Effect of different levels of fertigation and growth regulators on growth, yield and quality of rose cultivars under polyhouse condition

The growth, yield and quality parameters like plant height (67.18 cm & 68.28 cm), number of primary branches per plant (4.93 & 5.32), days taken for emergence of first flower bud (33.07 days & 32.93 days), number of cut flowers per plant (14.21 & 14.01), shoot girth (0.72 cm & 1.00 cm), diameter of flower bud (3.18 cm & 3.13 cm), length of flower bud (3.86 cm & 3.51 cm), length of cut flower stalk (59.76 cm & 55.60 cm),vase life (8.14 days) and B:C ratio (1:1.65) were significantly superior in the treatment F2 (120 % fertigation) in the seasons 1 and 2 respectively.
