A field experiment was carried out at the Central Research Farm, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal representing the lower Gangetic plain of India during the winter seasons of 2011-‘12, 2012-‘13 and 2013-‘14 on integrated nutrient management of inorganic fertilizers and organic manure on growth, floral attributes and yield of Gladiolus hybridus. Maximum flower yield (9731 kg/ha), number of corms per plant (3.5), growth and quality parameters was recorded with integration of 50% recommended dose of chemical fertilizers (RDF) with vermicompost @ 2.5 ton/ha. The build-up of available N, P and K in soil and consequent higher plant leaf nutrients was also detected with 50% RDF + vermicompost @ 2.5 ton/ha. In contrast, minimum growth, quality parameters, less number of corms per plant and flower yield, lower plant leaf nutrients and higher depletion of available N, P and K in soil were observed under unfertilized control treatment. Thus the conjunctive use of 50% RDF with vermicompost @ 2.5 ton/ha may be recommended for improving the quality and productivity of G. hybridus and improvement of available N, P and K status in soil.
