Response of African Marigold (Tagetes erecta L.) to Integrated Nutrient Management

摘要

Response of African marigold (Tagetes erecta L.) cv. Giant African Double Orange to integrated nutrient management was studied at the Horticulture Research Fat, Department of Horticulture, IGKV, Raipur (Chhattisgarh) during the years 2007-08 and 2008-09 employing randomized block design having 10 treatments replicated thrice. Different integrated nutrient treatments were applied as basal and during vegetative stage of plant growth and development. Marigold cv. Giant African Double Orange when grown under the treatment 100% RDF (T-1) produced maximum fresh weight (265.78 g) and dry weight (55.49 g), while maximum chlorophyll content (52.12 SPAD) of leaves was recorded on 50% RDF+50% N FYM (T-7). Application of 50% RDF+50% N VC (T8) recorded maximum plant height (68.23 cm), number of branches (29.99), earliest 50% flowering (41.91 days), flower size (6.55 cm), number of flowers (22.23) and flower yield (27.00 kg/plot and 215.26 kg/ha).
