The present work was elaborated with the intention of evaluating the best management
of fertilization after a defoliation on morphological, agronomic and structural
characteristics of the Piatã grass (Urochloa brizantha cv Piatã). (0, 3, 7, 14, and 21
days) with four replicates per five-year period with four replicates per year. A leaf
elongation taxon (TALF), stem elongation rate (TALC) did not have significant
significance (P> 0.05) for the management of fertilization after a defoliation. These
variables are directly linked to the plant set and to the phyllochrome, which did not
have statistical statistics (P> 0.05). A leaf senescence rate (TSF) was significant (P
<0.05), showing the treatment from 21 days to the greatest, with a value of 9.6 mm
day-1. The SPAD index was relevant in this experiment, showing that the plant was
photosynthetically, finding values of 39 units, respectively for treatments 7 and 21
days, respectively. Another variable, which had a significant response (P <0.05) for the
rest period, which was 39 days for treatments 7; 14 and 2, showing a direct relationship
with a canopy structure of the plots, and showing a Time demand for the plant to be
recovered. The management of fertilization is fundamental to show that there are many
long for application, directly influence the physiological and photosynthetic structure of
the plant. |
