| Abstract: | The grain crop yield potential in Liaoning Province was analysed from its limiting factors and yield developing patterns. In Liaoning Province, the theoretical maximum yield potential for C4 crops such as maize and sorghum is 1434 kg/mu (lmu= 1/15 hectare), and the figure for C3 crop such as rice is 1070kg/mu Favourable goverment Policies in agriculture, science and technology,and goods and material input are the guarantee for further high-yield in crops. Strengthening the studies and utilization of high-yield farming system of techniques and improving the crop varieties are the technical paths to realize high crop yields. |
