Effect of Inoculation by Some Plant Growth Promoting Rhizobacteria (Pgpr) on Production of 'Manzanillo' Olive Trees

The Role of Microbial Inoculants on Plant Protection, Growth Stimulation, and Crop Productivity of the Olive Tree (Olea europea L.)

“…with AMF species (Acaulospora scrobiculata, Gigaspora rosea, and Rhizophagus clarus) could effectively promote the nutritional status and growth of young olive plants. Furthermore, Shaheen and Taweel [21] showed that the reduction of the standard dose of mineral fertilization by 50% in combination with Bacillus polymyxa and fungus yeast Saccharomyces cerevicisiae foliar co-inoculation, increased significantly olive fruit length, weight, and width. The foliar application of S. cerevicisiae combined with AMF root colonization, also showed higher values of leaf N, K, Fe, and Mn content and higher values of auxin and gibberellin contents in these treatments, compared to un-inoculated control plants [41].…”

“…Consequently, several researchers have focused their efforts on the development of alternative, eco-friendly practices aiming to increase olive crop yield, to control biotic threats, and to ameliorate olive tree's health [18]. An essential aspect of sustainable agricultural management is the development and implementation of eco-friendly methods and strategies that promote a soil's biological processes, decrease agricultural inputs [21], and improve soil structure and fertility [22]. Towards this aim, microorganisms of plant's rhizosphere could play a crucial role in plant health and growth [23].…”
