Depth of sowing for seed spices are kept very shallow (1 to 3cm). Therefore, furrow openers commonly used in seed drills or planter are not very well suited for sowing of seed spices. Some of the spices seed e.g. cumin, coriander and fenugreek are highly sensitive to germination, if proper depth of sowing is not maintained. Even a small layer of soil over the seed affects the germination. Therefore furrow opener is very important component to ensure proper seed and soil contact as well as proper seed placement depth of these seed spices. The effects of three operating speeds (1.5, 2 and 2.5 km/h), tip cutting thickness (2, 3.5 and 5 mm), depth of operation (15, 25 and 35 mm) and tilt angle ∝ (30, 90 and 130) on draft requirement and furrow back fill percentage were evaluated for optimization of furrow opener for the planting seeds of coriander, fenugreek and coriander. The optimized and predicted value of parameters matched with the F2 furrow opener on the basis of criteria set for optimization of furrow opener. The furrow opener F2 maintained better furrow backfill percentage.
