Abstract 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. |
