| dc.description.abstract | Response of onion {Allium cepa L.) cv. N-53 to the inoculation of efficient vesicular arbuscular mycorrhizal (VAM) fungi, Acaulospora laevis and Gigaspora margarita at different P levels [0,50, 75 and 100 per cent recommended dose (PRD) (75 kg ha'^)] was studied under glass house condition. The percent mycorhizal root colonization, spore count and mycorhizal inoculation effect increased in the plants inoculated with VAM fungi with addition of P up to 75 PRD (37.5 kg ha-1), while the population of free living N2 fixers and P-solubilizers increased with addition of P upto 100 PRD of P (50 kg ha-1). Among the VAM Fungi, plants inoculated with Gigaspora magarita had significantly highest per cent mycorrhizal root colonization, spore count, mycorrhizal inoculation effect, population of free living N2 fixers and Psolubilizers in the rhizosphere soil as compared to plants inoculated with Acauiospora iaevis and uninoculated control plants. The shoot P concentration, alkaline phosphatase activity, total soluble solids, ascorbic acid content, plant height, number of leaves, plant dry weight, fresh bulb weight, bulb diameter, bulb length and neck thickness increased with increase in P level upto 100 PRD. The fresh bulb weight, plant height and plant dry matter of onion was maximum in plants inoculated with Gigaspora margarita and given 100 PRD of P. However it did not differ significantly from plants inoculated with Gigaspora margarita and given 75 PRD of P, suggesting a net saving of 25 PRD of P with efficient VAM fungi. | en_US |
