An experiment was conducted to know the effect of integrated nutrient management on growth and flowering of carnation (Dianthus caryophyllus L.). The experiment was conducted by applying different combinations of organic and inorganic nutrient sources. The plants were planted at the spacing of 20 cm x 15 cm and were laid out in Completely Randomized Block Design with three replications. Among the observed parameters, significantly maximum flower stalk length (75.45 cm), flower stalk girth (5.56 mm), number of flowers per plant (22.19), number of flowers per hectare (7395.93), marketable flowers (9.14%), water uptake (27.77 g), water loss (28.55 g) and vaselife (10.17 days) were recorded in plants receiving 75% recommended dose of nitrogen and phosphorus and 100% potassium + Azospirillum, brasilense + Bacillus megaterium + Glomus fasciculatum(VAM Fungi) + Trichoderma harzianum + vermicompost + panchagavya + jeevamrutha (T sub(7)) as compared to 100% RDF (T sub(1)). Hence treatment T sub(7) viz., 75% recommended dose of nitrogen and phosphorus and 100% potassium + Azospirillum brasilense+Bacillus me gaterium + Glomus fasciculatum(VAM Fungi) + Trichoderma harzianum + vermicompost + panchagavya +jeevamrutha was best for healthy growth and development.
