Bio-activation of rock phosphate vis- a- vis seed treatment with phosphorus solubilizing microbes (PSM) in enhancing P nutrition in cowpea and ragi
Year: 2010
Type: article
Abstract: A greenhouse experiment was conducted to study bio-activation of rock phosphate vis-a-vis seed treatment with phosphorus solubilzing microbes in enhancing P nutrition in cowpea and ragi. Bacillus megaterium and Aspergillus awamori were used to bio-activate Udaipur rock phosphate URP and seed treatment. In both the crops higher concentration of chlorophyll was noticed when inoculated through bio-activated rock phosphate with A. awamori. In cowpea, more number of nodules was observed in plants inoculated through bio-activated rock phosphate with A. awamori. Inoculation through bio-activated rock phosphate with B. megaterium contained higher total P content and total biomass in cowpea. In ragi, total P content and total biomass were higher in plants inoculated through bioactivation of rock phosphate with A. awamori. The results indicate that inoculation of phosphorus solubilzing microbes through bio-activation of rock phosphate enhanced the phosphorus uptake and growth of cowpea and ragi. Keywords: Rock phosphate, Bacillus megaterium, Aspergillus awamori, phosphorus solubilzing microbes.
