INCIDENCE OF SPONTANEOUS PLANTS IN CULTIVARS OF CHILI PEPPER, PRODUCED IN DIFFERENT DEAD COVERINGS

Abstract

ABSTRACT: The use of mulch has shown to be an alternative in the cultivation of vegetables since it allows the reduction of soil temperature oscillation, evaporation of soil water, loss of fertilizers and correctives by leaching. The objective of this study was to evaluate the incidence of spontaneous plants in sweet pepper under different coverages. The experiment was conducted at the Federal Rural University of Amazonia, Campus Paragominas, in the experimental area of Horticulture. The statistical design was used in a 3x4 factorial scheme, using three chili cultivars: Ikeda, Rubi Gigante and Red square. The dead coverages used were: rice straw, sugarcane, soybean residue and the control. They were distributed evenly in the plots, with 5 cm of layer of each material. We evaluated the incidence of weeds in the production of sweet pepper, using the method of survey of the square type inventoried, with the aid of a wooden frame, with an internal area of 0.50 m², placed in the center of each plot. The dead cover with açaí stone presented a better trend in the control of weeds in cv. Ruby Giant and in cv. Ikeda hard shell of chili. While the soybean residue tended to be more efficient in the cultivation of cv. Red Square.KEYWORDS: Fruit vegetable, Rice straw, Soil cover.
