Resumo: | http://dx.doi.org/10.5902/198050989282Ilex paraguariensis is considered a low P-requiring species because it grows naturally in soils with low P content, although no much information is also available for N and K requirements. This trial aimed to evaluate the effect of increasing P rates, combined with N and K rates on Ilex paraguariensis growth and its mineral composition. Phosphorus rates of 0, 100, 200, 400 e 600 mg dm-3 of P2O5 were combined with 0, 50 e 100 mg dm-3 of N e K2O. The fertilizers were mixed with the soil and placed in plastic pots of 2.9 dm3. Seedlings of Ilex were transplanted to the pots and grown for 120 days. Ilex seedling growth was affected by the interaction of P and NK rates. The best P rate was between 18.5 and 28.6 mg dm-3and the highest growth was obtained when P was combined with 100 mg dm-3of N and K2O. Iron deficiency symptoms appeared at the P rates of 400 and 600 mg dm-3 of P2O5. It can be concluded that Ilex responds to increasing P rates, as long as plant N, K and Ca requirement is met. |

Diante disto, o objetivo deste trabalho foi avaliar o crescimento, teor de nutrientes no solo e em plantas jovens de erva-mate submetidas a doses de P combinadas com NK. Aplicou-se 0, 100, 200, 400 e 600 mg dm-3 de P2O5 combinados com 0, 50 e 100 mg dm-3 de N e K2O a um Latossolo Vermelho distrófico. Três mudas de erva-mate foram transplantadas para vasos com 2,9 dm3 de solo. Aos 120 dias determinaram-se a altura, diâmetro do caule, comprimento e volume radicular e produção de matéria seca da parte aérea e radicular das mudas. Determinaram-se os teores de N, P, K, Ca, Mg, Fe, Cu, Zn, Mn e Al das folhas e raízes, além do conteúdo de N, P, K, Ca e Mg. Amostras de solo foram submetidas à análise química. O crescimento da erva-mate foi afetado pela interação entre P e NK, demonstrando melhor crescimento quando o teor de P no solo estava entre 18,5 a 28,6 mg dm-3 combinado com 100 mg dm-3 de N e K2O. Em doses superiores a 400 mg dm-3 de P2O5, as folhas passaram a apresentar clorose internerval, sintoma típico de deficiência de Fe. A ordem dos macronutrientes mais exigidos e que mais contribuíram para o crescimento da erva-mate foi P, N, K, Mg e Ca. A erva-mate cresce bem em solos com altos teores de P, mas depende da boa disponibilidade de N, K e Ca.Universidade Federal de Santa Maria2013-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/928210.5902/198050989282Ciência Florestal; Vol. 23 No. 2 (2013); 363-375Ciência Florestal; v. 23 n. 2 (2013); 363-3751980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/9282/pdfSantin, DelmarBenedetti, Eliziane LuizaBastos, Marília CamottiKaseker, Jéssica FernandesReissmann, Carlos BrunoBrondani, Gilvano EblingBarros, Nairam Félix deinfo:eu-repo/semantics/openAccess2017-04-17T14:16:51Zoai:ojs.pkp.sfu.ca:article/9282Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-17T14:16:51Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
