SYNERGISTIC EFFECT OF AM FUNGUS AND RHIZOBIUM INOCULATION ON ARACHIS HYPOGEAE L. IN UNSTERILE SOIL
lessThan i greaterThan Arachis hypogeae lessThan /i greaterThan L lessThan i greaterThan . lessThan /i greaterThan groundnut is a second largest source of edible vegetable oil. Medicinally the oil is used as a laxative and emollient. lessThan i greaterThan Arachis hypogeae lessThan /i greaterThan L lessThan i greaterThan . lessThan /i greaterThan seedlings were grown in earthen pots containing unsterilized soil inoculated with lessThan i greaterThan Glomus fasiculatum lessThan /i greaterThan , lessThan i greaterThan Rhizobium lessThan /i greaterThan or a combination of symbionts. After 90 days growth, plant height, dry weight, root dry weight,mycorrhizal colonization, spore number, percent of yield, nitrogen and phosphorous content were quantified. Plant with either a combination of mycorrhizal fungi and R lessThan i greaterThan hizobium lessThan /i greaterThan grew taller and produced higher dry matter of root and shoot than infected with lessThan i greaterThan Rhizobium lessThan /i greaterThan species alone or control plants. The presence of lessThan i greaterThan Rhizobium lessThan /i greaterThan increased the nitrogen content of above the ground. Foliage number increased with inoculation of mycorrhizal fungi and phosphorus content was increased. In the present study mycorrhizal fungi and lessThan i greaterThan Rhizobium lessThan /i greaterThan were found to be synergistic with respect to nitrogen fixation and percent of root colonization.
