pistachio trees such as other fruit trees need that trained in especial and adequate form in juvenile stage. Training form affected vegetative growth and productivity.There are any form of training for pistachio trees in Iran. . This project was done in Rafsanjan area ( Iran's Pistachio Research Institute) as randomize compelet block design with two factors Cultivar treatment was main factor in tree level(Akbari,Ohadi and Kalle- ghochi) and training methods were second factor in four level(open center in 2 treatment,modified leader and control).This project was carrid out for 8 years and included, seed propagation, plantation, budding, beading and training treatment in juvenil stage.We measured some vegetative charactristic such as: tree higeth, canopy width and growth rate in Current shoots. Records were analysed with MSTATC program and mean comparised in Duncan Multiple range test.Results showed that there were no significant differences in tree higeth and growth rate in current shoots in different treatments. Canopy width of Kallh-Ghochi cuItivar was more than Ohadi and Akbari cultivars and control treatment was more effective on canopy width comparison with other form treatments.
