soil compaction treatments and tire-soil contact pressures on soil and
plant properties and dry matter yield of second crop silage maize were
investigated. Soil compaction was applied in the forms of the following
treatments; Compaction on Furrow Surface (CFS), Compaction on Furrow Bottom
(CFB), Compaction on Inter Rows (CIR) and non-compaction as a Control
(C). The tire-soil contact pressures were selected as 0.025, 0.051 and
0.076 MPa control treatment was 0.0085 MPa. After planting and before
harvesting; soil penetration resistance and soil bulk density were determined
as soil properties at different soil compaction treatments stated above.
Before and after harvesting period, as generative growth, plant stalk
diameter, plant height, single plant dry weight, percentage of corncob,
harvesting index and dry matter yield were determined. Soil penetration
resistance values changed in the soil depth of 0-10 cm from the 0.23 to
0.45 MPa after planting and from the 0.64 to 1.15 MPa before harvesting.
Also values changed 0.32 to 0.83 MPa in the soil depth of 10-20 cm after
planting and from 0.95 to 1.33 MPa before harvesting. C treatment gave
low mean values of soil penetration resistance in the soil depth of 0-20
cm. The lowest mean dry matter yield was obtained in CIR treatment as
8.39 Mg ha-1. The highest values obtained at C and CFS treatments
as 9.98 and 9.28 Mg ha-1, respectively. Compaction treatments
caused by press wheel increased soil bulk density and penetration resistance.
Dry matter yield of maize was affected by compaction treatments.]]>Altuntas, E., E. Ozgoz and O.F. Taser,2005553035ASAE,199744th Edn.,pp: 821-822pp: 821-822Bayhan, Y., B. Kayisoglu and E.
