evaluate the effect of different intercropping arrangements of cumin (cuminum cyminum l.) and chickpea (cicer arietinum l.) on quantity and quality characterastis of species

in order to evaluate the effect of different intercropping arrangements of cumin and chickpea on seed yield and quality criteria of cumin an experiment was conducted in agricultural research station of ferdowsi university of mashhad in 2010 growing season. an experiment was conducted as split plot on the basis of complete randomized block design with three replicatons. the main plot included arrangement lines at 2 level, d1 1:1 (chikpea:cumin) and d2 1:2 (chickpea: cumin) and subplot included different densities at 6 level, p1:(100%cumin), p2: (50%cumin+50%chickpea), p3:(60%cumin+40%chickpea), p4: (80%cumin+20%chickpea), p5: (100%cumin+20chickpea), p6:(100%chickpea).the results showed that between different intercropping treatments, seed yield, biological yield and harvest index in treatment d1p2: (50%cumin+50%chickpea) was suitable. the highest percentage of nitrogen was obtained from treatment d2p4. was not observed any significant effect on seed essential oil. between intercropping treatments, highest essential oil yield was obtained treatment d2p2. the highest land equivalent ratio (1.23), was obtained in treatment d2p2: (50%cumin+50%chickpea) and the lowest (0.90) in treatment d1p4: (80%cumin+20%chickpea) intercropping.
