Studies were conducted to investigate the effect of integrated nutrient management on growth, yield and quality of Crossandra (Crossandra undulaefolia Salisb.) hybrid Arka Ambara. The study carried out at the Department of Horticulture, GKVK, UAS, and Bengaluru. Results recorded at 150 days after imposition of the treatments, the application of 100 per cent recommended dose of nitrogen, phosphorus and potassium + Azotobacter + PSB + KSB had significantly improved the growth, flowering and yield attributes. There was a significant increase in plant height (50.07cm), number of branches (16.20) and plant spread (2111cm²) and it was on par with 75 per cent RDF + Azotobacter + PSB + KSB (plant height 48.07cm, number of branches 15.50 and plant spread 2108cm²).Similarly in reference to flower and yield traits, the first spike initiation occurred as early as 85.03 days, the first flower harvest (93.03), number of flowers per spikes(28.96) and flower yield per ha (3.78 t) recorded were found to be significantly higher and it was found on par with 75 per cent RDF + Azotobacter + PSB + KSB (first spike initiation 89.33days, first flower harvest (97.33 days), number of flowers per spikes (30.67) and flower yield per ha (4.15 t).The soil analysis showed significantly increased levels of available nitrogen, phosphorus and potassium content as recorded at the end of experiment. It was also observed that beneficial microbial population of bacteria, fungi and Actinomyces were higher at the end of experiment.
