the main objective of this study was to determine the effects of biofertilizers on quantity and quality of essential oil of basil essential oil content, geranial, caryophyllene, caryophyllene oxide and methyl chavicol in essential oil. the experiment was carried out as randomized complete blocks design with eight treatments and three replications at research field of agriculture company of ran ...

abstract in order to evaluate the effects of different organic and biological fertilizers on quantity and quality of essential oil of fennel an experiment was conducted in a completely randomized block design with three replications. the experimental treatments were two organic (compost and vermicompost) and two biological (pseudomonas putida and azotobacter chroococcum ) fertilizers, their all...

The aim of this study was the isolation of Pseudomonas sp. and Bacillus sp. strains from rhizospheric soil and monitoring the impact of two isolates denoted as P12 (Pseudomonas sp.) and B1 (Bacillus sp.) on the parameters of English ryegrass (Lolium perenne) yield and activity of the soil microbial communities. During 2012-2014, a plot experiment was set up following the randomized block system...

In this work we introduce the confluent and various sizes image analysis method (COVASIAM), an automated colony count technique that uses digital imaging technology for detection and separation of confluent microbial colonies and colonies of various sizes growing on petri dishes. The proposed method takes advantage of the optical properties of the surfaces of most microbial colonies. Colonies i...

The N2 fixing bacteria Klebsiella pneumoniae, Azospirillum brasilense, Rhodopseudomonas sphaeroides and Rhodospirillum rubrum, but not Azotobacter vinelandii accumulate the glutamine analogue methionine sulfoximine in the cell. In the accumulating cells methionine sulfoximine inhibits ammonium transport. Accumulation and inhibition are prevented by glutamine.

Biofertilizer can be used to replace chemical fertilizer so that soil quality is maintained and pollution avoided. The study aimed determine the effect of biofertilizers with different compositions microorganisms on growth maize plants. research was carried out in a greenhouse. Maize plants were fertilized by two kinds microorganisms. first biofertilizer contained Azotobacter sp, Azospirillum R...

To boost crop yield on arable land, fertilizers have been extensively utilized. A country may become food-self-sufficient by using more chemical in agriculture, yet chemicals are harmful to the environment and living things. Biofertilizers organic substances that make use of microorganisms increase fertility soil, which helps safeguard soil's health also quality products. provide nutrients thro...
