Choosing the correct planting density is vitally important for maximizing the yield potential of the plantation. For the highest possible yields of good quality fruit, there is an optimum plant density which should be maintained for the life of the plantation. This optimum, however, varies for each particular locality, cultivar, soil type and management level. This experiment was carried out from banana (var. Dwarf Cavendish) with four replications and five treatments consist of (3×2, 2×2.5, 2×2, 2×1.5, 1.5×1.5m) in Zarabad Research Garden is located in 185km western of Chabahar for four years(2005-2008). The experiment was a Randomized Complete Block design. During four years we studied vegetative and generative processes for treatments. The results of combined analysis showed that survival percentage of suckers and number of their leaves werenot significant at the 1% and 5% levels. The spacing of banana plants (2×1/5), (1.5×1.5) were the most survival percentage with 91%, 89.5% and the spacing of banana plant 3×2m was the least survival percentag with 71.25%. The results of combined analysis showed that weight of leaf, plant height, stem diameter, weight and length of banana bunch, lenghth and number of fruits in each bunch were significant at 5%. At distance 3×2m we had the biggest bunches and fruit size. At distance 1.5×1.5m total yield per hectar increased due to the greater number of bunches, however, in put costs per hectar also increased. On the basis of the results gained from this research the best planting distances for establishment of banana garden (var. Dwarf Cavendish) in Zarabad weather conditions is 3×2m (3m between rows and 2m between plants).
