Abstract

FIELD experiments were conducted at the experimental Site of …….Central Laboratory for Agricultural Climate (CLAC), Agricultural Research Center, Giza, Egypt during 2013 and 2014 seasons. The objective of this study was to investigate the effect of applying rice straw into soil with or without rice straw decomposing fungi (RSDF) and plant growth promoting rhizobacteria (PGPR) under 50 and 100% of recommended NPK on eggplant production. A randomized complete block design was used with three replications. Liquid culture of Trichoderma viride was used as RSDF. Mixture of Azotobacter chroococcum, Azospirillium brasilense, Bacillus megaterium and Bacillus circulans were used as PGPR. The control treatment under this study was application of 100% NPK without application of rice straw. The obtained results showed that growth characteristics, mineral composition and yield component of eggplant cultivar Black Balady were significantly improved by applying 100% mineral fertilizers with rice straw plus PGPR with or without RSDF. Using 50% mineral fertilizers with rice straw plus RSDF and PGPR gave good yield with no significant differences in comparing with 100% mineral fertilizers without rice straw (control). This work shows that incorporation of rice straw into soil with decomposing fungi and plant growth promoting rhizobacteria led to improve the production of eggplant. As well as, reduce the amount of mineral fertilizers and avoid one of the most serious environmental air pollution (Black Cloud), caused by burning rice straw annually.
