Weed suppression by the effect of the cover with Pennisetum purpureum and poultry manure in Sesame
| Resumo: | The sesame (Sesamum indicum) has great potential for southern Santa Catarina, but the expansion of the crop faces a problem in management, especially due to weed infestation. Therefore, the objective of this work was to evaluate the effect of poultry manure and different layers of napier grass (Pennisetum purpureum) on the suppression of weeds and sesame production components. The treatments were arranged in a factorial scheme (3x2), with factor A composed of different coverage layers (0, 2 and 4cm); and factor B by doses of poultry manure (0 and 3kg m-2). The evaluated variables were: weed identification and weed dry phytomass, at 15 and 30 days after seedling transplanting (DAT); and number of capsules and dry phytomass of crop. The increment of the level of mulching in the soil reduces the weed dry phytomass, increases the number of capsules and the dry phytomass of sesame, while the fertilization of poultry manure (3kg m-2) does not interfere with the evaluated components. |
