The study was aimed to assess the effect of different bio-fertilizer on growth and flower quality characteristics of Gladiolus (Gladiolus grandiflorus L.)An experiment with complete randomized block design (RCBD) having five biofertilizer treatments containing N-fixer bacteria (Azotobacter, Azospirillum), Rhizobium and P solubilizing bacteria with control and three replications was completed under green house conditions. The present results have shown that all the vegetative and reproductive growth accomplished successfully by application of biofertilizers. However, the treatment containg Azospirillum (T4) gained highest values in terms of plant height, florets spike-1, Spike length, Florets fresh weight and earlier sprouting than rest of the treatments. The role of biofertilizers in cormels production and nutrient uptake, T4 had also superiority with more cormels plant-1 and played leading role in nutrient (NPK) absorption than the control one. So, in this experiment Biofertilizer has been identified as an alternative to chemical fertilizer in order to increase soil fertility and crop production in sustainable farming.
