&description=A pot experiment was conducted to investigate the Effect of different reclaimed saline soil on the growth and yield response of water spinach (<i>Ipomoea aquatica</i>) during the period of 22<sup>th</sup> May to 23<sup>th</sup> June, 2017. Soil samples were collected at a depth of 0-15cm from a square area of 1km<sup>2</sup> from Harikhali, under Bagerhat district in Bangladesh. The location of sampling area was 22°40.542′N and 89°31.406′E. Soils mainly dark calcareous. Textural class is Clay loam and Physiography of the soil is Ganges tidal floodplain. The experiment was laid to fit a completely randomized design (CRD) with seven treatments T<sub>0</sub> (Reference soil); T<sub>1</sub> (Cow dung); T<sub>2</sub> (Rice hulls); T<sub>3</sub> (Gypsum); T<sub>4</sub> (CaCl<sub>2</sub>); T<sub>5</sub> (Rice hulls + Cow dung) and T<sub>6</sub> (Gypsum + CaCl<sub>2</sub>). After plant harvesting, the laboratory investigation was carried out in the Soil, Water and Environment Discipline, Khulna University, Khulna, Bangladesh. Yield contributing characters like number of leaves, fresh weight and dry weight were significantly (<i>P<0.05</i>) influenced by different treatments. The study revealed that addition of cow dung, rice husk, gypsum and calcium chloride acted as ameliorant to saline soils and effective in increasing number of leaves per plant, root length per plant (cm), shoot length per plant (cm), fresh weight per plant (gm) and dry weight per plant (gm) compared to reference soil.&picture=http://www.aascit.org/aascit/decorators/img/journal/892.jpg)
