| Abstract | ||
| The purposes of this study were to estimate cost and benefit for owners of harvesters and to determine profitability indexes. This study was carried out in agricultural farms in Tehran province, Iran. Using split plot in a completely randomized block design with three replications, assuming that current combines were economically acceptable. To find out if the assumption proved, we used partial budgeting technique including net present value (NPV), economic and non-economic test for substitution of harvesters under mean and maximum harvesting condition and marginal rate of return (MRR). In order to determine if differences of costs and incomes were significant; analysis of variance of variables and L.S.D. were used. Four types of combines were tested: New Holland (TC-56), John-Deer (JD-1165), John-Deer (JD-955) & Class-S 68. Economic analysis revealed that JD-955 combine, compared with other combines, had showed lowest cost and highest profits. Marginal rate of return (MRR) for substitution of JD-955 combine, instead of other combines was estimated more than 73.9%. In maximum harvesting condition, New-Holland (TC-56) combine proved more profitable. Marginal Rate of Return (MRR) for substitution of New-Holland (TC-56) combine instead of other combines was as high as 79.2%. A significant difference detected between costs of treatments, but no-significant difference between income of treatments in 5% level. | ||
