Abstract

Brazil is one of the largest meat producers in the world, with a herd of approximately 219,100,995 million head of cattle and is the largest producer of fattening on pasture. However, the fertilization of pastures in Brazil is not carried out with the necessary frequency, due to the high cost and time to recover the pastures. A pasture reform, with harrowing and new fertilization, can lead to an increase in the mass yield offered to the animals, as well as a longer grazing life, using any form of fertilization, whether organic, chemical or organomineral. The research carried out sought to verify the response to organic, organmineral and chemical fertilization, observing the performance of the Brachiaria brizantha Mg5 Xaraes pasture. The treatments studied were: T1 - Witness; T2 - organic fertilization (chicken litter); T3 mineral fertilization (4-20-10) and T4 - organmineral fertilization (210-5). Evaluations were carried out for Green Mass (GM), Dry Mass (DM), Plant Height (PH) and Relative Efficiency (RE). The evaluations took place at two different times: at 90 and 172 days after planting. Data obtained were subjected to analysis of variance and then to the Scott-Knott Means Test at a significance level of 5%, using the SISVAR statistical program. Fertilization application promotes higher Brachiaria brizantha Mg5 Xaraes mass yield. Organic fertilization and organmineral fertilization supplied Brachiaria's needs in the same way as mineral fertilization.
