| Abstract | ||||
| The plant requires optimum soil- air- water relationships from the time the seed is planted. Five different plowing and three field experiments were carried out in Gemiza, El-Gharbia government, (clayley soil) during three successive agricultural seasons of 2006/2007, 2007 and 2007/2008. In three seasons three crops were planted, The study showed the decrease of percentages of soil particles after tillage comparing to the soil particles before tillage at 0-15 cm depth. The percentage of decrease was 5.13%, 4.08%, 1,25%,and 0.87%with (M-R),(2ch-w),( R ), and (ch-R)treatments, respectively. Available water was decreased with (M-R), and (2ch-w). the percentage of decrease 1.19%,and 1,1%, respectively at depth 0-15 cm .other treatments the percentage of available water was increased. The percentage of increased Was 0.2%, o, 41%, and 0.04% with (ch-R), (R), and no tillage, respectively. | ||||
