Blackgram

Weed Management

  • When blackgram is grown as an intercrop with sorghum, pigeonpea, pearlmillet, etc., the interculture given to the main crop is adequate.
  • When sown as a sole crop 1 or 2 weedings are required in the initial stages to keep the field free from weeds. However, one weeding 30-40 days after sowing is found to be enough.
  • The pre-emergence application of Basalin @ 1 kg a.i/ha in 800-1,000 litres of water keeps the field free from weeds for the first 50 days and thereafter the crop smothers the weeds.
  • It should be well incorporated in the soil before sowing.
  • Crop requires two hand weedings at 20 and 45 days after sowing but if hand weeding is not possible, pre-emergence application of Lasso at the rate of 1.5 litres a.i./ha keeps the field weed free upto 50 days and thereafter the crop smothers the weeds.
