Development of Multiple Upland Crops Cropping System of Paddy Field in the Middle Area of Korean Peninsula

The first and most important advantage of cropping system is to increase output per area as multiple cropping involves cultivating two or more crops in the same field during one season. The techniques of cropping systems allow farmers to achieve better results by making practical use of resources such as soil, water, fertilizers etc. Various types of crops can be cultivated in mixed cropping practice, such as food crops, vegetables, silage crops. This helps farmers become self-sufficient in food production while also providing them the option to sell additional products for making money. This experiment was conducted to find out optimum multiple cropping system related to economic crops in the central northern area of Korea.
