تأثير أعداد و مواعيد الحراثة بنوعين من آلات الحراثة في حاصل الحنطة (Triticum Durum)‎ في محافظة نينوى

Abstract EN

The research includes the study of tillage systems by using vertical disc plow and heavy disc harrow and the number of times the procedure tillage the first one (comparison) autumnal plowing only, the second are after the harvest and autumn plowing , the third after the harvest, mid-July and tilling the autumn and the impact on pulling force KN, fuel consumption L/ha, fuel costs Din/ha, porosity%, the actual depth cm, the number of plants/m2, plant height cm, weight (1000) grain g and yield kg/ha.

Results indicated superiority of heavy disc harrow in less pulling force,less fuel costs that lead to less total costs compared with vertical disc plow while record interaction between the Vertical disc plow and tillage three times superiority in the remainder characteristics studies while record interaction between the heavy disc harrow tillage one time (comparison) less results for chara- cteristics studies.
