| その他の書誌記述: | Introduction. The weeds compete for water, light, and space with the coffee. Therefore, sustainable management practices must be carried out. Objective. To evaluate the effectiveness of weed management with ammonium nitrate and flaming in a coffee system. Materials and methods. This work was carried out from September 26, 2022 to January 10, 2023 at La Hilda coffee farm in San Pedro de Poás, Alajuela, Costa Rica. Two alternative weed control treatments were applied jointly, the first was ammonium nitrate diluted in water, at three doses (0, 150 and 300 kg/ha) and 15 days after spraying (dda) with this fertilizer, flaming was applied at three doses (0, 60 and 120 kg/ha). Applications were made on weeds present in coffee rows following a split-plot design, the large plot was made up of the ammonium nitrate doses, while the small plots were applied with the flaming doses. A chemical control was included with the herbicide glyphosate, also applied with flaming. Each treatment was randomly assigned and replicated six times. Results. The broad leaves were moderately damaged at 25 days after application of nitrate and 10 days after flaming. Both doses of ammonium nitrate slightly damaged Commelina diffusa, and the highest dose of ammonium nitrate without flaming caused moderate damage to broadleaf weeds; flaming without ammonium nitrate provided moderate initial damage to narrowleaf weeds. Conclusions. The herbicidal effect of ammonium nitrate was dependent on flaming but only on broadleaf weeds, C. diffusa was successfully controlled with glyphosate and flaming. |
