Interaction Effect Between Glomus mosseae Fungus and Phosphate Rock In Phosporus Availability Increase and Growth of Wheat Plant

Abstract

Pot factorial experiment was conducted,using Completely Randomized Design (CRD) with silty loam soil in winter season of 2011-2012 in lath – house at the College of Agriculture University of AL-Muthanna to study the effect of mycorhiza fungus Glomus mosseae in phosphorus availability and growth of wheat plant. Three levels used of rock phosphate (0 , 60 , 120 kg P.hr-1 ) and inoculation of soil, and without inoculation by mycorrhiza by three replication. Results showed that the application of rock phosphate with mycorrhiza fungus caused significant increasing in height of the plant, shoot dry matter, root dry matter and available phosphorus in soil to two growth period where increase percent which was 22.16 , 16.94% to height of plant and 28.68 , 58.46% to shoot dry matter and 24.39, 34.26% to available phosphorus in soil to first and second growth period succession compared with control treatment.
