Abstract: This experiment was conducted to investigate the effects of different concentrations of Salicylic acid and Sodium silicate as a foliar spray on greenhouse rose (Rosa hybrida var. Avalanche) to improve growth, flower quality and yield of rose. A total of 10 treatments T1= control, T2= Sodium silicate @ 1mM and Salicylic acid @ 1mM, T3 = Sodium silicate @ 1mM and Salicylic acid @ 3mM, T4 = Sodium silicate @ 1mM and Salicylic acid @ 5mM, T5 =Sodium silicate @ 3mM and Salicylic acid @ 1mM, T6 = Sodium silicate @ 3mM and Salicylic acid @ 3mM, T7 = Sodium silicate @ 3mM and Salicylic acid @ 5mM, T8 =Sodium silicate @ 5mM and Salicylic acid @ 1mM, T9 = Sodium silicate @ 5mM and Salicylic acid @ 3mM, T10 = Sodium silicate @ 5mM and Salicylic acid @ 5mM, were tested in randomised complete block design with three replications. All the treatments improve growth, flower quality and yield as compared to control treatment. The results of the study revealed that T10 significantly improved vegetative and flowering parameters of rose (Rosa hybrida). The parameters viz. maximum plant height (90.41cm), plant spread (45.44cm), number of basal shoots (3.64), diameter of basal shoots (1.05cm), number of compound leaves per flowering shoot (14.28). Minimum number of days to first flower bud appearance (105.33) and minimum number of days to colour break stage (20.57) was also recorded in T10 and flowering parameters viz. maximum flower bud diameter (1.40cm), neck girth (0.73cm), length of cut stems (74.47cm), girth of cut stems (0.77 cm), flower diameter (7.25cm), duration of flush (43.22days), number of cut stems plant-1 (6.63) and number of cut stems m-2 (30.00) maximum stem dry matter (8.15g) was recorded in T10. Maximum total fresh weight of cut stems harvested per plant (177.82g) and maximum vase life (11.41days) was recorded in T8.
