Posetive Effect of Fungi Piriformospora Indica on Fennel Yield, Yield Components under Effectorganic Organic Matter

Application of of mycorrhiza-like fungi and organic matter have important role in crops productivity and yield. In order to study the effect of biofertilizers on yield، yield component and root colonization in fennel (Foeniculum valgare Mill)، an experiment was conducted in 2009 and 2010 growing seasons، teratements were mycorrhiza-like fungi (inoculated and non-inoculated) and fertilizer treatment (nitrogen (90 kg ha-1 N)، cattle manure (10 t ha-1)، mushroom spend compost (10t ha-1)، integrated cattle manure with mushroom spend compost (5t ha-1 CM+ 5t ha-1 SCM) and without manure). The treatments were arranged as factorial in a randomized complete blocks design with ten treatments and three replications. Results showed that treatment manure and fungi significantly affected yield، dry matter، No. Umbel at the each plant، 1000 seed weight and root colonization. Also results shown that the highest yield، 1000 seed weight، umbel at the each plant، dry matter and root colonization were obtained with mycorrhiza-like Fungi. Interaction of fungi ´ nutrition systems was negligible affected all of measured traits. In year 2008 the highest and the lowest yield were obtain from chemical fertilizer and treatment without manure. In year 2009 the highest and the lowest yield were obtain from treatment spent compost mushroom and without manure.
