Influence of organic inputs and growth regulators on growth, of french marigold

Field experiment was undertaken to find out the influence of different orgaftfc inputs and growth regulators on growth, yield and quality of French marigold (Tagetes patula L.) cv. Sindhamani, in a farmer’s field at Sivapuri near Annamalainagar, Tamil Nadu. The experiment was laid out in randomized block design with three replications. Various organic inputs and growth regulators including panchagavya 3%, vermiwash 1:5 dilution, humic acid 0.02%, gibberellic acid 300ppm, triacontanol at 250 ppm were applied. The growth, yield and quality characters were studied at different stages of crop growth. The study revealed that the growth characters expressed as plant height, number of laterals, number of leaves and leaf area were siginificantly higher by the application of Gibberellic acid @ 300 ppm + Panchagavya @ 3%. The hlorophyll content was also enhanced in this treatment.
