in order to study the qualitative and quantitative yield and some agronomic characteristics of sunflower (helianthus annus l.) in response to seed inoculation with pgpr under various levels of nitrogen fertilizer, a factorial experiment was conducted based on a randomized complete block design with three replications in field experimental university of mohaghegh ardabili during growing season o...

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 ...

As a staple in Indonesian diet, rice demand increase along with the population growth. Therefore, order to fulfill continuous increase, researches were conducted land productivity. The of growth and productivity upland application Azospirillum sp. Azotobacter compost, Azolla, bran carrier studied. Nitrogen fixer applied as biofertiliser mean supply available nitrogen for This research was Cipar...

Diazotrophs that carry out the biological fixation of atmospheric dinitrogen (N 2 ) replenish biologically available nitrogen (N) in soil and are influenced by input inorganic organic substrates. To date, little is known about effects combined substrate addition N fertilization on diazotroph community composition structure purple soils. We investigated straw mulching communities quantifying seq...

Seasonal variations of population dynamics of free living nitrogen fixing bacteria, Azospirillum in relation to chemical parameters in Manakkudi mangrove ecosystem was assessed in root and rhizosphere soil samples of mangroves and mangrove associated plants. In rhizosphere soil and root samples, the counts of Azospirillum were recorded maximum in Acrostichum aureum as 8.63 +/- 0.92 x 10(4) and ...

potassium is an essential plant macronutrient. different microorganisms including bacteria, fungi, yeast, algae and mosses are able to decompose silicate minerals of soil and to dissolve nutrient such as k, fe, zn and si, among them bacteria are more important. the aim of this study was to investigate the influence of two bacteria (azospirillum lipoferum and azotobacter chrococoum) on soil avai...

Abstract Endophytic bacteria have been reported to roles as biocontrol agents and plant growth promoters. The application of endophytic in the form mixed culture [consortia] will provide better effectiveness than when applied alone. This study aimed obtain a consortium that is effective biological control for purple blotch [ Alternariaporri ], promote yield shallots. research was arranged compl...
