Notes:
Summary Nitrogenase activity in the rhizosphere soil of intermediate deep water rice was investigated employing gas chromatographic acetylene reduction assay. A raise in the plant density decreased the rhizosphere nitrogenase. Moreover, nitrogen fixation in the rhizosphere soil varied among the three rice varieties under intermediate deep water situations. Results indicate that nitrogen fixation is affected by plant density and the rice variety.
