Abstract

 

This study was designed to investigate the effect of date palm leaves compost (DPLC) individually and/or in combined with plant growth promoting rhizobacteria(PGPR) for controlling faba bean root rot disease caused by Rhizoctonia solani andFusarium solani under greenhouse and field conditions as well as plant growth and yield parameters. The obtained data indicate thatDPLC at different concentrations significantly decreased root rot incidence either under artificial infection in pot or natural infection in field as well as increased growth and yield parameters during growing season 2013-2014. Date palm leaves compost at 8 ton/feddan recorded the highest protection against root rot disease and gave the highest increased of plant growth and yield parameters. On the other hand, PGPR viz.Bacillus megaterium, B. cereus and Pseudomonas fluorescens individually or mixed significantly decreased root rot incidence under greenhouse and fieldconditions. The mixed of PGPR strains more than for controlling root rot disease than used alone of them.  Plant growth promoting rhizobacteria increased efficacy of DPLC for controlling root rot disease in faba bean more than the applied of DPLC or PGPR alone under greenhouse and field conditions during both growing seasons (2014-2015 and 2015-2016) as well as increased of nodulations, growth and yield parameters. The application mixed of PGPR strains and DPLC at 8 ton/feddanrecorded the highest reduction of root rot incidence and increase of nodulations, growth and yield parameters during both growing seasons.
