This study was carried out on a randomized complete block design with three replications in a field experiment of University of Agricultural Sciences and Natural Resources of Khuzestan in 2019. The main plot included different planting pattern with 4 planting patterns (flat- line,flathole, Row- line and Row- Hole) and sub-plot including rhizome rates per hectare at 4 levels (700, 1400, 2100 and 2800 kg rhizome per ha). The results showed that with increasing rhizome rates, total dry weight of peppermint increased. So that the dry weight of peppermint in flat condition was higher in both cultivars in linear and hole pattern than row pattern. The highest (0.13) slope of peppermints height was obtained for flat- hole pattern and the lowest was related to row- linear cropping pattern. It is possible that flat patterns with less growth space of weed and reduces of weeds yieldwill increase peppermints growth.
