EFFECT OF TWO PULVERIZATION SEASONS WITH TWO TYPES OF PULVERIZATION EQUIPMENT ON THE PERCENT OF ANNUAL WEED CONTROL AND SOME PHYSICAL PROPERTIES OF SOIL

Volume 37, Issue 4, Pages 174-179
AbstractThis research was included the effect of two seasons. winter and spring with two types of harrows. offset disk harrow and spring harrow on the percent of annual weed control. soil moisture content. bulk density. number of soil aggregates greater than 5cm/m2. cutting depth. cutting width. coefficient of cutting width. and the percent of slippage. Results showed that the spring harrow showed higher significance in the percent of annual weed control. cutting depth and coefficient of cutting width while the offset disk harrow showed higher significance in the number of soil aggregates/m2 and the percent of slippage. The effect of interaction between seasons and pulverization equipment was significant in all studied characteristics except the moisture content and bulk density.
