Effect of Intercropping on the Yield and Some Quantitative and Qualitative Traits of Fenugreek and Anise

Intercropping in many parts of the world، due to the efficient use and conservation of resources and enhance the quantitative and qualitative yield of medicinal and crop plants is important. In order to evaluate the effect of intercropping on yield and some physiological traits of fenugreek and anise in intercropping a field experiment was carried out in the agricultural research field of Yasouj University، during growing reason of 2011- 2012، as a randomized complete block design with three replications and ten treatments. Treatments included one row of fenugreek + one row of anise، two rows of fenugreek + two rows of anise، three rows of fenugreek + three rows of anise and monoculture fenugreek and anise by without weed control and weed control conditions. The results showed that intercropping treatments had significant effects on grain and biological yield of both plants and pure cultures of the two species in terms of both the presence and absence of weeds had the highest grain and biological yield. Treatments on grain and oil yield، percentage of the total protein and biomass nitrogen on fenugreek and anise essential oil and oil yield were significantly different from each other. Land equivalent ratio in all intercropping treatments was more than one and between 1. 04 and 1. 39، which was indicated superiority of a mixed culture than pure culture in the culture patterns. In general، single-row intercropping to monoculture، due to the improved quality traits and increase its usefulness is recommended.
