In order to evaluate efficacy living mulch of Common vetch (Vicia sativa L.) on yield and yield
components of maize varieties (SC.704) an experiment based on a randomized complete block
design arranged as a split-split plot with four replications was conducted in Meteorology Station
of Fars Province, city of Firoozabad during 2015. Suppression of living mulch of Common
vetch were arranged in three times (4, 6, 8 leaf stages of corn by using 2,4-D herbicide in the
amount of 750 ml/ha) in main plot, and Common vetch density on Three levels (10, 20 and 40
plant m-2) With two levels no weeding and weeding in subplot, respectively. The most important
weed species in the experiment were Pink mustard (Eruca sativa ) and Field bindweed
(Convolvulus arvensis). Average total Weed density in weedy control condition was 133
plant/m2. With considering impact of different treatments on these weed was founded among
experiment s treatments only density 40 (plant m-2) living mulch of Common vetch had the most
effectiveness in decrease Pink mustard density and Field bindweed density than weedy control,
and this was caused decrease Pink mustard and Field bindweed population than weedy control.
