Abstract
A field experiment was conducted at the fields of a farmer in west of Maysan Governorate (latitude 30.51° N and longitude 47.06° E) during the fall season of 2023. The study aimed to investigate the effect of four mung bean (Vigna radiata L.) varieties (Local, Omrani, Parto, and Ghohar) cultivated at three different planting distances (20, 25, and 30 cm) on some growth traits and yield. The experiment was conducted using split plots in a randomized complete block design (RCBD) with three replicates, occupying the planting distances for the main plots, and the varieties for the sub-plots. The statistical analysis revealed significant differences among the varieties for most studied traits. The Ghohar variety (V4) outperformed the other varieties in most parameters, producing the highest seed yield of 2.346 tons ha⁻¹. Additionally, the Omrani variety (V2) recorded the highest number of seeds per pod, while the Local (V1) and Parto (V3) varieties showed the lowest values for the studied traits. The planting distance of 25 cm significantly improved leaf number, leaf area, and leaf area index, resulting in the highest seed yield of 2.304 tons ha⁻¹. Meanwhile, the 20 cm planting distance significantly increased plant height, reaching 52.21 cm. The interaction between the Ghohar variety (V4) and the 25 cm planting distance showed superiority in growth traits, such as leaf number, leaf area, and leaf area index, which translated into the highest seed yield of 3.017 tons ha⁻¹.
