The present investigation was carried out during winter of 2018-2019 at the Horticulture Farm Post Graduate College, Ghazipur. experiment laid in Randomized Block Design with three replications. Ten treatment combinations viz. T1-Control (100% Recommended dose NPK), T2-75% NPK + 25% Azotobactor, T3-50% 50% T4-25% 75% T5-75% PSB, T6-50% T7- T8-75% Azotobactor T9-50% PSB and T10-25% PSB. It can b...

Microorganisms in the rhizosphere mediate the cycling of nutrients, their enhanced mobilisation and facilitate their uptake, leading to increased root growth, biomass and yield of plants. We examined the promise of beneficial cyanobacteria and eubacteria as microbial inoculants, applied singly or in combination as consortia or biofilms, to improve growth and yields of okra. Interrelationships a...

An experiment was carried out during two subsequent years, i.e., 2009-10 and 2010-11 to study the influence of Azotobacter, vermicompost on growth, flowering, yield and quality of strawberry cv. Chandler. There were nine treatments comprising two levels each of Azotobacter (6 and 7 kg/ha) and vermicompost (20 and 30 t/ ha) and their combinations along with one control, replicated thrice in rand...

We report the complete genome sequences of Azotobacter vinelandii mutant strain CA6 and its parent wild-type strain, CA. When fixing nitrogen, strain CA6 displays slow growth and impaired molybdate uptake, tolerance to tungstates, and production of hydrogen gas, compared to results for strain CA. Comparing these genome sequences may provide a genetic basis for these mutant phenotypes.

In 1923 a 20-year experiment was begun in an effort to gain information on the following points: (1) The factors that influence the longevity of Azotobacter when introduced into a soil from which it is normally absent; (2) the effect of introducing and maintaining an Azotobacter flora in such a soil upon the crop-producing abihty and the nitrogen balance of the soil. The recent comprehensive su...

The present study was carried out to investigate biochemical responses of marigold (Calendula officinalis L.) to Bio-organic fertilizers. Effects of co-inoculation of two plant growth-promoting rhizobacteria (PGPR) (Azotobacter sp.145PI and Azospirillum sp.AC49I), humic acid (HA) (10 kg ha−1), vermicompost (VC) (7 T ha−1) and combinations of these treatments were evaluated in two marigold culti...

Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Nitrogen has been found to increase the content of alkaloids in some of the medicinal plants. Objective: The aim of this study was to compare the effects of nitrogen bio-fertilizers, conventional nitrogen fe...

Aims: To evaluate the effect of different nutrient management practices on growth, yield and attributes wheat.
 Study Design: Randomized Block Design (RBD).
 Place Duration Study: The experiment was conducted during Rabi season 2016-17 at Instructional Farm Acharya Narendra Deva University Agriculture & Technology, Nagar, Kumarganj, Ayodhya (U.P.)
 Methodology: consisting 10 ...

A pot experiment was carried out at screen house, Faculty of Agriculture University Maiduguri to compare the effect NPK, bio-fertilizers and manures applications on growth nutrient uptake by maize. The consisted 9 treatments combined application NPK half full recommended rates for maize, Azotobacter chroococcum, Bacillus megaterium Pseudomonas fluorescence biofertilizers cow dung poultry replic...
