The research was conducted to assess the impact of various organic and inorganic fertilizers on the growth and yield of Marigold (Tagetes erecta L.) var. Calcuttia Single using a randomized complete block design with eight treatments including vermicompost, farmyard manure, poultry manure, charcoal, NPK fertilizer, and their combinations in triplicates. Measurements of vegetative and reproductive parameters were recorded at 35, 55 and 85 DAT. Results revealed that compared to the control, poultry manure and vermicompost, singly or combined with NPK, significantly enhanced both vegetative and reproductive traits. Poultry manure resulted in the tallest plants (126.21 cm), the highest number of branches (29.93), and the largest flowers (14.11 cm diameter), with the earliest flowering (51.33 days). Vermicompost showed effectiveness in plant height (117.37 cm), number of branches (28.80), plant spread (81.43 cm) and flower number (40.47) The control plot exhibited the least effectiveness in all parameters. These findings highlight the significant role of organic fertilizers in enhancing the growth and yield of Marigold (Tagetes erecta L.) var. Calcuttia Single.
