To examine the effect of crop growth enhancer bacteria on quantitative and qualitative yield of safflower, an experiment in randomized complete block design was conducted in eight levels with four replications. Bacterial factor consisted of control (absence of bacteria), AzotobacterChroococcum,AzospirillumBrazilians, Pseudomonas Fluorescens, AzotobacterChroococcum+Azospirillum Brazilians, Azoto...

The objective of this study was to evaluate the biofertilizers effect in Panicum maximaum (cv. Mombaza) and Brachiaria brizantha tropical grasses production. Microorganisms were obtained rhizosphere plants. To establish an effective symbiosis with native strains Azospirillum, Azotobacter mycorrhizal fungi, experiments carried out greenhouse field. used combined (CC), semisolid medium Nitrogen f...

The study “Influence of bio-fertilizers on vegetative growth, flower quality and bulb yield gladiolus (Gladiolus grandiflorus L.)”, field experiments conducted during 2020-21. Bulbous is a very well-liked plant. Pliny the Elder (2379 AD) first used term "gladiolus" to refer blade's sword-like form (Latin word means sword). Gladiolus delicate perennial herbaceous plant that may be cultivated fro...

In this study, aimed to investigate the effect of bacterial fertilizer: A (Bacillus spp., Trichoderma spp. ), B (Azorhizobium, Azotobacter and Azospirillum) C (Azotobacter Bacillus Pseudomonas putida) on soil carbon mineralization. On application A, fertilizers sterilized control soil, whose initial mineralization rates is 1.1%, 5.12%, 3.54%, 10.78% were respectively recorded. According these r...

Area around the root zone i.e. rhizosphere is a rich environment for plant growth promoting bacteria (PGPR) which can be utilized in many way to improve the growth of crop and yield. In agriculture one of the limiting factors is providing plant nutrition particularly nitrogen and phosphorus to the crop. Different Plant-Growth Promoting Rhizobacteria (PGPR) such as Azospirillum, Azotobacter, Bac...

In order to study the response of concentration and composition of essential oil of coriander (Coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in Damavand of Iran in 2010. The factors were cattle...

potassium is an essential plant macronutrient. various microorganisms including bacteria and fungi, algae, yeast and mosses are able to decompose silicate minerals and to dissolve nutrient such as k, fe, zn and si. aamong them bacteria are more important. the aim of this study was to determine the ability of microbial populations for releasing soil potassium. this study was carried out as a fac...
