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.
