The objective of the study was to assess different substratecompositions for the production of seedlings in the city of Autazes, in Amazonas state. Eight treatmentsarranged in random blocks experimental design, with five replicates were tested. The treatments were: cattlemanure, lime, corrective phosphate, fertilizer with NPK, lime + correction phosphate, corrective phosphate+ fertilizer with NPK, lime + fertilization with NPK and lime + corrective phosphate + fertilizer with NPK.After 120 days, the following characteristics were assessed: height of shoot, diameter of the neck, shoot, parootand total dry matter, nutrient levels and amounts in shoot dry matter. The results corroborate that alltreatments provided improvements in the soil attributes. Those improvements caused larger readiness ofnutrients for the plants, which provided an appropriate growth of Macacaúba seedlings. The plants thatgrew on cattle manure treatment showed higher nutrient absorption and growth rates in a smaller periodof time. It suggests that cattle manure soil is the most suitable in the production of Macacaúba seedlings.</p>
