| Abstract:
In order to improve the method and reduce the cost of cultivation of tuberose and gladiolus, the effectiveness of 4 herbicides in controlling weeds were studied. Pre-plant application of atrazine (2-chloro-4-ethylamino-6-isopropylamino, 1,3,5-triazine) at 3.0 kg a.i./ha caused the maximum reduction of weeds in tuberose field resulting in the highest yield (10.2 tonnes/ha) of good quality flowers. The corresponding yield from unweeded control plants was only 5.8 tonnes per hectare. The most effective herbicide in controlling the weeds in gladiolus field and promoting the growth and flowering of the crop was found to be oxyfluorfen(2-chloro-1-(3-ethoxy-4 nitrophenoxy)4-(trifluoromethyl) benzene) applied at the rate of 0.5 kg a.i. per hectare. Pre-plant soil spray with this herbicide markedly reduced the weed population and gave the highest yield of 221.1 thousand spikes per hectare as compared to only 162.3 thousand spikes produced in the unweeded control plots. | |
