摘要

An investigation was conducted during 2021–2022 at the College of Horticulture, Chiplima, Sambalpur, Odisha University of Agriculture and Technology to evaluate impact of nine nutrient management treatments, combining organic manures, inorganic fertilizers, and biofertilizers, on four-year-old ‘Bhagwa’ pomegranate plants grown in sandy loam soil. The treatments included variations of the recommended dose of fertilizers (RDF), supplemented with farmyard manure (FYM), vermicompost, poultry manure, and biofertilizers (Azotobacter and PSB), along with a control receiving no external inputs. The treatment combinations were as follows: T1: RDF (500 g N: 125 g, P2O5: 250 g K2O)/Plant, T2: Half of the RDF, T3: 75% of ‘N’ of RDF + Full ‘P’ + Full ‘K’ + 25% N through FYM, T4: 75% of ‘N’ of RDF + Full ‘P’ + Full ‘K’ + 25% N through FYM + Azotobacter + PSB, T5: 75% of ‘N’ of RDF + Full ‘P’ + Full ‘K’ + 25% N through Vermicompost, T6: 75% of ‘N’ of RDF + Full ‘P’ + Full ‘K’ + 25% N through Vermicompost + Azotobacter + PSB, T7: consists of 75% of the nitrogen from RDF, full phosphorus and potassium, with 25% nitrogen supplied through poultry manure, T8: 75% of ‘N’ of RDF + Full ‘P’ + Full ‘K’ + 25% N through Poultry manure + Azotobacter + PSB, T9: (No manures and fertilizers or biofertilizers). The results showed that the T8 treatment, involving 75% RDF‑N, full phosphorus and potassium, 25% N through poultry manure, and biofertilizers, was the most effective. This treatment achieved the highest fruit yield (7.54 kg/plant, 8.38 t/ha), number of fruits per plant (44), and average fruit weight (171.3 g). It also significantly improved fruit quality, including maximum total soluble solids (TSS: 15.30° Brix), aril weight (104.65 g), and juice content, while recording the lowest acidity (0.43%). Conversely, the control (T9) exhibited the lowest values across all parameters. The superior performance of T8 was attributed to the balanced nutrient availability and uptake facilitated by the integrated use of organic, inorganic, and biological inputs.
