Wheat (Triticum aestivum L.) is one of the most significant crops and the backbone of food security worldwide. However, low wheat production remains a substantial concern in global agricultural systems. It can be attributed to several factors, including adverse climatic conditions, plant disease and poor soil quality. Recent efforts have explored bioinoculant applications as a promising approach to enhance wheat yield, trying to mitigate constraints essential for future wheat production and global food security. This study tested talc powder, wheat biochar, sugarcane bagasse biochar, and farmyard manure as carriers with two endophytic bacterial strains, Burkholderia phytofirmans PsJN and Bacillus spp. MN54 was applied to three wheat varieties (Ujala-16, Zincol-16, and Fathejang-16). The data was recorded at the seedling and maturity growth stages of plants. A pot experiment revealed significant improvements in plant growth following bioinoculant application compared to controls. Notably, the combination of sugarcane bagasse biochar with Bacillus sp. MN54 exhibited the most pronounced effects, promoting internodal length, spike length, tiller number per plant, grain yield per plant, and spikelets per spike. Additionally, talc powder with Bacillus sp. MN54 increased peduncle length, tiller number per plant, and spike length in Fathejang-16. These findings offer valuable insights into optimizing bioinoculant formulations for improved agricultural practices, adapting to climate change, and contributing to ensuring global food security.
小麦（Triticum aestivum L.）是世界上最重要的作物之一，也是全球粮食安全的支柱。然而，全球农业系统中仍然存在小麦产量低的问题。这可以归因于多种因素，包括不利的气候条件、植物病害和土壤质量差。最近的研究探索了生物接种剂的应用，作为提高小麦产量的一种有前途的方法，试图缓解未来小麦生产和全球粮食安全的关键限制。本研究测试了滑石粉、小麦生物炭、甘蔗渣生物炭和农家肥作为两种内生细菌菌株 Burkholderia phytofirmans PsJN 和 Bacillus spp. MN54 的载体，应用于三个小麦品种（Ujala-16、Zincol-16 和 Fathejang-16）。数据记录在植物的幼苗和成熟生长阶段。盆栽试验表明，与对照相比，生物接种剂的应用显著改善了植物的生长。值得注意的是，甘蔗渣生物炭与 Bacillus sp. MN54 的组合表现出最显著的效果，促进了节间长度、穗长、每株分蘖数、每株籽粒产量和每穗小穗数。此外，滑石粉与 Bacillus sp. MN54 增加了 Fathejang-16 的花梗长度、每株分蘖数和穗长。这些发现为优化生物接种剂配方以改善农业实践、适应气候变化和确保全球粮食安全提供了有价值的见解。
