| Abstract: |
| The experiments were performed in a factorial format with three factors: the forward velocity, the rotational speed of the dividing axis and the size of the valve opening with a completely random base design, and each experiment was repeated three times. In each experiment, the amount of fertilizer poured was compared with the desired value and the error percentage was recorded. The three forward speed factors (A) for the tests were 5, 7 and 10 km/h. Valve opening size (B) was done in three modes, ie in the first case the valve was completely open, in the second case it was 2/3 open valves and in the third case it was 1/3 open valves. Application rate (C) at three levels of 100, 150 and 200 kg/ha was also considered as the amount of fertilizer distributed. According to the obtained results, the effect of forward velocity (A) on the amount of fall at the level of probability of 5% is significant. The effect of application rate (C) and the interaction effects of forward speed and application rate (AC) as well as the interaction effects of application rate and valve opening value (BC) on the amount of shedding at the 1% probability level are significant. |
