Effect of Application of Organic and Biological Fertilizers on Seed Yield and Yield Components of Dwarf Chicory (Cichorium pumilum Jacq.)

In order to evaluate the effects of organic and biological fertilizers on seed yield and yield components of dwarf chicory, a field experiment was conducted at the Agricultural Research Station, Ferdowsi University of Mashhad during growing season of 2011-2012. The experimental layout was factorial based on randomized complete block design with four replications. The experimental treatments were all combination of organic and chemical fertilizers factors (Compost 4 t/ha , vermicompost 4 t/ha , urea fertilizer 130 kg/ha and control ) and biological fertilizer factor (Biosulfur biofertilizer pure sulfur 100 kg/ha and control). Results indicated that studied factors and their interactions had not significant effect on morphological traits (plant height, number of tiller per plant, number of branch per plant) and on yield components of seed such as: number of seed per inflorescence, 1000-seed weight and HI. The Results showed that organic and chemical fertilizers factor had significant effect on number of inflorescence per plant, number of seed per plant, biological yield (p
