Proper rows arrangement in an intercropping system is an important factor for reducing interferencebetween plants and better absorption of environmental resources. Effects of saffron–cumin intercrop-ping based on replacement series on growth, yield, quality and total land equivalent ratio (LERT) wasstudied as two-year field experiment based on a randomized complete blocks design arranged in factorialwith three replicates at Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, during 2013–2014and 2014–2015 growing seasons. Different planting densities of saffron (low, medium and high equal to64, 128, 256 corms m−2, respectively) and saffron–cumin intercropping (in proportion of 100–0, 75–25,50–50, 25–75 and 0–100) were considered as the first and the second experimental factors, respectively.Based on the results, interaction between saffron planting density and saffron–cumin ratio was significanton flower number and dried stigma yield. However, crocin, picrocrocin and safranal were not affected bysaffron planting density and intercropping ratios or their interaction. In each intercropping ratio, flowernumber and dried stigma yield increased with increasing saffron planting density. In the first and secondyear, reduction in cumin ratio in intercropping decreased cumin grain and essential oil yields. Nonethe-less, saffron–cumin intercropping could partly compensate yield loss. For instance, in the second year,cumin yield in 50% saffron + 50% cumin treatment was found to be 23.33% less than cumin monoculturetreatment. In both years of the experiment, the highest LERTwas observed in 50% saffron + 50% cumintreatment. Hence, this ratio along with high planting density of saffron (256 corms m−2) is recommendedfor saffron and cumin intercropping.
