Impact of Integrated Nutrient Management (INM) on Flowering and Corm Production in Gladiolus

Type: article
Abstract: A field experiment was carried out to evaluate the impact of Integrated Nutrient Management (INM) on flowering and corm production of gladiolus during rabi season of 2010-11 at OUAT Bhubaneswar. The result of the study revealed that INM practices involving inorganic fertilizer, Vermicompost and Bio-fertilizer (Azospirillum and Phosphate solubilising bacteria) in different combinations had no significant influence on sprouting of corms. However, it had significant influence on flowering and corm production in gladiolus. Application of 75% RDF(100:50:60 Kg NPK/ha) in combination with Vermicompost and Biofertilizer increased spike length (70.53 cm), rachis length (55.55 cm), number of florets per spike (13.12), and number of florets remained open at time (7.46) as compared to other treatments. As far as corm characters were concerned, combined application of 75% RDF, Vermicompost and Biofertilizers resulted in maximum weight (75.66 g) and diameter (6.59 cm) of daughter corm as well as number (58.36) and weight (32.43 g) of cormels per plant.
