Micronutrient deficiencies, especially iron (Fe) and zinc (Zn), pose a major challenge to sugarcane productivity in alkaline soils. This study comprehensively evaluated the application of a liquid bioinoculant containing Fe and Zn solubilizing microbes (FeZnSM) in combination with varying levels of micronutrient fertilizers. Field trials were conducted across three sugarcane factories in Maharashtra, India, employing a split plot design to assess effects on crop growth, yield, nutrient uptake, juice quality, soil fertility, and economic returns. Results demonstrated that integrating FeZnSM with 100% recommended Fe + Zn fertilizer produced the highest cane yield (123.81 t ha?¹) and CCS yield (17.95 t ha?¹), as well as substantial improvements in nutrient uptake, microbial populations, and soil micronutrient availability. Notably, combining FeZnSM with 50% of the recommended fertilizer dose delivered comparable yields and profitability, highlighting the potential to partially substitute chemical fertilizers with microbial bioinoculants. The findings underscore the value of integrating microbial and chemical micronutrient management for sustainable sugarcane cultivation in deficient soils.
