당근 수확작업에 대한 기계화 요구도가 높은 반면에 아직까지 수확작업의 기계화는 그다지 진전되지 못하고 있는 실정이다. 지금까지의 당근 등 근채류의 수확작업은 경운기용 또는 트랙터용 굴취기를 이용하여 작물을 지상위로 노출시키고 인력으로 수집하는 방법이 대부분이며 흙이나 돌 등 협잡물의 선별은 곤란하다. 또한 줄기절단 등 수확 후처리 작업이 기계화되지 못해 노동부담이 크다. (중략)

Vitamin and mineral composition of ethephon treated tomatoes were studied, and the results are summarized as follow: 1. Ascorbic acid, carotene (total and beta-carotene), thiamin and riboflavin contents in tomato fruits were not adversely affected by ethephon treatment 1 week before harvest, and these results were consistent for two consecutive years. Riboflavin content of tomatoes in 1979 was significantly higher than that in 1978, and this difference could be due to enviornmental factors. 2. Mineral content in tomato fruits were not significantly affected by ethephon treatment 1 week before harvest. Calcium and manganese contents in treated tomatoes significantly varied from year to year.

This study was conducted to analyze the effect of forest road network on accessibility and cost reduction for forest operations before and after forest road construction by investigating harvesting operations in 5 regional Forest Services (8 management planning districts). The results showed that the accessible operation area within 500 m from forest roads or public roads increased about 3.5 times after the forest road construction. The average cost reduction was 308,000 won/km/year. According to the results, forest road had a great effect on improvement of accessibility and reduction effect of forest operation cost. Therefore, the policy for expansion of forest road should be continued for preparing of effective harvesting system.

This study was conducted to know the change pattern of chemical components, especially proximate constituents, saponin and free sugars in roots of 4-year ginseng according to different harvesting time, and to find out the optimum harvesting time on the basis of chemical components in fourth year ginseng root. The crude protein content was 20.77% of the highest on the April (shootinzg stage),13.13% of the lowest on the June among all growing stages, and was constant at 17% after the August. But crude oil and fiber contents showed the highest value on the May (flowering stage). The content of total sugars which was the largest constituent among the chemical components in ginseng root was in the range of 60~7(1% during the all growing stages. It showed the highest value of 7l% on the June, but the lowest of 60% on the May. The total free sugar contents was the highest on the April (20.40%), but the lowest on the May (11.89%). The change pattern of sucrose contents (10.96-19.60%) was same as the total sugars contents (11.89-20.40%), on the other hand, the contents of glucose and maltose were not changed significantly during all harvesting times. The contents of crude saponins and total ginsenosides had the value of 7.60% and 4.09% on the May, respectively. That was statistically significant, but the other harvesting times were not. Therefore, on the basis of the only chemical characteristics in the four year-old ginseng root, we suggest that the harvesting on the May at flowering stage was most proper time.

The studies were conducted to escape for laber concentration during rice harvest and barley sowing through the scattering sowing before rice harvest(SS) compared to the drilling on high ridge(DS) of barley from 1990 to 1994. There were longer in plant height and more in tiller number under the SS than those under the DS of barley while cold-injured leaves of barley were inversely affected by two different sowing methods. The barley growth was more vigorous in the DS. There was similar at heading and maturing date. The grain yield of barley was lower in the SS by 20.6% which was resulted from the reduction of spike number per m$^2$ and number of grain per spike. There was not significant at growth and yield for sowing date before rice harvest. The variation of successive years on growth, yield and its components were higher in the SS than those in the DS.

Plan stability production investigating 1st harvesting degree for maximum leaf quantity enlargement, is as following it summarize result that test for 3 years since 2002 allowing 4 processing such as trunk lower column department harvesting, Foliar and rhizoma growth were tendency that give protective care 1 st harvesting height is short, but there were many the number of tillering crawl, Distribution of rhizome about diameter 5mm low 58%, large rhizome's ratio was high tendency harvesting height is short. Because foliar amount is much harvesting height is short in ground department, 15% rose in soil surface harvesting since 292kg provision per 5cm harvesting 10a, The time of refining the harvest of stems and leaves before drying has reduced when the height of the harvest is low, and the 5cm harvest has decreased 30% compared to the soil surface harvest.

