چکیده

ABSTRACT Spontaneous plants in vegetable growing areas significantly impact yield and costs, regardless of the adopted cultivation system. This study aimed to evaluate weed interference periods on profitability organic carrot under different sowing methods. Two experiments were set up [weed control coexistence, a randomized block design arranged as split plots (5 × 2), with five periods: 15, 20, 25, 30 35 days after sowing] two methods applied: direct water-conditioned sowing. Based production data technical coefficients, economic evaluation was carried out, calculation costs revenues. The highest net revenue obtained when area kept clean for 19 days. total increased linearly by R$ 0.33 m−2 each day control, while, coexistence treatment, it decreased -0.37 m−2. indicators cultivation.
