Soil salinity reduces soil fertility and negatively affects the vast majority of crops of economic importance. In the agrochemicals market, various products are offered as salt remover, which theoretically can greatly help to improve the properties of a saline soil. The objectives were: to evaluate the effect of salt dispersants on growth and dry matter production in corn (Zea mayz L.); and determine the effect of the dispersants on the concentration of the elements that determine salinity. With the purpose of observing the effect of different dispersant products, the present experimental work was proposed, which was installed in the soil fertility greenhouse “Sven Villagarcía“ of La Molina Agrarian University, with soil from the district of Catacaos, in the province of Piura. In the work three variables were established; washing of the soil (S1 = soil not washed and S2 = soil washed); effect of the dispersant (F1 = Dispersal, F2 = Saltrad and F3 = Gypcal); and doses (D1 = Dose 1, D2 = Dose 2 and D3 = Dose 3). Three measurements of plant height were made at 25, 40 and 90 days according to their phenological status. At the end of the experiment the dry matter of foliage and roots were evaluated, subsequently the soil salinity analysis was performed. The experimental design of randomized complete blocks with factorial arrangement 2x3x3 + 1 control was used, considering in total 19 treatments each with 4 replicates. The results obtained for plant height that presented significant responses were S1F2 (39.66 cm), S2F1 (50.72 cm), S2D2 (41.67 cm), S2D3 (47.87 cm), F1D3 (48.21 cm) and F2D2 (47.87 cm); for dry matter of foliage the interactions that presented significant answers were S2F1D1 (18.24 g / pot) and S2F1D3 (18.64 g / pot); and finally, for root dry matter were found significant responses for the interactions S2F1D2 (3.44 g / pot) and S2F2D3 (3.78 g / pot). No significant differences were found in soil salinity analysis.
