The experiment was conducted to find out the influence of Integrated Nutrient Management on growth, yield and quality of Gladiolus cv. Novalux during October 2011 to April 2012 at Horticultural Research Station, Tamil Nadu Agricultural University, Yercaud. The experiment consists of 16 treatments with replicated twice and it includes application of organic, inorganic and biofertilisers. The results of the experiment revealed that the number of days taken for spike emergence was earliest in the treatment T12 [75% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] - 92.10 days than the control. The number of days taken for first floret opening (104.20) was earliest in the treatment T12 [75% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant) ] than the control T17 (125.47 d).Significant effect on spike length was noticed by the application of T16 [50% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant)+ PSB (2 g/plant)] - 83.43 cm than the control (71.10 cm).Rachis length (53.60 cm) observed was higher in the application T16 [50% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] than the control (40.63 cm).The highest diameter of the floret (10.3 cm) was noticed with the application of T12 [75% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] than the control (7.18 cm).Lengthier floret (8.56 cm) was also noticed with the application of T12 [75% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)].Spike weight (61.27 g) observed was higher in the application T16 [50% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] than the control (38.13 g).The application of T16 [50% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] produced more number of florets per spike (18.13).Marketable spikes per plant (1.79 No.) and flower yield per meter square (19.50 No.) was noticed higher in T16 [50% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] than the control. The application of T16 [50% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] had significantly influenced on number of florets remain open at a time (4.67) and also on vase life (6.40 d) of flower. From the results obtained in this experiment, it could be concluded that application of T16 [50% RDF + FYM (2 kg/m2) + Vermicompost (300 g/m2) + Azospirillum (2 g/plant) + PSB (2 g/plant)] will significantly improve the growth, yield and quality parameters which ultimately result in increased return in Gladiolus cv. Novalux under Shervaroy condition.
