A COMPREHENSIVE & PRACTICAL GUIDE ON HOW TO START CASSAVA FARMING & PROCESSING BUSINESS By : Micheal B . O .
POST-PLANTING WEED CONTROL Where a total herbicide was not used before land preparation for cassava plantation , it is recommended that a selective pre-emergence herbicide be applied within three days after planting . Five liters of Primextra is recommended / ha .
FERTILIZER 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
Apply fertilizer at 8 weeks after planting your cassava . Apply fertilizer in a ring , 6 cm wide and 10 cm from the plant or broadcast with care around the cassava plant , making sure the fertilizer does not touch the cassava stem or leaves .
YIELD Cassava Yield of 25 t / ha and above can be obtained with good agronomic practices and management . Therefore , every step must be taken seriously in the process of planting your cassava .
SOIL PREPARATION FOR CASSAVA FARMING
When cassava is grown as the first crop in forest land , no further preparation is required other than the clearing of the forest growth . When cassava is grown after other crops , it can often be planted without further preparation of the soil ( e . g . once the preceding crop has been harvested or the soil has been ploughed two or three times until it is free from grass and other plants ). Clearing of forest land is done to let in more sunlight to the ground and to remove weeds and undergrowth which might otherwise compete with economic plants . The practice is to clear the forest soil completely . All the roots and other obstructions beneath the soil must also be removed by slashing and burning of the forest cover . After this has been done , the land must be deeply ploughed . Burning is important as it also destroys soil parasites , and the layer of ashes increases the quantity of potassium salts available to the growing plants . However , it could lead to soil deterioration due to the leaching out of nutrients .
