التأثير المتداخل للإجهاد المائي و البوتاسيوم و الرايزوبكترين في محتوى حبوب الحنطة من N و P و K و البوتاسيوم في القش

الملخص EN

A Pots experiment was conducted in green house –Soil Science–College of Agriculture–University of Baghdad , at winter season 2010, to study the effect of three water stresses (50, 70 and 90 %) of available water depleated, adding potassium fertilizer and without potassium.

seed were inculated with Rhizobacteren and without inculation.

Soil was sterilized with methyl bromide.

8 kg of soil put per pot.

10 seeds of wheat were sown thinned to 5 plants after germination.

Randomized complete block design (RCBD) was used with three replicates.

N, P, K in grains and K in straw were determinated.

The results showed that : A significantly effect of lower water stress in increasing grains content of N, P, K and K at wheat straw.

Addition of potassium increased these nutrients significantly, so that inoculation of seed.

The interaction between water stress, potassium and Rhizobacterene had a significantly effect of N, P, K in grains and K of straw which were 1.79, 0.33, 0.53 % in grains and 2.71 % in wheat straw respectively.
