MANEJO DE COLHEITA E ADUBAÇÃO FOSFATADA NA CULTURA DA ERVA-MATE (<i>Ilex paraguariensis</i>) EM FASE DE PRODUÇÃO

Abstract: RESUMOAs sucessivas colheitas na base de folhas (FO) e galhos finos (GF), sem a necessária reposição nutricional, têm proporcionado quedas na produtividade brasileira de erva-mate nos últimos 20 anos. Neste sentido, o objetivo do trabalho foi avaliar a influência do intervalo de colheita e da adubação fosfatada na disponibilidade de fósforo (P) no solo, na produtividade e no estado nutricional da erva-mate.O experimento foi conduzido em São Mateus do Sul -PR, em Latossolo Vermelho-Escuro álico, onde se avaliar… Show more

“…Studies using different doses of P and K in the production of yerba mate seedlings indicate that the addition of these nutrients positively influences all plant growth variables (Santin et al, 2017). In the present study, we obtained a significant seedling growth with poultry manure, mainly composed of P and K (6.59 % of P2O5 and 2.51 % of K2O).…”

“…P is the most present macronutrient in poultry manure composition, and it was the one with the highest leaf content compared to what is commonly found in yerba mate. Leaf content of 1.2 to 1.6 g kg -1 of P is considered adequate for yerba mate (Santin et al, 2017). At the best growth dose, BRS408 presented 4.0 g kg -1 of P (Figure 4A).…”

“…Sabe-se que a erva-mate responde positivamente a adubação fosfatada (SANTIN et al, 2013;SANTIN et al, 2016), assim a dose de cama de frango foi adicionada para suprimento de fósforo. Desta forma, possivelmente, o fósforo presente no composto orgânico tenha sido fundamental para a resposta positiva da erva-mate a adubação neste trabalho.…”
