Abstract EN
An experiment was conducted at Al-Raed station in Abu Ghraib area to evaluate the performance of the combined machinery RAU and its effect on field efficiency (% ) traction efficiency (% ), bulk density (g.
cm-3), and percentage of soil moisture loss (% ).
Not clear.
The practical speed represented the first factor at three levels 4.06 km.
h-14.43 km.
h-1and 5.76 km.
h-1.
Such as the depth of the treatment, the second factor, at three levels (10-20-30) cm.
The split panels design within the complete randomized block design represented the statistical design used in the experiment with three replications.
The least significant difference was used to compare the means of the coefficients.
The results of the experiment showed that the first operationa speed4.06 km.
h-1achieved the highest rate of field efficiency of 72.76% the highest at traction efficiency of 71.28% and the lowest bulk density of soil at 0.938 g.
cm-3And the highest soil moisture loss 18.04% while the third speed achieved the opposite of the previous results.
The first treatment depth achieved the highest results for field efficiency at 71.92% the lowest results for bulk density 0.951 g/cm3and the highest soil moisture loss at 18.26% while the third depth achieved the opposite of the previous results.
The interaction between the depth of treatment and the process speed showed that the first depth with the first process speed achieved the highest rate of field efficiency 73.98And the highest value of traction efficiency 71.68% the lowest average bulk density of soil 0.816 g.
cm-3the highest average loss in soil moisture at 19.13% and the third depth achieved with the third speed in recording the lowest field efficiency 66.10% and the highest Average bulk density 1, 120g.
cm-3, and the lowest rate of moisture loss 14.76% while the lowest rate of drawing efficiency was recorded at the first depth and third speed 62.58%
