Analysis of arroz (rice) production in Nicaragua, a detailed study of costs and returns

Initial emphasis was to give an overall perspective of the data for the average farm in the sample. This budget is set forth in Table 2. Next the analysis of the costs and return were made by: Size (7 groupings), region (5 groupings), ecology (2 groupings), and technology (3 groupings). In addition to the above, special attention is given to physical labor information. These data are presented in Table 7. Statistical tests of Analysis of Variance were made and summarized in the Appendix. Gross Income, Yield, Total Labor, and Total Cost were analyzed as to differences in Size, Region, Ecology, and Technology. Generally, statistically significant differences were found in all strata -- except for Ecology (note however that only 2 levels of Ecology were present). Coefficients of Variation (COV), F values and significance levels are set forth in Appendix Table 1.
