Abstract

In order to study the effects of different NUTRITION SYSTEMS (organic, chemical, integrated) and PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) on on the grain YIELD, seed oil content and fatty acid composition in SUNFLOWER (Helianthus annuus L. cv. Alestar) an experiment was conducted using Alestar cultivar at the research farm of college of agriculture, Tarbiat modares university of in 2007. Five levels of NUTRITION SYSTEMS including F1 (100% organic), F2 (75% organic+25% chemical), F3 (50% organic+50% chemical), F4 (25% organic+75% chemicaL), F5 (100% chemical) in main plot and two levels of biofertilizer I1 (inoculation) and I0 (control) as subplot were used in a split plot arranged in a randomized complete block design with three replications. Results showed that the integrated fertilizer system had higher grain YIELD than the other fertilizer systems (F3›F4›F2›F5›F1). Maximum and minimum oil content were obtained with the F3 treatment and F1 respectively. The oil saturated fatty acids (acid palmitic and acid stearic) decreased significantly, while insaturated fatty acids (linoleic acid and oleic acid) increased significantly in response to raising the FYM-rate. The highest linolenic acid and oleic acid were observed in F3 and F1 treatments respectively. The results revealed that PGPR improved plant productivity and quality in SUNFLOWER seed. The inoculation of PGPR (I1) increased, grain YIELD, oil content and unsaturated fatty acids and decreased saturated fatty acids compared with untreated plants I0.
