Abstract

Two separated field experiments were carried out in Iranian Research Institute of Plant Protection, Karaj Field Station, in 2008 and 2009 to assess COVER CROPS affect on sugar beet weed suppression. In the first experiment, rye, wheat, barley and triticale were sown as COVER CROPS in autumn. In the second experiment, COVER CROPS (rye, wheat, barley and triticale for the first year and barley, wild radish, and berseem clover for the second year) were sown in spring and compared with three controls (including: weed free, weedy and chemical weed control). Experiments were arranged as randomized complete block design with four replications. Barley was recorded as the best treatment for weed suppression, in the first experiment in 2008 and 2009 with 22 and 78 g.m-2 weed dry matters, respectively. Root yield of sugar beet (29.3 and 48.7 ton.ha-1, respectively) did not differ significantly from control (weed free) in 2008 and 2009. In 2008, planting of COVER CROPS in spring had no satisfactory results and their effects on weed dry matter were similar. In the second year, barley was compared with wild radish and berseem clover, and results showed that barley was more suitable as cover crop, with 21.7 g.m-2 weed dry matter, sugar beet yield, however, was similar in different cover crop treatments.
