The objective of this study was to evaluate the response of the application of
nitrogen on the grass of forage yield Mombaça and its nutritional quality, subjected to
two sources of nitrogen fertilizers and four doses of nitrogen in the soil and climate
conditions of the city of Araguaína, Tocantins. The experimental design was a
complete randomized block design with three replications, with treatments arranged in
a factorial arrangement of 2 x 4, consisting of two sources of nitrogen (BUN and
Novatec N-max) and four nitrogen rates (20, 40, 60 and 80 kg N / ha) plus an additional
treatment by repetition (zero dose N). They were analyzed Dry Mass Production of
fodder (MSF); and crude protein (CP). Analyzed variables were subjected to analysis
of variance by PROC GLM of the statistical program Statistical Analysis System (SAS,
2007). MSF productivity of Mombasa grass increased linearly with increasing N rates
applied to the two sources of nitrogen used. There was a significant difference in
productivity between sources, especially the Novatec source N-max. It was found that
the increase was 51% in average productivity with the implementation of this source.
The sources and doses of nitrogen did not provide significant influence (P> 0.05) on
the crude protein (CP) in the dry matter of the leaf blade of Mombasa grass, with an
average of 8.03%. |
