Effect of Spacing, Nitrogen and Phosphorus on Growth and Flowering Characters of Tuberose under Eastern Part of Uttar Pradesh Conditions

Abstract

A field experiment was conducted to study the effect of different Nitrogen, phosphorus and spacing doses on the growth and flowering characters of tuberose cv. Hyderabad double at Krishi Vigyan Kendra- 1, Azamgarh, during 2019-20 and 2020-21. The treatments consisted 4 levels of Nitrogen (100, 200, 300 and 400 kg/ha-1), 3 levels of phosphorus (100,150, and 200 kg/ha-1 ), respectively and 3 spacing’s: 30 x 20 cm, 30 x 30 cm, and 30 x 40 cm were evaluated in factorial randomized block design replicated thrice. The results revealed that the growth and quality characteristics of tuberose were increased significantly. The best result reg. maximum plant height (43.77 cm), number of leaves/plant (27.25), length of leaves (60.97 cm), width of leaves (2.60 cm), days for spike emergence (109.77 days) days to flowering (118.68 days), spike length (88.80 cm), rachis length ( 35.71 cm), Florets/spike (34.99), spike /clump ( 3.17), flowering duration ( 31.64 days) and flower’s yield ( 4.18 lakh/ha) were reported with S2N2P2 (30 x 30 cm, 200 kg/ha, 150 kg/ha).
