An experiment consisting of eight treatments, viz., no weeding, Stomp 330E(pendimethalin), Igran 500FW (triazines), Authority 4F (sulfentrazone),Topogard 500FW (triazine + terbuthylazine), Sencor 70WP (metribuzin) andTreflan 4EC (trifluralin) was conducted in RCB design at Malakandher Farm,NWFP Agricultural University, Peshawar during Fall 2001 to see the impact oftreatments on potato and its weeds. Weeds dry matter was highest in no-weeding (486.4 g/m2) followed by Treflan (444.4 g/m2), both statistically atpar, whereas statistically lowest dry matter (273.1 g/m2) was found in hand-weeding. Crop height was maximum (28.64 cm) in hand-weeding but statisticallyat par with other treatments, except Treflan (18.56 cm) where plant height waslowest. Number of tubers did not differ significantly, though the number wasotherwise higher in Sencor (266941) and Topogard (264500) compared withother treatments. Potato yield was statistically highest in hand-weeding (14729kg/ha), followed by Topogard (14486 kg/ha) and Sencor (14219 kg/ha),respectively, however, these treatments were statistically at par with eachother. The remaining treatments resulted in statistically lower yield and werestatistically at par with each other.
