An experiment to know the effect of fertigation on growth, yield and quality of okra. Var COBhH 1 was carried out during the year 2011 to 2013 at the Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. The experiment was laid out in randomized block design with six treatments and replicated four times. The treatment combination includes raised bed cultivation, drip irrigation, fertigation, plastic mulch, foliar spray of WSF and micronutrients. The results revealed that okra raised bed + drip irrigation + plastic mulch + fertigation + foliar spray of WSF (19:19:19 @ 10 g/lit. 5 times) + Mixture of all micronutrients (T1) recorded the days to 50% early flowering (43.7days), highest plant height (175.4cm), fruit length(13.8cm), fruit girth (6.48 cm), No. of fruits/plant (25.0), fruit yield/plant (0.466 kg), fruit yield/hectare (201.2.0 q) and economic returns (1.89) when compared to farmers practice (T6) which recorded 155.4 q/ha. Therefore (T1) raised bed + drip irrigation + plastic mulch + fertigation + foliar spray of WSF (19:19:19 @ 10 g/lit. 5 times) + mixture of all micronutrients can be recommended for getting increased growth, flowering and the highest yield for okra under kharif cultivation.
