A study entitled “Effect of Pusa Hydrogel on Growth Performance, Flower Yield, and Quality Attributes of Marigold (cv. Calcutta Orange) under Different Irrigation Regimes” was carried out at the Department of Floriculture and Landscape Architecture, College of Horticulture, Bagalkot. The interaction between the irrigation and Pusa Hydrogel levels revealed maximum plant height of (80.11 cm) at 90 DAT in 80 per cent CPE irrigation interval with 5.25 kg per ha of hydrogel (I2H4). Higher number of primary branches per plant of 16.98 and 17.95 was reported in treatment combination of drip irrigation at 80 per cent CPE+5.25 kg per ha of hydrogel (I2H4) at 90 DAT and higher number of secondary branches per plant of 39.21 was reported in treatment combination drip irrigation at 80 per cent CPE+5.25 kg per ha of hydrogel (I2H4) at 90 DAT, respectively. Maximum individual flower weight (6.38 g), yield per plant (550.92 g) and yield per plot (18.66 kg) was recorded in plants irrigated with 80 per cent CPE with 5.25 kg/ha hydrogel (I2H4) and lowest yield was obtained in plants irrigated with 60 per cent CPE without any application of hydrogel (I3H5). Flower diameter and shelf life were found to be non-significant in the treatment combination of different levels of irrigation and hydrogel. Maximum B:C ratio (1.64) was obtained when irrigation was scheduled at 80 per cent CPE along with the application of 5.25 kg/ha hydrogel.
