Abstract EN

This experiment was carried out in the Biology Dept.

- Collage of Education for Woman –University of Anbar during the Winter Season 2012-2013.

The aim was to study the effect of several levels of magnesium (0, 100, 150, 200 and 250)mg.

L-1 Mgo, Application foliar spray on some growth parameters and yield components of wheat variety (Fatah) which include Nitrogen, Phosphor, Potassium, magnesium, plant height, No.

of grains, weight 1000 grain.

The experiment has also included (CRD)was used at three replicates for each treatment.

Flowerpots with a capacity of (8) kg of soil have been prepared: Fertilizers have been added to wheat (Triticum aestivum L.

) according to recommendation.

the sprayed on plant leaves, seven times each levels of added magnesium, one spraying for each ten days.

The results could be summarized as follows.

Increasing levels of magnesium addition had significantly affect; addition magnesium level at 200 mg.

L-1.

Potassium value was; (3.72 mg.

100 gm-1), Phosphor (0.81 mg.

100 gm-1), Nitrogen (2.25 mg.

100 gm-1), magnesium (0.97 mg.

100 gm-1), Length of plant ( 81 cm ), No.

of grains ( 71 grain.

Spike-1 ), weight 1000 grains (45.7gm.
