With the purpose of evaluating effects of salinity of the irrigation water in different genotypes of precocious dwarf cashew, an experiment was conducted in greenhouse at the Experimental Station of Pacajus, belonging to Embrapa Tropical Agroindústria in the State of Ceará. The treatments in randomized block design consisted of six levels of electrical conductivity of water (ECw: 0.5; 1.5; 2.5; 3.5; 4.5 and 5.5 dS m-1) and two types of seedlings (CCP06 and CCP1001) with four replications, totaling 48 units each consisting of 54 plants. The irrigation waters were prepared maintaining a proportion of 7:2:1 for the ions Na:Ca:Mg. The effects of the salinity were evaluated on germination, germination period, number of leaves, plant height, stem diameter and total dry weight 25 and 40 days after planting; the plantlings were evaluated 30 days after grafting. With the exception of germination percentage, other variables were found to be affected negatively by salinity of the irrigation water and between clones the growth of CCP1001 was affected more adversely.
