Abstract
Acrocarpus fraxinifolius stands out due to its uses in the timber industry and rapid growth. However, information is scarce regarding its fertilization. We aim to understand how soil preparation and phosphorus doses affect A. fraxinifolius initial development. The experimental design used was a randomized block design in a 2 x 5 factorial scheme, consisting of two types of soil tillage (minimum and conventional) and five doses of phosphorus (P) (0, 50, 100, 150, and 200 g of simple superphosphate) with four replications, and plots formed by two plants. The measurement occurs at 30 and 210 days after planting, assessing the height and diameter at the stem height. Initially, the minimum tillage provided had a higher average height and diameter. However, conventional tillage, acidity correction, and fertilization with 108 g of simple superphosphate per plant resulted in Acrocarpus fraxinifolius plants with better growth at 210 days after planting.
