Abstract

The present investigation was carried out at Model Floriculture Centre, G. B. Pant University of Agriculture and Technology, Pantnagar. The trial was laid in Randomized Block Design (RBD) with three replications and nine treatments. Among all the treatments plant height (63.53 cm), plant spread (55.57 cm), number of branches (5.93), number of leaves (189.33) and stem diameter (1.31 cm) were found maximum in plants treated with humic acid @ 3 mL L^-1 and 75% Recommended dose of fertilizers (RDF-60:120:120 NPK kg ha^-1) i.e., T4 after 150 days of application. T4 also exhibited maximum leaf area per plant (1023.75 cm²), early flower bud appearance (31.47 days), days taken for bud to bloom (12.47 days), 50 per cent flowering (49.33 days), maximum number of flowering shoots per plant per month (3.8), earliest days to harvest (44.40 days), maximum bud length (3.19 cm), bud diameter (1.85 cm), flower diameter (5.44 cm), number of petals per flower (46.73) andlongest flower longevity (5.73 days).Weight of single flower (3.97 g) and 100 flowers (398.87 g), number of flowers per plant per month (18.13), flower yield per plant per month (61.72 g), flower yield per plant per hectare (5693.17 Kg) and shelf life (29.20 hr) were also enhanced by T4 which also recorded highest benefit- cost ratio (2.62) whereas lowest value (0.73) was noticed in T9 (Arka microbial consortium + 50 % RDF) .
