Resumo: | This work hat the objective of investigate the nutritional requirements of Cedar (Cedrela fissilis) species. The experiment was performed in a greenhouse to assess effects of complete fertilization and of fertilization with missing nutrients on seedling development. The experiment consisted of 10 treatments and 5 replications in a complete randomized block design. Vases with a capacity for5 kg of soil were used, with one plant unit per vase and a red-yellow latosol substratum of poor fertility, applying the following treatments: one complete treatment with N, P, K, Ca, Mg, S, B and Zn; eight treatments, each with one missing nutrient (-N, -P, -K, -Ca, -Mg, -S, -B and -Zn), and one control treatment with natural substratum. It was assessed shoot height, stem base diameter and dry matter yield at 110 days after planting. Results demonstrated that N and P are the most limiting nutrients for the development of the species. Considering these limitations and defining shoot dry matter yield in the complete treatment as a parameter, the nutrient requirements of cedar seedlings were as follows, in decreasing order: P > N > K > B > S > Ca > Zn > Mg. |

O experimento foi constituído de 10 tratamentos e 5 repetições, em delineamento de blocos inteiramente casualizados. Foram utilizados vasos com capacidade 5 kg de solo, contendo uma planta por vaso e como substrato um latossolo vermelho amarelo de baixa fertilidade. Os tratamentos aplicados foram o completo com N, P, K, Ca, Mg, S, B e Zn; outros 8 tratamentos como missão de um nutriente por vez (-N, -P, -K, -Ca, -Mg, -S, -B e -Zn ) e um último tratamento com o substrato natural como testemunha.Avaliou-se altura da parte aérea, diâmetro do colo e produção de matéria seca aos 110 dias após o plantio. Os resultados encontrados nas condições desse estudo indicaram ser N e P os nutrientes mais limitantes para o desenvolvimento da espécie. Quanto à limitação, os nutrientes exigidos pelas plântulas, tomando como parâmetro a produção de matéria seca da parte aérea do tratamento completo, foram, em ordem decrescente, P > N > K > B > S > Ca > Zn > Mg.Universidade Federal de Lavras (UFLA)2015-05-222017-08-01T20:13:59Z2017-08-01T20:13:59Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfSOUZA, P.
