Introduction
+M
The Mycorrhizal inoculum enhanced the turf grass capability of:
Water stresses tolerance (Allen et al1991,Koske et al 1995)
Phosphorus uptake (Gemma et al.1995 1997)
The chlorophyll content up to 29% (Amaranthus, 2001)

Problem statement
The turf grass loans in the Faculty of Agriculture and throughout Khartoum public loans have dry and hard appearance
The objective of this study
To clarify whether applying the Mycorrhizal inoculum (M) to the turf grass, in a dry region such like Khartoum,
will improve its quality by:
1. increasing the drought tolerance
2. the phosphorus and other nutrient uptake

Part I
The turf loans with the higher Mycorrhizal
association, had higher freshness and greenness
There was no clear evidence that the Phosphorus

The response to Mycorrhiza inoculation was superior in fresh weight and phosphorus uptake compared to the control
and the fertilization treatments
The performance of Mycorrhiza inoculation was better in the non sterile compared to the sterile soil
Conclusion
The Mycorrhiza endo -roots in association with turf grass even in dry regions not only improved the grass growth and its
appearance, but also encouraged the growth of other soil micro-organisms and/ or enhanced the activity of the indigenous
Mycorrhiza
