Abstract:
An experiment was conducted at horticulture farm, RRS., Agwanpur, Saharsa to standardize the time of planting and nitrogen requirement of tuberose cv. “Calcutta double” in a factorial randomized block design with three replications. In this experiment 3 dates of planting (15th February, 15th March, 15th April) and 4 levels of nitrogen (0, 150, 200, 250 kg/ha) were applied. The results indicated that 15th April planting date and application of nitrogen 250 kg/ha recorded maximum vegetative growth, yield and floral characters. However a dose of 250 kg/ha was found optimum for better growth and flowering in tube rose cv. “Colcatta Double”.
