To investigate the effect of seed biological treatment and fertilizer integration on yield and nutrients uptake of turnip (Brassica rapa L.), an experiment was conducted at research institute of rice during 2011 and 2012. The experiment was arranged base on randomized complete block design with three replications. Treatments were involved 9 levels: use of fertilizer and uninoculation, seed inoculation with Azotobacter chroococcum strain 41 and without nitrogen, seed inoculation with A. chroococcum strain 41 and full nitrogen, seed inoculation with Pseudomonas fluorescens strain 12 and without P fertilizer, seed inoculation with P. fluorescens strain 12 and full P fertilizer, seed co-inoculation (with P. fluorescens strain 12 and A. chroococcum strain 41) and without fertilizer, seed co-inoculation and %50 N.P. fertilizer, seed co-inoculation and %100 N. P. fertilizer and without inoculation and fertilizer (control). Investigated characteristics were including plant height, stem diameter, nutrients content (N, P) in plant tissue, dried weight of leaf and tuber and fresh and dried forage yield. The results showed significant effect of seed biological treatment on all of investigated characteristics. This present findings showed that, fertilizer integrated management has important role in enhancement of turnip yield, and it could be suggested that these bacteria have positive effect on forage yield of turnip, and therefore can be used as complementary fertilizer.
