Choose an accessible well-drained fertile soil.
The following varieties are recommended for their high yield and processing
quality: TMS 30572, NR 8082, NR8083, TMS 4(2) 1425, TMS 81/00110, TMS
92/0326. An additional 10 varieties are in the process of being released.
control and land preparation
A total herbicide – Round up (a glyphosate) should be applied at
the rate of 4–5 l/ha 10 days before land preparation.
effectiveness and optimum plant population, mechanization and planting
on ridges are recommended.
It is recommended that 5 (50 kg) bags of agricultural lime be applied
/ha during land preparation.
and planting material
1. Planting starts in April and can be extended to October.
2. The quantity recommended for 1 ha is 60 bundles of cassava stem.
3. Stem cuttings 25 cm long should be planted at a spacing of 1 m x 1
4. Maintain 100% planting rate by replacing dead or nonviable stems.
Where a total herbicide was not used before land preparation, it is recommended
that a selective pre-emergence herbicide be applied within three days
after planting. Five litres of Primextra is recommended /ha.
use, type and rate
The following fertilizers and their rate/ha are recommended
• NPK 15:15:15–12 (50 kg) bags
• NPK 20:10:10–9 (50 kg) bags
• NPK 12:12:17–15 (50 kg) bags
at 8 weeks after planting. Apply fertilizer in a ring, 6 cm wide and 10
cm from the plant or broadcast with care around the plant, making sure
the fertilizer does not touch the stem or leaves.
Yield of 25 t/ha and above can be obtained with good agronomic practices
To reduce cost of production and attain high yields, it is recommended
that land preparation be fully mechanized. A power tiller can be used
if the total land area under cultivation is not more than 250ha
