Saffron is one of the most critical and valuable medicinal plants. The lack of mechanized planting of saffron corm and the high costs of labor in the limited planting time is one of the problems in the cultivation of this medicinal plant. The present study aimed to construct and evaluate a machine that can plant saffron corm at the desired intervals without having the corms damaged. For this purpose, first, a five-row planter machine with the ability to plant 5 to 10 tons of saffron corms per hectare was designed and developed. Then, under field conditions, two container volumes (full and half full) and two planting velocities (3 and 6 km/h) were examined using different planting indices. In the machine's structure, a continuous flow spoon chain feeder was installed in the bottom of the corms container and led the corms to the furrowers by five outlet ducts. The results of saffron corm planter evaluation performed in field conditions showed that the efficiency of the spoon chain feeder is suitable. The measurement of planting traits showed that with increasing velocity and decreasing the container volume, the distribution uniformity of corms around the mean of the obtained distances and around the set distance, uniformity of corm depth and feed quality index decrease; but the none-planting and multiple-planting indices and coefficient of variation of intervals increase. This machine can be replaced by labor and it is better to use it at a speed of 3 km/h and with a modified container.
