Abstracts |
The effects of N rate (25, 50, 75 or 100 kg/ha) and vesicular arbuscular mycorrhiza (VAM; Glomus mosseae and Azospirillum lipoferum, singly or in combination) on nutrient uptake by onion (cv. B-780) were studied in India during kharif 2000. G. mosseae was applied by soil inoculation (680-700 spores/50 ml of soil), whereas A. lipoferum was applied by seedling dip method (200 g peat-based culture/litre of solution). The effect of N rate and VAM inoculation on nutrient uptake was significant, but the effect of the interaction between treatments was not significant. Among the N rates, 25 and 50 kg/ha resulted in the greatest root colonization (74.90 and 76.49%). N at 75 and 100 kg/ha recorded the greatest N uptake at 60 (121.25 and 125.71 kg/ha) and 90 days after transplanting or DAT (190.65 and 167.59 kg/ha), and P uptake at 60 (25.01 and 26.33 kg/ha) and 90 DAT (53.41 and 55.50 kg/ha). Fe, Zn and Mn uptake did not significantly vary with the N rate. Among the inoculation treatments, G. mosseae + A. lipoferum recorded the greatest root colonization (86.58%), number of chlamydospores (295.47/50 ml of soil), N uptake at 60 (133.11 kg/ha) and 90 DAT (295.47 kg/ha), P uptake at 60 (27.02 kg/ha) and 90 DAT (59.73 kg/ha), and Fe (470.03 kg/ha), Zn (428.89 kg/ha) and Mn (311.55 kg/ha) uptake at 90 DAT.. |
