Resumo: | Palms have high nutrient demand. For this reason, the effects of NPK fertilization on the initial growth of peach palm (Bactris gasipaes Kunth) were studied in a field experiment, from November 1990 to April 1993. The trial was set up on an allic, previously limed soil, in Ubatuba, SP, Brazil (23º27'S, 45º04'W, 6 m asl; "Cfa" climate). A fractional factorial experimental design (½ of 4³) was utilized, with two blocks, one replication, 24 inner plants per plot and double border rows. Treatments were composed of four rates of nitrogen (0 to 400 kg N ha-1 year-1), phosphorus (0 to 200 kg P2O5 ha-1 year-1) and potassium (0 to 200 kg K2O ha-1 year-1), applied in stripes and divided in five annual applications. The fertilizers used were: calcium nitrate, triple super phosphate and potassium chloride. Plants were cultivated in a 2 × 1 m array, and periodically evaluated in relation to diameter of main stem, number of offshoots and percentage of plants with offshoots. In this sandy and low fertility soil, peach palm growth responses in relation to N and K amendments were linear and positive. Initial responses were observed three months after fertilizer application. No isolated effects of P fertilization, nor significant interactions among fertilizers were observed. Maximum growth responses were reached with 400 kg N ha-1 year-1, 0 kg P2O5 ha-1 year-1 and 200 kg K2O ha-1 year-1. |

A fractional factorial experimental design (½ of 4³) was utilized, with two blocks, one replication, 24 inner plants per plot and double border rows. Treatments were composed of four rates of nitrogen (0 to 400 kg N ha-1 year-1), phosphorus (0 to 200 kg P2O5 ha-1 year-1) and potassium (0 to 200 kg K2O ha-1 year-1), applied in stripes and divided in five annual applications. The fertilizers used were: calcium nitrate, triple super phosphate and potassium chloride. Plants were cultivated in a 2 × 1 m array, and periodically evaluated in relation to diameter of main stem, number of offshoots and percentage of plants with offshoots. In this sandy and low fertility soil, peach palm growth responses in relation to N and K amendments were linear and positive. Initial responses were observed three months after fertilizer application. No isolated effects of P fertilization, nor significant interactions among fertilizers were observed. Maximum growth responses were reached with 400 kg N ha-1 year-1, 0 kg P2O5 ha-1 year-1 and 200 kg K2O ha-1 year-1. As palmeiras apresentam grande demanda por nutrientes. Por este motivo, o efeito da adubação NPK no crescimento de pupunheiras (Bactris gasipaes Kunth) foi estudado durante 30 meses (11/90 a 04/93) em experimento conduzido a campo em solo Aluvial álico (corrigido por meio de calagem) em Ubatuba, SP (clima "Cfa"). Utilizou-se o delineamento de blocos ao acaso, com uma repetição, em esquema fatorial fracionado (½ de 4³), com tratamentos dispostos em dois blocos, parcelas úteis de 24 plantas e bordaduras duplas ao redor. Foram testadas quatro doses de nitrogênio (0, 100, 200 e 400 kg ha-1 ano-1 de N), fósforo (0, 50, 100 e 200 kg ha-1 ano-1 de P2O5) e potássio (0, 50, 100 e 200 kg ha-1 ano-1 de K2O), aplicadas em faixa e divididas em cinco aplicações anuais, utilizando como fontes nitrocálcio, superfosfato triplo e cloreto de potássio. As plantas foram cultivadas no espaçamento de 2 × 1 m, e avaliadas periodicamente quanto ao diâmetro da haste principal, número de perfilhos e porcentagem de plantas perfilhadas. Em solo arenoso e de baixa fertilidade, a pupunheira apresenta resposta linear, positiva e significativa de crescimento às adubações com nitrogênio (N) e potássio (K) e ausência de resposta ao fósforo (P). As primeiras respostas significativas ocorreram três meses depois de iniciadas as adubações diferenciadas. Não houve interações significativas entre N, P e K. O crescimento máximo foi obtido com doses anuais de 400 kg de N, 0 kg de P2O5 e 200 kg de K2O por hectare. Universidade de São Paulo.
