abstract
The field experiment was conducted to study on weed management in irrigated wheat (Triticum aestivum L.) during rabi season of 2022-23 at wheat research station, SDAU, Vijapur (Gujarat). The experiement was laid out with randomized block design with total ten different weed management treatment including pre and post emergence weedicide with four replications. Result revealed that if we comparing different weed management treatment except weed free post emergence application of Clodinafop @ 0.06 a.i. kg/ha +Metsulfuron methyl @ 0.004 a.i. kg/ha (Premix) being at par with hand weeding @ 30 & 60 DAS, Metsulfuron methyl @ 0.004 a.i. kg/ha and pre emergence application of Pendimethalin (CS 38.7% Xtra) @ 0.75 a.i. kg/ha where significantly reduced the weed density and dry weight of weeds as compared to all other treatments. The post emergence application of Clodinafop @ 0.06 a.i. kg/ha +Metsulfuron methyl @ 0.004 a.i. kg/ha (Premix) significantly increased, all the growth, yield and yield contributing characters viz., length of spike, effective tillers per metre square, grain, straw and harvest index. While, 1000 grain weight and plant height recorded significantly higher by Metsulfuron methyl @ 0.004 a.i. kg/ha and Pinoxaden @ 0.040 a.i. kg/ha respectively, however no. of grains per spike does not affect significantly by different treatments. Thus, it is concluded that for effective weed control and higher yield application of post emergence Clodinafop @ 0.06 a.i. kg/ha +Metsulfuron methyl @ 0.004 a.i. kg/ha (Premix) herbicide applied at 25-30 days after sowing and for pre emergence herbicide application of Pendimethalin (CS 38.7% Xtra) @ 0.75 a.i. kg/ha after sowing of wheat but before application of irrigation in dry condition may be adopted in wheat crop.
