Effect of time and depth of planting on growth, flowering and yield of tuberose cv. Single

Field experiment was carried out to study the suitable planting dates and depths for tuberose under Manipur conditions. Early (20th April) and shallow planting (4 cm) recorded significantly the maximum values for vegetative growth, floral and bulb parameters. Among the treatment combinations, April 20th at 4 cm (P1D1) significantly improved the spike length (91.2 cm), rachis length (17.73 cm) and spikes yield per hectare (3, 14, 000 No.), while, P1D3 resulted in maximum spike longetivity (18.13 days), maximum number of bulbs per clump (16.07), maximum bulb weight per clump (16.08 g) and maximum diameter of the largest bulb (3.68 cm). However, maximum number of florets per spike (28.07) was obtained in P1D2.
