Abstract

Background and Objectives
This study was conducted to investigate the effects of different intercropping ratios of coriander and fenugreek on seed and essential oil yields, as well as to evaluate the productivity and benefits of various intercropping combinations of these two plants.

Material and Methods
The experiment was carried out as a two-factor factorial based on a randomized complete block design with three replications at the Research Farm of the Faculty of Agriculture, University of Zanjan, in 2022. The first factor included different additive intercropping ratios: 100% coriander + 20% fenugreek, 100% coriander + 40% fenugreek, 100% coriander + 60% fenugreek, 100% coriander + 80% fenugreek, and 100% coriander + 100% fenugreek, along with sole cropping of coriander and fenugreek. The second factor was different weed management conditions: full weed control, single weeding, and no weed control.

Results
The highest leaf area index, seed yield, biomass yield, and essential oil yield of coriander were obtained from the 100% coriander + 40% fenugreek, while the lowest values were recorded in the 100% coriander + 100% fenugreek. Similarly, the highest leaf area index, seed yield, and biomass yield of fenugreek were observed in sole cropping, and the lowest in the 100% coriander + 20% fenugreek.

Conclusion
The findings of this study indicate that in organic coriander production, lower densities of fenugreek in intercropping systems can serve as a suitable approach to enhance seed and essential oil yield of coriander.
