The highest canopy temperature was taken from T8 (22.76 °C) and minimum canopy temperature was taken from T13 (16.12 °C). T5 (52.42 mg) treatment was content maximum chlorophyll and T2 (44.21 mg) treatment was content minimum chlorophyll in marigold leaf. Highest Numbers of flowers was taken from T2 (44.13 days) and lowest T6 (32.80 days) treatment. Diameter of the flowers and ten flowers weight was maximum from T7 (7.25 cm), T7 (87.42 cm) treatment. Maximum Post-harvest life with distilled water condition and Post-harvest life with ambient condition was taken from T1 (6 days) and another also T1 (3.67 days). Maximum Post-harvest life with refrigerator was taken from T8 (13 days). Highest B: C was taken from T1 (3.19) treatment and lowest from T10 (1.7).
