Abstract: PurposeThis study aims to assess profitability and determine the factors influencing the use of certified common bean seeds in Mbozi and Momba districts of Tanzania.Design/Methodology/ApproachThe study adopts a mixed-methods approach, integrating both quantitative and qualitative research techniques. It involves analysing production costs, yields, and profitability, alongside gathering farmers' perspectives on use of certified seed. A sample of 340 smallholder farmers was selected using a multi-stage sampling technique to ensure representativeness. Gross margin analysis was employed to estimate the profitability for certified, uncertified and local landraces seed users, while binary logistic regression was used to determine the factors influencing the use of certified common bean seeds.FindingsThe study found that farmers using certified common bean seeds achieved significantly higher yields (619.98 kg/acre) and gross margins of TZS 670,347.61 per acre compared to those using uncertified seeds (330.83 kg/acre) and local landraces (258.56 kg/acre). Logistic regression analysis found membership in farmers group, farmers who received training on bean production, awareness to the existence of certified common bean seeds, income from other sources and productivity (yield) were statistically significant influence the use of certified common bean seeds in the study area.Practical ImplicationsThe results highlight the potential for certified seeds to enhance agricultural productivity and profitability in Tanzania. The findings suggest that promoting the use of certified seeds through policies and awareness campaign could improve the financial outcomes for smallholder farmers, contributing to broader agricultural development.Originality/ValueThis study contributes to the limited literature on the economic benefits and determinants factors influencing the use of certified seeds in Tanzania, particularly in the context of common bean farming. The research highlights the tangible financial advantages of using certified seeds and calls for policies that support their wider use to improve the productivity and livelihoods of smallholder farmers in the region.