Lower leaves of aromatic tobacco are also much lower in Quality than upper leaves. So feasibility test of no harvesting and curing of lower leaves was conducted under high planting density and high nitrogen conditions with conventional cultural system. Effect of harvesting time on yield and Quality were investigated under 2 nitrogen levels. Among harvesting methods of conventional harvest with priming under high planting density, no-harvest of first priming, removal of lower leaves which relevant to first prime stalk before maturity, no-harvest of first and second priming. no-harvesting or pruning of first prime stalk before maturity was best in yield, price and in crude income. The shortor the harvest period became, the lower the yield, price and contents of reducing sugar and nicotine became, but reverse in this trends with total nitrogen and protein nitrogen. So 6 or 8 days interval of harvest is most recommendable.

겨울동안 딸기재배의 작형은 딸기가 휴면기간이 매우 짧으면서 꽃눈분화가 조속히 이루어지는 품종을 선택하여 재배하는데 일반적으로 촉성, 반촉성 및 억제재배 등이 있으며 촉성재배는 비닐이나 섬피 등 보온을 실시하여 11월$\~$1월부터 2$\~$3월에 걸쳐서 수확을 목적으로 재배하는 작형이다. 반촉성재배는 촉성재배보다 보온을 늦게 시작하여 촉성재배의 수확말기인 3$\~$4월에 수확하여 출하하는 재배형이다. 억제재배에서와 같이 보통육묘를 실시해서 월동시킨 다음 봄에 생육이 시작하기 전인 2월 하순경에 모를 굴취하여 0$^{\circ}C$내외의 환경하에 장기간 저장하여 강제휴면을 시켰다가 8$\~$9월에 정식한 후 10$\~$11월경에 수확하는 작형이다. 이들 기본작형을 변형시켜 다시 세분화된 재배형으로 나눌 수도 있다. 본란에서는 현재 수익성이 높고 비교적 안전한 딸기 반촉성재배에 대하여 설명하고자 한다.

우리나라 고구마 재배면적은 2000년 16천㏊ 내외로 재배되고 있다. 국내 재배 주산지는 전남 해남, 여천, 경기 여주 순으로 주산지 지역특화작목으로 부상함에 따라 우리나라 전체 재배면적의 약 25%를 차지하고 있다. 이들 주산지에서 재배되는 고구마는 대부분 식용으로 이용되면, 가장 선호하는 고구마는 모양이 둥글고 크기는 100-200g 정도이며, 특히 최근 세 척 고구마의 유통이 증가함에 따라 껍질이 벗겨지지 않은 자색이나 홍색의 고구마를 선호하고 있어 수확 시 껍질이 벗겨지지 않게 수확할 수 있는 수확기가 절실히 요구되고 있다.

지금 세계는 인구증가로 인한 시량부족이라는 커다란 위기단계에 직면해있다. 현재 70억, 2050년까지 90억 이상의 사람들에게 충분한 식량공급과 식품품질을 확보하는 것은 국제사회가 처한 매우 중대한 도전이다. 급격히 증가하는 식량 수요를 만족시키기 위한 대부분의 해결책들은 필수적으로 농산물의 생산량 증가에 기반하고 있지만, 이제는 지구 환경을 보호하는 지속농업을 유지하면서 세계 식량생산량의 25%에 해당되는 수확 후 손실을 최소화하는 방향으로 접근하는 것에 초점을 맞추어야 할 것이다. 저온저장은 수확 후 손실을 줄이는데 핵심적인 역할을 해오고 있다. 현재 방사선, 건조, 염장, 고압가공, 통조림 등 많은 수확후 보존기술들이 부패하기 쉬운 음식에 적용되고 있기는 하나, 이들 어떤 기술도 저온저장 기술처럼 소비자가 요구하는 생산물 저장수명 연장과동시에 초기의 물리적, 화학적, 영양학적, 감촉 특성을 유지시켜 주지는 않는다. 따라서 저온저장기술의 이용 증대만이 식품의 양과 질 측면에서 보다나은 전 세계인의 영양공급을 확보할 수 있게 할 것이다.
