The experiment was conducted as a factorial design within a completely randomized block design with three replications in the Bile-Savar Moghan County, during the 2019-2020 and 2021-2022 in two agricultural year. The treatments included soybean planting dates (including May 15 and June 10) as the main factor and soybean cultivars (early-ripening (Williams), medium-ripening (L17) and late-ripening (DPX) genotypes) and soybean planting density among wheat (15 and 25 plants per square meter)) as the sub-factor. Results: The results showed that the highest number of seeds per pod, thousand-seed weight, and single plant weight were observed in the first agricultural year at a density of 15 plants per square meter. The highest soybean yield was also obtained on the delayed planting date of June 10 with a density of 25 plants per square meter with an average of 932.50 kg per hectare. Based on the results, the highest harvest index and biological yield were observed on the planting date of May 15 with 25 plants per square meter in the medium-ripening (L17) and early-ripening (Williams) cultivars, respectively. Also, the highest land equivalence ratio in the first and second agricultural years was obtained on the planting date of May 15 with 25 plants per square meter in the late-ripening (DPX) and early-ripening (Williams) cultivars, respectively. The highest productivity index of the first agricultural year was obtained in the delayed planting date of June 10 with a density of 15 plants per square meter in the medium-ripening variety (L17).
