Resumo: 	Emergence and seedling growth may be severely affected by salinity, mainly for sensitive crops. The objective of the present study was to verify the tolerance of corn and soybean to the irrigation water salinity (ECi) during the emergence and initial development stages. Seeds of corn, hybrid 'AG-6690', and soybean, cv. 'Conquista', were sown in pots containing material from a sandy-loam soil and irrigated with water of increasing salinity levels, from 0.3 to 5.9 dS m-1, giving nine levels of ECi obtained by the addition of an equivalent proportion of sodium and calcium chloride, except for ECi = 0.3 dS m-1 (tap water). Emergence of corn was not affected by salinity but seedling development was reduced for ECi above 1.5 dS m-1. Emergence and growth of soybean were reduced by water salinity and the crop was more tolerant during the emergence (ECi = 2.7 dS m-1) than in the initial development (ECi = 1.0 dS m-1) stage. Salinity of soil solution (ECs) was linearly correlated to ECi and affected the growth of corn and soybean for ECs higher than 3 and 2 dS m-1, respectively.
