A field study on ‘effects of integrated nutrient management on vegetative growth and flowering quality of gladiolus (Gladiolus hybridus Hort.) cv. American Beauty’ was carried out at College of Horticulture and Forestry, Jhalawar during 2016-17. It was found that cv. American Beauty with treatment the tallest plants (121.50 cm), maximum number of leaves per plant (9.03), the maximum leaf length (38.20 cm), earliest spike emergence (59.22 days), minimum number of days to floret opening (12.50 days), maximum number of florets per spike (17.53), maximum spike length (108.50 cm), maximum floret diameter (9.01 cm), maximum rachis length (39.03 cm) was found in T12 (RDF 75% + Azotobacter + PSB + Mycorrhiza). The maximum stem diameter (1.52 cm) and maximum spike girth (0.97 cm) was recorded in T10 (RDF 75% + PSB + Mycorrhiza). On the basis of foregoing summary, the results may be concluded as follow: The different bio-fertilizer treatments had significant influence on the vegetative growth, flowering and post-harvest of gladiolus in the present study. Application of bio fertilizer singly and in different combinations has significant effect on all the vegetative, floral and corms parameters. Therefore, among various bio fertilizers and their combinations, Azotobacter, PSB and Myccorhiza were found the best, followed by un-inoculated treatment show least value for these parameters during the seasons of experiment
