| | Article Name : | | Effect of soil compaction on shoot and root
development and nutrients uptake of sesame plant | Author Name : | | ABELKARIM D. ELFADIL, HUSSAIN A. SALIH | Publisher : | | Bridge Center | Article URL : | | | 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. | Keywords : | | sesame, compaction, plant height, root length, shoot:root
