Title: Effect Of Tractor Forword Speed On Field Performance Of Tillage Implements
Author: SHEERIN ADIL HUSSAIN AHMED, AHMED
Abstract: Effect of Tractor Speed on Field Performance of Tillage Impalements (M.Sc. Agric. Engineering Thesis) Sheeri¬n Adil Hussain Ahmed Abstract: An experiment was carried out during July 2010, at Gadaref University Farm, to study the performance of the wide level disk, chisel plough and the disk harrow, when used in three speeds (4.5, 7 and 9 km/h), and their effect on soil physical properties (soil moisture content, bulk density and infiltration rate), tillage depth and weeds control. The results showed that the highest theoretical and effective field capacities (2.7 ha/hr, 2.4 ha/hr, respectively) were recorded by the wide level disk. As tractor forward speed was increased from 4.5 to 9km/hr, the theoretical and effective field capacities increased by 50% when using the wide level disk, by 50% and 53.8% for chisel plough and by 49.8% and 48.8% for disk harrow, respectively. The highest field efficiency 88.6% was recorded by the wide level disk when compared with the chisel plough which recorded the lowest 78.2% field efficiency. The machines performance standard showed that the mean fuel consumption increased with increasing tractor forward speed. The mean fuel consumption rate increased by 68.9% for the chisel plough compared with the wide level disk and by 27.1% for the disk harrow. The results showed also that using tillage implements reduced the bulk density of the soil. The wide level disk recorded the highest percentage of weed reduction (94.3%) for all speeds when compared with the other machines. It was found that implement depth of cut decreased with the increased tractor forward speed. The results showed no significant differences between the tillage implements in moisture content, while there was a significant(PX05; 0.05) difference between speeds. The lowest values of the moisture content was recorded immediately after tillage by the chisel plough for the three depths when compared with the other machines; however, after 10, 20 and 30 days from tillage the chisel plough recorded the highest soil moisture content
