| In order to increase agricultural production, the government had realized not only new techniques in agricultural field, but also modified and improved the capability of the available techniques. In fact, using planters and seed – drills in sowing process is considered one of the most important agricultural operations, to achieve the final aim from applied mechanization in sowing seeds.Soil collapsing phenomenon behind the furrow opener of planter, before deposit seeds, is considered one of the problems encountered in plants, because it does not only cause un regular seed depth, but also it strongly caused a bad effect on seed germination ratio and final yield. Therefore, the aims of this research are: (1) To study soil collapsing phenomenon behind the planters furrow opener, this causes high scale variety in sowing seed depth. (2) To determine the effect of irregular sowing seed depth on germination ratio and the lateral scattering of seeding plants. (3) To develop and design a new furrow opener for minimizing soil collapsing phenomenon behind the furrow opener of planters, and controlling the furrow depth for improving the contact area between seeds and soil particles. The tested factors were angle of ridge (A), A1(20º), A2(30º) , A3(40º) and A4(50º, ) Planting forward speed (F), (F1 ( 3 km/h), ( 3.5 km/h) and ( 4 km/h) and The depth of planting (d): , d1 (2 cm), d2 (3 cm), d3 (4 cm) and d4 (5 cm). The results showed that the highest germination ratio of plants (99.1%) was recorded at the lowest forward speed (3 km/h), and the highest depth of planting (d4 = 5 cm.) for furrow opener (50º angle of ridge), while the lowest germination plants ratio (92.7%) was gained at the highest planting speed of (4.5 km/h) and the lowest depth of planting (d1 = 2 cm.) for furrow opener (20º angle of ridge). | ||||
