For plowing an important role in improving the qualities of soil and improve the quality of plowing in order to prepare the cradle of appropriate seeds and provide the appropriate conditions for germination by improving the qualities of soil physical and give the appearance of plowing and roughness well and if the chosen method of planning the field for tillage used and the tractor and machine occasion. The main objective and the basic behind the development of an effective model for planning field is to reduce the amount of transportation field is the number of revolutions of others operation thereof and the distance traveled in the circulation and the amount of movement of others operating within the field of all elements of on-productive of valuable time and energy that must be disposed of if at all possible [[Hunt, D. R. ]. Hunt,D.R. shows that substantive improvements in can be made in the field efficiency by analyzing and changing the model for planning and field operations that depend on the area and shape of the field. As well as a signal that there are variables that must be taken into account when determining planning model of efficiency, for example actual width of Plough, along the groove and speed of tillage, the actual speed of the conduct of on the pillow as well as the field width and the length of the field. Daniel and the signal that it is a necessary calculate time it takes to tillage and mobility and end grooves Dead to estimate the efficiency of the form field layout. Daniel also found that the fields are long and rotations fast and machines widescreen and high speeds have a significant impact on the actual field capacity. Daniel explained that there should be an appropriate time and location for the rotation of the machines on the field and the pillow also concluded

RESULTS AND DISCUSSIONS Influence the Field Patterns and Forward Speed of the Tractor in the Pattern Plowing Efficiency Table (2) influence the field Patterns and forward speed of the tractor in the Pattern plowing efficiency, as observed significant differences when changing field pattern of spaced pattern in convergent pattern as fall plowing efficiency of 58.63% to 53.48% for the reduction rata of 8.78%. This is due to the total time for plowing in a convergent pattern was higher than the spaced pattern and the limited of grooves consisting, Also achieved average speed forward of the tractor effect significantly as increasing the speed forward of 5 .5 to 6.3 and then to 7.5 km/h to increase the efficiency of plowing pattern from 49.33 to 52.83%, an increased rate 6.62% and then rise to 58.3% by increased rate 9.38% .may why decrease total time for plowing when the increase speed forward of tractor. While there was significant effect when interaction between field Patterns and forward speed of the tractor in the Pattern in plowing efficiency. Were obtained at the highest efficiency of 66.30 % when interaction between spaced pattern and forward speed 7.5 km/h. And less Pattern efficiency 49.33 % when interaction between convergent pattern and forward speed 5.5 km/h.

Where table noted the presence of no significant differences when changing field pattern of spaced pattern in convergent pattern, We also note the presence of significant differences at the forward speed of the tractors increased speed from 5.5 to 6.3 and then to 7.5 km/h as decrease average of plowing depth from 24.66 to 20 .83 cm, decrease rate 15.5% and then to 18 cm, decreased rate13.58% decrease rate. The reason for this is that plowing depth actual influenced by increasing forward speed as the relationship between them is usually inverse the more the forward speed the less depth tillage. While there was significant effect when interaction between field Patterns and forward speed of the tractor in the Pattern in plowing efficiency were obtained at the highest Plowing depth of 25.33 cm when interaction between spaced pattern and forward speed 5.5 km/h. And less Plowing depth 17.33 cm when interaction between convergent pattern and forward speed 7.5 km/h.

As well as between the table and the presence of significant differences when increasing the average forward speed of the tractor from 5.5 to 6.3 and then to 7.5 km/h to decreased fuel consumption rate of 69 .52 to 53.23 L/ha decreased rate of 23.4% and then 30.86 L/ha decreased rate 42% because increase in fuel consumption with decreased forward speed of the tractor that has made low-speed depth plowing largest in as of high-speed increase then load factor. While there was significant effect when interaction between field Patterns and forward speed of the tractor in fuel consumption. Were obtained at the highest fuel consumption of 75.44 l/ha when interaction between spaced pattern and forward speed 5.5 km/h.

Table 6 through notes there are significant differences when changing field pattern with decreased energy from 184.85 kw.h/ha to 137.9 kw.h/ha decrease rate 25.39%. May be it's because access to the highest power at spaced pattern and because of increased fuel consumption rate, and that a positive correlation relation between energy requirement and power. Through the same table shows there is an influence significant at change the forward speed of the tractor where the energy requirement decreased from 235 .0 kw.h/ha to 161.5 kw.h/ha decreased rate 31.2% at the forward speed to increased from 5.5 to 6.3 km/h, and then reduced 87.55 kw.h/ha down rate 45.78% when increasing speed 7.5 km/h, There was significant differences when the when interaction between field Patterns and forward speed of the tractor in Energy requirements.

appearance tillage decreased diameter less than 10 cm from 8.88 to 7.55 cm by decreased rate 14.97%, as well as showing the presence of significant differences when change the forward speed of the tractor from 5.5 to 6.3 and then 7.5 km/h ,were down blocks soils with a diameter of more than 10 cm from 11 .5 to 7.66 cm/m2 by decreased rate 33 .39% and then 5.5 cm/m2 by decreased rate 52.1 %. The reason for lower number of blocks soils increase the speed to the high speed works to increase speed throwing and hitting the blocks soils distance beyond the slow speed and thus dismantling blocs soils have the best and number less and this is consistent with what he referred Banna (1986) to the increased speed work to increase ejaculation blocks soils leading to increased coefficient disassembly. While there was significant differences when interaction between field Patterns and forward speed of the tractor in appearance tillage. Were obtained at the appearance tillage of 12.66 c m/m2 when interaction between spaced pattern and forward speed 5.5 km/h. And less appearance tillage 5.00 cm/m2, when interaction between convergent pattern and forward speed 7.5 km/h.

CONCLUSIONS From the above study the following conclusions can be drawn 

As observed significant differences when changing field pattern of spaced pattern in convergent pattern as fall plowing efficiency of 58.63% to 53.48% for the reduction rata of 8.78%.

Increased the efficiency of tillage pattern when increase the forward speed of the tractor, when 5 .5 to 6.3 and 7.5 km/h to increase the efficiency of plowing pattern from 49.33 to 52.83%, and 58.3% respectively.

The results showed that there is a no significant difference to the plow depth and appearance of plowing when change the pattern of tillage.

The reason for this is that plowing depth actual influenced by increasing forward speed as the relationship between them is usually inverse the more the forward speed the less depth tillage.

Increased Slip percentage of the tractor when increase forward speed of the tractor.

Tables 5 show a significant difference when change the field pattern on the average fuel consumption, where decreased from 58 .17 to 44.23 l/ha decreased rata 23.9%. Through Table 6 and significant differences when changing the plowing pattern and reduced energy requirements at the increased speed forward.

Interaction between field Patterns and forward speed of the tractor significant differences on a Pattern plowing efficiency , Plowing depth , fuel consumption , energy requirements, Slip percentage of the tractor, Field efficiency and appearance tillage.
