- Note all the NERICA varieties are early maturing

Economic characteristics of the technology

- Acquisition cost :

The cost of acquisition is approximately $25000 – 35000.

- Economic profitability :

- Increase farmers yields and productivity

- Increase farmers livelihood.

- Access to quality and improved seeds

- Comparative advantage :

The improved varieties generated are superior to the later varieties in term of high yielding, quality, resistance to biotic and abiotic stresses.

Limits of the technology :

- lack of adequate funds to disseminate technologies generated to end users.

- Lack of funds to multiply improved technologies generated.

- Lacks the necessary logistics required in the technology generation.
