Traditionally, inorganic chemical-based fertilizers is used for soil management strategies, which can cause public health and environmental threats. Alternatively, bio-fertilizer be to increase the productivity sustainability of without causing pollution. The present study aimed cost-effectively produce using agricultural residues determine shelflife efficacy bioinoculants. We sterilized rice h...

BACKGROUND: Bio-fertilizers are best eco-friendly approach for plant and soil environment. Also, micronutrient element such as iron plays a key role in the formation of chlorophyll and photosynthesis. OBJECTIVES: This study evaluated the effect of growth bacteria and Nano iron fertilizer and ordinary iron fertilizer on some physiological properties of Tritical...

Ten Azotobacter cultures were isolated from the maize rhizosphere and their auxin producing ability was measured colourimetrically. The auxin production by three efficient Azotobacter cultures (Z1, Z3, Z4) was also measured in the presence of filter sterilized L-tryptophan (at 10G, 10G and 10G M). Azotobacter culture Z4 gave relatively higher auxin production and was selected for further experi...

in order to study of effects of integrated biological and chemical  fertilizers on  fertilizer use efficiency, grain yield and related traits to  grain growth of barley (hordeum vulgaris l.), a factorial experiment was conducted based on randomized complete block design with three replications in research farm of the faculty of agriculture sciences, university of mohaghegh ardabili in 2012. tre...

A pot experiment was conducted to determine the effect of compost and bio-fertilizers on the growth, yield and oil constituents of marjoram (Majorana hortensis L.). Forty five days old seedling were transplanted in soil treated with 15 and 30% aqueous extracts of compost and/or biofertilizers (mixture of Azospirillum brasilienses, Azotobacter chroococcum, Bacillus polymyxa & B. circulans) in ad...

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...

Azotobacter strains were isolated by serial dilution method and colonies were viscous, smooth, glistening, and brown to black colour on Jenson's N-free agar. Morphological and biochemical tests showed characteristic features of Azotobacter. Further, molecular analyses revealed the presence of different Azotobacter species viz., A. armeniacus, A. chroococcum, A. salinestris, A. tropicalis and A....

The objectives of this study were to count and culture Azotobacter spp. in sampled soils, to determine the nitrogen (N) fixing capacity byAzotobacter spp. in pure culture and different soils, and to explore the relationships between N fixation capacity of Azotobacter spp. and microbiological properties of soils in Northern Anatolia, Turkey. Statistically significant relationships were found bet...
