Abstract

Aim of this research is to develop a variable rate controller system includes mechanical part, electronic circuit, application map software and laboratory test system apply variable rate fertilizer application due to requirement of crop instead of constant rate of application used by farmers generally. Centrifugal fertilizer spreader with two discs, stepper motors, variable rate controller, GPS and variable rate application software were used as materials in this research. Developed variable rate controller and application software were improved. In addition, a laboratory test software was developed. Laboratory tests of the new control system were realised. 15-15-15 (N-P-K), %46 Urea, 20-20-0 (N-P-K) and %33 Ammonium Nitrate chemical fertilisers widely used by farmers for field crops were used in the laboratory tests. Developed system was worked without any problem.
