Abstract

Annona crassiflora is a medicinal species and source of food with little information about its nutritional requirements
during the initial phase. Therefore, the objective of this study was to evaluate liming, phosphate fertilization and
its interaction in A. crassiflora seedlings. The experiment was in a 4 × 4 factorial scheme with four replications
in a randomized block design. The base saturations were: 8.3%, 25%, 50% and 75% and phosphorus: 0 mg dm-3,
100 mg dm-3, 200 mg dm-3 and 400 mg dm-3. The variables evaluated were biometrics, biomass and nutritional
analysis. The species responded to the factors in isolation, and the increase in base saturation levels and phosphorus
doses promoted significant effects for biometric variables, biomass, calcium, magnesium, nitrogen, phosphorus
and potassium content. The saturation level promoted the best results, being 75% base saturation, while the highest
phosphorus dosage was 400 mg dm-3.
