In the experimental area, two mulching experiments were
conducted: one with bagana (the straw resulting from the extraction
of the carnauba wax sheet) of carnauba (C. prunifera) and other
with black polyethylene plastic. In both, the plants were exposed to
different doses of micronutrients applied with two different types of
fertilization: soil fertilization and leaf fertilization (15 applications
every 28 days).
