Abstract: An experiment was carried out at Coastal Soil Salinity Research Station, Dhanti–Umbharat, Navsari, Gujarat to study the effect of source of irrigation (S1-sea water, S2-aquaculture effluent) and fertilizer dose (F1-No fertilizer, F2- 125:37.5:25 kg ha-1 NPK, F3- 250:75:50 kg ha-1 NPK) on soil fertility, salinity and aggregation in Salicornia brachiata Roxb. Results revealed aquaculture effluent irrigation and 100% recommended fertilizer dose increased SOC content and soil CEC by 38.6 and 20.0, and 17.1 and 2.14% at 0-15 and 15-30 cm soil depth, recpectively. The soil available nutrients increased, soil salinity parameters decreased and soil aggregation improved with aquaculture effluent irrigation and 100% recommended fertilizer dose, irrespective of soil depth. Along the depth, SOC, cationic nutrient, CEC, SAR, ESP and aggregate (>1mm) decreased, while, anionic nutrient and pH increased. Thus, the application of aquaculture effluent irrigation water and 100% recommended fertilizer dose were suggested for Salicornia brachiata Roxb. in Navsari, Gujarat.
