This review explores the impact of biofertilizers and nutrients on mustard (Brassica juncea) cultivation. Mustard, a vital oilseed crop in India, faces challenges such as low productivity and environmental concerns due to excessive chemical fertilizer usage. The paper emphasizes the significance of integrated nutrient management, combining chemical and organic sources, including biofertilizers. The study evaluates the effects on various growth parameters, yield attributes, economic aspects, soil nutrients, and microbial properties. Biofertilizers applications, particularly Azotobacter, PSB and SSB, show promising results in enhancing growth metrics, yield, and nutrient uptake. The judicious combination of chemical fertilizers and biofertilizers demonstrates the potential for improving mustard crop productivity while maintaining environmental sustainability.
