Selecting the proper systems for mechanization bean crop in new reclaimed lands [electronic resource].

Includes references.

Filed experiments were carried out to investigate some different mechanization systems for producing bean crop in new reclaimed land under Egyptian conditions. Seed bed preparation was investigated using chisel plow, moldboard plow and land leveler. Planting was investigated using both seed drill and planter comparing with the manual method. Harvesting was investigated using both self-propelled harvester and rear mounted mower at different forward speeds and different moisture contents comparing with the manual method. The obtained data revealed that, mechanical planting using seed drill, mechanical harvesting using self-propelled harvester are considered the proper systems for producing bean crop in new reclaimed land under Egyptian conditions. Sinus they recorded maximum productivity of 1.387 ton/fed and minimum cost unit of 48.3 L.E/ton. Seed moisture content of about 11.5 % and forward speed of 2.8 km/h are considered the proper conditions for harvesting bean crop as it recorded minimum seed losses of 3.41 %.
