Abstract :
In order to Study of most suitable stringing method of burley tobacco using sewing machines, this research was carried out in a factorial experiment based on RCBD with three factor including thread length in four levels ( 1.5, 2, 2.5, 3 meters), seam place in two levels (petiole and between petiole and leaf blade) and picks in three levels (pick 1, 2, 3) with 24 tretments and 3 replications in Tirtash Research and Education Center in 2011. Traites of labor costs for stringing and manipulation, stringing and manipulation time and leaf loss ratefrom sewing machine were investigated. Variance analysis showed labor costs and time for stringing were affected by thread length and picks and there were significant differences between them in 1% probability level. means comparison of interaction between thread length and seam place and picks showed that the lowest time and costs stringing related to thread length of 3 meters and petiole and between petiole and leaf blade and pick3
