This research was carried out in order to evaluate the biochemical and agronomic traits of dryland chickpea intercropped with dragon’s head in Saqqez city (Kurdistan province). It was conducted as a factorial split-plot experiment, arranged in a randomized complete block design, with three replications during the 2021-2022 cropping year. Treatments included three planting times (autumn, expecting, and spring) as first factor, three chickpea cultivars (Saral, Nosrat, and Anna) as second factor and five cultivation patterns [(pure chickpea), (25% L. iberica: 100% chickpea), (50% L. iberica: 100% chickpea), (75% L. iberica: 100% chickpea), and pure L. iberica cultivation (100% L. iberica). The highest leaf chlorophyll a and b contents were obtained in winter with intercropping of %100 Nosrat chickpea + %50 L. iberica and planting ratio (%100 chickpea +% 25 L. iberica), respectively. The highest leaf carotenoid content was obtained in spring with planting ratio of %100 Saral chickpea + %75 L. iberica. The highest water use efficiency was obtained in winter, in the Nosrat variety, and in pure cultivation. The land equivalent ratio in all intercropping patterns was more than one, which showed the superiority of L. iberica and chickpea intercropping compared to pure cropping.
