Chemical fertilizers are gradually being replaced with new biological fertilizers, which can improve the soil and microorganisms. In this experiment, leguminous forage (Medicago sativa cv. Beilin 201) was used as research object. By measuring alfalfa root systems properties using high-throughput sequencing technology, we investigated effect of (rhizobial) fertilizer at different concentrations ...

Background: Symbiotic association with different microbes is an integral and ecologically vital component of legumes. Most previous studies focused on sole application microbial agents, limited investigating the effects co-inoculation agents under tillage practices soil properties. The current study aimed to assess effect practice seed treatment biofertilizers inoculations chemical properties n...

in order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of goldasht spring safflower cultivars (carthamus tinctorius l.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the agricultural research station of islamic azad university of roudehen branc...

The article presents the results of optimizing design and regime parameters biogas plant original design. values temperature process thermophilic anaerobic digestion substrate, duration its mixing, number revolutions heat exchanger-mixer, at which maximum yield biofertilizer is ensured, have been established.

The formation and sedimentation of akinetes of Anabaena cylindrica were analyzed quantitatively to identify practical strategies for removing or harvesting akinetes. The critical iron concentration for development of vegetative cells of this cyanobacterium into akinetes was between 0.060 and 0.240 mg/l. Before germination, approximately 10% of the total akinetes that were formed in trichomes se...

Cyanobacteria contribute significantly to the maintenance of flooded rice field fertility. In this investigation, the protective effect of osmolytes and antioxidative enzymes was studied on the paddy field cyanobacterial biofertilizer; Anabaena variabilis exposed to Malathion pesticide. With increasing concentration of malathion the test organism showed increased free radical mediated toxicity....

Microbial biofertilizers are becoming an effective tool for sustainable agriculture by means of the reduction of the use of chemical fertilizers. However, the knowledge of each specific plant–microorganism interaction is essential for a correct application. In this study, we analyzed the in vitro plant-growth-promotion mechanisms of a Rhizobium leguminosarum strain named PEPV16 isolated from Ph...

Gluconacetobacter diazotrophicus is a gram-negative and endophytic nitrogen-fixing bacterium that has several beneficial effects in host plants; thus, utilization of this bacterium as a biofertilizer in agriculture may be possible. G. diazotrophicus synthesizes levan, a D-fructofuranosyl polymer with β-(2→6) linkages, as an exopolysaccharide and the synthesized levan improves the stress toleran...

Earthen pots experiments were conducted for the evaluation of nitrogen fixing potential of three indigenous Bradyrhizobium japonicum isolates and one commercial inoculum (Narmada biofertilizer) in three commonly grown soybean cultivars viz., JS-335, JS-9305 and JS-7322. Nitrogen fixation was assessed in terms of root nodules number, root and shoot length and their dry weight. Results indicate t...
