This study was proposed to project future production of cassava due to introduced cassava processing technologies in Mikongeni (Kibaha district) and Tongwe village (Muheza district) in Tanzania. Primary data were generated from 120 consumers who were randomly selected with the use of questionnaire, focus group discussion and experimentation. The study projected the future trend of production for cassava using goal programming approach and indicated that about 128 571.4 tonnes (an increase of 60.7% per year) can be produced per annum in the two districts, if farmers use the said technology in full scale. The study recommended that the farmers have to be informed on the growing demand of the mechanically processed cassava products, thus the need to meet this demand.
