Swiss chard (Beta vulgaris. flavesens) seedlings resistance and tolerance to selected soil applied herbicides

This study aimed to determine the effect of four herbicides; Alachlor, Metolachlor, Pendimethalin and Trifluralin; applied at five application rates and control, on selected Swiss chard growth parameters). The application rates of herbicides were 0.5, 1.0, 1.5, 2.0, and 2.5 l/ha plus control. The study was conducted in the greenhouse using a completely randomized design (CRD) with three replications. Thus, a total number of 21 treatments were replicated three times to give 63 pots for this study. The parameters measured were days of emergence, germination percentage, plant height, number of leaves, root length, and number of roots. A one-way analysis of variance was populated using SAS 15.0 and mean separation was done at p
