A field trail consisting three different planting depths (4.5, 5.5 and 6.5 cm) and three adequate spacing (10 X 10, 15 X 15 and 20 X 20 cm) was carried out at Research Farm, Flower Cafeteria Unit (FCU), Krishi Vigyan Kendra, Hastinapur, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (UP) during 2015–16 to 2016–17 to assess comparative performance of these different planting depth and spacing for improving yield and quality of tuberose. An important commercial cut flowers crop of India and waxy white flowers are highly valuable for preparation of garlands, bouquets and table or vase decoration. Cultivar double is considered most suitable for the purpose. The experiment was laid out in factorial Randomized Block Design (RBD) with three replications. Maximum number of sprouts per clump are 3.81 and 5.07, number of leaves per plant are 21.98 and 38.61 and length of longest leaf are 51.28 cm and 57.37 cm at 65 and 85 days after planting respectively were found under the treatment D2, where the bulbs were planted at the depth of 5.5 cm. Adequate wider spacing (20 x 20 cm) for cultivation of tuberose produced maximum number of sprouts per clump is 3.87 and 4.90 and highest number of leaves per plant are 22.88 and 39.87 and maximum height of plant is 42.08 and 50.87 at 65 and 85 days respectively after planting were found under the treatment S3, when the bulbs were planted at the depth of 5.5 cm. Adequate spacing had no significant effect on length of longest leaf and height of the tuberose plant. Therefore 5.5 cm depth of planting and 20 x 20 cm spacing may be recommended for better vegetative growth and yield of tuberose cultivar double under the agro-climatic condition of western plain region of UP.
