Doses de fósforo na produção de fitomassa de bertalha

Abstract

A bertalha (Basella alba L.) é uma planta alimentícia não-convencional (PANCs), com potencial produtivo e econômico no Brasil. Entretanto, há ausência de informações quanto ao cultivo, especialmente quanto à adubação fosfatada, assim, objetiva-se avaliar o efeito de doses de fósforo (P) na produção de fitomassa de plantas de bertalha. O experimento foi conduzido na casa de vegetação da Universidade Federal do Recôncavo da Bahia (UFRB). O delineamento utilizado foi o inteiramente casualizado (DIC), com cinco tratamentos: 0; 15,5; 31 (controle); 62 e 93 mg.dm-3 de fósforo (H2PO4-) e cinco repetições. Após 60 dias da aplicação das soluções nutritivas, foram avaliados os parâmetros fisiológicos de qualidade e quantidade da fitomassa. Os resultados foram submetidos à análise de regressão a 5% de significância. As doses de P promoveram o crescimento de plantas de bertalha, em que à medida que aumentaram as doses, a fitomassa das plantas acompanhou esse crescimento, de forma significativa, até a dose 62 mg.dm-3 de P, na qual apresentou seu máximo potencial produtivo. A dose 93 mg.dm-3 de P causou toxidez, reduzindo a produção de todas as massas. Para as clorofilas, observou-se que as menores doses de P apresentaram maiores valores, contudo, tais resultados evidenciaram sintomas de deficiências nutricionais.
