Effects of urea fertilizer, organic matter and Plant Growth Promoting Rhizobacteria on N uptake and yield of wheat (Triticum aestivum C.V Alvand)

This research was carried out for the purpose of urea fertilizer, organic matter and PGPR bacteria effects on yield and some growth indices on winter wheat (Triticum aestivum C.V Alvand). This research was carried out with factorial experiment on completely randomized design with 4 replication in greenhouse. Treatments included bacteria 4 levels, without bacteri, A. brasilense, A. chroococum, integrated both of the bacteria, nitrogen fertilizer 3 levels, without urea. 150 Kg/hectar urea, 300 Kg/hectar urea and organic matter two levels without organic matter and 30 Ton/hectar. Bacteria treatments had significant effects on Dry Weight, Tillering and N uptake (P<0.01). Integrated treatments of both bacteria was better than alone. Urea treatment had a significant effects on measured adjectives (P<0.01). Organic matter treatments had significant effect on dry weight (P<.05).
