designed the protocols suitable for development and verification of a vegetable crop growth model. In particular, different measures were proposed to improve the existing protocol used by Statistics Korea (KOSTAT) and Rural Development Administration (RDA), which would enhance reliability of parameter estimation for the crop model. It would be advantageous to select sampling sites in areas where reliable weather observation data can be obtained because crop models quantify the response of crop growth to given weather conditions. It is recommended to choose multiple sampling sites where climate conditions would differ. It is crucial to collect time series data for comparison between observed and simulated crop growth and yield. A crop model can be developed to predict actual yield rather than attainable yield using data for crop damage caused by diseases and pests as well as weather anomalies. A bigdata platform where the observation data are to be shared would facilitate the development of crop models for vegetable crops. 생산자뿐만 아니라 소비자에게 상당한 경제적인 영향을 줄 수 있는 채소 작황 정보를 사전에 예측하기 위해 작물 모형들이 사용될 수 있다. 채소의 생육과 수확량을 추정하기 위한 모형들은 대다수 작물에 대해 개발되어 있지 못하며 이는 고품질의 생육 관측 자료들이 축적되지 않았기 때문이다. 본 연구에서는 배추, 무, 마늘, 양파 및 고추의 5대 채소들을 대상으로 작물 모형 개발과 검증을 위한 생육 자료를 수집할 때 사용되는 프로토콜을 분석하고 이를 개선하고자 하였다. 작물 모형의 모수추정을 위해 사용되는 관측 프로토콜은 통계청과 농촌진흥청 프로토콜들의 단점을 보완하는 방식으로 개선될 수 있다. 작물모형은 기상조건에 따른 작물의 생육 반응을 예측하기 위해 사용되기 때문에 신뢰도 높은 기상 관측 자료를 확보할 수 있는 지역에서 표본 필지를 선정하는 것이 유리할 것이다. 또한, 최소한의 표본 조사 필지에서 상세한 관측자료 수집하기 위해 관심 작물이 재배되고 있는 지역 중에서 기후 특성이 상이한 지점들을 대상으로 표본 조사 필지들을 선정하는 것이 권장된다. 작물 생육 모형의 개발 및 검증을 위해서는 시계열적으로 얻어지는 작물 생육 모의값과 비교하기 위해 일정 시간 간격별로 관측 자료를 수집하는 것이 필수적이며, 기존의 프로토콜에 제시되지 않았던 생육 초기의 관측값을 확보하는 방향으로 개선되어야 할 것이다. 병해충 조사항목들과 기상재해 양상과 관련한 항목들이 작물모형 개발을 위한 관측 프로토콜에 포함된다면, 작물모형과 병해충 모형을 개발하고 이들 모형들을 통합하는 방식으로 실제 수량과 가까운 작황예측이 가능할 것이다. 또한, 표본조사 필지에서 다수의 구역을 설정하고, 이로부터 샘플을 채취하는 것이 관측자료의 신뢰도를 높일 수 있다. 본 연구에서 제안된 프로토콜을 사용하여 얻어진 관측자료들이 자료 공유 플랫폼을 통해 제공된다면 채소 작물의 작황 예측을 위한 작물 모형 개발이 활성화될 것이다.

김은하,이성곤,박수윤,이상구,오선우,Kim, Eun-Ha,Lee, Seong-Kon,Park, Soo-Yun,Lee, Sang-Gu,Oh, Seon-Woo 한국식물생명공학회 2018 식물생명공학회지 Vol.45 No.4

