Abstract

In order to evaluate the effects of different doses of mineral and organic fertilizers in agronomic characteristics of lettuce (Lactuca saliva L.), an experiment was carried out in the district of Rio Verde (GO). The experimental design consisted of nine treatments (combination of the levels 0 kg.ha-1, 18,500 kg.ha-1 and 36,900 kg.ha-1 of organic fertilizer with levels 0 kg.ha-1, 870 kg.ha-1 and 1,750 kg.ha-1 of mineral fertilizer), and 3 repetitions. Weight of the fresh matter (g.plant-1), weight of the matter in evaporates (g.plant-1), matter text evaporates (%) width and length of the leaf of the aerial part of plants were evaluated. The employment of the dose of 18,500 kg.ha-1 of organic fertilizer and 1,750 kg.ha-1 of mineral fertilizer were the ones that provided the best productions, low financial cost aand contributed enormously to most of the evaluated characteristics.
