مقارنة أداء محراث مطرحي مع محراث حفار معدل في بعض مؤشرات الأداء

Abstract

The research was carried out in one of the fields in the Beit Al-Ayat area of ​​Tartous Governorate in the sixth month of 2024 with the aim of Comparing the performance of  the Moldboard plow with a modified chisel plow in some performance indicators, The experiment used a three-hull Moldboard plow and a three-hull chisel plow modified by installing fins on the stalk, Comparison was made through soil inverting, degree of soil fragmentation, soil bulk density, soil porosity, and fuel consumption. The results showed the following:

• The moldboard plow and the modified Chisel Plow achieved one degree of inverting of the soil, which was represented by the complete disappearance of the white powder from the surface of the soil and its inverting into the interior of the soil.

• The modified Chisel plow outperformed the moldboard  plow by achieving the highest degree of soil fragmentation, reaching (72.53%).• The moldboard plow outperformed the modified Chisel plow in achieving the lowest value of the soil bulk density rate, which reached (1.24 g/ ), and the highest value of the soil porosity rate, which reached (52.95%).

• The modified Chisel plow outperformed the moldboard plow by achieving the lowest fuel consumption rate of (0.644 L/ha).

• The modified Chisel plow is considered economically better than the moldboard plow, because it reduces the total fuel consumption rate by (0.774 L/ha).
