The present investigation entitled “Impact of integrated nutrient management on post harvest and corm characters of gladiolus cv. Novalux” was carried out at Model Floriculture Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, during 2010–11 and 2011–12. The experiment was conducted in simple Randomized Block Design (RBD) with three replications and twenty five treatments consisting of, biofertilizers (Azotobacter, PSB and KSB), different levels of inorganic fertilizers, and their combinations. Application of 3/4ᵗʰ N, P and K+ Azotobacter + PSB + KSB (T₂₄) was found most effective in weight of corm/plant, size of corm, water uptake, available N and K content in soil. Maximum number of florets opened per spike, available P content in soil were recorded with application of 1/2 N, P and K + Azotobacter + PSB + KSB (T₂₅). However, maximum fresh and dry weight of spike was found with application of 3/4ᵗʰ N, P and K + Azotobacter + KSB (T₁₈). Treatment 3/4ᵗʰ N, P and K+ PSB + KSB (T₂₁) resulted in maximum vase life. Whereas, 3/4ᵗʰ N, P and K + Azotobacter + PSB (T₁₅) resulted in to maximum number of corms and cormels/plant.
