The experiment was carried out conducted during the rabi seasons of 2023-24 and 2024-25 at the Herbal Garden of Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur, Chhattisgarh. The experiment was laid out in a Randomized Block Design (RBD) with 8 treatments and 3 replications. The treatments included various combinations of NPK fertilizers and organic manures (FYM) to (T₁) NPK 30:20:25 kg ha-¹, (T₂) NPK 60:40:50 kg ha-¹, (T₃) NPK 90:60:75 kg ha-¹, (T₄) NPK 120:80:100 kg ha-¹, (T₅) NPK 30:20:25 kg ha-¹ + 5 t fym ha-¹, (T₆) NPK 60:40:50 kg ha-¹ + 5 t fym ha-¹, (T₇) NPK 90:60:75 kg ha-¹ + 5 t fym ha-¹ and (T8) 10 t fym ha-¹ evaluate the effects of integrated and sole nutrient applications on chia performance under partial tree shade. The results revealed that nutrient management significantly influenced the growth, yield, and economic returns of chia. Among all treatments, NPK 90:60:75 kg ha⁻¹ (T₃) recorded seed yield (645.20 kg ha⁻¹), and economic return (₹2,38,221 ha⁻¹ net return with a B:C ratio of 3.80). Initial soil organic carbon was 0.42%, increasing to 0.46-0.53% across treatments, with the highest improvement under NPK 90:60:75 kg ha⁻¹ + 5 t FYM ha⁻¹ (T₇). Available nitrogen improved from 176.21 kg ha⁻¹ to a maximum of 196.42 kg ha⁻¹ under the same treatment. Phosphorus and potassium also increased, especially under integrated management (T₅ to T₇). Soil pH remained nearly stable (6.35-6.65), while EC ranged between 0.25-0.35 dS/m. Integrated application (T₇: NPK 90:60:75 kg ha⁻¹ + 5 t FYM ha⁻¹) also produced competitive results while improving soil organic carbon and supporting Shisham tree growth.