국립농업과학원 생물안전성과는 생명공학기술로 개발되는 작물(GM작물)의 안전성 평가 중 '성분분석에 의한 비교평가'에 참고자료로 활용할 수 있도록 기존 상업화 작물성분의 분석 데이터를 제공하는 "작물성분 DB"를 구축하였다. "작물성분 DB"는 우리나라의 자연 환경에서 재배되는 주요 작물 품종들의 영양성분 함량정보를 제공함으로써 품종과 재배 지역, 연도에 따라 함량의 변화 정도를 확인할 수 있도록 데이터를 업그레이드 하고 있다. 현재 2곳 이상의 재배지역에서 2년 이상 재배한 벼와 고추 시료에 대한 주요 영양분과 항영양소, 2차 대사산물을 검증된 분석 방법을 사용하여 분석한 데이트를 제공하고 있다. 데이터는 평균값과 최저, 최대값을 제공함으로써 GM작물의 안전성 평가시 GM작물과 대응 비교작물 간에 나타나는 통계적 차이가 기존 상업작물의 생물학적 차이 또는 허용범위 내에 속하는지를 평가할 수 있도록 하였다. "작물성분 DB"는 사용자가 선택한 쿼리를 기반으로 쉽게 검색하고 활용하도록 하고 있다. 또한 유색미와 감자, 고구마, 콜리플라워와 같은 유색 작물의 기능성 성분 함량 정보를 제공하고 있어 일반 소비자들도 유용하게 정보를 활용할 수 있다. 본 논문은 상업작물 성분에 대한 중요한 정보를 제공하는 농진청 "작물성분 DB"의 구성과 사용법을 소개하였다. The Biosafety Division of the National Academy of Agricultural Science has developed a 'Crop Composition DB' that provides analytical data on commercialized crops. It can be used as a reference in the 'Comparative Evaluation by Compositional Analysis' for the safety assessment of genetically modified (GM) crops. This database provides the composition of crops cultivated in Korea, and thus upgrades the data to check the extent of changes in the compositional content depending on the cultivated area, varieties and year. The database is a compilation of data on the antioxidant, nutrient and secondary metabolite compositions of rice and capsicum grown in two or more cultivation areas for a period of more than two years. Data analysis was conducted under the guidelines of the Association of Official Analytical Chemists or methods previously reported on papers. The data was provided as average, minimum and maximum values to assess whether the statistical differences between the GM crops and comparative non-GM crops fall within the biological differences or tolerances of the existing commercial crops. The Crop Composition DB is an open-access source and is easy to access based on the query selected by the user. Moreover, functional ingredients of colored crops, such as potatoes, sweet potatoes and cauliflowers, were provided so that food information can be used and utilized by general consumers. This paper introduces the feature and usage of 'Crop Composition DB', which is a valuable tool for characterizing the composition of conventional crops.

Conditions of farm crop switching are affected by several important external factors such as agricultural products import opening, policy support, and climate change. Farming environment is always changing; barriers to imports are becoming lower and lower because of FTA and others, and climate change affects a boundary line of cultivation. Those situations give farmers motivation to change crops in order to cope with them. In addition, crop switching has been done in response to the local government measures about purchase of local agricultural products according to the local food and the expansion of organic agricultural products in school meal. Even though the favorable environment toward crop switching has been created, there are not many researches or outcomes regarding crop switching. Only few studies focus on the list of decision-making in crop switching, and locally suitable crop selection is not treated. In order to utilize crop switching as a farm management strategy, the proper frame should be studied and practical researches on application possibility also need. Therefore, study on crop switching is in a timely, proactive manner because farms catch the chance of expansion of school meal by changing crops. This paper applies HERO model used for venture foundation process to crop switching process. Success factors of HERO model are comprised of Habitate,Entrepreneurship, Resource, and Opportunity, and these phased application factors are applied to crop switching process. By doing so, each phase success factor of crop switching can be uncovered. Three farm organizations supplying organic agricultural products to schools are studied in Gyeonggi province. As a result, the stabilization stage cannot be achieved because of the habitate conditions and social conditions with low risk bearing of crop switching and current school meal systems are the main problems to block the diversification of risks. In order to succeed in crop switching, constructing the habitate in local districts or in systems of school meal is more effective than supporting each farm.

