Abstract:

Weed management studies were initiated in wheat on farmers` fields at 3 locations in the command area of Dir Area Support Program (DASP) during 2000-01 and 2001-02. Three treatments were employed in the studies viz. hand weeded check, herbicide Buctril-M and the unweeded check. Under the most infested site i.e Ajoo Talash about 8 times higher density of weeds was recorded in the two years of studies in the weedy check treated plots vs. Buctril-M. During 2000-01, as compared to the weedy check 12 to .74.64% increase in grain yield at 3 locations was recorded due to the application of Buctril-M. While, the hand weeding increased grain yield to the tune of 3 to 41% over the weedy check. A very lucrative cost effective gain was recorded due to the application of Buctril-M. The ratio oscillated between 2.23 and 7. B at the three locations. However, for the hand weeded plots the gain in yield was nullified with the additional cost on weeding, thus only a slight increase at Ajoo and Chokytan was recorded, while a severe loss was observed at Samar Bagh. During the subsequent year of study the gain in grain yield due to the application of Buctril-M was less wider ranging between 10 and 29% at 3 locations of studies. However, the cost: benefit ratio was still attractive due to herbicide application varying 1:2 and 1:5.2. The added advantage due to hand weeding was again lower as compared to herbicide use. Thus, the herbicide Buctril-M is recommended for the management of broadleaf weeds in wheat in the area of study.
