Sunflower (Helianthus annuus L.) is a globally significant crop for vegetable oil production, with its cultivation methods playing pivotal role in agricultural sustainability. Our aim was to explore the potential of winter cover crops (WCC) preserve soil health between crops, fostering diverse rhizospheric microbial populations after two years under field conditions. Specifically, this study investigates how WCC inclusion rotation and suppression (chemical or rolling) used prior cash impact sunflower growth rhizosphere bacterial fungal communities, determined through Illumina sequencing 16S rRNA genes internal transcribed spacer (ITS) amplicons. results showed increase plant height, stem diameter, head dry weight plots where suppressed glyphosate when compared those standard chemical fallow. In addition, we observed that community plants cultivated underwent had greater Pielou’s evenness index than maintained as The Chao1 increased included received phosphorus fertilization. choice method—mechanical chemical—showed differential impact. While rolling adversely affects growth, certain reproductive stage variables perform better chemically-suppressed plots. However, associated decline bacteria beneficial while mechanical methods, such rolling, enhance their presence. Additionally, our evidenced positive correlation diversity parameters (height number leaves, weight). Transitioning from fallow offers benefits but requires exploring herbicide reduction strategies, including control compatible species, balanced sustainable approach maintain health.
