Population dynamics of herbaceous communities of certain areas around Pilani were studied during the one growth season (monsoon) of 1968. The analysis of habitat factors and interrelationships between the habitat factors and B. articularis population were also studied. Among about ten herbaceous associates in various localities, B. articularis. and Cenchrus biflorus are closely associated. An increase in the associates of the grass group reduced the B. articularis populations. In cultivated fields the ratio between weeds and the crop plants is found to be 7 : 1. Of the seven weeds for every crop plant, three belong to B.articularis. The population of B. articularis is limited by the fine sand content. Plants preference for sandy soils with pH near neutral is established. Populations showed negative logarithmic relationship with soil pH from 7.3 to 7.7.
