Abstract :

To study the effects of ecological weeds management by some of companion crops on agronomic traits of corn (single cross 504), an experiment was carried out in 2011 in Research Farm of faculty of agriculture at University Tabriz. The experiment was carried out in a factorial arrangement with the base of randomized complete block design in three repetitions. The treatments of this experiment included type of medical and cover plant in 4 levels (Clover, hairy vetch, basil and dill) as first factorial and time of cultivating cover and medical plant in tow levels (synchronic cultivation with corn and cultivation 15 days after corn cultivation) as second factorial. The results showed that the among companion crops, the cultivation of clover with corn had highest amount in all traits compared to other treatments because clover could closer rapid canopy that due to better control of weeds in the early stages of growth and decreased competition of inter specific. Also, synchronic cultivation companion crops with corn relation to cultivation 15 days after corn cultivation in all traits had highest amount, and lowest mean of density and weed biomass was observed in synchronic cultivation corn with clover. Hence with the attention to importance of life environmental issues and the above cost due consumption of herbicide  for weeds control has been recommend if possible for weeds control in farms has been used on the one of companion crops or medicinal crops instead of herbicide toxins.
