Assessing the Supression on Weeds by Cover Plants in Amazonas, Brazil

June 19, 2021 Agricultural Sciences 0

Citrus plant productivity has not reached its full potential due to the action of several factors that have a direct impact on agricultural profitability.  Weed interference is one of the most important of these factors because it reduces crop productivity.  The crop’s sustainability is jeopardized by technological limitations and poor orchard management.  Some field studies have been motivated by compaction and erosion to evaluate weed management alternatives in the crop interrow, such as the use of cover plants to minimize losses and more rationally exploit natural resources.  The purpose of this study was to evaluate the effect of various cover crops on weed suppression in orchard. The study was carried out in a commercial orange production area in Rio Preto da Eva, AM, Brazil. A randomized block design with six treatments and four replications was used in the experiment. The treatments were control, millet, jack bean, forage turnip, brachiaria, millet + jack bean, and millet + jack bean. Weed density, soil cover percentage, total weed dry matter, total cover plant dry matter, and growth indices were all assessed (leaf area index, leaf area ratio, and specific leaf area). Except for forage turnip, cover plants produced a lot of dry matter and were good at suppressing weed growth. The was presented by Brachiaria and Jack Bean.
