Abstract :
This study was conducted to assess the effect of different soil compaction levels on the establishment and growth of sesame. Four compaction levels were used, namely, 1.2, 1.4, 1.6 and 1.8 g/cm3 as well as the control (0.95 g/cm3). The average plant growth parameters were found to be increased as the compaction level is increased. At the compaction level 0.95g/cm3 the seed-soil contact is week so the plant did not absorb enough moisture and nutrients from the soil. This effect was reduced when the compaction level is increased to 1.20g/cm3. The reduction of plant growth parameters under the compaction level 1.60 g/cm3 and 1.80 g/cm3 may be attributed to inability of roots to penetrate in the deep layers to absorb moisture and nutrients. The ratio between the shoot and root mass reached its maximum under the compaction level of 1.40g/cm3. Increasing the compaction level decreased the nutrient uptake. The lowest values in the control and 1.2 g/cm3 levels indicate that some compaction is needed to give a good seed-soil contact so as to be able to absorb moisture and nutrients. It can be concluded that soil compaction significantly affect plant growth, some soil compaction is needed for good seed-soil contact, but excessive compaction will impede root penetration.
