摘要：The phenomenon of global warming and the depletion of the ozone layer due to the increase in greenhouse gas emissions has an effect on rising sea levels due to the melting of ice in the polar of the earth, potential pairs of saline water occur on land. This event could threaten the continuity of shallot cultivation on the northern coast of Java Island. Salinity causes disruption of germination and growth of shallots, as well as physiological disorders. This study aimed to determine the tolerance level of salinity, the effect of salinity on the nutrient's uptake and productivity of shallots on Alfisols. This study used a completely randomized design (CRD) with 2 factors, (1) the level of salinity (0, 1, 2 and 3 dS m-1) and shallot varieties (Purbalingga and Brebes). The salinity increased 1 to 3 dS m-1 tends to decresae N, P, K uptake, the yields of Shallot and exchangeable-Ca. The soil pH, electrical conductivity and exchangeable-Na were increased with increasing salinity of water irigation.