Improving remotely-sensed crop monitoring by NDVI-based crop phenology estimators for corn and soybeans in Iowa and Illinois, USA

Seo, Bumsuk,Lee, Jihye,Lee, Kyung-Do,Hong, Sukyoung,Kang, Sinkyu Elsevier 2019 Field crops research Vol.238 No.-

<P><B>Abstract</B></P> <P>Weather-related risks in crop production are not only crucial for farmers but also for market participants and policymakers since securing food supply is an important issue for society. Although crop growth condition and phenology represent essential information regarding such risks, extensive observations of these variables are virtually non-existent in many parts of the world. In this study, we developed an integrative approach to remotely monitor crop growth at a large scale. For corn and soybeans in Iowa and Illinois in the United States (2003–2015), we monitored crop growth and crop phenology with earth observation data and compared it against the United States Department of Agriculture National Agricultural Statistics Service (NASS) crop statistics. For crop phenology, we calculated three phenology metrics (i.e., start of season, end of season, and peak of season) at the pixel level from the MODIS 16-day Normalized Difference Vegetation Index (NDVI). For growth condition, we used two distinct approaches to acquire crop growth condition indicators: a process-based crop growth modeling and a satellite-NDVI-based method. Based on their pixel-wise historical distributions, we monitored relative growth strength and scaled-up that to the state-level. The estimates were compared with the crop progress and condition data of NASS. For the state-level phenology, the avg. root-mean-square-error (RMSE) of the estimates was 8.6 days for the all three metrics after bias correction. The absolute mean errors for the three metrics were smaller than 2.6 days after bias correction. For the condition, the state-level 10-day estimates showed moderate agreements with the observations (avg. RMSE = 10.02%). Notably, the condition estimates were sensitive to the severe degradation in 2003, 2012, and 2013 for both crops. In 2010, 2011 and 2013, unusually high errors occurred at the very beginning stage of growth (DOY 140–150), which attenuated over time. As the cumulative biomass and NDVI showed little change in comparison to the period mean biomass and NDVI for the spikes, this seems to be an error associated with variations in growth timing. Overall, the model using accumulated NDVI (S5) is preferable due to its performance and methodological simplicity. The proposed approach enables us to monitor crop growth for any given period and place where long-term statistics are available. It can be used to assist crop monitoring at large scales.</P>

This study was conducted to compare annual productivity of whole crop rice and winter crops in paddy field of southern region in Korean peninsular. Whole crop rice (WCR) varieties used in this experiment were Suwon 605, Yeongwoo, and Mogwoo bred at the National Institute of Crop Science (NICS), and Rye (Gogwoo), Italian ryegrass(IRG, Greenfarm) and Triticale (Choseong) were used as winter crops. Each crop was cultivated using the standard cultivation method and harvesting of whole rice was carried out about 30 days after heading date. The dry matter (DM) content was the lowest in Italian ryegrass (p<0.05), and the highest value was 29.4% in triticale. The dry matter yield of rye was the highest (p<0.05), and there was no significant difference between Italian ryegrass and triticale (p>0.05). There was no difference in forage quality among seeding time of each species, but there was a difference among the species (p<0.05). In particular, rye showed lower CP, IVDMD, TDN and RFV values than other species. The average dry matter production of whole crop rice was 18,484 kg/ha, but there was no significant difference among the cultivars (p>0.05). Crude protein (CP) content was significantly lower in Mogwoo than other and TDN and RFV values were the highest in Mogwoo. In the annual productivity evaluation, combination of rye-Suwon 605 showed the highest DM yield at 26,515kg/ha. Based on the above results, it was concluded that the combination of Suwon 605-rye (Gogwoo) was the most effective cropping system for annual forage production using whole crop rice and winter crop in the southern region of Korean peninsular.

