A field experiment was conducted at the Pulses Research Centre, Ishurdi, Pabna, Bangladesh under rainfed condition during Kharif-1 season of 1994-95 to evaluate the effect of weeding on yield and yield components of blackgram. Different weeding level had significant effect on grain yield and different crop characters.The highest grain yield (1.37 t/ha) was found in two weeding at 21 and 28 DAE which was identical to one weeding at 21 DAE and one weeding at 28 DAE. The lowest grain yield (0.90 t/ha)was obtained by no weeding i.e. control plot.

To evaluate the effect of weeding on yield and yield components of blackgram.
The field experiment was conducted at the calcareous Gray Flood Plain soil of Pulses Research Centre, Ishurdi, Pabna, Bangladesh under rainfed condition during Kharif-1 season of 1994-95 to evaluate the effect of weeding on yield and yield components of blackgram. The land was medium lhigh and soils was silty loam, having pH 7.5 containing 1.2% organic matter, 17 ppm N, 26 ppm P and 300 ppm K.There were four weeding treatments such as i)no weeding,ii)one weeding at 21 DAE,iii) one weeding at 28 DAE and iv) two weeding at 21 and 28 DAE.It was laid-out in a RCB design with three replications. Unit plot size was 5m x 4m. The dates of sowing was 7 September,1994.Fertilizers were used @ 20-40—20 kg/ha of N-P205-K20 as urea, tripple supper phosphate and murate of potash.The variety was used MAK-1.Weeding was done as per treatment.The crop was harvest on 16 November,1994 and data were collected from 10 randomly selected plants. Yields were estimated from an area of 6 m2 from each individual plot and converted into t/ha.The data were statistically analysed and means values were compared by Duncans Multiple Ranges Test.

It was found that one hand weeding at 21- 28 DAE is effective for weed control in blackgram in Kharif -1 season for grain yield.
