Abstract

Different planting methods were used (Mechanical drilling, Mechanical transplanting and manual transplanting) and two rice variety (Giza 177 and Sakha 101) was used in this study to evaluate machine performance and water requirements. The experimental carried out in Rice Mechanization Center, Meet El-Dyba, Kafr El-sheikh, governorate during summer season of 2007.
Increasing the forward speed for all planting machines tends to increase the effective field capacity, fuel consumption rate, power consumption, energy required and slip ratio and decrease field efficiency and specific fuel consumption.
Also, the water requirement for different planting methods were (5686.2, 4500.8 and  5300.0 m3/fed ) and ( 5858.5. 5091.5 and 5460.0 m3/fed ) for rice variety Giza 177 and Sakha 101 under different planting methods, respectively. The grain yield was (3.300, 3.494 and 2.726 ton/fed ) and ( 3.420, 3.980 and 2.957 ton/fed ) for rice variety Giza177 and Sakha101 under different planting methods, respectively. The highest W.U.E value was obtained by using mechanical transplanting methods (0.571 and 0.582 kg/ m3) for rice variety Giza 177 and Sakha 101, while the lowest value was (0.514 and 0.542 kg/ m3 ) for Giza 177 and Sakha 101 under the manual transplanting .
