Zusammenfassung:	A spatially homogeneous and anisotropic Bianchi type-V universe filled with two minimally interacting fields; matter and holographic dark energy components is in investigated in the scalar-tensor theory of gravitation proposed by Saez and Ballester (Phys. Lett. A 113:467, 1986 ). To obtain a determinate solution of the field equations we have used the fact that the scalar expansion is proportional to the shear scalar. Some physical and kinematical properties of the model are also discussed.
