dc.descriptionFertilizers are salts that may increase irrigation water salinity, therefore, fertirrigation management should consider aspects like the injection solution. The electrical conductivity of soil solution (ECs) or the soil saturation extract (ECs) may be used to quantify the amount of salts in soil. The objective of this work was to evaluate the effect of calcium nitrate concentration of the irrigation water on the soil electrical conductivity along the first cycle of banana crop. Treatments consisted of using three calcium nitrate concentrations of the solution (1.0; 2.5 and 4.0 g L-¹) to be injected into a drip and a microsprinkler irrigation system during the first cycle of Terra banana crop. There was no significant difference among soil extract saturation means for the two irrigation systems. The absolute values of the electrical conductivities were larger in the wetted volume under drip irrigation system. There was difference among electrical conductivities related to the concentrations of calcium nitrate of the irrigation water. The 4 g L-¹ concentration means were larger than the ones of other concentrations in most of the cases. The use of 4 g L-¹ concentration resulted electrical conductivities of soil solution and of soil extract saturation larger than 1.0 dS m-¹ for at least 80% and 20% of measurements along of cycle, respectively.
