The experimente was conducted on 16 December 2015 to 29 January 2016.
The objective of this research was to evaluate the fonts (urea agricultural and urea of
slow liberation) and doses (40 kg-1
e 100 kg-1
de N). The delineamento was
casualisado entirely with four treatments and three repetitions in outline of factorial
arrangement 2 x 2 with two variation sources: doses and fonts of nitrogen. It was
accomplished evaluations of productive characteristics as the agronomic and
structural characteristics. The rest period went smaller for the dose of 100 kg-1 N
with period 35 days. The Mass dries available total and mass dries of sheet to foliate
they were not influenced by the doses and sources of nitrogen, the relative value of
sheet to foliate, stem and dead material, where for stem and dead material had effect
in the increase in the dose of 100 kg-1 N with medium values of 11,37 and 3,51
respectively, and the sheet to foliate it presented better results for to smallest dose
40 kg-1 N with medium value of 96,24. The relationship leafs stem had significância
for dose of nitrogen 40 kg-1, where it presented medium value of 62,62. The tillers
density resulted in increase in the dose of 100 kg-1 of N with medium value of
1.975,5. The fonts of nitrogen urea of slow liberation and agricultural urea didn't go
decisive factor to increase of production of dry matter, in that sense the dosage of
nitrogen produces more answers in the characteristics of the morphologic
components as well as in the structural characteristics of the plants.
