The study centered on the economic analysis and determinants of profit from seed yam Dioscorea spp. (Dioscoreales: Dioscoreacea) production in South Eastern Nigeria. It specifically ascertained  the socio-economic characteristics of the producers, determinants of net production income, profitability and constraints to seed yam production in the area. Multi-stage random sampling was used in selecting 180 seed yam farmers from the two sampled states. Structured questionnaire were used in collecting primary data, while means, percentages, frequency distributions, enterprise budgeting and multiple regression analysis were employed in data analysis. Results indicated that majority of the respondents were males, married and attained one form of education or another. Seed yam output and net production income were significantly and positively influenced by gender, educational levels, marital status, farm size, cost of production and amount of credit. The enterprise was profitable given the positive values of gross margin, net farm income, mean net farm income and net return on investment of N2,116, 548, N2,047, N179,11,373 and 0.76 respectively. Production was most seriously constrained by high labour cost, lack of capital and dearth of modern farming technologies. It was recommend that policy measures geared towards supply of machineries at subsidized rate, increased access to soft loans and provision of quality extension services be put in place to help mitigate the problems and enhance production level and profit.

Key words: Economics analysis, Nigeria, profitability, seed yam, socio-economic determinants
