Study on the mechanization of Caraway crop production under Egyptian conditions

Field experiments were carried out to investigate some different mechanization systems for producing caraway crop under Egyptian conditions. Seed bed preparation was investigated using chisel plow, mould board Plow, rotary plow and Land Leveler. Planting was investigated using two types of seed drills (Colorado and Tye) machines comparing with the manual method. Threshing operation was investigated using threshing machine at different drum speeds, and different seed moisture contents. The obtained data revealed that, selecting the proper method of seed bed preparation (chisel plow one pass + land leveler) gave the best soil properties. Mechanical planting by seed drill (Colorado) comparing with seed drill (Tye) and manual method is considered the proper system for producing caraway crop under Egyptian conditions as it recorded the highest productivity was (865 kg/fed). On the other hand seed drill (TYE) required minimum cost of unit production(103.75 L.E/Mg) .Drum speed of 12.56 m/s (600 r.p.m) and seed moisture content of (7.72%) are considered the proper values for threshing caraway crop as they recorded maximum efficiency and minimum energy.
