An experiment was carried out during the period of March to July of 2012 in the Agrarian Science Center of Federal University of Paraiba, Areia, Paraiba State, Brazil, in order to evaluate the initial growth of Licania rigida plants by height, stem diameter, leaf area, total chlorophyll content and biomass of the roots and of the aerial parts of the plants as function of water salinity and bovine biofertilizer and with potassium in the soil. Treatments were arranged in entirely randomized design, with six replicates, in factorial scheme 5 x 2 x 2, corresponding to waters with electrical conductivity of 0.5; 1.5; 3.0; 4.5 and 6.0 dS m-1 in soil without and with 300 mL of bovine biofertilizer applied one time on soil surface, and without and with 1.4 g of potassium chloride. The increment of salinity in irrigation water inhibited the growth and the quality of the seedlings, but with more loss in plants of the treatments without bovine biofertilizer and without potassium chloride. The plants cultivated in soil with potassium showed better growth in relation these of the treatments without the mineral fertilizer.
