| dc.description.abstract | A greenhouse investigation was conducted to determine the effect of acidulation and bioactivation of north carolina rock phosphate (NCRP) and inoculation of soil with VAM fungus on phosphorus uptake and growth of maize and pigeon pea in an alfisol. This investigation consisted of 24 treatments resulting from factorial combination of two plant species, two levels of Glomus aggregatum inoculation and six levels of phosphorus amendment. Based on titrable acidity data the acidification potential of Penicillium sp. was found to be higher than that of Bacillus sp. The extent of mycorrhizal fungal colonization in roots of pigeon pea was higher than that maize. Inoculation of soil with VA mycorrhizal fungus caused significant increase in total phosphorus uptake and biomass of pigeon pea as well as maize. The extent of increase in total phosphorus uptake and biomass due to mycorrhizal inoculation in pigeon pea was most higher than that of maize. The phosphorus uptake efficiency of maize was lower than that of pigeon pea. Mycorrhizal colonization significantly reduced phosphorus utilization efficiency of both plant species. The results of this study suggest that application NCRP bio-acidulated with Bacillus sp. and Penicillium sp. increases phosphorus uptake of maize and pigeon pea and inoculation of soil with VA mycorrhizal fungus augments that effect. | en_US |
