Abstract
Planting pattern plays a crucial role in peanut production. To investigate and compare row planters with different planting arrangements for mechanized peanut planting and to select the best planter in order to increase peanut yield in the Moghan region, the present study was performed in the Ardabil Agricultural and Natural Resources Research and Education Center (Moghan Agricultural Research Station), using a randomized complete block design with six treatments and four replications for the two years 2020 and 2021. The treatments were as follows: T1 and T2: planting by pneumatic single-row planter with spacing of 75 cm between rows and 12 and 17 cm between plants, respectively; T3 and T4: planting by pneumatic row planter with twin-row planter (Tarashkadeh) with spacing of 75 cm between rows and 22 and 28 cm between plants, respectively; and T5 and T6: planting by pneumatic single-row planter with spacing of 50 cm between rows and 25 and 30 cm between plants, respectively. Results revealed that T4 and T3 treatments had the highest horizontal uniformity of seed distribution (78.93 and 78.62%) and emerging percentage (94.23 and 93.08%). The twin-row planting pattern provided a zigzag cultivation that could prevent poor emerging planting in a single-row plant. More plants per unit area in twin-row cultivation treatments increased the pod yield compared to single-row cultivation. It can be concluded that planting with a pneumatic twin-row planter (Tarashkadeh) with a spacing of 75 cm between rows and 28 cm between plants is more desirable and could be recommended for Moghan farmers.
