Raised Bed Machine with Six Planting Arrangement Models.

The use of cultivation techniques that can properly prepare the seedbed and cultivate the seeds at an almost uniform depth has become more necessary than ever. In this research, the plate subside test was used for modeling. In soil simulation, it was considered as an elastic body with two criteria: Mohr-Columb and Drucker-Prager. This experiment was performed using strip plots in the form of a completely randomized block design with four repetitions in the ۲۰۲۱-۲۰۲۲ crop year, in the field, uniformity of seed distribution and shedding were the percentage of seed germination and effective field capacity. The results showed that the crusader has a significant advantage in the four parameters studied compared to other flowers at the level of half a percent. Compared to other planters and in relation to the highest numbers obtained from the treatments, the cross-planter increased the uniformity coefficient of planting depth by ۷% the uniformity of seed longitudinal distances by ۲۳%, and the germination by ۲.۳% compared to other planters. The percentage of seed breakage was reduced by ۱.۲۵%. By changing the position from cast iron to plastic diagonally. The modeling results showed that the Drucker-Prager behavioral model with a ۹۳% correlation coefficient had a better agreement than the Mohr- Columb model and its magnitude and displacement in layers close to the load surface was higher and by moving to the lower layers of this the amount is reduced.
