Abstract: A pot experiment was conducted to study the effects of irrigation water salinity, FYM, gypsum and potassium on biomass yield and nutrient accumulation of maize in coastal saline soil. Application of saline water up to 12 dS m-1 significantly increased the biomass yield (7-12%) over control but, decreased by 11% at 16 dS m-1. Combined application of recommended dose of fertilizer (RDF) + FYM, RDF + gypsum or RDF + K was found beneficial for maize by increasing the biomass yield (2-43%), K accumulation (15-29%), K uptake (22-63%) and K+ / Na+ ratio as compared to RDF alone. The adverse effect of Na decreased due to irrigation water salinity was reduced with amendments by decreasing the Na content (27-38%) and uptake (19-27%) over RDF alone. It is concluded that saline water up to 12 dS m-1 along with amendments can be used for maize in coastal saline areas.
