Abstract :

A field experiment on the influence of polyhouse cultivation on floral characters of African marigold (Tagetes erecta L.) cultivars was carried out during July 2015 – November 2015, at the Department of Pomology and Floriculture, College of Horticulture, KAU, Vellanikkara, Kerala. Eight African marigold (Tagetes erecta L.) cultivars were evaluated for their performance with regard to various floral characters, under open field and polyhouse (rain shelter) conditions during the rainy season. A significant influence of growing conditions was observed with respect to days to 50 per cent flowering, number of flowers/plant, marketable flower yield and shelf life of flowers of the cultivars was noticed. But the growing condition had no significant influence on flower length, pedicel length and seed yield/flower of the cultivars. Highest number of flowers/plant (76.83) and marketable flower yield (665.02 g/plant) were recorded in cultivars Local Orange and Orange Giant respectively, grown under rain shelter condition. The cultivars Sonata Orange and Sonata Yellow grown under rain shelter condition recorded maximum shelf life of flowers (4.79 days). Cultivation of African marigold under polyhouse (rain shelter) condition was found better than open field cultivation during the rainy season in Kerala.
