Abstract:

The performance and water use efficiency (WUE) of Chrysanthemum var. Marigold was evaluated under two moisture regimes, i.e., 100 % FC and 70 % FC imposed and maintained using gravimetric method. At 100 % FC, the plant height (30.33 cm), average plant spread (38.21 cm), number of  primary branches/plant (5.67) and secondary branches/plant (4.67), number of leaves/plant (71.67), number of flowers/plant (136.75), average weight of individual flowers (7.21g), RWC (94.29%), root: shoot ratio (0.42), total fresh bio mass (153.09 g), flower yield (881.67 g / plant) and shelf life of 7.58 days were significantly higher compared to plants grown under 70% FC. The gas exchange characteristics i.e. photosynthetic rate, stomatal conductance and transpiration rate were also significantly higher in plants grown at 100 % field capacity compared to 70 % field capacity treatment. However, the water use efficiency (WUE) of chrysanthemum was higher at 70% FC (39.82 g/litter) compared to 100 % FC (22.38 g/litter). The results of the study showed that, the plants maintained under 100 % FC produced a greater number of flowers with enhanced shelf life compared to plants grown under 70 % FC. Hence it is suggesting that Chrysanthemum var. Marigold performed better in higher moisture regime than 70 % FC level.
