AbstractCommon planters in dryland conditions are planters that equipped with presses wheel that are suitable for planting in dry conditions. But the same press wheel in spring planting, such as dryland chickpeas in late March in cold areas where soil moisture is high, cause soil compaction and reduced yield. On the other hand, harvesting by hand is difficult and also in the preparation of land for planting wheat, the appearance of large lumps makes planting difficult. Therefore, hence due to the lack of access to a suitable planter in cold regions, chickpeas are sowing in small areas and in the traditional method (spraying the seeds and burying them with a moldboard plow). Increasing the yield by achieving a suitable planter can increase the area under mechanized pea cultivation in cold regions. To achieve a suitable planter, this project was carried out with the cooperation of the private sector in the Dryland Agricultural Research Institute in Maragheh for four years. The four planters, Barakat, Barakat Model BSK7, Aske Model 2200 and Sanayeh Keshtgostar Azarbayjan (SKA) were compared in four replications on a statistical basis of randomized complete blocks. The parameters of uniformity of planting depth, number of plants per unit length, height of the lowest pod and plant from the ground, number of pods per plant, grain and biomass yield and 100-seed weight were measured. The results of analysis of variance showed that except for plant height, the difference between treatments was significant in other measured parameters. The highest uniformity of planting depth and number of plants in the planting row was observed in SKA planter. But the highest grain yield with an average of 918 kg / ha due to having the largest pods per plant belonged to the Barakat planter. SKA, Aske and BSK7 planters were in the next ranks with 9, 26 and 30% decrease in grain yield compared to Barakat planter, respectively.
