Abstract :Peanut (Arachis hypogaea L.) is one of the most important and economical oilseeds in the tropics and subtropics, playing a crucial role in both human nutrition and soil reclamation. This study aimed to evaluate the performance of various row planters and planting arrangements for mechanized peanut cultivation in the Moghan region of Iran using a randomized complete block design with six treatments and four replications over 2020 and 2021. The main objective was to identify the optimal planter configuration to enhance peanut yield. The treatments included different planting setups: T1 and T2 used a pneumatic single-row planter with 75 cm row spacing and 12 and 17 cm between plants, respectively. T3 and T4 applied a pneumatic twin-row planter (Tarashkadeh) with 75 cm between rows and 22 and 28 cm between plants, respectively, while T5 and T6 utilized a single-row planter with reduced row spacing of 50 cm and plant spacing of 25 and 30 cm. The results indicated that T4 and T3 provided the best horizontal uniformity of seed distribution (78.93% and 78.62%, respectively) and high emergence rates (94.23% and 93.08%). The twin-row configuration (T4) increased pod yield by 12.21% and 17.70% compared to the single-row patterns (T2 and T1). The twin-row planting system significantly improved plant density and pod yield, demonstrating its effectiveness over traditional single-row planting. Based on these findings, the use of a pneumatic twin-row planter (Tarashkadeh) with 75 cm row spacing and 28 cm plant spacing is recommended for farmers in the Moghan region to optimize peanut production.
