Resumo: | The phosphorus deficiency and the natural acidity of Brazilian savannah soils contribute to the low productivity of Brazilian livestock raising. This research evaluated the effects of liming levels and phosphorus sources and levels in dry matter production of Tanzania grass (Panicum maximum Jacq. cv. Tanzania). The treatments were divided into groups 1 (G1) and 2 (G2). G1 evaluated three liming levels - no liming and liming to reach 30% and 60% base saturation (0, 1.12, and 2.64 t/ha, respectively) – and three phosphorus sources – single superphosphate, Yoorin thermophosphate and Arad hyperphosphate. G2 evaluated the same liming levels and five phosphorus levels – 0, 30, 60, 120, and 240 kg/ha of P. In G1 no interactions were observed between phosphorus sources and liming, nor were liming effects. Significant differences were found for phosphorus sources: grass yield was higher under single superphosphate than under Yoorin thermophosphate or Arad hyperphosphate. Dry matter production in G2 didn't differ between liming levels and no interactions were observed between phosphorus and liming levels. However, there were significant differences among phosphorus levels, with maximum dry matter production for 172.8 kg/ha of P. This result confirms the importance of phosphorus fertilization to achieve high yields in Brazilian soils. KEY-WORDS: Phosphorus; liming; forages; tanzania grass. |

A deficiência de fósforo nos solos brasileiros, aliada à acidez natural dos solos de cerrado, contribuem para os baixos índices produtivos da pecuária nacional. O objetivo deste trabalho foi avaliar o efeito da calagem e de diferentes fontes e dosagens de fósforo na produção de matéria seca do capim Tanzânia (Panicum maximum Jacq. cv. Tanzânia). O experimento foi dividido em dois grupos, G1 e G2. No grupo G1 avaliaram-se três níveis de calagem (sem correção e com correções para elevar a saturação de bases para 30 e 60%, com doses de calcário de 1,12 e 2,64 t/ha, respectivamente) e três fontes de fósforo (superfosfato simples, termofosfato Yoorin e hiperfosfato de Arad). No grupo G2 foram avaliados os mesmos três níveis de calagem e cinco doses de fósforo (0, 30, 60, 120 e 240 kg/ha de P). No G1 não houve interação entre as fontes de fósforo e a calagem, nem ocorreu efeito da calagem. Houve, contudo, diferenças significativas entre as fontes de fósforo, sendo o superfosfato simples superior ao termofosfato Yoorin e ao hiperfosfato de Arad. A produção de matéria seca no grupo G2 não foi influenciada pelos níveis de calagem. Contudo, houve diferença significativa entre os níveis de fósforo, com a máxima produção de matéria seca obtida com 172,8 kg/ha de P (395,6 kg/ha de P2O5). Não houve interação significativa entre calagem e dosagens de fósforo. Esse resultado reafirma a importância da adubação fosfatada para a produção, nos solos dos cerrados.
