Abstract :
In order to evaluation of solarization time and plastic color on germination of Amaranthus retroflexus and Sinapis arvensis in Estahban region, this study was carried out in a factorial arrangement based on randomized complete block design with three replications. Factors included solarization duration at 0, 15, 30, 45 and 60 days, and plastic color at Transparent, non-transparent and dark levels. The effect of solarization duration on total dry weight of weeds showed that with increasing solarization time, dry weight of weeds decreased and there was a significant difference between different treatments of solarization time The lowest dry weight of weeds (36.2 g / m2) was observed in 60 days of solarization and the highest dry weight of weeds (162.55 g / m²) was observed in control treatment Also, the darker the color of the plastic, the total dry weight of the weeds decreased. The highest dry weight (95.1 gr / m2) was obtained in transparent plastic and the lowest dry weight (24.25 g / m2) in dark plastic.
