| Abstract | ||
| ABATRACT : 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 : ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ 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. | ||
