Abstract
Background and objectives: Telangana district is renowned for its prominence in cotton production, a crop vital to the livelihoods of local farmers. For years, synthetic fertilizers have been relied upon to bolster yields, but escalating costs have shifted focus towards biofertilizers as a cost-effective and sustainable alternative.
Materials and methods: A microbial consortium comprising Rhizobium sp. PKS, Bacillus sp. PU-7, and Funneliformis mosseae AMF was employed. Microbial identification was performed using 16S rRNA gene sequencing. Biochemical evaluations of consortium-inoculated plants included measurements of protein, sugar, proline, and chlorophyll levels, along with IAA quantification.
Results: A consortium of Bacillus sp. PU-7, Rhizobium sp. Pks [NCBI OK663003, NCMR-MCC4960], and Funneliformis mosseae enhanced Mahyco cultivar growth. Treatment increased plant height, fresh and dry weight, and improved biochemical profiles (reduced proline, elevated IAA, protein, chlorophyll, and sugars). Soil field trials were undertaken in four cotton-producing regions of Mahabubnagar region confirmed for efficacy, with deep black soil promoting phytohormone synthesis (IAA-917.66 ± 2.51) and light black soil (IAA-802 ± 2) enhancing plant growth.
Conclusion: Given these outcomes, the application of the tested bioinoculants and AMF spores is suggested as an effective strategy to enhance cotton development and yield in the soils of Mahabubnagar, potentially revolutionizing the district's agricultural practices.
期刊介绍：
The Iranian Journal of Microbiology (IJM) is an international, multi-disciplinary, peer-reviewed journal that provides rapid publication of the most advanced scientific research in the areas of basic and applied research on bacteria and other micro-organisms, including bacteria, viruses, yeasts, fungi, microalgae, and protozoa concerning the development of tools for diagnosis and disease control, epidemiology, antimicrobial agents, clinical microbiology, immunology, Genetics, Genomics and Molecular Biology. Contributions may be in the form of original research papers, review articles, short communications, case reports, technical reports, and letters to the Editor. Research findings must be novel and the original data must be available for review by the Editors, if necessary. Studies that are preliminary, of weak originality or merely descriptive as well as negative results are not appropriate for the journal. Papers considered for publication must be unpublished work (except in an abstract form) that is not under consideration for publication anywhere else, and all co-authors should have agreed to the submission. Manuscripts should be written in English.
