Abstract :

To evaluate the effect of cover crops including sorghum, Persian clover and fenugreek on potato yield and weed population, an experiment was conducted as complete randomized block design with four replication in Shiraz University, Research Station of Agriculture Faculty, in spring and summer of 2012. The treatments control with and without weed control measures, and mentioned cover crops cultivated with potato. After weedy control, the less weed dry matter possessing plots was observed in potato-clover compound planting. Sorghum-potato and fenugreek systems were in the last places. Fieldbind weed, redroot pigweed and lambsquarters as dominant weeds had the least population in the sorghum-potato treatment and afterwards in the clover and fenugreek. All treatments reduced potato tuber yield and there was no significant differences between them. On the whole cover crops can be used for weeds management of potato farms as a none chemical option.
