چکیده
to evaluate yield and productivity indices of maize and sugar beet intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with three replication at hamedan province in nahavand, in 2013. the planting ratios were 100:0, 75:25, 50:50, 25:75 and 0:100 (maiz: sugar beet) using replacement method. results showed that intercropping had significant effect on yield and some yield component of both crops. the root-yield, sugar sterling, melas-sugar, content purity and sugar yield of sugar beet as well as shoot height, no. row. ear-1, kernel. row-1, 1000 kernel weight and grain yield of maize were significantly affected by different planting ratios. calculation of land equivalent ratio (ler) revealed that planting ratio of 25:75 (ler= 1.09) and 75:25 (maize:sugar beet) (ler= 1.08) had the highest efficiency by 9% and 8%, respectively. calculation of area time equivalent ratio (ater) revealed that planting ratio of 25:75 (maize:sugar beet) (ater= 1.03) had the highes efficiency. maize in the planting ratio of 75:25 had the highest relative crowding coefficient (ka= 7) as dominant crop and sugar beet had the highest rcc (kb= 3.88) in the ratio of 25:75 (maize:sugar beet) at the dominant crop.
