A field experiment titled “Effect of Integrated nutrient management on growth, yield and economic of maize under south eastern Rajasthan” was conducted during the Kharif season of 2023 at the Research Farm, Agricultural Research Station, Ummedganj-Kota, Rajasthan. The experiment comprised 10 treatment combinations: T1 - Absolute control, T2 - 100% RDF, T3 - STCR, T4 - 50% RDF + 50% FYM, T5 - 100% FYM, T6 - 50% RDF + 50% poultry manure, T7 - 100% poultry manure, T8 - 100% RDF + Biofertilizer, T9 - 50% RDF + 50% FYM + Biofertilizer (Azotobacter + PSB), and T10 - 50% RDF + 50% PM + Biofertilizer (Azotobacter + PSB). The field experiment, consisting of ten treatments replicated three times, was laid out in a randomized block design using the maize hybrid variety PHM-3 as the test crop. The results demonstrated that the application of treatment T3 (STCR) recorded the highest growth parameters, including plant height at 30, 60 days after sowing (DAS), and harvest (141.7, 251.7, and 266.9 cm, respectively), plant dry matter (31.7 and 149.7 g plant-1), leaf area index (1.48 and 4.40 cm) and chlorophyll content (1.13 and 2.23 mg g-1) recorded at 30 and 60 DAS. The yield parameters also showed significant improvements, with grain yield (5963 kg ha-1), stover yield (8984 kg ha-1), biological yield (14947 kg ha-1) and economic benefits (net return 105,633 Rs ha-1 and B:C ratio of 2.55).
