Abstract
A field experiment was conducted during the agricultural season 2012 - 2013 in clay soil to study the effect of use two types of plows on on growth components and yield of wheat, two varieties ( Begal and sham 6) and two types of plow (mold board and disc plow ) with three replicate used, The characteristic studded in experimen. , Plant height , length of spike, number of seeds per spike, Number of spikes per unit area , weight of 1000 kernel, yield of wheat RCBD design, SAS program used to analysis the experiment, begal variety was surpassed on plant height, spike length , and yield. Disc plow was surpass on plant height, spike length, number of spike -1, and yield The interaction shown the variety bigal with disc plow gave the best result in plant height, spike length, harvest index and yield which it gave 1817.8 kg /h.
