Issues• The climate change reality (harsher, hotter, dryer

climates, associated pests and diseases)• Search for crops that can survive and cope in these

conditions• Cassava – the most resilient available (CIAT and

CGIAR’s, 2012)• Grossly under-rated and under-developed crop • Need to increase/promote production and

consumption of cassava• Different types of cassava available to suit a range of

consumer requirements Ministry of Industry, Commerce, Agriculture, & Fisheries, Research Division; Bodles Research Station , Old Harbour P.O., St. Catherine.

Methodology• Over several years collected and conserved 20 accessions of cassava - both

local and imported: Maintained duplicate/redundant collections at different locations

• Periodically characterize and evaluate the different cassava cultivars: Three months, Six and Nine months characterisation Leaf Retention and Prominence of foliar leaf scars

• Post harvest characteristics: - DM, starch, HCN Dry Matter Adapted from ASTM D2974(1995) Anthone Method of Extraction for Starch Colorimetric method for free and Potential Cyanide

Lessons learnt

• There is variability in agronomic traits between the cultivars

• All the cultivars in the Bodles Research Station collection are sweet and not bitter

• The collection contains high starch cultivars that are suitable for many industrial applications

• Cassava has been underutilized and there is great potential for research


Recommendations

• Greater use of cassava in Jamaicans diet, and as feed stock for animals substituting corn and sorghum

• Increased utilization of marginal lands with aim of bioremediation

• Exploit cultivars that can be grown both as ornamentals and food crops in landscaped environments (Edible Garden)


The Way Forward

• More educational program for children about the benefits of eating cassava

• More research- scientific and marketing research• Looking to use Cassava as a substitute crop for

Wheat, Barley, Corn and Sorghum because of lower cost of production and high yield

• Creating a demand in the diaspora and local market for cassava products which will increase farmers income.


THE END

• THANK YOU
