Abstract

Relative competitive ability of3 soybean cultivars (Willims, Clarck and Hobit) and redroot pigweed were assessed during entire growing season by using replacement series experiments .Decreasing the proportion of plant density resulted in increasing relative yield (RY) of soybean cultivars. Competition within species was higher than competition among" species. Relative yield of redroot pigweed was less than soybean cultivars due to higher inter- specific competition rather than intra- specific competition. Relative yield total more than 1 indicates niche differentiation between soybean and redroot pigweed. Also relative crowding coefficients (RCC) for soybean cultivars higher than unit, indicates higher inter specific competitive cultivars than potential redroot pigweed. Aggressivity (A) index in soybean cultivars were higher than redroot pigweed. However, in Hobit aggressivity was less than other cultivars.
