Different growing conditions with temperature and sunlight variation could vary in flower growth and quality of marigold. Plant growth and flowering characteristics are compared in three different conditions viz. plastic house, shade house and open field. Three varieties of marigold viz. Marvel Yellow, Marvel Orange and Marvel Garland with similar cultural practices were grown and observed. Each variety with 6 replications was grown in three different growing conditions. Plant height, leaves formation, length of leaves, number of days to flower, number of flowers per plant and post harvest analysis were recorded. Plant growth characteristics followed by flowering behavior were found significantly better in plants grown under plastic house. During post harvest experiment Marvel Garland variety grown under plastic house with wet post harvest treatment was found significantly better compared to other conditions.
