processed into livestock feeds, starch,
chips, pellets, unfermented flour.

and malt drink.
Based on variety, soil and nutrient
availability yield varies between 18-31.8
Mt/yr.
Model prediction 35.5 – 48.4 Mt/yr.

Maybe!
If Greenseeker and pocket sensor are
calibrated for cassava production.
NDVI collections to show spatial variation
in field.
Active participation of local farmers to
embrace technology.
Cost of equipment.
Skilled personnel to demonstrate
technology.
Data management and processing.
Interpretation of data and application of
collated data.
Farmers understanding the concept of
technology and benefits.
Improved technology skills of farmers.
Availability of skilled personnel to answer
questions.

Effective participation of farmers.
Involving institute like IITA, because they
convey the message to farmers clearly.
Farmers trust the judgment and
technology from IITA.
