The present study was performed to evaluate the effect of cover crop on weed growth in different planting systems of sugar beet. This study was carried out as a strip split plot experiment based on randomized complete block design with three replications. Planting patterns (in two levels including single-row and double-row planting sugar beet) and type of cover crops (including barley, triticale, clover and oil radish ), the main factor and the time of removal of the cover crop (at two times of 4 and 8 leaves of sugar beet) was a secondary factor. The results showed that the two-row planting arrangement led to a decrease in weed growth and an increase of 7.27 tons per hectare in tuber performance and 840 kg/hectare in sugar yield compared to the one-row planting arrangement. Among the cover plant species, barley had the highest dry weight of the cover plant, the lowest frequency and dry weight of weeds, the highest tuber yield (38.71 tons/ha) and sugar yield (6.90 tons/ha). The removal time at the eight-leaf stage of sugar beet had the highest percentage of coverage and dry weight of the cover crop, the lowest frequency and dry weight of weeds, and the highest tuber yield (37.45 tons/ha) and sugar yield (6.77 tons/ha).
It was concluded that it is possible to obtain a higher yield by planting two rows of sugar beet and using barley cover plant and removing it at the eight-leaf stage of sugar beet
