Background & Objective: Considering the importance of sustainable agriculture and its role in increasing the quantity and quality of the product, the purpose of this research is to investigate the agronomic traits and economic indicators of safflower in the conditions of weed control and non-control.
Materials & Methods: In order to investigate the effect of weed control on the morphological traits and performance of safflower in intercropping with canola, a factorial experiment was conducted in the form of a randomized complete block design with 3 replications in year of 2014 in a farm in Maragheh city. The first factor included weed control at two levels (control and lack of weed control) and the second factor included the replacement mixed cultivation of safflower and canola with ratios of 1:1 and 2:1, respectively, and increased mixed cultivation of safflower and canola 100:50,100:75 and pure cultivation of safflower and canola.
Results: The results showed that the stem diameter, the number and length of lateral branches and the number of leaves per plant were the highest in the treatment combination of pure safflower cultivation with weed control. The highest seed yield was related to pure cultivation and complete weed control. With the increase of canola ratio, the morphological traits of safflower plant such as the number of leaves per plant and the diameter of the main stem decreased, but the plant height trait showed a significant increase.
Conclusion: Among the different cultivation patterns pure cultivation treatment with weed control had the highest seed yield.
