Abstract
Shoot dry weight and grain yield are reduced with the increase in plant density. The extent of the reduction at different densities in 3 crops was studied. The maximum of 44.4% grain reduction due to B. articularis competition in bajra (Pennisetum typhoides [=P. americanum]), 66.4% in guar (Cyamopsis tetragonoloba) and 22.5% in mung (Phaseolus mungo var. radiatus [=Vigna radiata]) were noted. The weed was crowded out and eliminated when the bajra plant density was increased to 15 plants/m2. Weed emergence after the fifth week did not affect the bajra crop yield, but at the third week, it reduced plant production. Guar production was reduced more by weed competition at all weed densities studied, than in the cases of the other two crops. Only early removal of weeds saved the yield loss in this crop. The yield reduction of mung was comparatively less, as only the persistence of weeds beyond 5 weeks reduced its yield. From summary
