| dc.description.abstract | A study was carried out to analyze the economics of virus free sweet potato and vine multiplication by smallholder farmers in two selected agro-ecological zones of Tanzania namely; Lake Victoria Zone and Coastal Zone. Specifically, the study aimed at analyzing yields of sweet potatoes and vines production of virus free varieties, analyzing cost and benefits of virus free sweet potato vines production by smallholder farmers and analyzing costs and benefits of sweet potato production of virus free varieties. Primary data were collected from 495 producers of virus free sweet potato and vines by means of survey questionnaire. Sampling procedures involved multistage sampling and simple random sampling techniques. About 362 farmers producing virus free sweet potato and 133 farmers producing vines were chosen from each zone using simple random sampling technique. The findings of the study showed that the benefit of virus free sweet potato production in Lake Zone was TZS 1 284 666 per hectare and that in Coastal Zone was TZS 1 159 525 per hectare. Furthermore, it was found that benefit of virus free sweet potato vine multiplication in Lake Zone was TZS 219 087 per hectare and in Coastal Zone was TZS 305 949 per hectare. The Benefit Cost Ratio obtained from virus free sweet potato production in Lake Zone was 5.04 and Coastal zone was 3.71. The Benefit Cost Ratio obtained from virus free sweet potato vine multiplication in Lake Zone was 2.91 and Coastal zone was 2.11. Furthermore, the study revealed that the yield and benefit of virus free sweet potato variety were relatively higher compared to local variety, hence the likelihood to attract farmers to continue producing sweet potato using virus free sweet potato variety planting material. Therefore, an investment in virus free sweet potato tuber production and vine multiplication is worth undertaking in both Lake Victoria and Coastal zones since farmers generate income and enhance food security. | en_US |
