EVALUATION OF HEAVY CHISEL PLOW PERFORMANCE IN DIFFERENT DEPTH IN TERMS OF SOME MECHANICAL PERFORMANCE INDICATORS

Abstract

This study was conducted to evaluate the performance for chisel plow at the end of January in during agricultural season ( 2018) In the area of Baweizah of the district of Talkif / Ninavah province which is located north east of the city of Mosul Which is far (13) Km about center of the city. The Soil texture was silty clay by using two levels of factory of level plowing, the first level was add the roller reducer on the chisel plow and the second level was remove the roller reducer from the chisel plow . Also two levels of depth plow .The first was (8-10 cm) and the second was (12-14 cm). to study their effect in some mechanical properties , the experience was factorial with three replication .the important results are in the following: excelled (add the roller reducer) in the following properties ( Volume of soil disturbed, Depth achieved ,The appearance tillage), while the level (remove the roller reducer) excelled in properties (Draft power ,specific resistance), while does not appear any moral differences in the following properties (Fuel consumption) . At same time excelled the depth (8-10) cm in the following properties (Fuel consumption, performance efficiency, The tillage appearance). While Second depth(12-14) cm excelled in the following properties (Volume of soil disturbed, specific resistance, Depth actual of plowing). while does not appear any moral differences in the following properties (Draft force) . Register The interaction between the first level tillage (add the roller reducer) and the first depth (8-10) excelled on the following properties (performance efficiency, The tillage appearance) while the interaction between the first level tillage (add the roller reducer) and Second depth (12-14)cm achieved moral superiority in the following properties (Volume of soil disturbed, Depth actual of plowing), while the interaction between the Second level tillage (remove the roller reducer) and the first depth ( 8-10) cm record moral superiority in the properties(Fuel consumption). while the interaction between the Second level tillage (remove the roller reducer) and Second depth (12-14)cm moral superiority in the following properties (Draft force, specific resistance) .
