الملخص الإنجليزي

A study was conducted in the agricultural season (2013-2014) in one of the agricultural fields in Bauazh /Iraqi north , field assessment for the seeder with three traflan rates (Zero .650 .750) cm³/D , and two sorts of tine (modified tine opener .hoe tine opener) under two speeds (first 6.6 , second 8.3 )km/hr, by measuring some notes which included (slippage percentage , Fuel consumption , percentage of control , plants /m² , grain yield).The field before starting the experiment was divided according to the experiment design to the random sectors which carried out with three factories split-split block design with three replicates where the main blocks specified to traflan rates , the shape of tine opener are set on sub plot .

and the two ground speeds was under sub sub plot .

The following are the most important results of the study: The rate 650 cm³/D has surpassed significantly by achieving highest means No .of plants /m² and grain yield .Using the seeder with modified tine opener due to significant increasing in No.

of plants /m² , Percentage of control for dry weight of weeds and grain yield , while the hoe tine opener gave significant decreasing in (slippage percentage , fuel consumption) .The first speed 6.6 km/h due to significant decreasing of (slippage percentage and significant increasing of No.

of plants/m² , control of percentage for number and weight of weeds and grain yield.

Triple interaction between The rate (650cm³/D) and modified tine opener with first speed gave highest significant for N .

of plants /m² and grain yield , while the same treatment but with hoe tine opener gave lowest value on slippage percentage , also the Triple interaction between( 750 cm³/D) and modified tine opener with first speed gave significant increasing in percentage of control for dry weight.
