Abstract ‒ The objective of this work was to determine the macronutrient
dynamics in leaves and bunches of black pepper (Piper nigrum) throughout
the plant reproductive cycles. The experiment was carried out in a commercial
field of 'Bragantina' black pepper. Leaves and bunches were sampled every 21
days for one year, during two crop cycles. The bunches were sampled from the
twenty eighth day after the appearance of inflorescences until the complete
fruit maturation. Samples of leaves and bunches were dried, and the contents
of N, P, K, Ca, Mg, and S were determined. N, K, and Ca were the most
common macronutrients found in the bunches and leaves of black pepper. The
accumulation of dry matter in the bunches was similar for both cycles and it
was adjusted to the linear and quadratic models. The accumulation and content
of macronutrients followed the dry matter behavior trend. Macronutrient
contents in leaves oscillate during the year, and K and Mg vary more than N,
P, Ca, and S. The macronutrient contents in black pepper leaves and bunches
depends on the plant vegetative stage, and this variation should be considered
in the planning of the fertilization management.

Resumo – O objetivo deste trabalho foi determinar a dinâmica de
macronutrientes em folhas e cachos de pimenta-do-reino (Piper nigrum), ao
longo dos ciclos reprodutivos da planta. O experimento foi realizado em uma
lavoura comercial de pimenta-do-reino 'Bragantina'. Folhas e cachos foram
amostrados a cada 21 dias, por um ano, durante dois ciclos de cultivo. Os
cachos foram amostrados desde o vigésimo oitavo dia após o lançamento
das inflorescências até a maturação completa dos frutos. As amostras de
folhas e cachos foram secas, e os conteúdos de N, P, K, Ca, Mg e S foram
determinados. N, K e Ca foram os macronutrientes mais comuns nos cachos
e nas folhas de pimenta-do-reino. O acúmulo de matéria seca nos cachos de
pimenta-do-reino foi similar nos dois ciclos e foi ajustado aos modelos linear e
quadrático. O acúmulo e o conteúdo de macronutrientes seguiram a tendência
de comportamento da matéria seca. O conteúdo de macronutrientes nas folhas
oscila durante o ano, e K e Mg variam mais do que N, P, Ca e S. O conteúdo de
macronutrientes em folhas e cachos de pimenta-do-reino depende do estádio
vegetativo da planta, e essa variação deve ser considerada no planejamento do
manejo de adubação.
