In order to study the combined effects of chemical and biological fertilizers on quantitative and qualitative characteristics of wheat cultivars in Shoushtar, this research was carried out as split-plot based on randomized complete blocks design with three replications in 2014-2015. The main plots were comprised of 4 fertilizer levels including 100% chemical fertilizer (nitrogen + phosphorus),75% chemical fertilizer along with biological fertilizer (fertile 2 and azotobacter 2), 50% chemical fertilizer along with biological fertilizer (fertil2 and azotobacter2),and solely biological fertilizer, and the sub plots included three wheat cultivars (chamran, varinak, and S83).The results showed that interaction between fertilizer and cultivar was significant on all grain traits, grain protein, seed nitrogen percentage and seed phosphorous content. The highest biological yield and grain yield, with an average of 12 tons per hectare and 6 tons per hectare, were related to 100% fertilizer treatment and Chamran cultivar.The highest percentage of protein, nitrogen percentage and phosphorus percentage were obtained from 100% fertilizer application. In most cases, there was no significant difference between treatments of 100% and 75% of fertilizer and biological fertilizer for measured traits. In general, it can be stated that using 75% chemical fertilizer and biofertilizer treatment, can be used to reduce the use of chemical fertilizers.
