Pegah 81 91 2127 FA Jafar Asghari Seyed MohammadReza Ehteshami Nazli Golestani Mohammad Rabiei Journal Article 2017 03 06 In order to evaluate effect of some of biofertilizers in integrated to chemical and organic fertilizers on quantitative and nutrients density of sorghum forage (Pegah cultivar), a experiment was conducted during 2010-2011 growing season at Rice Research Institute in Rasht. The experimental design was completely randomized block, with three replication. Investigated treatments were including control (without inoculation and without chemical fertilizer), use of fertilizers and without inoculation, seed inoculation with Pseudomonas fluorescens strain 12+Azotobacter chroococcum strain 41 and without chemical fertilizer, seed inoculation with P. fluorescens strain 12+A. chroococcum strain 41 and 50% chemical fertilizer, seed inoculation with P. fluorescens strain 12+A. chroococcum strain 41 and 75% chemical fertilizer, use of vermicompost (6 ton/ha)and without chemical fertilizer,use of vermicompost (6 ton/ha) and 50% chemical fertilizer,use of vermicompost (6 ton/ha) and 75% chemical fertilizer, seed inoculation with P. fluorescens strain 12+A. chroococcum strain 41 and 50% vermicompost,seed inoculation with P. fluorescens strain 12+A. chroococcum strain 41 and 75% vermicompost,seed inoculation with P. fluorescens strain 12+A. chroococcum strain 41 and vermicompost. Fertilizer treatments had significant effect on plant height, leaf area, dry weight of leaf and stem, wet and dried yield of forage, dry matter digestibility of dried forage, crude protein of dried forage, P and Zn content. Results showed that integrated usage of vermicompost and plant growth promoting microorganisms had the highest of amount in all of characteristics except stem diameter. The findings of this experiment showed these microorganisms can adapt themselves based on soil properties, plant genotypes and particularly climate. Improving of the nutritional status in integrated usage of vermicompost and plant growth promoting microorganisms increased quantitative and nutrients density in compared with non-inoculation treatments. Indeed, use of biofertilizers and organic fertilizers can interact positively in increasing plant yield by nutrients uptake especially P, promoting plant growth and secretion of secondary metabolites, too. Generally, it seems that using of vermicompost could improve sorghum performance in addition to reduction of environmental pollution.
