ESTIMATING RENAULT TRACTOR COSTS USING DIFFERENT DEPTHS AND AGRICULTURAL MACHINES

Abstract

The experiment was carried out in one of the fields of the Agricultural Research Department affiliated to the Ministry of Agriculture in Abu Ghraib in the year 2022 for the purpose of calculating the total costs of the Renault type tractor and studying the effect of three different equipment represented by the disc softener, masher and seeder and three levels of depths of 5 cm, 10 and 15 cm on the performance of the type tractor  (Renault has been studied) overall economic costs, The Randomized Completely Block Design (RCD) system was used, and the results were analyzed using the Least Significant Difference (LSD) method at the level of 0.05 and compared with the averages of the coefficients. The results showed the following:1- Changing the type of machine from disc harrows to packers and then to seeders led to a significant decrease in the total costs from 24119 to 24055 and then to 19793 (D.ha -1).2- Increasing the depth from 5 to 10 and then to 15 led to a significant increase in the total cost of the mechanical unit from 22521 to 22678 and then to 22768 (D. hectare -1).3- The overlap between the disc harrows and the depth of 15 cm led to recording the highest value in the total costs, which was 24245 (D. Ha-1).As for the overlap between the seed and the depth of 5 cm, it led to recording the lowest value in the total costs, and it was 19639 (D. ha- 1).
