The present study evaluated the interactive effects of inorganic fertilizer (NPK), bio-inoculants, and micronutrient supplementation okra (Abelmoschus esculentus L. ‘Kashi Kranti’) cultivation in the year 2024. A factorial randomized block design with 64 treatment combinations was implemented: four NPK levels (80:40:40, 100:50:50, 120:60:60, 140:70:70 kg/ha), four bio-inoculant regimes (none, Azotobacter 1000 ml/ha, PSB 1000 ml/ha, Azotobacter + PSB 1000 + 1000 ml/ha), and four micronutrient treatments (none, Zn 50 ppm, Fe 100 ppm, Zn + Fe 150 ppm) with the objective of effects of nutrient combination on quantitative & qualitative characters in okra.Most of the result shown significant three-way interactions for Plant height (115.3 cm) in F4B4M4, Inter-nodal length (7.98 cm) in F4B4M4 while the other parameters like Number of primary branches per plant (6.20), Number of days to 50% flowering (45.11), Average diameter of fruit (2.47 cm), Average length of fruit (12.72 cm), Fruit yield per plant (233 g), Yield (15.56 T/ha) & Ascorbic acid (16.8 mg/100 g) was best in (F2B4M4) combination of NPK (100:50:50 kg/ha), Azotobacter + PSB (1000 + 1000 = 2000 ml/hBa), and Zn + Fe (150 ppm) consistently produced the most favorable quantitative & qualitative parameters in okra. These findings highlight the potential of integrated nutrient management for sustainable okra production.
