STUDY ON THE MECHANIZATION OF BEAN (Phaseolus vulgaris) CROP UNDER EGYPTIAN CONDITIONS

This study aimed to select the proper system of bean crop mechanization to achieve high yield, low grain losses with high field efficiency. The experiments were carried out using pneumatic planter and seed drill in planting operations in addition to the manual method, and tractor mounted mower was used in harvesting operation under different forward speeds and moisture contents compared to the manual method. Also, a Turkish threshing machine was used for threshing the crop at different drum speeds and seed moisture contents. From the obtained data it was concluded that; the pneumatic planter followed by tractor mounted mower and threshing by Turkish machine was considered the proper system for producing dry bean under Egyptian conditions, where as required minimum cost compared to the others. The seed moisture content of 14.86% and forward speed of 2.9 km/h were the proper conditions for harvesting dry bean crop. The threshing drum speed of 10.47m/s and seed moisture content of 11.33 % considered the proper values for threshing bean.
