Field experiment was undertaken during 2014-2015 to find out the influence of different organic inputs and growth regulators on yield and quality of french marigold (Tagetus patula L.) cv. Sindhamani, in a farmer’s field at Sivapuri near Annamalainagar, Tamil Nadu. Various organic inputs and growth regulators including panchakavya 2 per cent, vermiwash 1: 5 dilution, humic acid 0.02 per cent, gibberellic acid 300 ppm, triacontanol 250 ppm were applied and yield and quality characters were studied at different stages of crop growth. The treatment with gibberellic acid @ 300 ppm + panchakavya @ 3 per cent recorded maximum number of flowers per plant, flower yield per plant, single and ten flower weight, flower diameter and number of petals per flower compared to other treatments. The gibberellic acid @ 300 ppm + vermiwash 1:5 dilution were considered as the next best level in terms of, yield characters of the french marigold.
