The forestry nutrition is a current development topic both in plantation and in the nursery stages. In cases like clonal minigardens, there are mother plants that have chlorosis that shows some kind of nutritional decifiency. In a clonal minigarden with Tectona grandis the irrigation system and a treatment application were evaluated by mixing fertilizer doses (organic and salts) with varied irrigation criteria to apply the fertigation technique. The Christiansen and distribution uniformity coefficients were determined for the irrigation system. In addition to the treatments, the weekly factor were also used to evaluate the behavior of teak mother plants considering the sprouts harvest. The irrigation system showed results of its uniformity that placed it in an inacceptable level. Regarding the variable measures (diameter, height, number of leaves and sprouts) there weren´t significant difference (p ≤ 0.05) between treatments but yes between weeks. In this proyect it is concluded that although there weren´t significant difference between treatments, the costs for using salts as fertilizer are considerably lower.
