Determination of timeliness cost of machine operation in different stages of sugar beet production in Fars province

To determinine the timeliness cost of machine operation, farm-level data were collected from random sample of 227 sugar beet farms located in the three major districts of Fars province of Iran: Eghlid, Marvdasht and Fasa in 2006. The results showed that timeliness cost of tillage practices (plough and land leveling), applying fertilizers before planting and timeliness in seed planting per everyday lag were 12237, 3147, 881 and 2622 Rials/ha respectively. Timeliness cost of machine operation in stages of applying chemical fertilizers after planting, applying chemical pesticides and cultivation per everyday lag were 881, 1101 and 3671 Rials/ha respectively. The results of production elasticity indicated a significant negative relationship between timeliness of tillage practices, machine operations (such as plough, land leveling, planting and …) and yield of sugar beet.
