Abstract:
Using productivity index for investigating a firms’ performance makes it possible to
evaluate efficiency of the production system and cost at the same time. In this study the
Total Factor Productivity (TFP) of several sugar cane varieties in Imam Khomeini
Cultivation and Processing Center in Khuzestan Province is compared. Two hundred and
forty eight farms are categorized on the basis of variety years old and then Tornqvist-Tiel
Productivity Index is employed for calculating TFP for each sugar cane farm. The
investigated sugar cane varieties include CP57-614, CP69-1062 and CP48-103. Results
revealed that year long utilization system gained the lowest TFP among utilization
systems in all the mentioned varieties. The most suitable utilization system according to
the TFP index is biennial for CP57-614 variety, triennial for CP69-1062 and five years for
the CP48-103 variety. Triennial CP57-614 variety has the most partial productivity in
fertilizer. On the other hand, the six year long plant of the forgoing variety exhibits the
largest partial productivity in water. The largest partial productivity in machinery is
shown in biennial CP69-1062 variety. Among these varieties, triennial CP48-103 one has
the largest partial productivity per unit area cultivation.
