Abstract:

The present investigation was carried out at the Vegetable Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh (India) during Rabi of the year 2009 and 2010 on alluvial soil to assess the effect of Pseudomonas fluorescens and humic acid in combination with three different levels of mineral fertilizer fertilizers on microbial dynemics in alluvium soil. All inoculated treatments in both years of experiment gave significantly greater microbial population and enzymetic activities compared to control at harvest of cabbage crop. The highest microbial population and enzymetic activities were caused by 100% fertilization with Pseudomonas fluorescens + humic acid which showed its significant superiority over rest of the treatments except with 75% RDF + Pseudomonas fluorescens + humic acid, 100 % RDF + Pseudomonas fluorescens and 100 % RDF + humic acid in both experiments. The lowest microbial population and enzymetic activity were found with 100 % RDF as control which was statistically at par with 50 % RDF + Pseudomonas fluorescens and 50 % RDF + humic acid in both year of experiments. Separately inoculation of Pseudomonas fluorescens and humic acid with fertilizer, humic acid gave higher microbial population, dehydrogenase and urease enzymetic activity and alkaline phosphatase activity with P. fluorescens inoculation in cabbage rhizospheric soil during both years of experiment at harvest.


Keywords: Microbial population, Enzymetic activity, Pseudomonas fluorescens, Humic acid and mineral fertilizer.