To select rice (Oryza sativa L.) cultivars suitable for forage–rice double cropping system, the growth and grain quality of four early maturing rice cultivars (Joun, Jopyeong, Haedamssal, and Unkwang), and the chemical properties of soils were investigated under single- (fallow–rice) and forage–rice double-cropping systems in paddy fields in Miryang, southern Korea. The soil where two forage crops [Italian ryegrass (Lolium multiflorum Lam.) and oat (Avena sativa L.)] were cultivated during winter had a slightly lower pH; an increase in total nitrogen (T-N), K, Ca, and Na contents; and a slight decrease in organic matter and available P2O5 contents, compared with the soil fallowed during winter. This shows that the chemical properties of paddy soils can be improved by winter forage cropping. At the heading stage, the culm length, panicle length, panicle number, and leaf color of all cultivars, except for Haedamssal, were generally higher under double-cropping than under single-cropping. For Haedamssal, the culm length and leaf color did not differ between the cropping systems, but the panicle length was slightly shortened and its panicle number increased under double-cropping. After harvest, the yield of milled rice decreased for all cultivars except Haedamssal, but increased in Haedamssal under double-cropping. The head rice rate was slightly higher under double cropping, particularly in Jopyeong and Haedamssal, than under single-cropping. The protein content of milled rice under double cropping was higher and its amylose content was similar or slightly lower compared to those of rice under single cropping, resulting in decreased Toyo values for rice under double-cropping. The pasting temperature did not differ significantly between the cropping systems. However, Haedamssal had a low pasting temperature but a high Toyo value under double cropping, compared to the other three cultivars, suggesting that its palatability is relatively high. Furthermore, panicle number increased and milled rice yield did not decrease, even under double cropping. Therefore, Haedamssal seems to be the best cultivar for paddy-based double cropping with forage crops. 본 연구에서는 사료작물-벼 2모작 작부체계에 적합한 벼품종을 선발하고자, 사료작물 중 재배면적이 가장 많은 이탈리안라이그라스와 귀리를 연계한 2모작 작부체계에서 토양특성, 조생종 벼의 생육 특성과 미질의 변화를 조사하였다. 벼 앞그루로 겨울철에 휴경하였을 때보다 사료작물을재배하였을 때 논 토양 내 pH가 다소 낮아지고 T-N, K, Ca, Na 함량이 높았으며 유기물과 유효인산(Av. P2O5) 함량은 다소 감소하였다. 이는 겨울철 사료작물 재배로 인해논 토양의 화학적 특성이 개선될 수 있음을 보여준다. 출수기에 해담쌀을 제외한 3종의 조생종 벼에서는 간장, 수장, 수수, 엽색도가 대체로 벼 단작에 비해 사료작물-벼 재배답에서 높게 나타났다. 그러나 해담쌀은 간장과 엽색도가 차이가 없고, 수장이 다소 짧아졌지만 수수는 오히려 증가하는 양상을 보였다. 그리고, 수확기에 백미수량이 2모작 작부체계에서 다른 3종은 다소 감소하지만 해담쌀은 차이를보이지 않았다. 그리고, 완전미의 비율은 사료작물-벼 2모작 재배 시 다소 높았으며, 특히 조평과 해담쌀에서 높았다. 백미의 단백질 함량은 벼 단작에 비해 사료작물-벼 재배에서 높았고, 아밀로스 함량은 벼 단작과 같거나 그보다 다소낮았다. Toyo 식미치는 사료작물-벼 작부체계에서 대체로감소하였으며, 호화온도는 모든 품종에서 작부체계별로는통계적으로 유의미한 차이를 보이지 않았다. 그럼에도 불구하고, 해담쌀은 2모작 작부체계에서도 다른 품종에 비하여 호화온도가 낮으면서 Toyo 식미치값이 높아서, 식미도가장 양호한 것으로 나타났다. 더욱이 그 생장은 작부체계에 따라 차이가 없으나 수수는 오히려 2모작 작부체계에서증가하여 백미수량 감소가 없는 것으로 나타나, 해담쌀이사료작물과 연계한 논 기반 작부체계에 최적의 품종으로보인다.

The green manure crops are returned to soil when the plants are still green. The green manure crops play a role in reducing chemical fertilizers, improvement of soil fertility, reduction of soil erosion, weed control, and landscapes effect. Typical green manure crops are barley green manure, hairy vetch, chines milk vetch and clovers. We sowed 49 species of green manure crops in upland soil to increase the usage of green manure crops. We searched the effectiveness of green manure yield, C/N ratio, soil mulching, and landscape effect. The green manure crops that have 5 ton ha<SUP>-1</SUP> or more of green manure yield (fresh weight) were 6 gramineous crops, 4 leguminous crops, and 3 others. Green manures yield in a short growth period was higher in gramineous crops than leguminous crops. Among the green manure crops, 3 gramineous crops, 12 leguminous crops, and 3 others were under 25 in C/N ratio. Seven gramineous crops, 8 leguminous crops, and 5 others were over 50% of soil covering rate. Green manure crops that have beautiful flowers were in total 16 kinds, such as 4 gramineous crops, 6 leguminous crops, and 6 others. In result, based on green manure yield and C/N ratio, excellent species in the green manure crops were 4 species (triticale, 2 kinds of hairy vetch, and lupin). Green manure crops that were effective at soil mulching were 20 species, like hairy vetch, oats, sorghum, phacelia, buckwheat, etc. Buckwheat, crotalaria, mustard plant, phacelia, and etc. could be available for landscape crops.

