Abstract
In order to investigate the effects of organic fertilizers and mycorrhizae inoculation on yield and yield components of dwarf chicory (Cichorium pumilum Jacq.), an experiment was conducted as factorial layout based on randomized complete block design with three replications at research farm of Ferdowsi University of Mashhad in 2012-2013 growing season. Experimental treatments were all combination of organic fertilizers at four levels (cow manure, humic acid, fulvic acid and control) and mycorrhizae inoculation at three levels (inoculation with Glomus mosseae, G. intraradices and control without inoculation). The results showed that the effects of mycorrhiza inoculation were significant on all studied criteria on dwarf chicory. Application of G. mosseae led to increasing of number of inflorescence per plant by 22% and seed yield by 29% rather than control treatment. Using organic fertilizers improved yield and yield components of dwarf chicory. Application of humic acid and cow manure led to increasing of number of inflorescence per plant, seed yield, and biological yield. It seems that application of organic and biological fertilizers can improve seed yield and yield components of dwarf chicory.
