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.
A microbial consortium comprising sp. PKS, sp. PU-7, and 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.
A consortium of sp. PU-7, sp. Pks [NCBI OK663003, NCMR-MCC4960], and 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.
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.
特伦甘纳地区以其在棉花生产方面的突出地位而闻名，棉花是当地农民生计的重要作物。多年来，一直依赖合成肥料来提高产量，但成本不断上升已使人们将重点转向生物肥料，将其作为一种经济高效且可持续的替代方案。
使用了由sp. PKS、sp. PU - 7和AMF组成的微生物联合体。通过16S rRNA基因测序进行微生物鉴定。对接种联合体的植物进行的生化评估包括蛋白质、糖、脯氨酸和叶绿素水平的测量，以及吲哚 - 3 - 乙酸（IAA）定量分析。
由sp. PU - 7、sp. Pks [NCBI OK663003, NCMR - MCC4960]和AMF组成的联合体促进了Mahyco品种的生长。处理增加了株高、鲜重和干重，并改善了生化指标（脯氨酸减少、IAA、蛋白质、叶绿素和糖含量升高）。在马哈布卜纳加尔地区的四个棉花种植区进行的土壤田间试验证实了其有效性，其中深黑色土壤促进了植物激素合成（IAA - 917.66 ± 2.51），浅黑色土壤（IAA - 802 ± 2）促进了植物生长。
鉴于这些结果，建议应用经测试的生物接种剂和AMF孢子作为提高马哈布卜纳加尔土壤中棉花生长和产量的有效策略，这可能会彻底改变该地区的农业实践。
