Abstract

The influence of three Vermicompost (VC) rates and three N2-fixing bacteria on the growth, yield attributes and yield of peanut on the low nutrient soil. Three VC rates consisted of 0, 5.0 and 10 tons/ha, and three bacteria were inoculated in the experiment: E. asburiae, K. quasipneumoniae and E. cloacae. The impact of VC rates and three bacterial species was on the growth, yield attributes and yield of peanut. The studied results proved that application of different VC rates was a little impact on the nitrogen fixing ability of three bacteria, but high efficiency on the nodulous number and weight of peanut. Rate of 10 tons VC/ha combined with E. asburiae inoculum significantly obtained the highest yield attributes and yield of peanut, while the lowest yield component and yield of peanut observed without VC application and E. cloacae inoculation. The differences between rhizosphere bacterial species and different VC rates was better than that caused by the inorganic fertilizer. The main aim of this study is to optimize organic manures management and apply nitrogen fixing bacteria to maximize soil fertility and yields while lessening the usage of inorganic fertilizer and maintaining good soil.
