Yearly Variation of Growth and Yield of Sorghum (Sorghum bicolor L.) under Different Paddy-Upland Rotation.

It has been reported that sorghum is rich in minerals, and vitamins, which are insufficient in rice, to prevent chronic diseases and prevent aging. Recently, as people are more concerned about quality of life, and interest in well-being foods has been increased, The consumption of sorghum has also increased (Park, 2012).Therefore, this study was conducted for three main purposes. The first was to investigate the growth and yield of sorghum in the organic paddy-upland rotation system, the second was to investigate yearly variation of growth and yield of sorghum and the third was to select the suitable varieties for paddy-upland rotation.
