Development and Release of CSIR-Banse rice; a climate smart rice variety

2021-12-05

Problem that technology is supposed to solve :

Erratic rainfall pattern resulting from climate change limits productivity of rice fields because about 80% of rice fields in Northern Ghana are rainfed. Terminal drought is considered a major yield limiting factor in the region. CSIR-Banse rice; an early maturing variety (80-85 days), with adequate disease resistance and acceptable grain quality will help farmers escape the frequent terminal drought resulting from climate variability and late planting. C93 could also serve as a flood recession variety to help make use of residual moisture along the Volta river banks after flooding.

Technical characteristics of the technology :

  • Yield potential: 4.7-5 t/ha
  • Maturity days: 80-85 days
  • Tolerance to blast:  tolerant
  • Tolerance to BLB: tolerant
  • Grain quality:  Good

Economic characteristics of the technology

- Acquisition cost :

Cost of seed depending on the Ministry of Agriculture


- Economic profitability :

CSIR-Banse rice has a benefit cost ratio (BCR) of 1.25. A BCR value of 1.25 indicates that if a farmer invests GH¢ 1 in the C93 rice variety, the returns on the investment will be 0.25 after covering the cost of production.


- Comparative advantage :

CSIR-Banse rice is an early maturing variety which uses its early maturity to help farmer cope with terminal drought. It is able to yield 5 t/ha within 80-85 days.


Limits of the technology :

There is yield a yield penalty for the early maturing trait. CSIR-Banse rice could yield a maximum of 5 t/ha. It does not do well when nursed and transplant as pertain to irrigation ecologies.
