الملخص الإنجليزي

Brutia pine (Pinus brutia Ten.) and Umbrella tree (Melia azedarach L.) are the most extensively planted in the Iraq, particularly in Kurdistan region.They have high ecological and economic value.

Seedlings of brutia pine and umbrella tree are often produced in our nurseries from seeds, by using river sand or clay as growing media.

Based on the field observation reported by nurseries staff, that raising of planting stocks by using river sand alone need to some over period and consequently much costs to reach a plantable size, therefore, it was necessary to investigate alternative growing media for producing planting stocks in a short time as possible as and decreasing of production cost .

This experiment was carried out during 2014, to determine the impact of various growing media on growth attributes of Pinus brutia Ten.

and Melia azedarach L.

seedlings under field conditions in Malta forest nursery - Duhok, Kurdistan region- Iraq .

Six different media : river sand , clay , river sand + clay(1:1) , river sand + clay(2:1) , river sand + clay + peat-moss(1:1:1) and river sand + clay + ash(1:1:1) were investigated in a complete block design(RCBD).

The results indicated that all tested growth parameters of both Pinus brutia and Melia azedarach influenced significantly by growing media.

Growing medium consisting of river sand + clay + ash (1:1:1) recorded best results for all tested growth parameters of both species (diameter and length of stem; length and number of roots ; shoot and root dry weight) ,except survival percentage which was better in river sand alone.

Based on these results, this medium could be recommended for raising seedlings of these two species in the nurseries
