The studies on the effect of different irrigation methods and mulching on growth, yield and quality of gladiolus revealed that raised bed with drip irrigation and mulching was found effective resulting in maximum growth and quality parameters, minimum weed intensity and conserving soil moisture throughout the growth period in gladiolus. The efficacy of biofertilizers for nutrient management revealed that application of Pseudomonas strain (WPS73) with 75% RDF followed by Azotobacter chroococcum (Mac27) with 75% RDF was beneficial for growth and quality of gladiolus. Incompatibility was observed in coinoculation of Azotobacter chroococcum (Mac27) and Pseudomonas strain (WPS73), which resulted in complete mortality of plants when applied in combination. The study on dynamics of biofertilizers in combating biotic stress revealed that four strains HWM13, HCS2 from Pseudomonas species and RSD8, NNY19 from Bacillus species showed antifungal activity under plate conditions. Rhizobacterial strain HCS2 of Pseudomonas species showed its positive effect in suppressing Fusarium wilt disease caused by fungal pathogen Fusarium oxysporum f. sp. gladioli in gladiolus under pot conditions.enIrrigation, Bacteria, Planting, Cultivation, Gladiolus, Biological development, Developmental stages, Diseases, Biofertilizers, AzotobacterThesis
