Comparison between the draft force requirements and the disturbed area of a single tine, parallel double tines and partially swerved double tines subsoilers

摘要

A field experiments were conducted to compare the field performance of three subsoiler combinations using the draft force requirement and the disturbed area as comparison parameters. The subsoiler combinations are single fine, parallel arranged double fines and partially swerved double fines. The three subsoiler combinations were tested using four operating depths (30, 40, 50, and 60 cm) with and without wings in silty clay loam soil of moisture content (13.54%). The experiment design was randomized complete block design (4 x 2 x 3) with four replicates. The means of the treatments were compared using RLSD at probability level of 1%.
