  • BACKGROUND: A region can be divided into agroclimatic zones based on homogeneity in weather variables that have greatest influence on crop growth and yield. The agro-climatic zone has been used to identify yield variability and limiting factors for crop growth. This study was conducted to classify agro-climatic zones in the state of Mato Grosso in Brazil for predicting crop productivity and assessing crop suitability etc. METHODS AND RESULTS: For agro-climatic zonation, monthly mean temperature, precipitation, and solar radiation data from Global Modeling and Assimilation Office (GMAO) of National Aeronautics and Space Administration (NASA, USA) between 1980 and 2010 were collected. Altitude and vegetation fraction of Brazil from Weather Research and Forecasting (WRF) were also used to classify them. The criteria of agro-climatic classification were temperature in the hottest month ($30^{\circ}C$), annual precipitation (600 mm and 1000 mm), and altitude (200 m and 500 m). The state of Mato Gross in Brazil was divided into 9 agro-climatic zones according to these criteria by using matrix classification method. CONCLUSION: The results could be useful as information for estimating agro-meteorological characteristics and predicting crop development and crop yield in the state of Mato Grosso in Brazil.

  • 우리나라 농업은 농지의 감소, 생산비 증가로 인한 수익성 악화, 외국농산물의 수입개방 등과 같은 대내외적인 농업환경 변화에 적응하기 위해 많은 변화를 모색하고 있다. 다시말해 우리나라 농업은 농축임산물의 생산부문 뿐만 아니라 생산물의 가공, 유통, 서비스에 이르는 모든 농업 관련산업에 신기술과 첨단과학을 점목시킴으로서 농업은 노동집약적인 일차산업이라는 인식을 불식시키고 근대적인 기술산업으로서의 활로를 모색하고 있다고 할 수 있다.(중략)
