	%X In order to study the effect of phosphate solubilization
microorganisms (PSM) and plant growth promoting rhizobacteria
(PGPR) on yield and yield components of corn Zea mays (L. cv.
SC604) an experiment was conducted at research farm of Sari
Agricultural Sciences and Natural Resources University, Iran during
2007. Experiment laid out as split plot based on randomized
complete block design with three replications. Three levels of
manures (consisted of 20 Mg.ha-1 farmyard manure, 15 Mg.ha-1 green
manure and check or without any manures) as main plots and eight
levels of biofertilizers (consisted of 1-NPK or conventional fertilizer
application; 2-NPK+PSM+PGPR; 3 NP50%K+PSM+PGPR; 4-
N50%PK+PSM +PGPR; 5-N50%P50%K+PSM+ PGPR; 6-PK+PGPR; 7-
NK+PSM and 8-PSM+PGPR) as sub plots were treatments. Results
showed that farmyard manure application increased row number, ear
weight, grain number per ear, grain yield, biological yield and
harvest index compared to check. Furthermore, using of PSM and
PGPR in addition to conventional fertilizer applications (NPK) could
improve ear weight, row number and grain number per row and
ultimately increased grain yield in green manure and check plots.
According to results in all fertilizer treatments application of PSM
and PGPR together could reduce P application by 50% without any
significant reduction of grain yield. However, this treatment could
not compensate 50% reduction of N application.
