Abstract:
A pot experiment was conducted to study the effect of plant growth promoting rhizobacteria and growing media on growth parameters of tuberose (Polianthes tuberosa L.) cv. Prajwal at the botanical garden at CCS Haryana Agricultural University, Hisar. The experiment was laid out in a completely randomized design (CRD) with six Rhizobacteria(four strains of Bacillus viz., SYB101, RCA3, RCA7, HCA61 and two strains of Pseudomonas viz., CP109, and JMM16) and three growing media, i.e., sand, sand + FYM (2:1), sand + vermicompost (3:1). Among different rhizobacteria, Pseudomonas sp. CP109 and Bacillus sp. HCA 61 was found potent in enhancing the vegetative growth of tuberose. Among the growing media, sand followed by sand + FYM (2:1) and, in later stages, sand + vermicompost (3:1) were effective in increasing the vegetative growth of tuberose. Bacillus sp. HCA 61 and sand, Bacillus sp. HCA 61 and sand + FYM (2:1), and Pseudomonas sp. CP 109 and the sand + vermicompost (3:1) combination showed the best results with respect to the growth of tuberose.
