Investigation agromorphological trait response of wheat to)Pseudomonas fluorescens (and)Thiobacillus thioparus(

This experimant was conducted to investigation of phosphate solubizing and sulfur oxidizing bacteria effects on quality characters of wheat (var. Bahar). a factorial experiment was carreid out based on randomized complete block desigen (RCBD) with 3 replications at Research field of Karaj Branch¡ Islamic Azad University in 2010.Treatments were included Sulfate at two levels (0¡ 300 kg/ha)¡ biological fertilizers in three levels: sulfur oxidizing (Thiobacillus thioparus) phosphate solubizing (Pseudomonas fluorescens strain36 ¡ Pseudomonas fluorescens strain93 ¡ Pseudomonas fluorescens strain187) and Non using fertilizer (control) and phosphorus of source super phosphate triple at 3 levels (0¡ 105¡ 160 kg/ha). In this research¡ effect of treatments was evalute on some traits as number of seed per spike¡ plant height¡ spike length¡ biological yield¡ seed weight¡ number of seed/m2¡ stem diameter¡ seed yield and leaf area. The results showed that effect of biological fertilizer were signifcant defference on Number of seed per spike¡ plant height¡spike length¡ biological yield¡ Number of seed/m2¡ leaf Area (at %1 level) ¡ seed weight and seed yield (at %5 level). The interaction effect of Sulfate×bacteri×phosphorus was significant on spike length (at %1 level) and stem diameter (at %5 level). Result showed that the hieghest No. of seed per spike (52.76)¡ plant height 95.37)¡ spike length (10.55)¡ biological yield (1619.17)¡ 1000 seed yield¡ N.spike/m2 (503.44)¡ stem diameter (6.84)¡ seed yield (960.22) and Leaf Area (18.24) wes resulted from phosphate solubizing bacteria application.