ABSTRACT This study aimed to develop a cropping system to use limited crop-land with optimum efficiency, whileconsidering management from farmers. To establish the cropping system involving a two-year rotation of three crops, three typesof cropping system were evaluated in Suwon (Seogcheon series) and Anseong (Geumcheon series) in the middle plain area usingsix crops from 2018 to 2019: maize-perilla-onion, potato-sesame-garlic, and maize-sesame-onion. The crop productivity andincome of the cropping systems involving food-, oilseed-, and horticultural crops were analyzed, and the optimal cropping systemwas reviewed. The total yield of each crop was as follows: maize 1,281 kg, potato 4,837 kg, perilla 125 kg, sesame 120 kg, onion6,503 kg, and garlic 1,027 kg per 10a. However, in terms of gross profit, the potato was more than 3.8 times more profitable thancorn, sesame was 1.8 times more profitable than perilla, and garlic was more than 2.8 times more profitable than onions. As aresult, in terms of net income, the potato-sesame-garlic cropping system produced the highest income per unit area. Sesameseedlings were planted after the potato harvest, thereby solving the problem of competition between the first and last crops. Overall, this study confirmed that the potato-sesame-garlic cropping system, a two-year rotation of three crops, contributed to theimprovement of upland crop productivity and farmers’ income and was an overall effective cropping system. 적 요우리나라의 쌀 과잉 문제를 해소하면서 경지이용률과 식량자급률을 향상시키기 위한 논 이용 작부체계는 주로 1년2모작으로, 특히 남부지역에 비해 낮은 경지이용률을 보이는 중부지역의 기상적 특성을 고려한 새로운 형태의 작부모형 개발이 요구된다. 농가 수익성과 노동력 효율적 배분 등경영적 측면을 고려하면서 제한된 토지를 최대한 효율적으로 이용하기 위해 식량작물, 유지작물, 원예작물을 연계한 2년 3모작 작부체계를 도입하여 생산량과 소득을 분석하고최적 작부체계를 검토하였다. 수량성 측면에서 10a 당 옥수수가 감자보다 3배 이상이었고, 들깨가 참깨보다 5 kg 가량높았고, 양파가 마늘보다 6.3배 이상 높았다. 그러나, 조수익측면에서 감자가 옥수수보다 3.8배 이상 높았고, 참깨가 들깨보다 1.8배 높았으며, 마늘이 양파보다 2.8배 이상 높은 것으로 산출되었다. 결과적으로, 순소득 측면에서 ‘옥수수-들깨-양파’ 또는 ‘옥수수-참깨-양파’ 보다 ‘감자-참깨-마늘’을연계한 작부체계가 동일 면적에서 상대적으로 높은 소득을보이는 것을 확인하였다. 1모작 작물인 감자와 2모작 작물인참깨의 재배기간이 겹치는 문제는 감자 수확기 동안 참깨를육묘하고, 감자 수확 후 참깨 유묘를 이식하는 방법을 통해1모작 작물과 2모작 작물 간의 재배기간 겹침 문제를 해소할 수 있었다. 따라서, 본 시험에서 확인한 ‘감자-참깨-마늘’연계 2년 3모작 작부모형이 중부 평야지 논 이용 밭작물의생산성 향상과 소득 작물을 연계한 농가소득 향상에 합리적인 작부체계로써 기여할 수 있는 것으로 생각된다.

