Abstract

A field experiment was conducted at the research station of plant pest and disease research Institute of Karaj, during 2003-2004 growing season. The aim was to investigate Interference of WILD OAT(Avena ludoviciana) on Yield and yield components of more and less competitive WHEAT cultivars. The experiment was arranged as a factorial experiment based on randomized complete block design (RCBD) with 4 replicates. Experimental factors were Rooshan (as less competitive) and Niknejad (as more competitive) WHEAT varieties, 3 WHEAT densities including recommended, recommended+25% and recommended+50%(300, 375 and 450 plants m-2 for Rooshan and 400, 500 and 600 plants m-2 for Niknejad resp.) and 4 WILD OAT densities (0, 25, 50, and 75 plants m-2).The results showed that Niknejad was the most competitive cultivar and Rooshan was the least competitive one in different levels of WILD OAT density. As WILD OAT density increased, yield of WHEAT decreased and the rate of yield decline was higher in Rooshan in comporison to Niknejad. Higher densities of WHEAT decreased yield loose. The presence of WILD OAT in WHEAT fields reduced fertile tiller, number of spike, seed per spike, seed per square meter and weight of 1000 seeds. Recommended and recommended+25% was optimum densities in Rooshan and Niknejad, respectively, when WILD OAT interference.
