Abstract
Okra (Abelmoschus esculentus) is a nutritional powerhouse in addition to being a delicious food. It is high in vitamins, fiber and antioxidants and is essential for maintaining overall health and digestive health. Fertilizer application is crucial for boosting crop productivity, but excessive use can negatively impact plant growth. This experiment aimed to explore the comparative effect of various fertilizers on the growth and yield attributes of Abelmoschus esculentus. Phytochemicals tests were also performed to check the different compounds present in Okra plant. The experiment involved six different treatment groups i.e. control (T0), compost (T1), NPK (T2), FLF+compost (T3), FLF+mustard cake (T4) and DAP+urea across 18 pots with three replicates. Growth and yield parameters were determined. T3 was most effective in enhancing growth, yield and quality of okra in comparison to the fertilizers. It maximally increased plant height (87.4 cm), leaf length (19.4 cm), number of leaves (28), number of flowers per plant, pod length (10.15 cm), pod diameter (11.63 cm), pod weight (10.312 g), number of pods, number of seeds per pod (60.5), earliest flowering (52 days) and maximum yield. The maximum calcium, magnium, zinc and copper was found in the plants treated with T3. It is recommended that FLF+compost should be used as the good nutrient source for increasing the productivity of the okra.
