Abstract

In order to study the effects of drought stress and municipal compost on quantitive characteristics in
peppermint , a green house experiment in a factorial based on a randomized complete block design with four
replications was conducted in 2009 at University of Zabol. Treatments included: three irrigation levels %100
field capacity(control),%80 field capacity(mild stress) and %60 field capacity(severe stress) and four levels of
municipal compost: control(no chemical fertilizer and compost), T1:10, T2:20 and T3:30 tons per hectare.
Results showed that increasing of the municipal compost levels improved significantly the dry and fresh yield,
plant height, tiller number, root dry and fresh weight, essential oil percentage and yield of essential oil .Effects of
different levels of irrigation with superior control(no stress), was significant in all traits. According to the results
achived maximum dry matter(4.51 g/pot) and essential oil yield (8.42 mg/pot) to produced proper at treatment 30
ton per hectare municipal compost and non-stress conditions.
