L-Methionine (L-MET) is an established precursor of ethylene (C2H4) which is known to induce early flowering and ripening of fruits. Therefore, exogenous application of L-MET may induce early flowering in okra. Impact of soil and foliar applied L-MET on growth and performance of okra was investigated in a pot experiment. Different levels of L-MET were applied to the soil (0, 20, 40 and 80 mg kg-1 ) and okra (0, 5, 10 and 20 mg L-1 ) in two splits (15 and 30 days after sowing). For foliar application, 0.1% Tween 20 was used as a binding agent. Results revealed that L-MET applied at 10 mg L-1 (foliar application) and 40 mg kg-1 soil had a significant effect on the growth, yield and physiological parameters of okra as compared to untreated control. Foliar application of L-MET increased the number of flowers, number of fruits, root length, shoots fresh and dry weight, photosynthetic rate, chlorophyll contents and fruit yield up to 77, 96, 71, 64, 65, 71, 60 and 64%, respectively. In the case of soil applied L-MET, up to 97, 85, 96, 77, 82, 92, 54 and 81% increase in growth and yield parameters, respectively, was observed compared to untreated control. These results imply that soil and foliar application of L-MET could be effective in inducing more flowering and promoting growth and yield of okra
