MACEDO, Sheron Torres de  and  TEIXEIRA, Paulo César. Lime and phosphorus for araza seedling formation. Acta Amaz. [online]. 2012, vol.42, n.3, pp.405-412. ISSN 0044-5967.

The araza (Eugenia stipitata McVaugh) is a fruit species cultivated in domestic scale in the Amazon region. However, little is known about their nutritional needs during the initial phase. The aim of this study was to evaluate the effect of lime and phosphorus on growth and nutrition of seedlings of araza. The experiment was conducted in greenhouse, with samples of a Yellow Oxisol dystrophic in randomized blocks and factorial scheme 5 x 5: five doses of lime (0, 1.37, 2.83, 4.29 and 5.75 g per seedling) and five doses of phosphorus (0, 100, 200, 400 and 600 mg P kg-1) with four replications. Ten months after transplantation, the growth in height and diameter, shoot and root dry matter, and nutrient accumulation in the shoots were evaluated. Lime rates significantly influenced the height, diameter, and shoot, root and total dry weight. The phosphorus levels affected only the growth in diameter and dry matter in shoot and total. There was a significant effect of lime and phosphorus on the content of macro and micronutrients in the shoot, except for Cu, influenced only by limestone. The best development of araza seedlings can be obtained with application of up to 3.77 g of lime and 6.21 g of superphosphate per seedling.
