However, production of bean crops has been limited by lack of quality seeds. Tanzania adopted Quality Declared Seeds (QDS) production system in order to promote quality seeds, yet QDS accounts for relatively very small amounts of seeds sales in the country. The overall objective of the study was to generate evidences that will contribute towards sustainable distribution of QDS bean seeds. Specifically the study identify profit obtained by QDS bean seed producers; compare gross margins obtained by QDS bean seed users and non-users; identify factors that influence profitability of bean grain producers; determine factors which influence purchase decision of QDS seeds. Gross margin analysis was used to evaluate profit obtained by QDS bean seed producers and bean grain producers. Furthermore, regression analysis was employed to identify of factors that influence profit obtained by bean grain producers and it was also employed to determine factors that influence the purchase of QDS been seeds in the study area. The gross margin of QDS bean seeds sells obtained by producers of QDS bean seeds was Tsh 383 256 per acre which gives 54% of the value of sales on average. There was significant mean different in gross margins among QDS bean seed users and non-users at p<0.01 were by QDS bean seed users obtained higher margins than QDS bean seed non-users per acre. Regression analysis indicate that agricultural training, gender and kind of bean seed used were the major factors influencing profitability of bean grains production (p<0.1). Agriculture training, extension service contact, income and membership on credit society were the factors influencing purchase decision of quality declared bean seeds (p<0.05). The study recommends improvement of agriculture training, extension service, availability of the market information and introduction of Irrigation schemesenMarketing-quality bean seedsBean seedsTanzaniaQuality Declared Seeds (QDS)Marketing of quality declared bean seeds in central northern zone of TanzaniaThesis
