Abstract


Field investigations were carried out to know the response integrated nutrient management on floral and cormal parameters in gladiolus (Gladiolus hybridus l.) cv. AMERICAN BEAUTY was carried out at precision farming development centre, Division of Horticulture, Gandhi Krishi Vignana Kendra, UAS, Bangalore during 2007-2008 and 2008-2009. The application of bio-fertilizer along with two levels of NPK with vermicompost have shown significant result in the treatments both in Kharif and Rabi seasons. The treatment T11 (52.31) and (48.49) took minimum days for spike emergence followed by T10, T9 and T8 treatments during Kharif and Rabi seasons, respectively. Less number of days taken for flower bud opening, more number of florets per spike, more durability of spike (days) increased spike length, spike girth, floret length, floret diameter, number of florets opening at a time and total number of spikes/plant, fresh weight of spike was found best in the treatment T11 the combination of VAM + Azospirillum + Trichoderma with 75% RDF and vermicompost had shown significant result followed by T10 the combination was 50% RDF + VAM + Azospirillum + Trichoderma with vermicompost 3 tons/ha, during Kharif and Rabi seasons, respectively. cormal parameters such as number of corms/plant, weight of corms, number of cormels, cormel weight, was maximum in T11 treatment followed by T10 in both Kharif and Rabi seasons
