Nowadays, most of the planting machines that are used in Iran, do not have enough planting accuracy or because of having complex systems, require a lot of initial investment for farmers. These tools are offered at a high price and are not suitable for small farms that have low performance. In Iran, the method of planting chickpeas is mostly done manually, which requires spending a lot of time and money. Thus using such row crop planters will save costs and reduce the duration of planting. In this research, an automatic distribution system of a row crop chickpea planting machine was constructed and evaluated, and a new system was considered for the planter which automatically plant chickpea by relying on the uniform flow of seeds. For this purpose, the indicators including no planting, multiple planting, quality of nutrition and precision in planting distance were considered to investigate the uniformity and accuracy of chickpea planting. Tractor speed at three levels of 3, 5 and 7 km/hr and the distance between seeds at three levels of 5, 10 and 15 cm were used to evaluate the performance of the system. The results showed that the effect of speed on all indicators was significant at the level of 1%. Also, the effect of the distance between seeds on the indicators of multi-planting, nutrition quality and accuracy in planting distance was also significant at the level of 1%, however it had no significant effect on the no-planting index. In none of the indices, the mentioned variables had no mutual effect. Evolutionary polynomial regression was used to investigate the relationship between constant variables of speed and distance between seeds with distributed functional variables. This regression model was able to fit the relationship between variables with a high regression coefficient. According to the measured indices, the uniformity and precision in planting chickpeas with this automatic distributor was desirable.
