Description ABSTRACT
The investigation entitled “Effect of nitrogen and phosphorus on growth and flowering in tuberose (Polianthes tuberosa L.) cv. Double” was conducted at experimental farm of the Department of Floriculture and Landscaping, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2011. The experiment was laid out in factorial randomized block design with sixteen treatments replicated thrice. Among the treatments, T11 (200 kg N/ha + 100 kg P2O5/ha) was recorded maximum per cent sprouting of bulbs (100%), plant height (48.38 cm), number of leaves per plant (47.59), number of days taken for spike emergence (98.81 days), number of days taken for basal florets opening (119.10 days), spike length (80.88 cm), number of florets per spike (30.48), rachis length (29.95 cm), fresh weight of spike (70.89 g), fresh weight of 100 florets (179.71 g), floret diameter (3.51 cm), number of flowering stems per plant (2.23), number of bulbs produced per plant (16.68), weight of bulbs per plant (276.03 g), available phosphorus (66.39 kg/ha), available potassium (192.52 kg/ha), minimum cost of production (Rs. 91.71/m2), maximum net returns (Rs. 246.53/m2) and benefit cost ratio (2.69). However, minimum number of days taken for sprouting of bulbs (12.73 days) and maximum amount of available nitrogen (462.71 kg/ha) were recorded in N3P3 (300 kg N/ha + 150 kg P2O5/ha). The maximum vase life (10.05 days) was recorded in N0P3 which was closely followed by N0P2, N0P1 treatments
