<br/><br/> <br/><br/>Abstract<br/><br/>Acrocarpus fraxinifolius, known as Indian cedar, has little forestry development in Brazil. Thus, the objective of this<br/>study was to find the best relation between nutrition and container (tube) volume in seedlings of this species. The<br/>experiment was carried out in a 2 × 8 factorial scheme (2 containers and 8 fertilizers), with polypropylene tubes of<br/>50 and 110 cm³ being tested, and the following fertilization treatments: one control, 4 increasing doses of osmocotee<br/>plus: 3, 5, 7, 9 kg per m³ of substrate, and fractionated mineral fertilizations with cover manure. It was possible to<br/>note that the tube with the highest volume (110 cm³) presented better results for the morphological characteristics.<br/>However, when analyzing the physiological variables, it is clear that the 50 cm³ tubes presented similar results to<br/>the largest volume tube when well fertilized. It is concluded that the indicated to form seedlings of the species is the<br/>combination of tubes of 50 cm³ with the fertilization or double of this recommendation.<br/><br/>Keywords: Indian cedar, fractional fertilization, osmocotee.
