Abstract

This experiment was conducted to evaluate the COMPETITION relationship of CANOLA cultivars and WILD MUSTARD at the agriculture research station of golestan province during 2006-2007 growing season. The experimental design was a factorial arranged in RCBD with three replications. Experimental factors were CANOLA cultivars (Zarfam, Hayola330, Option500, and Rgs003) and four WILD MUSTARD densities (0, 4, 8 and 16 plantlm2). Linear reciprocal and yield loss models were fitted and their coefficients were used to interpret COMPETITION relationships of CANOLA cultivars and WILD MUSTARD results revealed that Zarfam, cultivar had the lowest coefficient of reciprocal model than other cultivars for both of grain yield and biological yield. Also, result indicated that interspecific COMPETITION of CANOLA cultivars was different and the highest value belonged to Zarfam cultivar. Our results based on yield loss models confirmed that biological yield decreased less than grain yield (Grain yield was more susceptible). Comparison of hyperbolic yield loss models showed that relative leaf area model with the highest value of R2, was more capable to predict yield loss of CANOLA cultivars. The relative damage coefficient (q) of relative leaf area model showed that WILD MUSTARD was more competitive than CANOLA (q> 1).
