dc.description.abstract | A greenhouse investigation was conducted to determine the effect the quantity of biochar application on VAM symbiosis in Leucaena leucocephala at two levels of nutrient amendment. There were 72 experimental units in this study arising from factorial combinations of 6 biochar levels, 2 nutrient levels and 2 VAM fungal inoculation levels with 3 replicates for each treatment. Application of either nutrients or biochar did not significantly influence the extent of VAM fungal colonization in roots of Leucaena. Phosphorus concentration shoot and root samples of plants grown in soil inoculated with Glomus aggregatum and supplied with 100 units of nutrients was highest at all levels of biochar amendment. In general, application of biochar did not influence plant phosphorus concentration irrespective of nutrient amendment. Inoculation of soil with Glomus aggregatum significantly increased biomass production by Leucaena. Marked reduction in dry weight of shoot and root as well as total biomass was noticed at biochar application level of 40 g/kg soil. The regression analysis of this data indicates that biochar application influences the phosphorus uptake and biomass production in Leucaena particularly when nutrients were applied. The results of this study illustrate the importance of optimizing the quantity of biochar as well as and nutrient application in order to derive maximum benefit from VAM symbiosis. | en_US |
