Some trails were carried out with a view to evaluate the performances of organic and inorganic fertilizers on growth and yield of okra (Abelmoschus esculentus L.) and cucumber (Cucumis sativus L.) in floating bed cultivation applying water hyacinth in 2014 and 2015 at Gopalpur union under Tungipara upazila of Gopalganj district in Bangladesh. The single factor experiment was conducted following Randomized Complete Block Design (RCBD) involving four treatments with three replications viz. T₁: control (without organic and inorganic fertilizer), T₂: cow dung, T₃: recommended dose of NPK and T₄: 50% cow dung + 50% recommended dose of NPK. Different growth parameters in respect of okra grown in 2014 and 2015, the longest plant height (171.73 cm and 164.03 cm), maximum number of branches (5.67 and 5.67) and leaves (60.33 and 69.67) were found in the treatment T₃. Regarding yield parameters, significantly higher number of fruits plant^-1, fruit length (cm), fruit diameter (cm), individual fruit weight (g), fruits weight plant^-1 (g) and yield (t·ha^-1) were 24.00 & 23.33, 16.61 & 16.59 cm, 6.01 & 6.17 cm, 23.47 & 24.74 g, 617.33 & 660.33 g, 13.01 & 13.21 t·ha^-1 obtained respectively grown in 2014 and 2015 by applying the treatment T₃ were identically similar with those in receiving the treatment T₄. The lowest output was recorded in control in both seasons for all the cases. Similar trend of growth and yield were also observed during the cultivation of cucumber under the same treatment conditions in both the seasons. Results revealed that there was no identical differences in growth and yield attributes in between the treatments T₃ and T₄, where as the production cost was subjected to lower in T₄ compare to T₃. However, from the economic point of view, the treatment T₄ i.e. application of 50% cow dung + 50% recommended dose of NPK fertilizers in floating bed cultivation was exposed to be more feasible and suitable as cost effective for the growth and yield of okra and cucumber in the experimental area.
