ABSTRACT: 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.
