Abstract:
The field trials were conducted to study the effect of different doses of nitrogen, phosphorus and spacing on vase life 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 vase life characters were significantly influenced by effect of nitrogen, phosphorus and spacing. The T-18 resulted best in respect of opening of 2^nd pair of flowers (15.74 days), opening of 3^rd pair of flowers (17.83 days), Length of 1^st, 2^nd and 3^rd pair of flowers ( 13.17 cm), diameter of 1^st, 2^nd and 3^rd pair of flowers (0.54 cm), no. of open florets/spike (34.40), percentage of open florets/spike (99.13), water uptake in vase (33.68 ml) and vase life of spike (19.43 days) while minimum values reported with T-1 @ 24.89 days, 25.88 days, 11.39 cm, 0.36 cm, 19.74 numbers, 97.05 %, 19.89 ml and 13.80 days respectively.
