Abstract
White grub attacks in Indonesia lead to the decrease of productivity of peanuts from 2.5 - 3.0 tonnes/Ha into 1.33 tonnes/Ha. Various control techniques that rely on chemical control is not successful in reducing the population of white grub. Soil tillage before planting is expected to provide an effective control technique. Research was conducted by collecting soil sample in 10 plots of cultivated land (9 m2 per plot), with three replicates. Soil samples were taken one day before and after first soil tillage and one day after second soil tillage by digging three holes in each plot diagonally (deep 20 cm, width 20 cm, and length 20 cm). Conventional soil tillage was conducted by one plowing, with a disk plow, followed by a leveling disk harrow. White grub eggs or larvae were counted. Soil tillage is unreliable to control the white grub in the absence of other control techniques. White grub population was not significantly reduced after the first and the second soil tillage. The white grub population tended to increase with the increase of vegetation density that provides organic material
