Objective: The inoculation of substrates with arbuscular mycorrhizal fungi (AMF) is one of the most important effective strategies applied and one of the aims of sustainable agriculture. Methods: This experiment was conducted to evaluate the effects of AMF inoculation (0, 2.5, and 5 W/W) on morpho-physiological traits such as flower and root dry weight, water-use efficiency and antioxidant capa...

Four isolates each of Bacillus and Rhizobium sp were selected and characterized for their P-solubilization and auxin production. All the isolates produced auxin but with different degree of efficacy. The isolates of Rhizobium and Bacillus having maximum auxin production and P-solubilization were selected and further evaluated for improving growth, nodulation and yield of mungbean at two fertili...

abstract- greenhouse experiment was conducted in factorial experiment arranged as a completely randomized design (crd) to evaluate the effect of glomus intraradices, pseudomonas fluorescence and soil drying on different forms of potassium (k) and the changes of clay minerals in a calcareous soil after maize planting. treatments consisted of arbuscular mycorrhizal (am) fungus at two levels: g0 (...

An isolate of the filamentous cyanobacterium Microcoleus sp. was obtained from black mangrove aerial root (pneumatophore) and inoculated onto young mangrove seedlings to evaluate N2-fixation and rootcolonization capacities of the bacterium under in vitro conditions in closed-system experiments. N2 fixation (acetylene reduction) gradually increased with time and reached its peak 5 days after ino...

The benefits of AMF and GPRB of available N and P t o p o t a t o were examined in pot experime n t containing clay loam soil and fertilized with organic matter. Mycorrhizal colonization of potato plants was over whelmed by bacterial inoculation. Results indicated inoculation with GPRB s trains and AMF increased shoot, root and total dry weight of potato plants s ignifican t ly c ompared with s...

The influence of the vesicular-arbuscular mycorrhizal fungus Glomus intraradices (Gi) and superphosphate (P) on penetration, development, and reproduction of Meloidogyne incognita (Mi) was studied on the Mi-susceptible cotton cultivar Stoneville 213 in an environmental chamber at 28 C. Plants were inoculated with Mi eggs at planting or after 28 days and destructively sampled 7, 14, 21, and 28 d...

Phytophthora cinnamomi is a major pathogen of Eucalyptus marginata (jarrah) in Western Australia (23). It can kill trees of all ages through infection of roots (10,27) or by girdling the trunks of 1to 7year-old trees in situations were the collar is ponded (12,19). Field observations have indicated that periods of waterlogging (low oxygen) can result in the rapid death of trees from P. cinnamom...
