Progressive Agriculture

The present investigation was carried out at Model Floriculture Centre during 2007–08 and 2008–09 to find out the response of organics and bio-inoculants on vegetative characters, flower quality, corms and cormels yield of gladiolus (Gladiolus hydrida) cv. White Prosperity. The experiment was laid out in randomized block design with three replications. The treatments were comprised of organics and bio-inoculants alone (vermicompost, poultry manure, Trichoderma sp., Pseudo-monas sp. and AMF) and their combinations along with this Microbial count of the soil was taken by serial dilution method. The treatment combination of vermicompost + AMF (T9) recorded the significant highest value of plant height (57.64 cm) and highest number of leaves (7.03) per plant. AMF (T9) exhibited maximum number of days (5.29) taken by basal floret from showing colour to fully opened stage and total number of florets per spike (12.57) recorded in Pseudomonas (T₄). Poultry manure + Trichoderma sp. (T₁₀) significantly influenced the spike length (78.06cm). Maximum spike weight (62.79g) was observed in Pseudomonas (T₄). Corm size (7.69 cm) and corm weight (58.01 g) were found maximum in the treatment combination of poultry manure + Pseudomonas (T₁₁). Vermicompost (T₁) had improved the florets size (10.01 cm) and longest vase life (11.94 days) of cut spike was observed in combination of vermicompost + poultry manure " (T₆). This was all might be due to the positive effect of organics and micro-organism.
