原始语种摘要: Although soil compaction has been reported as one of the most serious problems in mechanized sugar cane production, its impacts on soil physicochemical properties and plant growth and sugar yield have not been quantified in the Ethiopian Sugar Estates. A field experiment was conducted in 2016 at Metahara Sugar Estate with the objective of evaluating the effects of initial soil moisture content and number of tractor passes on compaction and resulting impact on selected soil physicochemical properties and sugarcane growth parameters and sugar yield. The field experiment consisted of factorial combinations of compacted soils at three different soil moisture levels (on 4th, 8th and 12th days after irrigation) and six tractor traffic passes (0, 4, 8, 12, 16, and 20 passes) which were...
