A field experiment was conducted at the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar to study the effect of integrated nutrient management on the flower yield of tuberose (Polianthes tuberosa L.) cv. Prajwal. The trial was laid out in randomized block design consisting of eleven treatments with three replications. The treatments include a combination of recommended doses of fertilizers along with the organic fertilizers such as the farm yard manure and vermicompost, foliar sprays of panchagavya, humic acid and effective microorganisms. Among the various treatments, the plants receiving a combination of 75 % RDF + Vermicompost @ 5 t ha-1 + Humic Acid @ 0.2 % (T9) was found to be best in all the yield attributes, viz., days to fifty per cent flowering (100.34 days), number of spikes per plant (4.75), spike length (57.36 cm), rachis length (20.94 cm), number of florets per spike (33.12), floret length (6.88 cm), floret diameter (4.50 cm), hundred florets weight (101.71 g), flower yield per plant (79.73 g plant-1), flower yield per plot (1.12 kg plot-1), flower yield per hectare (9.01 t ha-1) and number of bulbs per plant (5.01).
