Effects of Some Tillage Parameters on Soil Cone Index Using Disc and Mouldboard Ploughs.

Abstract

A study was conducted on the effects of soil moisture content implement speed and tillage depth on soil cone index using disc and mouldboard ploughs on loamy sand soils. Analysis of variance and Duncan’s multiple range tests shows that, moisture content, implement speed and tillage depth have significant effects on soil cone index. Further analysis revealed that, at 1.94m/s (7Km/h) implement speed, the soil physical properties (cone index) reduced to minimum considerably and usually maintain a constant value which equals the values recorded at implements speed of 2.5m/s (9Km/h) and 2.78m/s (10Km/h) . This shows that, the physical properties of soil required for good soil tillage could be achieved at implement speed of 7km/h.
