In Iraq, rice (Oryza sativa L.) is a significant staple crop and its yield in the southern parts is highly dependent on the date of the planting as well as the cultivar type. This research was carried out to assess the impact of various planting dates on growth, yield, and yield components of various rice cultivars grown in the field in southern Iraq. The field experiment was based on a split despite plot design that was carried out in the summer season in 2025 within a randomized complete block design that had three replicates. Main plots were divided by three planting dates, D1 (1 June), D2 (15 June), and D3 (1 July), whereas subplots had four rice cultivars (Anber 33, Furat 1, Yasmin, and Amber AlqueliBaraka). Plant height, the amount of tillers per hill, the leaf area index, days to 50 percent flowering, days to physiological maturity, the number of panicles per square meter, the grains per panicle, the percentage of unfilled grains, 1000 grains weight and grains yield were recorded. Findings revealed that the planting date was found to have a significant influence on most of the growth and yield traits. The highest yield of grains was observed with Mid-June planting (D2, approximately 6.3 t ha 0 -1), then early planting (D1, approximately 5.7 t ha 0 -1), and lastly, late planting (D3, approximately 4.6 t ha 0 -1). Furat 1 and Yasmin had the best grain yields because they had more grains per panicle and panicle count whereas Amber Al Unless, had the best 1000ngthgrain weight. Anber 33 had reduced grain yield although it is also of importance based on its aromatic value. A strong interaction between the date of planting and cultivars showed a difference in the response of the genotypes with the environmental conditions conjoined with a particular date of planting. Based on the study the researchers recommend that high yielding rice cultivars like Furat 1 and Yasmin which are planted around mid-June in combination with rice would enhance productivity under the southern Iraq climatic conditions.
