摘要

Being a short duration and initially slow growing, blackgram suffers heavily due to infestation of weeds. Depending upon intensity and nature of weed flora, an average yield reduction of 30-50% has been reported due to weed competition (Mishra, 1997).Use of herbicides is advantageous and economical. Herbicides could affect root formation (Garcia and Jordan, 1969) and also change the effectiveness of the rhizobia, especially after long-term exposure to residues of persistent herbicides. A number of herbicides have been evaluated for their efficacy against weeds in blackgram, however, the information on the effect of these herbicides on nodulation and soil microflora is lacking. Therefore, the present investigation was undertaken.
