Abstract
The study was compared the costs and profits of a mixed rice-fish farming system between landowners and land tenants in Chachoengsao province, Thailand. At the farm level, the average total production cost was 6,118 THB per farm (averaging 20.46 rai), with variable costs accounting for 65.8% and fixed costs accounting for 34.2%. The main cost components included seed costs (416 baht per rai), chemical fertilizers (577 baht per rai), and land-related costs (opportunity costs for owners and rental costs for tenants) (1,535 baht per rai). Profitability analysis found that an average yield of 0.81 metric tons per rai, sold at 16.16 THB per kilogram, a net profit of 12,743 THB per rai, with a breakeven point of 233 kilograms per rai. There was not significantly differed in the overall performance indicators of the two clusters, namely total production cost per rai (p = 0.869), yield per rai (p = 0.823), net profit per rai (p = 0.241), and income per rai (p = 0.246). However, there were significantly differed in landowners who used more on seeds (p=0.029), whereas tenants incurred higher cash costs (p=0.004) and land rent (p<0.001) which obtained better market prices (p=0.027).
