Evaluation of Yield and Yield Components of Fennel (Foeniculum vulgare L.) With the Combined Application of Nitrogen, Phosphorus and Potassium Supplier Bacteria with Mycorrhizal Fungi in Low-Input Cropping System

The effect of biofertilizers on the seed yield and yield components of fennel(Foeniculum vulgare L.), was studied as factorial experiment based on randomized complete block design with three replications and twelve treatments at the Research Farm of the Faculty of Agriculture, University of urmia, Iran, during growing season of 2015-2016. The first factor included three Landraces (Urmia, Hamdan and Germany) and second factor included four biofertilizers: complete biofertilizers (Azetobarvar1, Phosphatebarvar2, Pota barvar-2, mycorrhizal fungi (Glomus intraradices), compelet biofertilizers mycorrhizal fungi and control. Results indicated that application of biofertilizers enhanced the seed yield and yield components. Among treatments, combined usage of biofertilizers showed that great increasing in studied traits than individual consumption. The highest biological yield (520.38 g.m-2) and seed yield (146.68 g.m-2) were obtained from combined usage of biofertilizers. Germany landrace (142.39 g.m-2) produced higher seed yield, compared to Hamdan and Urmia landraces. In general, results of the present study revealed that the application of biological fertilizers plays a remarkable role in improving seed yield and yield components offennel.
