| Abstract | ||||
| The objective of this study was to evaluate a 97:-.:" beet topping machine. Fielri experiments were conducted at Sakha Agricultural Research SThtion, Sugar Beet Crop Res. Dept., Kafr EL-Sheikh Governorate i..,.ring the two winter seasons of 2004 and 2005 using sugar beet variety (Farida). Experiments were carried out using sugar beet topping machine to determine the effect of forwarri speed, flail speed and topping height on topper performance (over topping, under topping, untopped, broken beet a:tr., topping performance), power, energy requirements and topping cost. The results showed that by increasing the forward speed from (1.8 to 5.0 Km/h) tends to increase the over topping from (2.50 to 3.0%), under topping (2.40 to 4.20%), untopped (2.60 to 4.0%), broken beet (6.50 to 9.90%), effective filed capacity (2..40 to 3.80 fed/h) and power requirements (14.5 to 18.0 kW).The results also showed that by increasing the forward speed from (1.8 to 5.0 km/h) leads to decrease the topping efficiency (95.0 to 92.0%), energy requirements( 6.04 to 4.74 kW.h/fed.) and topping cost ( 20.8 to 13.3 LE/fed.) at topping height of 5 cm. Also, the flail speeds and topping height of 3 cm take the same above-mentioned trend. | ||||
