Description
Summary:Intraspecific competition in a dominant perennial grass, Dichanthium annulatum (Forsk) Stapf., of the grasslands at Varanasi has been studied at four different densities during 1970–1971 under pot culture conditions. Effect of competition, both on the individual plant as well as on the population, has been discussed in the light of certain ecophysiological parameters. Keenness of competition varies with density and age of the plant. Increase in density is detrimental to the individual's growth behaviour, particularly at the peak period of vegetative growth (210 days), while functioning of the population as a whole increases with enhancing density up to 135 plants/m 2.
