| Abstract:
An experiment was carried out to evaluate the effect of herbicides under different water levels on weed control and production of asparagus crowns in a volcanic soil of Chile. Herbicide treatments across irrigation line were trifluraline (0.5 and 1.0 kg a.i. ha-1), linuron (0.5 and 1.0 kg a.i. ha-1), and trifluraline followed by linuron (0.5 and 0.5 kg a.i. ha-1). The line-source sprinkler system gave different water levels: 6.0, 8.3, 12.5, and 15.0 mm hour-1 depending how far the plot was from the irrigation line. All treatments were compared with a weed-free check. Results showed that herbicides affected weed population until 4 months after spraying. No herbicide treatments reduced weed population as good as weed-free check did. Herbicide activity was not related with irrigation levels, and trifluraline (0.5 kg h-1 a.i.) had the best results on asparagus crown production, while trifluraline (1.0 kg ha-1 a.i.) was the best in crown quality. However, none herbicide treatment performed as good as hand weeded-free check. | |
