Many experiments have been conducted to find out the yield potential of rice in several dry land areas. Farmers with limited capitals had difficulties in adopting new technologies which usually need high costs. The gaps between the potential rice yield and the farmer's yield are commonly caused by biological or socio-economical factors. A study was conducted with objective to determine the minimum yield of upland rice using different packages of technology which to the farmers is still profitable. Analysis of variance is used to determine the difference in yield between the use of the high input technology package and the farmer's package. The breakeven analysis was used to determine the minimum yield that should be reached by using each of the packages still profitable. Results of the study showed that differences in using rice variety and weed control caused significant difference in the rice yields. The differences in yield due to the differences in the dosages of fertilizers was not significant. There was a significant difference in yield due to the pesticide dosage used when other factors were used at high levels. With low level of other factors, however the yield differences was not significant. The package 1 could be feasibly recommended to the farmers who have high capitals, while package 4 is suitable for farmers who have limited capitals. Package 2 is adoptable to all farmers.
