Selection of Promising Varieties for the 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 for single or two seasons. Farmers determine various factors such as crops, varieties, and cultural methods to earn benefic gains under cropping system. 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 crop varieties under potato-sesame-garlic multiple cropping system in the central northern area of Korea.
