In this project precision planting method has been tested and evaluated for planting sugarcane billet. For this purpose a single devise known as “billet planting simulator” built and two metering devise were tested. For this research three different treatments that were applied: forward speed in three levels of ?, ? and ? Km/h, Billet transferring system in two levels of angled surface and conveyor and metering devices in two levels of toothed shaft and star wheel model. Factorial design based on Randomized complete design with three repetition were used. Four indexes had been measured and calculated which consist of: quality of feed index, precision index, multiple index and miss index. Teethed Shaft showed higher multiple indexes while star wheel showed higher miss index. Two metering devise had no significant differences in quality of feed index. In forward speed has been found that higher speed means less desirable planting. It also cleared that using conveyor with positive billet feed to metering devise, had significant rising in good planting indexes. Best mode can be found with QFI index and precision index. By using star wheel devise and conveyor with ? Km/h speed the best planting can be reached. In fact it seems that using star wheels, conveyor and low speed is essential properties of a suitable precision billet planting system.
