The soil moisture content has some considerable effects on plow draft and energy requirement, for cutting, elevating, and turning the soil. The degree of pulveri — zation is also affected by soil moisture content. The objective of this study was to find a range of soil moisture content in which the plow draft would be minimum and the degree of pulverization would be in an acceptable range . A randomized complete block design was used with 13 treatments representing different soil moisture contents replicated four times in a clay soil. It was found that the draft requirement increased with the increase of soil moisture content up to 20% ( dry basis ) and dropped gradually thereafter.
The pulverization actions were different for different moisture contents , but plowing at a moisture content of 14 to 16 percent (d.b. ) gave a more economically and technically acceptable degree of pulverization. It was concluded that for achieving a soil tilth for an economical see4bed prepration and minimizing the amount of wind erosion, the optimum soil moisture content for piowing operation was from 14 to 16 percent (d.b. ) . The scouring of the plow was also better in this range of the soil moisture content.
