During which month should sorghum be planted?

1. April

2. August

3. Early March

4. February

The correct answer is: April

Sorghum is typically planted in April because this timing aligns with optimal soil temperature and moisture conditions necessary for germination and establishment. In many regions, planting in April ensures that the soil has warmed sufficiently, fostering faster sprout and root development. Additionally, planting in late spring allows the crop to avoid excessive heat and drought conditions that are more prevalent in mid to late summer, thereby enhancing yield potential. Other months like February and early March are often too cool for optimal sowing, risking poor germination rates due to lower soil temperatures. August would also be inappropriate as it is too late in the growing season for sorghum, which needs several months to mature before the first frost in the fall. Thus, April is the most suitable month for planting sorghum.
