Abstract: An experiment was conducted at experimental field of Nalanda College of Horticulture, Bihar Agricultural university Sabour (Bhagalpur), Bihar to assess the influence of planting density and varieties on growth and flowering of African marigold (Tagetes erecta L.). The two varieties viz- Pusa Narangi and Pusa Basanti were planted with four spacing 50 x 50 cm, 50 x 40 cm, 50 x 30 cm, 40 x30 cm. and arranged in factorial randomized block design replicated thrice. The data were collected on account of plant height (cm), number of branches/plant, number of flower/plant, flower diameter (cm.), average flower weight (g) and flower yield per plant (kg), per plot (kg) and per hectare (q/ha). It was observed that all the growth and yield attributing traits were significantly influenced due to several treatment and recorded higher values with the wider spacing 50 x 50 cm and 50 x 40 cm., respectively, except, plant height, flower yield/plot and per hectare, which were maximum at closer spacing (40 x 30 cm). Between the varieties, Pusa Narangi recorded maximum number of flowers /plant, flower diameter, flower yield/plant, flower yield/plot and per hectare while, Pusa Basanti produced maximum plant height. The maximum flower yield (q/ha) was recorded with the Pusa Narangi planted at closer spacing 40 x 30 cm (S₄V₂).
