Soil health plays a pivotal role in sustaining agricultural productivity, particularly in the context of genetically modified crops such as Bt cotton. This study assesses soil fertility and physical parameters under irrigated and non-irrigated Bt cotton cultivation systems in North Maharashtra, India, spanning Jalgaon, Dhule, and Nandurbar districts. Using 210 soil samples collected over six years (2017-2023), key indicators including pH, electrical conductivity (EC), organic carbon (OC), and calcium carbonate (CaCO₃) were analyzed. Results reveal minimal variations between irrigated and non-irrigated soils but indicate low organic carbon and slightly alkaline soil conditions across both systems. The current research work emphasizes the need and important for integrated organic nutrient management to restore soil fertility under intensive Bt cotton cultivation practices. https://www.biotech-asia.org/vol23no1/study-of-soil-health-in-irrigated-and-non-irrigated-bt-cotton-in-north-maharashtra-region-of-india/ Bt cotton; Soil fertility; Irrigation; pH; Organic carbon; North Maharashtra; Soil health
