| Abstract | ||
| A field experiment was conducted at the Field Crops Research Station, College of Agriculture, Tikrit University, during the summer of 2024 to study the effect of planting dates and soybean Varieties on growth traits and yield. The experiment included eight Varieties and three planting dates (May 15, June 5, and June 25) using a Randomized Complete Block Design. Results showed that the June 5 planting date outperformed others, recording the highest plant height (82.34 cm), leaf area (825.78 cm² plant⁻¹), number of pods, seeds per pod, and seed yield (5.97 tons ha⁻¹). The "Shimaa" variety showed the best performance, achieving the highest seed yield (6.44 tons ha⁻¹). The interaction between planting date and variety was significant, with "Shimaa" planted on June 5 yielding the highest values in growth and productivity, reaching 6.87 tons ha⁻¹ of seed yield. | ||
