Field experiment was conducted to study the effect of graded doses of N, P and different biofertilizers viz., Azospirillum and phosphobacteria along with growth regulators viz., Naphalene Acetic Acid -50 ppm and Gibberellic Acid -100 ppm on growth and yield of okra (Abelmoschus esculentus) at Agricultural College & Research Institute, Madurai. The highest physiological and biochemical parameters viz., dry matter production (2680.8 kg/ha at 125th DAS), crop growth rate (17.9 g m-2 day-1 85 - 125th DAS), relatively growth rate (0.0164 mg g-1 day-1 at 85 - 125th DAS), ascorbic acid (13.7 mg/100 g of fruits) crude fibre (6.1 %), calcium (0.073 %) and magnesium (0.042 %) was recorded in the treatment (T 15) 75 per cent recommended dose of N, P + 100 % K + Azospirillum + Phosphobacteria + GA3 –100 ppm.
