The experiment was conducted at the farmer’s field of FSRD site, Hazirhat, Noakhali, during the Rabi season (2014-15 & 2015-16) to observe the effect of different amount of water hyacinth as mulch on potato and tomato at the saline soil of Noakhali. Different mulch treatments viz. T1 = No mulch, T2 =56 t/ha, T3 = 62 t/ha and T4 = 68 t/ha were tested in the experiment. Different amount of water hyacinth had marked effect on soil moisture conservation to reduce the adverse effect of soil salinity. The maximum soil moisture (%) status and the lowest salinity level (dS m-1) recorded both for potato and tomato at harvest stage mulched with 68 t water hyacinth ha-1. The highest yield 26.46 t ha-1 and 67.29 t ha-1coupled with gross margin 165800 tk. ha-1 and 646930 tk. ha-1 obtained from T4 treatment both for potato and tomato, respectively. Cultivation of Potato and Tomato with water hyacinth as mulch @ 68 t ha-1 might be a good option to minimize the adverse effect of soil salinity as well as for higher yield and economic return at the saline soil of Noakhali.
