Abstract
The main objectives of the present study were :1-to evaluate the distribuation pattern of two different machines during fertilizing operation under local conditions.2- to study the effect of spinner and forward speed,fertilizer type and application method on the distribuation pattern.3-to determine the optimum speed of the spinner and the machine that will give areasonably even distribuation of fertilizer.4- to compare fertilizer seed drill and centrifugal fertilize distribuator (the spreader) for the yield components and field performance characteristics.
