Abstract

In the new changing scenario, the goal of agriculture is shifting from traditional to sustainable and environment-friendly agriculture. Therefore, in this experiment, we analyzed economic efficiency of two methods of rice cultivation i.e. new cultural method and conventional method, at farmers' fields. In the new cultural method, cost of materials and machines (rice-transplanting and sowing machine) was found 245% higher than the conventional method. Depreciation of cost and working hours were also higher in the new cultural method by 1.9 and 1.1 time, respectively. However, cost of seeds and seedbed soil were 44.0% and 49.2% lower and total material cost was 4.4% lower than the conventional method. In the new cultural method, overall working cost of nursery raising and transplanting per 10a was 229.8% higher than the conventional method. However, in spite of high input cost, yield of rice in new cultural method was higher by 6.7% than the conventional method. Our results showed that new cultural method was better than the conventional method except the input cost. If government provide 80% subsidy for machine cost then its input cost will be reduced by 45.4% than the conventional method.

친환경 식품이 소비자의 마음을 사로잡으면서 농업의 목표가 생산성 유지 및 향상과 환경의 질을 보존하는 새로운 패러다임으로 변화하고 있다. 따라서 환경친화적 농업(environmentally sound agriculture)이 강조되면서 친환경쌀 생산단지에서 공동으로 이용하고 있는 포트육묘 재배가 농가관행 산파육묘 재배에 비해 얼마나 효율적인지 경제성을 분석한 결과는 다음과 같다. 1. 포트육묘 이앙은 관행이앙 방법에 비해 이앙모판, 파종 및 이앙기 등의 가격이 245% 높았다. 따라서 감가상각비 역시 관행농법에 비해 포트육묘 이앙에서 1.9배 높았다. 2. 10a 당 투입된 노동시간, 노동력 및 비용은 포트육묘 이앙재배에서 각각 13%, 4% 높았다. 그러나 이앙 및 재배에 투입되는 농자재는 종자 및 상토비를 각각 44.0%와 49.2% 절감할 수 있기 때문에 관행농법 대비 4.4% 낮았다. 3. 또한, 포트육묘 이앙재배는 관행 산파육묘 이앙재배에 비해 수량증수에 의한 조수입의 증가(6.7%)와 이앙 후 초기 활착이 빠르고, 성묘이앙으로 초기생육이 양호하여 잡초방제에 유리한 점은 친환경 벼 재배에 적합한 요인으로 작용하였다. 4. 10a 당 육묘와 이앙단계에서의 경영비는 포트육묘 이앙재배에서 229.8% 높았으나 정부에서 80% 기기보조가 된 경우 관행 산파육묘 이앙재배 대비 경영비가 45.4% 절감되었다.
