Reaction of redroot pigwed (Amaranthus retroflexus L.) plants to simazine
Janusz Lipecki
Simazine at the doses of 5 and 10 kg ha-1 a.i. caused a significant increase in the fresh matter and non significant increase in the height of Amaranthus retroflexus L. seedlings when compared with untreated plants. There were no significant differences in the weight of 100 seeds and in the content of mineral elements (except Mg) in plants treated with different doses of simazine. Preliminary measurements done in 1988 pointed out that the length of inflorescences increased after the use of simazine, especially in the dose of 10 kg ha-1 a.i.
