Cerrado biome is responsible for part of Brazilian food production. However, due to inadequate soil management practices, large areas of crop and forage are degraded, leading to environmental and economic losses. A crop-livestock-forest system (CLFS) is a sustainable production strategy that integrates different cultivations. This objective of this study was to evaluate agronomic characteristics and maize (Zea mayz L.) yield when consorciated with Panicum maximum cv. Tamani, cultivated between rows of eucalypts clones. The statistical design used was randomized blocks, constituted by the following treatments: Maize + AEC 043; Maize + AEC 007; Maize + AEC 2111; and Maize + AEC 2034. The analyzed variables included: spikes length, number of rows, number of grains per row, number of grains per spike, and grain yield. Based on the obtained data, it is possible to conclude that trees did not affect maize yield in a CLFS. Considering that only 66% of the area was used for agriculture, maize yield was higher than when it is planted in total area.

Em razão da escassez de informações sobre adubação em acácia-negra, no presente estudo, objetivou-se avaliar o crescimento de plantas de acácia-negra em função de diferentes níveis de adubação com nitrogênio, fósforo e potássio, após seis anos da implantação. O delineamento utilizado foi de blocos ao acaso, com distribuição trifatorial (doses de fertilizantes). Avaliou-se a altura total (m), diâmetro a altura do peito (DAP) (cm) e volume de madeira com casca (m³ ha-1). A acácia-negra apresentou resposta positiva e significativa, de crescimento às adubações com N e P (interação) e ausência de resposta ao K. Para a obtenção do máximo crescimento da acácia-negra, para a condição edafoclimática estudada, deve-se utilizar a dose máxima de nitrogênio (40,0 kg ha-1 de N) e 78,9 kg ha-1 de fósforo, não sendo necessária a adição de potássio via fertilizantes. Due to the lack of information about Black-wattle fertilization, this study evaluated black-wattle plants growth in response to different fertilization levels of nitrogen, phosphorus and potassium six years after implantation. The statistical design used was a randomized blocks with trifatorial distribution. Total height (m), diameter at breast height (DBH) (cm) and stem volume with bark (m³ ha-1) were evaluated. Black-wattle showed a positive and significant growth response to N and P (interaction) fertilizations and absence for K. m To obtain the maximum development of black-wattle, for the soil and climate condition studied, it is required the use of the maximum dose of nitrogen (40.0 kg ha-1 N) and 78.9 kg ha-1 phosphorus, not requiring the addition of potassium.
