Abstract

Ñ  ABSTRACT   Ñ

 The model of the locally manufactured plastic mulch spreading machine was developed by adding a mechanism to extend a drip tube and testing its performance. The new model spreads the plastic mulch and carries out the process of burying the soil and covering the ends of the mulch to stabilize it, in addition to extending the drip tube on the surface soil in a straight path in the middle and under the plastic mulch. A field experiment was carried out in the village of Al-Hatriya in the Al-Qadmous region during the 2024 agricultural season to evaluate the performance of the developed model by studying the indicators of the degree of regularity of the plastic mulch, the degree of coverage, the regularity of the drip tube extension, and the amount of fuel consumption after calibrating both the height of pressure wheels and the depth of coverage device and speed of work. The results showed the following:

• The degree of uniformity of the plastic mulch spreads was inversely proportional to the speed and directly proportional to the depth of the coverage device, and the best values were 95.1% at the first speed of 1.5 km/h and the depth of 15cm for the coverage device.
• The degree of coverage was also inversely proportional to the speed and directly proportional to the depth of the covering device. The best values were 380% at the first speed of 1.5 km/h and the depth of 15cm for the covering device.
• An increase in the uniformity index of the plastic mulch brushes and the degree of coverage index after adding the drip tube extension mechanism.
• The index of the uniformity of the drip tube extension was inversely proportional to the speed and the height of the pressure wheels, and the best values were 82.7% at the first speed of 1.5 km/h and the lowest height of 35 cm.
• The drip tube extension uniformity index improved by 12.8% after adding the drip tube extension guide to the work unit.
• An increase in fuel consumption by 3.8 liters/ha after adding the drip tube extension mechanism.
