Integrated nutrient management (INM) influences carrot productivity through simultaneous effects on growth, yield, quality, and economic returns, making single-trait evaluation inadequate. The present study aimed to develop an Integrated Nutrient Management Performance Index (INMPI) for comprehensive assessment and ranking of INM treatments in carrot (Daucus carota L.) cv. Kuroda Improved under Southern Telangana conditions. Pooled mean data on growth, yield, quality, and economic parameters were standardized using Z-score normalization, and an index was constructed with weighted contribution of traits (growth 0.20, yield 0.40, quality 0.25, economics 0.15). INMPI values revealed clear differentiation among treatments. The integrated application of recommended dose of fertilizers combined with farmyard manure, vermicompost, and biofertilizers (T9) recorded the highest INMPI (1.55), followed by partial integration of organic manures (T8, 1.06). Treatments receiving sole nutrient sources recorded lower index values. The index-based approach provided a holistic, objective evaluation of INM practices, offering a practical tool for identifying superior nutrient management strategies for sustainable carrot production.
