Zusammenfassung:In oiticica producing regions, there is a lack of technical guidance to improve the quality and performance of oiticica, especially its main product: the oil. One interesting topic for those who are engaged on the economic use of this culture is the moment of the fruit collection with higher oil yield, because after fruit maturity, they fall to the ground and, as soon as they were collected and extracted the oil, it would get a higher yield, resulting in one of the factors responsible for the success of this culture. For this purpose, it was aimed to evaluate the influence of harvesting on the chemical and mineral composition of almonds oiticica, from the city of Pombal, PB, after going through 7 days (week), 30 days (month) and 365 days (year) in storage. We used a completely randomized design with four replications. At the Soil Science and Plant Nutrition Laboratory (LSNP), Embrapa Cotton, Campina Grande, PB was determined: water content, oil content, protein, ash, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) from seeds collected in the agricultural year of 2012, in which the data were analyzed in a completely randomized design with eight replications, and the averages were compared with Tukey test. Based on the results obtained it was concluded that: the oil yield (%) decreases with storage time, and the amounts of N, Ca, S showed high concentration for fruit stored during 7 days. Nas regiões produtoras de oiticica, verifica-se falta de orientação técnica visando melhorar a qualidade e o rendimento da oiticica, especialmente do seu principal produto, que é o óleo. Um tema de interesse dos envolvidos discutido no aproveitamento econômico desta cultura é o momento de coleta dos frutos com maior rendimento em óleo, uma vez que após a maturação dos frutos, estes caem ao solo e, se tão logo fossem coletados e extraído o óleo, seria possível obter maior rendimento, traduzindo-se num dos fatores responsáveis pelo sucesso desta cultura. Com este propósito, objetivou-se avaliar a influência da colheita sobre a composição química e mineral das amêndoas de oiticica, provenientes do município de Pombal, PB, depois de passarem pelo tempo de sete (07) dias (semana), 30 dias (mês) e 365 dias (ano) de armazenamento. No Laboratório de Solos e Nutrição de Plantas (LSNP), da Embrapa Algodão, Campina Grande, PB, determinou-se: teor de umidade, teor de óleo, proteína, cinza, nitrogênio (N), fósforo (P), potássio (K), cálcio (Ca),
