Composição química-bromatológica do capim-tanzânia em função de doses de nitrogênio, potássio e enxofre

Resumo

The experiment was carried out at the Department of Animal Production of the Veterinary College, University of Goias, aiming to evaluate bromatological and chemical composition of Tanzania grass tissue in response to nitrogen (N), potassium (K) and sulphur (S) doses. The randomized blocks design in factorial scheme 3 x 3 with three replications were used. One-year of forage evaluation period was one year. Three cuttings were made in dry and rainy seasons. The forage were sampled with a 1 m2 square and the plants were cut 30 cm above soil. The vegetal material was weighed and indentified and then sent to laboratory, and bromatological analysed for CP, DM, NDF and ADF determination and for S, P, K, Ca, Mg, Zn, Cu, Mn and Fe. CP and FDN contents were not influenced by applied N:K and S doses in both evaluated periods. The percentage of MS varied in relation to N:K doses in dry period and FDA in raining season. P, Mg and Cu were influenced by N:K doses in raining season and S in dry period, only. K was influenced by S doses in raining season, and in dry season and K and Fe were influenced by N:K x S interaction.
