  • This study was performed to determine the relative quality of mungbeans harvested in bulk after applying a labor-saving cultivation (LSC) method, compared to mungbeans harvested three different times under the conventional cultivation condition. There was no significant difference in starch, crude protein, and vitexin or isovitexin content of seed according to the cropping system or harvest time. The mungbeans grown under the LSC method had the highest crude fat content, followed by mungbeans from the third-, the second- and the first-harvest mungbeans under the conventional cultivation. No significant difference was found in the composite ratio of saturated fatty acids to unsaturated fatty acids according to cropping system or harvest time. The second-harvest mungbeans grown under the conventional cultivation condition had 17 different types of fatty acids, while the third-harvest mungbeans grown under the conventional cultivation and those grown under the LSC condition had the fewest types of fatty acids with 12. Of the major saturated fatty acids, palmitic acid and arachidonic acid had the highest composite ratio in the first conventional cultivation followed by the second, the third and the LSC. However, stearic acid showed the opposite tendency. Of the major unsaturated fatty acids, linoleic acid had the highest composite ratio in the first conventional cultivation, followed by the second and third conventional cultivation and the LSC. Amylogram characteristics of the mungbeans were significantly different according to cropping system and harvest times. The mungbeans harvested after the first conventional cultivation had significantly higher pasting temperature, peak viscosity, holding strength viscosity, final viscosity and breakdown, while mungbeans harvested after the third conventional cultivation had significantly higher setback viscosity. In contrast, the mungbeans harvested under the LSC methods had a significantly lower amylogram value. When harvest rate, color values and amino acid content of sprout were measured, mungbeans grown under the LSC conditions had a low harvest rate of sprout, but had Hunter's color values and amino acid content of sprout similar to those of mungbeans grown under the conventional cultivation condition.

  • We carried out this study to confirm the possibility of C. wilfordii cultivation using crop as a substitute for stake or net, and tested sit support crops, i.e., soybean, peanut, Perilla frutescens var. acuta Kudo, Job's tears, sorghum, and corn compared with net support. Effects of support crops on growth and root yield of C. wilfordii were as follows. Attracting efficiency of vine showed 94∼100% among crops. The number of branches per plant was 1 or 2 more in p. frutescens var. acuta Kudo, Job's tears, and sorghum support than in net support. Fresh root yield per 10a was 919kg in net support, while it was 717kg in P. frutescens var. acute Kudo, 656kg in Job' tears, and 652kg in sorghum support. However, the problem of decreased yield in these support crops could be overcome by cost saving of staking installation and by harvesting support crops. Therefore, C. wilfordii cultivation using P. frutescens var. acute Kudo, Job's tears, and sorghum as support crops showed most effective in labor and cost saving.

  • As the low labor-productivity is being floated up to be the most limiting factor in barley cropping, the endeavor of many researchers concerned have been concentrated on recovering from that. For this reason, in this experiment 8 kinds of sowing methods were employed to survey the yield productivity and the labor-requirement of each methods. And with promising the possibility of consistent mechanization, both prediction of the assurable requirement of labor investment and calculation of the labor productivity in each method were estimated so that the possibility of labor-saving in barley cultivation investigated. Also sowing methods for labor-saving cultivation were presented according to the labor-structure of farm as divided with the phases.

  • 우리나라와 같이 좁은 국토에 많은 인구가 먹고 살아야하는 실정에서 농약의 사용없이는 안전다수확은 도저히 기대할 수 없으며 또한 요즈음 같이 일손구하기 어려운 때에 농약의 사용없는 생력재배는 거의 불가능한 일이다. 따라서 농약사용이 필수불가결 한 것이라면 적절한 사용대책과 사용한 결과에 스스로 책임지는 자세가 필요하다.

  • 최근 과수산업은 소비자의 기호에 맞게 보다 품질이 좋은 품종의 재배가 증가하고 있기 때문에 정지전정(整枝剪定), 시비, 약제방제 등 재배관리법도 그 품종에 맞도록 바뀌고 있다. 또 산업화에 따라 농촌인구의 감소, 겸업농가의 증가등 사회요인의 영향도 있어 재배관리 작업의 생력화가 강조되고 있다. 이와 같은 재배환경의 변천에 따라 배나무의 병해 발생은 늘어날 것으로 전망된다.

  • Hydroponics, Nutriculture, Soilless culture 라고 불리워지는 양액재배는 결코 새로운 기술은 아니지만 최근 집약적 생산을 위한 공장적 재배 등을 통해서 다시 주목을 받고 있다. 과거에는 재배관리의 어려움 때문에 전문가 이외에는 재배가 곤란했지만, 최근 재배관리의 자동화경향 때문에 비전문가에 의한 관리도 가능하게 되고 있다. 양액재배는 토양재배에 비하여 여러가지 장점을 가지고 있다. 양액관리를 위한 장치의 개선과 적용작물의 선택, 생력관리기술이 확정되었고, 연작장애 대책, 안정적 계획생산, 무공해식품의 평가가 높기 때문에 양액재배 면적은 서서히 증가하는 추세라 할 수 있겠다.
