Weeding and thinning

Weeding and thinning

• Weeds lower yields in sorghum so they should be controlled within the first 6 to 8 weeks after planting.
• Weeds vigorously compete with sorghum for nutrients and water during this period.
• Sorghum is normally weeded once in many parts of Uganda but it is recommended to weed at least twice.
• The first weeding should be done 2-3 weeks after germination while the second weeding should be done 6 weeks after germination depending on weed intensity.
• Weeding is done using hand hoe but animal traction is also effective.
• During weeding thinning and gap filling should also be done to a desirable plant population.
• This should be done immediately after or during the first weeding.
• Thin to 1 or 2 plants per hill for grain and seed production respectively.
• This should be carried out when there is adequate moisture in the soil to avoid stress.
• Gap filling should be carried out where necessary by transplanting within 2 weeks after emergence.
