2.4 session by gokhale dg cassava ifad 2010

  1. 1. Objectives of the presentation • Examine possibility of using cassava and tropical sugarbeet (TSB) as rotational crops so as to optimise cultivation as well as processing costs • Whereas cassava is commercially cultivated over the past three centuries, TSB is a relatively new crop • Traditionally sugarbeet is grown in the temperate climates • The total area under TSB still remains at under 10,000 ha • Though agronomically TSB seems promising, its processing is difficult as well as expensive
  2. 2. World production FAOstat World production of cassava root was estimated to be 184 million tonnes in 2002, the majority of production is in Africa where 99.1 million tonnes were grown, 51.5 million tonnes were grown in Asia and 33.2 million tonnes in Latin America and the Caribbean.

  7. 7. Cassava and TSB Cultivation Practices Cassava • Duration 8 to 10 M (can be as high as 36M) • 30N to 30S • Rotation crops: Corn, sorghum, vegetables legumes, rubber, oil palm,(TSB??) • Hand cultivation to semi-mechanised • Relatively easy to cultivate TSB •Duration 5 to 6 months (10 M in RSA at 30S, 1000 msl) •30N and 30S (Highlands aound equator) •Rotation crops: Corn, sorghum, vegetables (Cassava?) •Hand to fully mechanised •Not an easy crop to cultivate
  8. 8. Cassava and TSB Cultivation Cassava • Harvesting round the year possible (Malaysia) • Water requirement: 600 to 1500 mm over 10M • Yield:18-25 M.T. / ha (maximum 50 M.T./ha) • Starch content:20-30% • Ethanol:2,700-3,700 l / ha in 10 months TSB •Harvesting between September and April in northern hemisphere •600 mm over six months •60 – 80 M.T. /ha (maximum 210 M.T. / ha (50 M.T.of white sugar / ha) in 10 months •Sugar content: 14-18% •Ethanol: 4,800 – 10,000 l / ha in six months
  9. 9. Cassava and TSB processing Cassava • Processing is relatively easy • Done from small to very large scale • Is versatile in terms of form of raw material though dried chips is the most preferrred form • Long term storage of chips is possible TSB •Processing is extremely complex •The small beet factories have almost disappeared. Typically Capacity of a modern factory is minimum 10,000 MT/day •Has to be processed fresh • Long term storage not possible
  10. 10. Cassava and TSB : Comparative advantages Time Water Yield Cultivation Processing Flexibility TSB Cassava
  11. 11. Conclusion • Cassava & TSB as rotational crops for Cultivation: - Present date inadequate. Need to conduct experiments / generate data to determine this • Whether they are good partners for procesing - Based on the preliminary analysis it does not seem so