This work studied the growth and yield of green crops, changes of mineral composition in greenhouse soil and green crops, and infection with wintering green crops cultivation in greenhouse field. At 74 days after seeding of wintering green crops, dry matter was 710㎏/10a in rye, 530㎏/10a in barley, 230㎏/10a in hairy vetch, and 240㎏/10a in bean or weeds. Total nitrogen content in green crops was 4.5% in pea and hairy vetch, and 3~4% in barley and rye. P₂O₅, CaO, and MgO contents in all green crops were about 1.0%, and K₂O content was the highest level by 4~5% among macro elements. Total nitrogen fixing content in shoot green crops uptaken from soil was 22.1㎏/10a in rye, 20.6㎏/10a in barley, 10.6㎏/10a in hairy vetch, and 9.6㎏/10a in pea and giant chickweed. P₂O₅ fixing content in shoot green crops uptaken from soil was 8.4㎏/10a in rye, 6.3㎏/10a in barley, and 2.3 ㎏/10a in hairy vetch and pea. K₂O fixing content in shoot green crops uptaken from soil was 28㎏/10a in rye, 24.7㎏/10a in barley, and 11㎏/10a in hairy vetch and pea. CaO fixing content in shoot green crops uptaken from soil was 2~3㎏/ 10a in all green crops, and MgO fixing content was 1.7~2.6㎏/10a in all green crops. Pepper growth in no-tillage was not a significant difference at all green manure crops. The number of fruit and fruit weight were higher in control, pea, hairy vetch and harvest barley than rye and barley. Soil mineral compositions in wintering green crops increased at pH, organic matter, CEC compared with control. Soil chemical compositions were stable level at green crops cultivation according as decreases of EC, available phosphoric acid, Ca, and Mg contents. After no-tillage by green manure crops, pH in soils was higher in green manure crops than control. EC content in soils was lower in green manure crops than control, and was remarkably low level in barley harvest. Organic matter content in soils increased in hairy vetch and barley green manure but decreased by 35% in barley harvest. Total nitrogen and avaliable P₂O₄ content in soils remarkably increased but was not a significant difference at all green manure crops. Cation (K, Ca, and Mg) content in soils decreased by 15~20% in K, 2~11% in Ca, and 3~6% in Mg at rye, barley and pea compared with control.

Residual Macronutrient Concentration and Follower Maize (Zea mays) Crop Performance in Soilless Growth Medium Previously Cropped with Six Musa Genotypes

Emmanuel Ortese,Paul Kayode Baiyeri,Felix Detuhan Ugese 한국작물학회 2011 Journal of crop science and biotechnology Vol.14 No.4

The nutrient mining abilities of six Musa genotypes: ‘Agbagba’, ‘PITA 22’, ‘Nsukka Local’, ‘FHIA 17’, ‘Fougamou’, and ‘BITA 7’, grown in organic medium formulated by decomposing rice husks with poultry manure in volume proportions of 3:2, were determined at the Teaching and Research Farm of the Department of Crop Science, University of Nigeria, Nsukka, Nigeria. Results indicated significant variation in nutrient mining with respect to Musa genotype and duration of growth. The medium previously cropped with ‘Agbagba’ recorded highest residual mean values for P and Ca, while the medium cropped with ‘Fougamou’ had the highest residual concentration of Mg and S. Residual amount of K was highest in the medium where ‘PITA 22’ and ‘Nsukka Local’ were previously grown. Peak residual concentration of P and K occurred in the medium in which Musa plants were grown only for 4months, decreasing thereafter, in contrast to Ca, Mg, and S. Residual N tended to increase with longer growth duration of the Musa crops. Follower crop of maize grown in the medium previously cropped with Musa genotypes showed variable performance. While medium previously cropped with ‘PITA 22’ and ‘BITA 7’ favored growth attributes and leaf greenness of the follower maize plant,‘Fougamou’ favored maize fresh weight attributes. Ectomycorrhiza association was observed in medium previously cropped to ‘BITA 7’ and ‘PITA 22’. Generally, ‘Agbagba’ and ‘Fougamou’ seemed to be the most reticent nutrient miners while uptake of P and K appeared to be low 4 months after planting (MAP) in contrast to Ca, Mg, and S uptake. However, substrate previously cropped with ‘PITA 22’, ‘BITA 7’ and ‘Fougamou’ gave rise to superior growth and fresh weight attributes, respectively, of the maize, the follower crop. A prospect of utilizing the ectomycorrhiza association observed with some genotypes to upgrade Musa yields and those of associated or follower crops exist. Key words: follower crop, maize growth, Musa genotypes
