This work had the objective of investigate the nutritional requirements of Cedar (Cedrela fissilis) species. Theexperiment was performed in a greenhouse to assess effects of complete fertilization and of fertilization with missing nutrients onseedling development. The experiment consisted of 10 treatments and 5 replications in a complete randomized block design. Vaseswith a capacity for 5 kg of soil were used, with one plant unit per vase and a red-yellow latosol substratum of poor fertility, applyingthe 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 basediameter and dry matter yield at 110 days after planting. Results demonstrated that N and P are the most limiting nutrients for thedevelopment of the species. Considering these limitations and defining shoot dry matter yield in the complete treatment as aparameter, the nutrient requirements of cedar seedlings were as follows, in decreasing order: P > N > K > B > S > Ca > Zn > Mg. |
