Abstract: The present investigation entitled “response of Marigold (Tagetes erecta L.) cv. Double Orange to liquid formulations of effective microbial consortia with graded levels of NPK on flower yield and quality traits” was carried out at Department of Horticulture, College of Agriculture, Shivamogga, Karnataka, during 2014-15. The experiment was laid out in Randomized Block Design with 15 treatments replicated thrice. Studies showed significant effect on flower weight (8.37 g), flower diameter (8.04 cm), number of petals per flower (323.12), number of flowers per plant (91.34), flower yield per plant (572.86 g), flower yield per plot (20.62 kg) and flower yield per hectare (12.70 t) was recorded in the treatment which received 75 % RDF + Azotobacter + Bacillus megaterium + Frateuria aurentia (T14). Petal meal yield per kilogram of fresh flower (90.84 g), petal meal yield per hectare (1156.40 kg), xanthophyll content (42.21 g) per kilogram of petal meal and xanthophyll yield per hectare (48.61 kg) were also recorded maximum with the same treatment i.e., T14 (75 % RDF + Azotobacter + Bacillus megaterium + Frateuria aurentia) compared to cent per cent RDF.
