Field experiment was conducted during kharif, 2021 at Agronomy Farm, Department of Agronomy, College of Agriculture, Dapoli, Ratnagiri, Maharashtra in lateritic soils of Konkan to study the effect of different plant growth regulators on growth, yield and yield attributing characters of kharif Okra (Abelmoschus esculentus L.) The treatments comprise of various levels of bio-stimulant viz., 100, 175, 250, 325, 500 g ha^-1 and triacontanol 250 ml ha^-1 along with RDF which are applied on okra after sowing. Significantly positive effects and higher values were observed on plant height, number of functional leaves plant^-1 and dry matter production at 60 DAS (Days after sowing) and 90 DAS of okra crop with the application of bio-stimulant @ 500 g ha^-1 (T₆) whereas, least values were recorded with untreated control or RDF only (100: 50: 50 NPK kg ha^-1) treatment. Significantly higher fruit yield (16.34 t ha^-1) was observed when biostimulant @ 500 g ha^-1 (T₆) was applied over other treatments and lower fruit yield was observed with respect untreated T₁ (applied RDF only) treatment.
