Abstract

Soil compaction has adverse effects on soil physical properties and hence on crop yield. It hinders crop root development, increases soil resistance and bulk density, decreases pore size and volume and finally infiltration of water into soil. In order to study the effects of subsoiling on soil physical properties and wheat yield, an experiment consisting of 5 treatments was conducted. The detail of each treatment was as follows: (1) S1P1, subsoiling to a depth of30-35 Cm plus moldboard ploughing, (2) S2P1 subsoiling to a depth of 40-45 Cm plus moldboard ploughing, (3) S1P0 only subsoiling to a depth of 30-35 Cm, (4) S2P0 subsoiling to a depth of 40-45 Cm, and (5) S0P1 only moldboard ploughing (Control). Before conducting the experiment, bulk density, cone index and intake rate were measured. These measurements were replicated after the first irrigation in each plot. Soil layering, texture, and Organic Carbon were determined in the experimental site. Finally, the wheat yield from each plot was measured. The results showed that subsoiling caused reduction in the bulk density and soil cone index and increased the basic intake rate and wheat yield. The best treatment in this study, in view of decreasing soil compaction was S1P1 which caused decreased the cone index, bulk density 12.8 and 4.1, respectively and increased the wheat yield up to 3.8. The S1P1 treatment caused and increase in basic intake rate up to 2.4 relative to basic intake rate prior to irrigation.
