Influence of babassu palm straw on the growth of spontaneous vegetation and the contribution of nitrogen through litter

Abstract

An experimental plantation was conducted with the intention of evaluating the efficiency of the
soil cover with babassu leaves as mulch cover for the control of spontaneous herbs. The field
experiment was carried out in the municipality of Pirapemas-MA, where samples of the spontaneous
flora were collected on the streets of planting, in plots involving three doses of babassu
straw. The survey of spontaneous plants was performed with quadrants, inserted randomly in
all plots and planting densities, in the collection of litter. The concentration of nitrogen was high
in the area with a palm density of 50%, becoming the ideal density for soil nutrient availability,
and in the treatments where single and double dose were applied, a reduction in the number
of Families of spontaneous herbs being this effect influenced by the coverage that avoided the
penetration of the light that are necessary for the germination of the majority of the seeds.
