The effect of establishment technique combinations on initial growth of Grevillea robusta was evaluated in the northern area of the province of Corrientes, Argentina. The treatments included the combination of two factors. The first one was applied previous to planting G. robusta and consisted of slash management with two levels: a) slash conservation and, b) slash burning. The second factor consisted of fertilizer application with three levels: a) unfertilized, b) fertilized after plantation establishment and, c) fertilized a year after plantation establishment. The plantation establishment technique combinations changed the initial growth of G. robusta. The best combination was slash burning with fertilization during establishment. With this combination, the plantation achieved a 43.7 % increase in diameter at 36 months of age, which was superior to that obtained with the slash conservation with no fertilization treatment.
