Effect of Conservation Tillage Speed and Depth on Crop Residue, Soil Moisture and Soil Resistance

 Tillage implement and those which are made inside the country, and considering the importance of tillage depth and speed in different tiller performances, this investigation was carried out based on random blocks in the form of split plot experimental design. The main factor was tillage depth (10 and 20cm at both levels) and the sub factor was tillage speed, 6, 8, 10, 12 km per hour on four levels for Bostan Abad and 8,10,12,14 km per hour for HashtroudRegarding tillage speed effect for studies characteristics at 1% probability level (p < 0/01) remaining amount of plants was effective. From tillage depth effect in probability level of 5% (p < 0/05) on plant remaining amount was influential. The mutual effect of tillage amount of remaining plants on was significant at probability level of 1% (p < 0/01). In Hashtroud, effect of tillage speed remaining amount of plants at probability level of 1% (p < 0/01). Through an increase in tillage speed, remaining amount of plants Moreover, the optimum speed was concluded 10km per hour. Through an increase in tillage depth, the amount of remaining plants reduced. Tillage depth had significant effect on soil water content (p < 0/05). Regarding sampling depth effect on soil water content, was significant at 1% (p < 0/01) and 5% (p < 0.05) probability level, respectively. In Hashtroud, tillage depth effect on soil water content at probability level of 1% (p < 0.01). Depth of sampling was significant on humidity percent at probability level of 1% (p < 0.01). Through an increase in tillage depth, soil water content increases accordingly. The most appropriate tillage.
