چکیده

The peanut (Arachis hypogaea) is an important edible oil crop that plays a crucial role in strengthening global food and energy security, thereby contributing to sustainable development worldwide. The peanut crop encounters a significant challenge due to the proliferation of various weeds near the plants, particularly during the early growth stages when seedlings emerge ۷ to ۱۰ days post-sowing. Competing for sunlight, soil space, water, and nutrients, these weeds interfere with pegging and can reduce yields by up to ۷۰%. Given the limited peanut cultivation area in the country, implementing agronomic practices such as optimal plant density and planting patterns is essential to enhance yield. In addition to density, the spatial distribution of plants per unit area is highly important, as proper distribution of solar energy and increased absorption can improve crop performance. To maximize sunlight efficiency, an even and sufficient leaf canopy covering the ground is required, achievable by adjusting plant distribution along planting rows. Based on the points mentioned, the aim of this experiment was to examine the effect of planting patterns and weed management on seed count, pod number, and dry seed weight of in two peanut cultivars under the weather conditions of Kermanshah.
