Field experiment was carried out under farmer’s field during 2017 and 2018 main cropping season at Gimbo district in Kaffa zone, South-West Ethiopia. The objective of this study was to determine the appropriate seed rate on grain yield and yield components of upland rice varieties. The experiment was carried out using randomized complete block design with three replications. Five levels of seed rates (60, 80, 100, 120 and 140 kg ha-1) and three levels of varieties (Nerica-4, Suparica-1 and Local check) were studied. The main effect of seed rate and variety had significant (p<0.05) effect on all the studied parameters. However, the interaction effect of seed rate and variety had only significant for number of panicles and grain yield. The pooled results revealed that Nerica-4 and Suparica-1 were produced the highest grain yield of 4553.9 and 4173.9 kg ha-1, respectively at the rate of 80 kg ha-1 in the location. Increasing seed rate above 80 kg ha-1 had significantly decreased the grain yield. The correlation analysis was also made to perceive the relationships between grain yield and yield components. Thus, number of panicles, filled spikelets per panicle, plant height and panicle length had positive and significant correlation with grain yield. In addition, partial budget analysis was also made to discern the profitability of the treatment combinations in the location. Overall, growing Nerica-4 and Suparica-1 at the rate of 80 kg ha-1 was optimum to maximize grain yield and economic benefit. Therefore, it can be suggested for production.
