Integrated Effect of Bio-Fertilizers, Organic and Inorganic Fertilizers on Flowering and Quality Attributes of Gladiolus (Gladiolus grandiflorus L.) cv. Nova Lux

Abstract

The study “Influence of bio-fertilizers on vegetative growth, flower quality and bulb yield of gladiolus (Gladiolus grandiflorus L.)”, field experiments conducted during 2020-21. Bulbous gladiolus is a very well-liked plant. Pliny the Elder (2379 AD) first used the term "gladiolus" to refer to the blade's sword-like form (Latin word gladiolus means sword). Gladiolus is a delicate perennial herbaceous plant that may be cultivated from seeds or bulbs. The roots of several older leaves that were developed during the previous growing season are covered with 4-6 dry scales or sheaths that cover the bulb. In addition to fixing nitrogen, phosphorus, and other nutrients from organic fertilisers and soil reserves, bio-fertilizers also help plants tolerate drought, boost plant health, and tolerate salt better [1] (Arora, 2013). A randomised block design with three replications was used to apply 14 different treatments, including the application of chemical fertilisers (Urea, SSP, and MOP), micronutrients (Zn and Fe), organic sources (FYM and Vermicompost), and bio-fertilizers (Azospirillum, Azotobacter, and PSB). Based upon the results recorded in the investigation it could be concluded that the treatment T10 (75% RDF + 25% Vermicompost + Azospirillum + PSB + Azotobacter), was found best treatment with reference to vegetative, nutritional, and productive parameters in gladiolus cv. Nova lux as compared to control and other treatments.
