Abstract :
A field trial on weed control in wheat was conducted at Agricultural Research Station, Chitral (NWFP-Pakistan), during 2004-05 using split plot arrangement of treatments. Three seeding rates (100, 125 and 150 kg ha-1) were assigned to main-plots while four herbicides (bromoxynil+ MCPA @ 0.45, clodinafop-propargyl @ 0.04, fenoxaprop-p-ethyl @ 0.75, isoproturon @ 1 kg a.i. ha-1) and a weedy check were allotted to subplots. Maximum weed control (79%) and minimum weed biomass (1086 kg ha-1) were observed in bromoxynil+MCPA followed by isoproturon (77 % and 1157 kg ha-1, respectively) as compared to the biomass in weedy control (3770 kg ha-1). Similarly, grain yield (2504 kg ha-1) and thousand grain weight (41 g) were the best in bromoxynil+ MCPA followed by isoproturon (2291 kg ha-1 and 40 g, respectively) as compared to weedy control (1406 kg ha-1 and 37 g, respectively). Thus, the best weed management and yield were recorded in plots with bromoxynil+ MCPA @ 0.45 kg or isoproturon @ 1 kg a.i. ha-1 post emergence and a seeding rate of 125 kg ha
