environmental problems associated with the excessive use of chemical fertilizers and abiotic stresses due to soil pollution by heavy metals have encouraged use of biological fertilizers in modern agriculture. in order to protect environment and reduce the tension caused by heavy metals, it is essential to use biofertilizer in crop production. to assess the effects of biofertilizers on yield and...

the high cost of fertilizers in farming systems, soil pollution and degradation of soil are factors that caused to full use of available renewable nutrient sources of plant (organic and biological) with optimal application of fertilizers in order to maintain fertility, structure, biological activity, exchange capacity and water-holding capacity of the water in soil. therefore, in recent years, ...

Phosphorus (P) is one of the major essential macronutrient for plant growth. Phosphate solubilizing bacteria (PCB) is a group of heterotrophic bacteria capable of solubilizing organic and inorganic phosphorus from insoluble compounds, releasing phosphate available for plant uptake. In this study endophytic bacteria were isolated form nodules of French bean grown in different intercropping syste...

Globally, rejuvenation of soil health is a major concern due to the continuous loss fertility and productivity. Soil degradation decreases crop yields threatens global food security. Improper use chemical fertilizers coupled with intensive cultivation further reduces both yields. Plants require several nutrients in varying ratios that are essential for plant complete healthy growth development ...

In order to prepare the multi-functional biofertilizer, thermo-tolerant phosphate-solubilizing microbes including bacteria, actinomycetes, and fungi were isolated from different compost plants and biofertilizers. Except Streptomycesthermophilus J57 which lacked pectinase, all isolates possessed amylase, CMCase, chitinase, pectinase, protease, lipase, and nitrogenase activities. All isolates cou...

Marginal soil is infertile caused by various factors, one of which the excessive accumulation heavy metals. FOBIO microorganism-based biopesticide formula containing phosphate solubilizing bacteria expected to be used reduce excess metals in soil. Brasica rapa L. a variety resistant Pb metal stress and absorbs more into root tissue than leaf with help microorganisms. This study aimed determine ...

A study was performed to investigate the efficiency of rhizobacteria on solubilization of rock phosphate and their assimilation by wheat plants in quartz sand potted experiments. Two phosphate solubilizing bacteria, P. fluorescens and Serratia sp. were encapsulated in sodium alginate and potato starch beads and selected to investigate the variation on pH values, the enzymatic activity of alkali...

The use of phosphate solubilizing bacteria as inoculants simultaneously increases P uptake by the plant and crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium are among the most powerful phosphate solubilizers. The principal mechanism for mineral phosphate solubilization is the production of organic acids, and acid phosphatases play a major role in the mineralization of org...

To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...
