Abstract

In order to study the effect of PLANTS GROWTH PROMOTING RHIZOBACTERIA and nitrogen chemical fertilizer on quantitative and qualitative characters of SUNFLOWER (Helianthus annus L.) an experiment was conducted in Islamic Azad University-Karaj Branch in2009. Experiment performed factorial based on CRBD with three replications. Experiment in clouding of four levels of NITROGEN FERTILIZERs (0, 54, 108 and 161 Kg.N/ha) and four level of plant growth PROMOTING RHIZOBACTERIA including control, Nitroxin (Azotobacter, Azospirillum), Biophosphorus (Bacillus, Pseudomonas) and also combined fertilizers (Nitroxin + Biophosphorus). Results showed that application of plant growth PROMOTING RHIZOBACTERIA increased SEED YIELD, biologic yield, and plant height in compare with control. Combined biological fertilizers increased higher under studied traits. Maximum SEED YIELD (26.68% increased) obtained in combined biological fertilizer (Nitroxin+Biophosphorus) treatment with 2516 kg/ha in compare with control (1850 kg/ha). Nitrogen chemical fertilizers treatments showed significant effect on protein percent. Interaction of treatments showed significant effect on oil percent. Results showed application of PGPR agriculture has important role in improvement of growth and yield of SUNFLOWER.
