Development of the manure fertilizing machine to improve its distribution pattern for spreading different

1. The experimental laboratory results of the fertilizer broadcasting spreader reveal that optimum distribution pattern and high degree of fertilizer uniformity can be achieved under the following conditions :- Spinner peripheral speed of about 13.08 m/s (500 rpm).- Forward blade angle of +15°.- Spinner dip angle of zero degree.- Spinner height of 50 cm.- Straight C- shape blade.- Gate opening of 16.62 cm2.2. The experimental field results concluded to a definite recommendation of using manure fertilizing machine after development for manuring and chemical fertilization at a forward speed of about 4 km/h to achieve uniform distribution pattern, optimum fertilizer application rate and high crop yield of maize.
