Decision factors for crop planning in paddy field management in early rice production area

As a case study of Miyazaki Prefecture

Abstract

This study aims to examine the factors influencing crop planning in paddy field management in early rice production areas. Miyazaki Prefecture is the earliest rice planting and harvesting area in Japan. In this study, the key factors considered are the timing of rice seed orders and the sales channels. The research methodology includes a questionnaire survey of and interviews with agricultural managers. The study found that rice seed orders are typically placed 2 years before sowing, and most agricultural managers determine sales channels in the autumn before harvesting. Therefore, crop planning decisions are made in the autumn prior to rice harvesting.
