Abstract

Thiswork was carried out to develop and evaluate a fertilizer broadcasting machine to be suitable for spreading small seeds such as linseed. The developed spreader was evaluated and tested at EL-Gemmiza Agricultural Research Station, EL-Gharbia Governorate under four forward speeds : 1.74 , 2.82 , 3.99  and 5.07 km/h, four disc revolving speeds of 270, 350 , 430 and 510 rpm ( 6.08, 7.88, 9.68 and 11.48 m/s ) and three ratio of feeding screw to land wheel speed ( kinematic parameters ) of 1.61 , 2.23 and 4.14 gave twelve rotating speed of screw which were 27.77 , 38.47 , 45.08 , 62.44 , 64.24 , 71.42 , 81.56 , 88.98 , 112.97 , 115.92 , 165.19 and 209.73 rpm. Spreader productivity, energy requirement and distribution uniformity had been determined. The results showed that, it is possible to use the centrifugal broadcast machine after adding feeding device and making some modifications on its motive power in spreading small seed crops. The optimum value for the operation conditions were obtained at forward speed 3.99 km/h, spinner speed 510 rpm ( 11.48 m/s ) and feeding screw speed 88.98 rpm (0.35 m/s kinematic parameter 2.23 ) were as given the best result of productivity rate (5.32 fed/h), energy consumption ( 16.37 Mj/fed ) and distribution uniformity with coefficient of variation 33.32% .
