Field experiment was conducted during winter season of 2010 – 2011 at medicinal plants garden of pharmacy collage of Baghdad University to evaluation the effect of planting spaces between plants on growth parameters and volatile oil quantity and quality .
The results were showed the space at 40cm between plants was gave a highest values of total fresh yield , total dry yield , fresh leaf weight , dry leaf weight and number base of branches per plant were reached to 1187 kgha¹ , 448.18kgha¬¹ , 518 kgha¬¹ , 216 kgha¬¹ and 25 branche per plant respectively .
The quantity and physical properties of leaf volatile oil also increasing with increasing the planting spaces among plants . The highest values of volatile oil percentage , volatile oil yield per hectar , specific gravity , density and refractive index and these values were reached to 2.75% , 14.24Lha¬¹ , 0.980mg /microliter , 0.941mg/microliter and 1.520degree respectively at 40cm as planting space between plants .
