There were four different levels of fertigation N @ (60 kg/ha, 80 kg/ha, 100 kg/ha and 120 kg/ha) were applied to chrysanthemum varietiy namely ‘Ratlam Selection’ through drip irrigation along with three different spacing levels i.e., 40×30 cm, 40×40 cm and 40×60 cm. Split Plot Design (SPD) was the statistical method employed, and the trial was repeated three times.

Data on growth, flowering and yield factors were collected and statistically analysed. The data observed on growth and floral attributes, i.e., number of branches (7.80),plant spread (46.70), flower weight (3.22 gm), maximum chlorophyll content least days to flower bud initiation (82.92 days), flower weight (3.22 gm) and highest chlorophyll content (58.57 spad value) was recorded with the application of N @ 120 kg/ha^-1 with planting distance of 40×60 cm and the maximum flower diameter (7.71 cm) and number of flowers per plant (138.67) were recorded higher with the application of N @ 100 kg/ha^-1 with planting distance of 40×60 cm. Yield attributes such as total flowers weight per unit area (m²), number of flowers per unit area (m²), were recorded best with treatment N @ 100 kg/ha with plant spacing 40×60 cm. The research's findings indicate that the best fertigation for producing high-quality loose chrysanthemum flowers, with a spacing of 40×60 cm, and fertigation N @ 100 kg/ha.”
