A pimenta-longa (Piper hispidinervum C. DC.) é uma das principais fontes alternativas para a produção de safrol empregado como matéria prima na fabricação de inseticidas naturais e aromatizantes. O objetivo da pesquisa foi avaliar o efeito da omissão dos macronutrientes e micronutrientes, sobre a composição mineral de plantas de pimenta-longa, e caracterizar os sintomas de deficiências decorrentes dessa limitação, utilizando-se da técnica do elemento faltante. O experimento foi conduzido em casa de vegetação, com quatro repetições e doze tratamentos, completo e omissão individual de N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn em delineamento inteiramente ao acaso. Os valores dos teores foliares nos tratamentos com omissão dos nutrientes foram inferiores àqueles obtidos no tratamento completo. As omissões individuais dos nutrientes promoveram alterações na composição mineral de macro e micronutrientes.

DC.) is one of the main alternative sources for the production of safrol used as raw material in the manufacture of insecticides and natural flavoring. The objective of this research was to evaluate the effect of omission macronutrients and micronutrients, on the mineral composition of long pepper plants, and featuring the symptoms of deficiencies resulting from this limitation, using the missing element technique. The experiment was conducted in a greenhouse, with four replicates and twelve treatments, complete and individual omission of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn in a completely randomized design. Foliar levels in treatments with the omission of nutrients were lower than those obtained in the complete treatment. The omission of individual nutrients promotes changes in the mineral composition of macro and micronutrients. The levels of macronutrients (g kg
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
