This study was conducted during the 2025 at the Agricultural Research Station of the Field Crops Department, College of Agriculture, Tikrit University, in Salah al-Din Governorate, located at latitude 34.6°N and longitude 43.6°E growing season and aimed to evaluate the effect of planting dates and vermicompost levels on the vegetative growth traits of mung bean, with the goal of determining the optimal planting date and level of organic fertilization. The experiment was carried out using a randomized complete block design (RCBD) with a split-plot arrangement and three replicates to study two factors. The main plots represented three planting dates: May 15, May 30, and June 15, while the subplots represented three levels of vermicompost: 0, 2, and 4 tons ha⁻¹, applied before planting. The results showed a significant effect of planting dates on several studied traits. Planting on May 30th resulted in excelled plant height, number of leaves per plant, leaf area, leaf area index, and dry weight, registering averages of 89.98 cm, 78.62 leaves per plant, 4285.6 cm², 5.12  , and 98.99 g.plant^-1, respectively. The results also indicated that the application of vermicompost at levels of 2 and 4 tons ha⁻¹ resulted in a significant improvement in most traits, although no statistically significant differences were observed.
