Abstract:

Common bean
production (Phaseolus vulgaris) is severely infested by weeds in
Ethiopia. Field
experiments were conducted in 2012 and 2013 at Ambo
University, Ethiopia, to determine the effect of
pre  emergence herbicide s-metalachlor on
weed dynamics and yield of
common bean (Phaseolus
vulgaris
)
in completely randomized block design with three replications. The
field experiments were comprised of 5 treatments including s
-metolachlor (dual gold) 1.00, 1.50
and 2.00 kg ha-1, weed free and weedy check
were used. The common bean in both years were infested with Amarathus
hybridus
L., Datura stramorium, Erucastrum arabicum Fisch and
May, Galinsoga parviflora cav., Ipomea ariocarpa, Nicandra spps,
Oxalis corniculate
L., Oxalis latifolia L. and Polygonum nepalense Meisn
. Among the treatments, hand weeding
standard check and s
-metolachlor at 2.00 kg ha-1
significantly reduced density and dry
weight of weeds during 2012 and 2013 years.Moreover,hand weeding and s-metolachlor
at 2.00 kg ha-1
significantly increased the plant height, number of pods per plant, and seeds
per pod as compared to other treatments. The highest grain yield was recorded
on hand weeding plot followed
by s
-metolachlor at the rate of 2.00 kgha-1. However, no significant
difference was observed between them, whereas, the lowest grain yield was recorded
on untreated plot (weedy check). Weed infestation resulted in a caused a yield reduction of 72.5% and 63.5% in 2012 and 2013, respectively. Pre- emergence application of s -metolachlor at the rate of 2 kg ha-1
was found to be more effective in controlling weeds and increased the c yield in
common bean.

Keywords: Common bean, s-Metolachlor,
Pre emergency
herbicide, Weed flora.
