Abstract

In order to evaluate the effect of rye infestation on some growth characteristics and grain yield of wheat, a field experiment was conducted in 1998 in Rokh Cool season Cereals Research Station of Torbat Haydarieye afflicted to Khorasan Agricultural Research Center. In this experiment, the effect of five levels of rye infestation [0% (control), 10% (25 plants per m2), 20% (50 plants per m2) 30% (75 plants per m2), 40% (100 plants per m2)] on two cultivars of wheat (Alamoot and C-73-5) was studied in a factorial randomized complete block design with four replications. Results showed that by increasing the percent rye infestation wheat height and the number of unfertile tillers increased. Factors such as number of fertile tillers, biological and grain yield decreased with increasing the number of rye plants. Biological yield of Alamoot and C-73-5 at 40% infestation decreased by 21. 9% (2. 29 T/h) and 22. 2% (2.91 T/h), respectively, compare with control. The grain yield of wheat at 40% infestation (100 P/m2) was about 52% of control yield. The presence of 100 plants/m2 (40% infestation) caused a grain yield reduction of 2.5% (3.31 T/h) and 55% (3.23 T/h) in Alamoot and C-73-5, respectively when compared with control. The experiment showed that the presence of 25 rye plants per m2 of wheat field is the threshold limit.
