2. Intertillage and weeding : In the north, sorghum needs to be intertillage and weeded three times during its growing period, especially in the early stage, when weeds must be removed completely. When using herbicides, spray them before germination.

3. Irrigation and drainage : Northern sorghum is drought-resistant, but it must be watered in time when it is particularly dry, otherwise it will have a great impact on the yield. In the rainy season, the accumulated water should be removed to avoid diseases and pests.
