When is the right time to sow sorghum?

Sorghum planting time

Sorghum is an herbaceous plant of the Poaceae family. It can generally be sown in spring and autumn. Spring is suitable for sowing in March and April of the lunar calendar. The time should not be too early to prevent the temperature from being too low and it will easily wither and die when encountering cold currents. Autumn can be planted in May and June of the lunar calendar. The time should not be too late, otherwise low temperatures in the middle and late stages of growth will affect the ripening of the fruit.

Sorghum sowing method

1. Sorghum is suitable for planting on loose and fertile land. Before planting, the soil needs to be loosened and base fertilizer needs to be applied. Before sowing, seeds with full grains need to be selected and planted at a certain density. Field management requires thinning, inter-row cultivation and weeding, watering and fertilizing. Finally, attention should be paid to disease and pest control.

2. Specific method: Sorghum seeds can be winnowed or screened, and empty and diseased grains can be removed, leaving only large and full seeds. They should be exposed to the sun for 2-3 days, planted at a certain distance, and covered with a thin layer of soil. Thinning can be done when 3-4 leaves grow, and transplanting can be done when 5-6 leaves grow. Generally, inter-cultivation should be done 2-3 times during the seedling stage.

Sorghum is ripe for harvest

The time of sowing and harvesting of sorghum is different. Its growth cycle is about 100 days. If sown in spring, it will mature and be harvested in mid-August of the Gregorian calendar. Its yield per mu is related to the planting technology and the planting site. The yield per mu is generally 700-900 jin.
