YIELD PERFORMANCES OF VEGETABLE AND SPICE CROPS ON FLOATING BED

An experiment was evaluated the yield performances of some vegetable and spice crop on floating bed. Ten farmers were selected near road side of Kotalipara-Rajoir and Kotalipara-Paisarhat under the upazila of Kotaliparain Gopalganj district for this experiment. Ten dhap has been constructed by ten farmers. The main component of dhap (floating agriculture) was water hyacinth (bulbous plant with bell shaped racemes especially purplish blue which grows in the water). The result indicated that yield of red amaranth, indian spinach, okra and turmeric was higher on D₅ than the D₁, D₂, D₃, D₄, D₆,  D₇,  D₈,  D₉ and D₁₀. Average yield of red amaranth, indian spinach, okra, turmeric on Dhap (floating bed) D₅ was 33.0,59.85, 49.0,36.10 t/ha, respectively. Average yield of red amaranth, indian spinach, okra, and turmeric in higher or medium high land 9.88, 12.36,49.40-74.10,13.59-16.06,12-13 ton/ha, respectively in Bangladesh. The experiment showed good result of red amaranth, okra, turmeric except indian spinach. So dissemination of this floating bed cultivation will help to increase the vegetable and spice production by this time.
