  The effect of different herbicides applied at different timings viz. 30, 45 and 60 days after sowing (DAS) of wheat crop was studied for controlling weeds. Herbicidal treatments were Assert (Imazamethabenz-methyl) 0.30, isoproturon 1.12 kg alone and buctril-M (bromoxynil+MCPA) 0.72 kg+topik (clodinofop) 0.37 kg, logran (trisulfuron) 0.64 kg+topik (clodinofop) 0.37 kg, 2,4-D (2,4-D ester) 1.20 kg+topik (clodinofop) 0.37 kg and puma super (phenoxyprop-ethyle) 0.75 kg+2,4-D (2,4-D ester) 1.20 kg a.i. ha-1. A weedy check was also included for comparison. The analysis of the data revealed significant differences among the times of application for biological yield and grain yield. Similarly significant differences were recorded for herbicidal treatments in traits like spikelets spike-1, 1000 grains weight (g), biological yield (kg ha-1) and grain yield (kg ha-1). The interaction of the times of application and herbicides was significant for spikelets spike-1 and for grain yield. Maximum number of spikelets spike-1 and heavier 1000 grains weight was observed in plots treated with buctril-M+topik mixture, while minimum in weedy check plots. Biological and grain yield (kg ha-1) were higher in plots treated with buctril-M+topik and logran extra+topik while lower biological and grain yield were in weedy check plots. Buctril-M+topik proved to be the most economical herbicides giving maximum return of Rs. 24631 ha-1, if applied 45 DAS in wheat.
